摘要： A gas plant using an Ortloff or similar process comprising the use of a second expander in place of a valve used in most demethanizer reflux systems, wherein a compressor wheel is used to increase the pressure of the partial stream of inlet gas that is used to provide heat to the demethanizer reboilers. This stream remains a separate stream and is used for the flow of gas that feeds the demethanizer reflux expander.

摘要： A method for separating a vapor from a carrier gas is disclosed. A hydrocyclone is provided with one or more nozzles on the wall of the hydrocyclone. A cryogenic liquid is provided to the tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the hydrocyclone. The carrier gas is injected into the hydrocyclone through the one or more nozzles. The vapor dissolves, condenses, desublimates, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted gas is drawn through the vortex finder while the vapor-enriched cryogenic liquid is drawn through the apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.

摘要： Systems and methods are provided for recovering helium from a feed comprising helium, carbon dioxide, and at least one of nitrogen and methane. The feed is separated in a first separator to form helium-enriched stream and a CO2-enriched stream. The helium-enriched stream is separated in a pressure swing adsorption unit to form a helium-rich product stream and a helium-lean stream. At least a portion of the helium-lean stream is recycled to the first separator with the feed. In some embodiments, a membrane separation unit is used to enhance helium recovery.

摘要： Methods and systems for dynamically planning a well site are provided herein. Methods include flowing a raw gas stream though a suction scrubber to form a feed gas stream and compressing the feed gas stream to form a compressed gas stream. Methods include cooling the compressed gas stream in a cooler to produce a cooled gas stream. Methods include feeding the cooled gas stream into a gas treatment system, using a turboexpander, to produce a conditioned gas and a waste stream. Methods include heating the conditioned gas in a heat exchanger, where the conditioned gas is a superheated, sweetened, gas. Methods also include burning the conditioned gas in a turbine generator and mixing the waste stream into the raw gas stream upstream of the suction scrubber.

摘要： An apparatus and method for flow management and CO2-recovery from a CO2 containing hydrocarbon flow stream, such as a post CO2-stimulation flowback stream. The apparatus including a flow control zone, a gas separation zone, a pretreatment zone, and a CO2-capture zone. The CO2-capture zone is in fluid communication with the pretreatment zone to provide CO2-capture from a pretreated flowback gas stream and output a captured CO2-flow stream. The CO2-capture zone includes a flow splitter to direct a first portion of the pretreated flowback gas stream to a CO2-enricher to provide an enriched CO2-stream for mixing with a second portion of the pretreated flowback gas to form a mixed stream. The CO2-capture zone further includes at least one condenser to output the captured CO2-flow stream.

摘要： The present disclosure provides a method for separating a feed stream in a distillation tower. The method may include forming solids in a controlled freeze zone section of the distillation tower; emitting radiation from a first radiation source in the controlled freeze zone section while the controlled freeze zone section forms no solids; detecting radiation emitted by the first radiation source as a first radiation level; detecting radiation emitted by the first radiation source as a second radiation level after detecting the first radiation level; and determining whether the solids adhered to at least one of on and around a first mechanical component included in the controlled freeze zone section based on the first radiation level and the second radiation level.
