    摘要: The invention relates to a system, method and apparatus for removing heavies from natural gas. Natural gas and an external rich reflux gas feed are processed in a single column refluxed absorber. A bottoms stream is routed to a first heat exchanger and then to a stabilizer column where an overhead stream from the stabilizer column is routed through a condenser for partial separation into an overhead stream. A rich solvent may be introduced to the stabilizer column. The overhead stream is routed through a condenser for partial separation into a stabilizer reflux and a second overhead stream lights. The second overhead stream lights is routed to a heat exchanger and then routed to a partial condenser where the stream is separated into a heavies rich reflux stream, a distillate stream and heavies treated natural gas stream. The rich reflux is routed through a heat exchanger and the rich reflux is pumped to the single column refluxed absorber to be introduced into the single column refluxed absorber as the external rich reflux gas feed.

    摘要: A process for recovering liquefied petroleum gas from tail gas includes recovering a tail gas stream from a pressure swing adsorption zone and contacting the tail gas stream with a sponge liquid such as an unstabilized reformate liquid stream in order to recover C3+ hydrocarbons from the tail gas stream. The C3+ hydrocarbons may be recovered from the sponge liquid as liquefied petroleum gas.

    摘要: The invention relates to a method for recovering absorbed hydrocarbon components while absorbing acid gases from technical gases, as for example a natural gas, by means of physically active absorption agents, wherein the inventive method consists in increasing the pressure of a loaded absorption agent extracted from an adsorption device, in adding said loaded absorption agent to the top of a rectification column which consist of a lower feeding stove and of one or several lateral stoves operating at a pressure slightly greater than the absorption column pressure, in adjusting an equilibrium is said rectification column in such a way that the acid gas concentration in the absorbent agent increases in the direction away from the bottom of the column and the hydrocarbon concentration decreases in said direction, in extracting a heated hydrocarbon-poor and acid gas component-rich absorption agent from the bottom of the column and in transferring said agent to an acid gas desorption device, in extracting a hydrocarbon-poor and acid gas component-rich recycling gas from the top of the rectification column, in cooling said recycling gas in a recycling gas cooler to a temperature of a service gas directed in the absorption device and in transferring said recycling gas directly to the absorption device or in mixing it with the service gas.

    摘要: A process for extracting natural gas liquids (NGLs) from natural gas that involves contacting natural gas from one source with crude, or heavy, oil from a different source under conditions that promote enrichment of the crude or heavy oil with NGLs from the natural gas. Apart from functioning as an absorbent fluid, the crude or heavy oil also functions as the carrier medium for the absorbed NGLs. When practicing the process, unlike conventional methods, there is no need to regenerate the absorbent fluid, in this case the crude and heavy oil, for recycling.

    摘要: A process for the recovery of gaseous products from the product mixture obtained by contacting a hydrocarbon feed with a catalyst in a fluid catalytic cracking process, wherein the liquid, obtained by separating the top product of main fractionators into gaseous and liquid fraction, when supplied to the absorber has a temperature of between about 8–25 DEG C. This liquid may be pre-saturated with gaseous top product from absorber; or also a high boiling fraction (cat cracker naphtha/light cycle oil) may be first separated from this liquid by distillation.
