[0038] As used herein, the term hydrocarbon fluid may refer to a gas, a liquid, or a combination thereof.

II. General Architecture

[0039] Turning to FIGS. 1-11, various aspects of the system and method of the present inventive concept are illustrated. The system of the inventive concept provides a mobile and scalable modular design that allows for the treatment of sulfur compounds from hydrocarbon streams in a compact, mobile fashion. Moreover, the system and method provide an alternative to the significant capital and operational costs associated with permenant/fixed exotic catalyst based systems.

[0040] In FIG. 1, a schematic diagram is presented of a vessel 100 for reducing a concentration of sulfur-containing compounds in a contaminated hydrocarbon fluid 102, according to an illustrative embodiment. The vessel 100 includes an inlet 104 for receiving the contaminated hydrocarbon fluid 102 and an outlet (not shown) for discharging a purified (or scrubbed) hydrocarbon fluid 106. The purified hydrocarbon fluid 106 has a reduced concentration of sulfur compounds relative to the contaminated hydrocarbon fluid 102. Disposed within the vessel 100 is a liquid media 108 capable of reacting with one or more sulfur compounds within the contaminated hydrocarbon fluid 102. Non-limiting examples of the liquid media 108 include the PETROSWEET family of products supplied by Baker Hughes (e.g., HSO3507, HSW7334, HSW7336, etc.).

[0041] The vessel 100 also includes a mechanical contactor 110 disposed therein. The mechanical contactor 110 is operable to force contact between the contaminated hydrocarbon fluid 102 and the liquid media 108. In some embodiments, the mechanical contactor 110 serves as a barrier to the liquid media 108. In these embodiments, the contaminated hydrocarbon fluid 102 is forced through the barrier to contact the liquid media 108. For example, and without limitation, the mechanical contactor 110 may be a sintered permeable membrane in contact with the liquid media 108. During operation, the mechanical contactor 110 receives the contaminated hydrocarbon fluid 102, and via channels and/or pores therein, intimately disperses the contaminated hydrocarbon fluid 102 into the liquid media 108. In this manner, the mechanical contactor 110 provides homogenous-like mixing, thereby creating intense interaction between the contaminated hydrocarbon fluid 102 and the liquid media 108. The mechanical contactor 110 may also create an environment for separation through diffusion. The liquid media 106 may be selected in chemistry to allow rapid reaction with one or more sulfur compounds in the contaminated hydrocarbon fluid 102. Thus, the intimate contact allowed by the mechanical contactor 110 yields superior product usage, improves a reaction or contact interface as compared to conventional processes, and produces sulfur removal results not currently achievable through conventional technologies.

[0042] Referring now to FIG. 2, a flow diagram is presented of a process 200 for removing sulfur-containing compounds from a hydrocarbon fluid, according to an illustrative embodiment. The hydrocarbon fluid may be supplied from a source, represented by block 202, and includes one or more sulfur-containing compounds. In this state, the hydrocarbon fluid may be a sour product or a sour crude. The hydrocarbon fluid is separated into a gas component and a liquid component, as shown by block 204. Such separation may involve any type of process capable of separating a gas phase from a liquid phase, such as gravity draining, centrifugal action, sparging via carrier gas, reduced pressure take-off, change in temperature, and so forth.

[0043] The gas component of the hydrocarbon liquid is scrubbed to reduce a concentration of sulfur-containing compounds therein, thereby producing a treated gas component (or sweet gas). Scrubbing of the gas component may occur in a vessel analogous to the vessel 100 described in relation to FIG. 1. Scrubbing of the gas component is shown by block 206, which in some embodiments, may also involve the production of waste products. The treated gas componentshown by block 208may be stored, or alternatively, sent for subsequent processing or consumption. The waste products may be stored or sent for subsequent processing (see block 210). Similarly, the liquid component of the hydrocarbon fluid is scrubbed to reduce a concentration of sulfur-containing compounds therein, thereby producing a treaded liquid component (or sweet product). Scrubbing of the liquid component may occur in a vessel analogous to vessel 100 described in relation to vessel 100 of FIG. 1. Scrubbing of the liquid component is shown by block 212, which may also involve the production of waste products. The waste products may be stored or sent for subsequent processing (see block 214).

[0044] With respect to gas versus liquid treatments, it has been discovered that gas treatments provide little variability to approaches in view of operational parameters/variables. Separation occurs instantaneously with little additional separation or filtration required. Conversely, liquid treatments can have significant variability depending on operational parameters/variables. Additional upfront filtration and/or separation can be required to ensure that product is reasonably free of solids, and that condensable fluids will be separated (at operating conditions) prior to chemical treatment. It is also anticipated that additional separation may be required to allow for additional residence time in the separator than the gas treatment, along with the potential need for post treatment filtration potentially, e.g., water washing and/or clay/particulate filtration.

[0045] Turning now to FIGS. 3-4, these figures present flow diagrams of treatment systems for combined gas/liquid phase streams. The diagrams depict the basic phases of treatment for mixed streams, as well as individual gas-only (or vapor-only) streams. It should be noted that with any of these systems, depending upon the commercial terms required, the systems could represent initial stages of treatment. For example, and without limitation, if easily removed contaminates are present (e.g. hydrogen sulfide), such contaminants may be removed in a separate contactor or scrubbing unit, prior to introduction into the aforementioned systems. Such pre-treatment may prevent contamination, reaction, or rapid saturation of specialty chemistries used for the treatment of the more difficult to remove sulfur compounds. Alternatively, such treatment could be part of an intermediate- or post-treatment process (e.g., after a separation process) to ensure that the resulting product is within contractual commercial terms.

[0046] FIG. 3 presents a flow diagram of a process 300 for removing sulfur-containing compounds from a liquid portion of a hydrocarbon fluid, according to an illustrative embodiment. In the process 300, a source 302 supplies the hydrocarbon fluid (or sour product) to a heat exchanger 304, which may be a condenser configured to condense liquid petroleum gas (LPG), liquid natural gas (LNG), or both. A knock-out vessel 306 separates the hydrocarbon fluid into a gas portion (i.e., sour gas) and the liquid portion (i.e., sour liquid petroleum). The liquid portion is processed in a chemical injector 308, which injects a chemical into the liquid portion. The liquid portion (with the chemical) is then transferred to a treatment contactor 310. The treatment contactor 310 may be analogous to the vessel 100 described in relation to FIG. 1. The treatment contactor 310 aids the chemical in removing sulfur compounds from the liquid portion, which exits the treatment contactor 310 to enter a separation vessel 312. The chemical returns to the chemical injector 308 via a recirculation loop 314. The separation vessel 314 removes undesired components from the liquid portion to produce a sweet hydrocarbon product. The separation vessel 314 may be a polishing scrubber to remove residual sulfur-containing or other compounds (e.g., hydrofluoric acid). In some embodiments, the sweet hydrocarbon product is transferred into storage.

[0047] FIG. 4 presents a flow diagram of a process 400 for removing sulfur-containing compounds from a gas portion of a hydrocarbon fluid, according to an illustrative embodiment. In the process 400, a source 402 supplies the hydrocarbon fluid (or sour product) to a heat exchanger 404, which may be a condenser configured to condense liquid petroleum gas (LPG), liquid natural gas (LNG), or both. A knock-out vessel 406 separates the hydrocarbon fluid into a liquid portion (i.e., sour liquid petroleum) and the gas portion (i.e., sour gas). The gas portion then traverses a particulate filtration unit 408 to remove contaminate particles therein. Other types of contaminants may also be removed (e.g., liquid droplets). The gas portion then enters a primary scrubbing unit 410, which may be analogous to the vessel 100 described in relation to FIG. 1. The primary scrubbing unit 410 produces a first-stage cleansed gas, which enters a secondary scrubbing unit 412. The secondary scrubbing unit 412 is operable to produce a polished gas, which may be transferred for sale or storage for subsequent use. In some embodiments, the secondary scrubbing unit 412 is analogous to the vessel 100 described in relation to FIG. 1. In other embodiments, the secondary scrubbing unit 412 is configured differently than the vessel 100. For example, and without limitation, the secondary scrubbing unit 412 may configured to remove acidic gases in the first-stage cleansed gas (e.g., hydrofluoric acid).

[0048] Turning now to FIG. 5, a schematic diagram is presented of a system 500 for treating a hydrocarbon fluid to reduce a concentration of sulfur compounds in a naptha-containing portion of the hydrocarbon fluid, according to an illustrative embodiment. The system 500 may also reduce a concentration of sulfur compounds in other portions of the hydrocarbon fluid. The system 500 includes a compressor deck 502 configured to receive a treated hydrocarbon gas stream. FIG. 6 presents a schematic diagram of a system 600 for reducing a concentration of sulfur compounds using reactors 602, 604 analogous to the vessel 100 described in relation to FIG. 1. The reactors 602, 604 are fluidly-connected to the compressor deck 502 of FIG. 5 and are operable to supply the treated hydrocarbon gas stream thereto.

[0049] Referring now to FIG. 7, a schematic diagram is presented of a system 700 for reducing a concentration of sulfur compounds in a hydrocarbon fluid, according to an illustrative embodiment. The system 700 includes a first treatment contactor 702 (or first reactor) and a second treatment contactor 704 (or second reactor). The first treatment contactor 702 and the second treatment contactor may be analogous to the vessel 100 described in relation to FIG. 1.

[0050] Turning now to FIG. 9, a schematic diagram is presented of a system 900 for reducing a concentration of sulfur compounds in a hydrocarbon fluid, according to an illustrative embodiment. FIG. 9 depicts the hydrocarbon fluid as butane, however, this depiction is not intended as limiting. The system 900 includes a vessel 902 operable to remove sulfur compounds from a stream of butane. The vessel 902 is analogous to the vessel 100 described in relation to FIG. 1. It will be appreciated that the vessel 902 includes a combination of a selected chemical and a mechanical contactor to provide homogenous-like mixing, thereby creating an intense interaction between the selected chemical and the stream of butane. This intimate contact yields superior product usage and an improved reaction/contact interface as compared to conventional processes.

[0051] Additionally, as depicted in FIG. 11 the process/system can have multiple iterations for achievement of commercial terms. In FIG. 11, based on these specialty chemistries used, a regeneration step can be incorporated, using heated hydrogen, nitrogen or other gas (potentially including air), such that specialty chemistry/catalyst is stripped of captured, reacted, and/or absorbed contaminate. In this step, another treatment can be deployed to capture the stripped components. Other regeneration methods could be utilized, as determined by the specific chemistries/catalyst/absorbents utilized.

[0052] It should be noted, that different chemistries, catalyst, or other media can be used, individually or in combination, as a part of this treatment approach as a either a pre-treatment stage, post-treatment stage. New specialty materials known as metal organic frameworks (MOFs), such as PCN-250 as developed by Texas A&M University and framergy Inc., can be used in this system and method as descried above. The MOFs can be used for bulk or selective treatment of contaminates, through absorption of said contaminates, and the regeneration step, as shown in FIG. 11, can be inclusive of such methods. However, the regeneration property and resulting stripped fluid could vary.

[0053] Turning now to FIG. 8, field trial results of the system and method of the present inventive concept are provided. Application parameters included a flow of 200-250 bbl/hr. Contaminates operable for processing via the system and method of the present inventive concept include carbon disulfide, dimethyl sulfide, diethyl sulfide, methyl ethyl sulfide, benzothiophene, DMDS, and/or carbonyl sulfide. Sulfur reduction ranges from 72 ppm to less than 5 ppm. Pressure is 75 psi. Initial temperature is greater than 200 F., and is cooled to below 140 F. It should be noted that through conventional laboratory testing methods, only an 15% approximate reduction sulfur was realized, whereas field testing utilizing the systems and methods described herein resulted in greater than 98% reduction (see FIG. 8).

[0054] The scalable nature of the system and method of the present inventive concept are capable of operating at flow rates over 10,000 bbl/hr, although typical production is about 250-1000 bbl/hr. A reduction target for total sulfur content may be selected to allow for the blending of fuels at less than 10 ppm total sulfur, in accordance with EPA Tier III fuel standards (or other commercial standards for non-vehicle fuels). The system design will be directly dependent on total sulfur and total production capacity (in bbl/day or scf/day or other similar measure) in the untreated fuel. It should be noted that the standards referenced may be different based on individual client requirements for specific commercial terms and/or regulatory standards.

[0055] It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that the present inventive concept disclosed herein is not limited to the particular embodiments disclosed, and is intended to cover modifications within the spirit and scope of the present inventive concept.

[0056] Turning now to FIG. 10, a schematic diagram is presented of the system 1000 having a first stage treatment contactor 1002 in a stacked configuration with a second-stage treatment contactor 1004, according to an illustrative embodiment. The first stage treatment contactor 1002 and the second stage treatment contactor 1004 are analogous to the vessel 100 described in relation to FIG. 1. The stack configuration allows the first- and second-stage treatment contactors 1002, 1004 to operate sequentially or in parallel.

[0057] It should be noted that, within each identified scrubber or treatment contactor, there would be a maintained liquid level of selective chemistries, at least covering the internal mixing/diffusion system, with untreated fuel being introduced into the treatment contactor through the mixing/diffusion system, for cylindrical type mixing/diffusion membrane, or from underneath the mixing/diffusion system for mixing/diffusion systems that utilize sheet or plate internal mixer/diffuser, where the fuel is treated after having passed through the internal mixing/diffusion system having contacted the specialty/targeted chemistries and then phase separating based on the specific gravity of the two different fluids, and finally being directed from an outlet of the scrubber unit(s) with the potential (particularly for liquid phases) to be initially directed into a final knockout pot or inlet of an additional scrubber unit, which isn't filled with liquid, to act as a final separation phase should any specialty/target chemistries flow through. In this final separation phase, the fuel would be further separated using specific gravity principles, whereby the treated liquid is removed through an outlet, while the specialty/target chemistry is removed from a separate outlet.

[0058] It should be noted, that each treatment contactor can, but may not have similar chemistries, absorbers or other media types. Non-limiting examples of the types of media that could be contained within the treatment contactor include commodity chemistries such as caustic, specialty scavengers such as Baker Hughes Exalt 1000 or 1100, solids medias such as activated carbon or ion exchange resins, or even different designed metal organic frameworks or similar non-metal structures.

[0059] It should further be noted, that the initial treatment contactor (primary), can have a selective chemistry used for converting hard to capture sulfur contaminates into easily reactive sulfur compounds, such as hydrogen sulfide (H.sub.2S), which then the secondary contactor can have commodity chemistries such as caustic, specialty scavengers, solids medias or even MOFs for the capture of H.sub.2S.
