A gas oil separation plant may include a gas compression plant, configured to receive, compress, and separate one or more feed streams and a warmed refrigerant stream into a compressed gas stream and a condensate stream, a flow system for dividing the condensate stream into an export condensate stream and a refrigerant stream, a gas dewpoint control plant comprising a gas chiller configured for indirectly contacting the compressed gas stream with the refrigerant stream, producing the warmed refrigerant stream, and a flow line for feeding the warmed refrigerant stream to the gas compression plant. A method for gas oil separation may include compressing and separating one or more feed streams and a warmed refrigerant stream into a compressed gas stream and a condensate stream. The condensate stream is divided into an export condensate stream and the refrigerant stream which chills the compressed gas stream and becomes the warmed refrigerant stream.

Integrated gas compression and refrigeration with internal cooling regeneration

Systems and methods of integrated gas oil separation are disclosed. Systems include a high pressure production trap (HPPT), a low pressure production trap (LPPT), a low pressure degassing tank (LPDT), a first knockout drum (KOD) fluidly coupled to the LPDT and operable to accept an atmospheric pressure off-gas from the LPDT, an atmospheric pressure compressor fluidly coupled to the first KOD and operable to compress the atmospheric pressure off-gas to introduce the atmospheric pressure off-gas from the LPDT into the LPPT inlet feed stream, a second KOD fluidly coupled to the LPPT and operable to accept a low pressure off-gas from the LPPT, and a low pressure compressor fluidly coupled to the second KOD and operable to compress the low pressure off-gas to introduce the low pressure off-gas from the LPPT into the crude oil inlet feed stream.

Integrated gas oil separation plant for crude oil and natural gas processing

A system and method for recycling flare gas back to a processing facility that selectively employs different numbers of ejector legs depending on the flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Valves are disposed in piping upstream of the flare gas and motive fluid inlets on the ejectors, and that are selectively opened or closed to allow flow through the ejectors. The flowrate of the flare gas is monitored and distributed to a controller, which is programmed to calculate the required number of ejector legs to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves, which open or close the valves to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas.

Dynamic multi-legs ejector for use in emergency flare gas recovery system

A system and method for dispensing an injection material to an injection point. The injection material is stored in a tank and disposed to parallel piped vessels. An orifice is disposed in piping connected to discharge ends of the vessels, and has an opening with a designated cross sectional area. A high pressure fluid drives the injection material to the injection point; the pressure of the high pressure fluid is regulated with a pressure control valve. Valves in the inlet and discharge piping connected to the vessels are selectively opened and closed so that injection material flows to and from the vessels. Vessels vent to a recycle/recovery system to reduce vessel pressure enabling refilling with injection material. Valves in the pressurizing and depressurizing lines are selectively opened and closed to depressurize and refill the vessels to have continuous chemical injection to the injection location.
