One method disclosed herein of processing a process fluid that comprises dissolved gas includes performing a degassing process on the process fluid by heating the process fluid via heat transfer with a heat transfer fluid, wherein at least some amount of the heat transfer fluid condenses in the first heat transfer process and latent heat of the heat transfer fluid as it condenses is used to increase the temperature of the process fluid. Thereafter, the heat transfer fluid is passed through an expansion device so as to produce a post-expansion heat transfer fluid. The temperature of the heated process fluid is decreased by performing a second heat transfer process between the post-expansion heat transfer fluid and the heated process fluid, wherein the temperature of the post-expansion heat transfer fluid is increased and the latent heat that was supplied to the process fluid in the first heat transfer process is removed.

Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

A method and system for measuring an amount of a gas dissolved in a liquid is described, in which the liquid is transferred to an equilibrator and in which the amount of the various gases is measured in the gas phase of the equilibrator and that a calculation of the amount of gas which is dissolved in the liquid is carried out.

A system for conditioning live crude oil to produce stabilized oil that can be stored in a conventional oil storage tank and hydrocarbon gas includes a stabilizer tower and a heater treater. The stabilizer tower receives oil from separators at the wellhead production facility and outputs oil to the heater treater. The heater treater outputs gas back into the stabilizer tower and, optionally, recycles a portion of oil output back into the heater treater, which enhances oil output.

A system includes a purification unit configured to process a vapor stream including sulfur dioxide. The purification unit includes an inlet configured to allow the vapor stream to enter the purification unit. The purification unit includes a steam coil configured to circulate steam and provide a source of heat. The purification unit includes a packed bed. The purification unit includes a tray configured to accumulate sulfur. The purification unit includes an absorber section configured to remove at least a portion of the sulfur dioxide from the vapor stream. The purification unit includes an outlet configured to allow an effluent with a lower sulfur dioxide content than the vapor stream to exit the purification unit. The system includes a sulfur tank including a vent line in fluid communication with the inlet. The vent line is configured to allow vapor to flow from the sulfur tank to the purification unit.

The pump according to the present disclosure includes: a housing having a suction chamber and a discharge chamber formed therein; a suction part extending outwardly from a circumferential surface of the housing, and having a suction passage formed therein through which a fluid is introduced into the suction chamber; a discharge part disposed under the suction part, extending from the circumferential surface of the housing in a direction opposite to the suction part, and having a discharge passage formed therein through which the fluid is discharged from the discharge chamber; a partition wall dividing the suction chamber and the discharge chamber, and having a communication hole formed at a center thereof for allowing the suction chamber to communicate with the discharge chamber; an impact body disposed toward the suction part so as to come into contact with the fluid introduced into the suction chamber through the suction passage; and a gas discharge part disposed at an upper portion of the circumferential surface of the housing and communicating with an outside so that gas, separated from the fluid in contact with the impact body, is discharged, wherein the suction part extends in one direction perpendicular to a virtual center line passing through the housing, and the impact body is disposed in a direction opposite to an extending direction of the suction part with respect to the virtual center line.

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first three-phase gas separation. The gas stream separated out is cooled with the resulting hydrocarbon condensates reintroduced to the stream of hydrocarbon-liquid phase that was separated from the fluid. The resulting combined stream can be cooled or heated as necessary.

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first gas separation followed by pressure reduction and then a second gas separation. Indirect follows the second gas separation and then three-phase separation.

A filtration system for downstream processing of a suspension containing a labile solid material in a liquid medium, wherein dissolved gas in liquid environment is controlled to ensure optimal process conditions. The dissolved gas can be controlled by a gas-liquid interface by bubbling; a liquid-liquid interphase transfer process using a gas vector substance; a liquid-solid interphase transfer process using a gas permeable solid or a reaction evolving oxygen or other gas/gases. The retained solid material is removed in batch operations, continuous operations or mixed-type operations. The process can also include further filtration, heat-treatment, and removal of at least a part of the liquid. The filtration system could also process a concentrated suspension which is devoid of the free liquid, then heat-treated and the liquid produced by the treatment removed by further filtration. The solid material can be a biomass.

A passive phase separator includes an input conduit including an inlet through which multi-phase flow enters the input conduit and a gas conduit formed at an angle from the input conduit. A liquid removal chamber is formed in line with the input conduit. The gas conduit is closer to the inlet than the liquid removal chamber. The liquid removal chamber holds liquid from the multi-phase flow, and the gas conduit carries gas from the multi-phase flow.
