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 system may include an output manifold that may be in fluid communication with a reservoir and that may include multiple discharge ports. Each of the discharge ports may be configured to discharge electrorheological fluid into a housing. A recovery manifold may be in fluid communication with the reservoir and include multiple recovery ports. Each of the recovery ports may be configured to receive the electrorheological fluid from a housing. A gas remover may be positioned to extract gas from the electrorheological fluid received from the recovery ports. A housing may be connected to the system, and electrorheological fluid from the system may be pumped through the housing and the gas remover.

A vapor recovery apparatus degasses oil and water produced by an oil well. The apparatus has a first vessel forming a column. Oil containing gas enters the bottom of the first vessel and flows up to a liquid outlet. Heat applied to the rising oil, wherein the oil foams. Gas escapes into the upper end. The foam flows into a second column and along a roughened surface. The bubbles in the foam break apart releasing the gas. The oil flows down the second column to an outlet. Water is introduced into a third vessel. The water releases gas therein, which gas mingles with the gas from the oil. The third vessel is located around the first and second vessels. A compressor may be used to withdraw the gas and provide hot compressed gas to heat the rising oil in the first column.

A separator system and method may provide a four-way separator that may separate a material and remove a hazardous material. The hazardous material may include gas and sand that may be removed by the four-way separator. The separator system and method may further provide a main unit that may include three chambers or recirculation hoppers, an auger sand extractor, and a strap tank. The separator system and method may provide a faster rig-up time and may be exclusively driven by hydraulics.

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.

The purging manifold includes a second reservoir. The purging manifold further includes a supply port; a fluid inlet port; and a purging outlet port. The purging outlet port is disposed above the supply port to convey fluid to the first reservoir. The printing system also includes a fluid interface connector to fluidically connect to the supply port and fluidically connect to the fluid ejection device.

Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. In particular, 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.
