Abstract: The invention provides a process for separating monoethylene glycol from a mixture comprising monoethylene glycol and 1,2-butanediol, said process comprising the steps of: a. providing a first stream comprising monoethylene glycol and 1,2-butanediol to a first distillation zone operated at a first pressure and under conditions to remove a first bottoms stream comprising 1,2-butanediol and to remove a first azeotrope of monoethylene glycol and 1,2-butanediol from the first distillation zone as a first overheads stream; b. withdrawing said first overheads stream from said first distillation zone; and c. providing said first overheads stream to a second distillation zone operated at a second pressure higher than said first pressure and under conditions to remove a second bottoms stream comprising monoethylene glycol and providing a second azeotrope of monoethylene glycol and 1,2-butanediol as a second overheads stream; d. withdrawing said second overheads stream from the second distillation zone and providing it to the first distillation zone as at least a portion of the first stream comprising monoethylene glycol and 1,2-butanediol, e. wherein the mixture comprising monoethylene glycol and 1,2-butanediol is initially provided to at least one of the first distillation zone and the second distillation zone.

Abstract: A method for forming an insulated conductor heater with a final cross-sectional area includes reducing a cross-sectional area of an insulated conductor assembly to form an insulated conductor heater with a final cross-sectional area. The insulated conductor assembly may have been previously treated with at least one combination of a cold working step and a heat treating step. Reducing the cross-sectional area of the insulated conductor assembly to form the insulated conductor heater with the final cross-sectional area may include cold working the insulated conductor assembly to further reduce the cross-sectional area of the insulated conductor assembly by at most about 20% of the cross-sectional area of the insulated conductor assembly after the at least one combination of the cold working step and the heat treating step has been completed.

Abstract: The present disclosure generally relates to a system for injecting a fluid into a subsea hydrocarbon extraction component. The system comprises a pressure variance device including an ambient chamber and a variance chamber, the ambient chamber exposed to an external subsea environment and configured to transfer the pressure to the variance chamber via a pressure variance device piston. The system further comprises an accumulator including a fluid delivery chamber and a pressure chamber, the pressure chamber configured to receive the pressure from the variance chamber and transfer the pressure to the fluid delivery chamber via an accumulator piston. The system also comprises a control system configured to regulate injection of the fluid from the fluid delivery chamber into the hydrocarbon extraction component. In this way, the system can intensify or deintensify a hydrostatic pressure in the subsea environment to inject chemicals in the hydrocarbon extraction component at a desired pressure.

Abstract: An apparatus for controlling hydraulically actuatable components of a blowout preventer stack assembly and a system for same. The apparatus comprises a blowout preventer stack including hydraulically actuatable components and a lower marine riser package coupled to the blowout preventer stack and including additional hydraulic components. The lower marine riser package includes a solenoid valve configured to control at least some of the components. The solenoid valve receives hydraulic fluid from a dedicated accumulator or accumulator bank configured to supply hydraulic fluid exclusively for use with the solenoid valve. A closed-loop hydraulic circuit is formed between the accumulator or accumulator bank and the solenoid valve.

Abstract: The present disclosure generally relates to a system and method for installing a tubular element, such as a suction pile, in a bottom of a body of water. The system comprises a tubular element and a deintensifier in fluid communication with the tubular element. The deintensifier is configured to be exposed to an ambient pressure external to the tubular element and reduce pressure within the tubular element. The method comprises lowering the tubular element to the bottom of the body of water, filling the tubular element with water at ambient pressure, and exposing the water within the tubular element to a deintensified external ambient pressure so as to withdraw the water out of the tubular element.

Abstract: The invention relates to a device and method for distributing a liquid and gas in a multiple-bed downflow reactor, such as a hydrocarbon processing reactor, like a hydrocracker. The device comprises respectively the method uses a distributor device comprising a substantially horizontal collecting tray provided with a central gas passage. Gas passing in downward direction through the central gas passage is forced into a swirling motion by a swirler. This swirling motion has a swirl direction around a vertical swirl axis so that the gas leaves the central gas passage as a swirl. At a location above the collecting tray, a quench fluid is ejected into gas in an ejection direction, which is, viewed in a horizontal plane, at least partly opposite to the swirl direction.

Abstract: A mixture of hydrocarbons in vapour phase is passed through a feed scrubber. Feed scrubber vapour discharged from the feed scrubber is passed to a compression suction scrubber, and a vaporous compressor feed stream from the compression suction scrubber is compressed in a compressor train. A compressed vaporous discharge stream from the train of compressors is de-superheated, and at least a portion of the de-superheated stream is passed to a condenser, wherein this portion of the de-superheated stream is at least partly condensed to form a pressurized and at least partially condensed mixture of hydrocarbons. A recycle portion is split off from the de-superheated hydrocarbon stream, and a recycle flow is established to the compressor train of via a surge recycle separator drum and the compression suction scrubber. Liquid constituents removed and drained from the recycle portion in the surge recycle separator drum are fed to the feed scrubber.
