摘要： A process for separation of a high pressure gas stream (10) such as light refinery gases in which the gas mixture is expanded, preferably through a turbine (28), and separated into first vapor and liquid portions. The first vapor portion (31) may be recovered as, for example, methane-rich product gas. The first liquid portion (33) is raised to an intermediate pressure, revaporized, and introduced to a fractionator (36) from which an ethane-containing stream is recovered. The ethane-containing stream (37) is then cooled and separated (in 39) into a second vapor portion (40) and a second liquid portion (42) which is then expanded (in 43) and combined with the expanded starting gas mixture (29) to increase the amount of refrigeration that may be recovered from the first liquid stream prior to its fractionation.

摘要： A method for sub-cooling normally gaseous hydrocarbon mixtures produced in a cryogenic process unit wherein the mixture (1) is introduced to a gas/liquid separator (4), which may be a storage vessel, and vapor (8) containing at least two components of the mixture is recovered as refrigerant, employed in an open cycle refrigeration system to sub-cool the hydrocarbon mixture, and returned to the separator. The system is particularly useful for sub-cooling a hydrocarbon product stream while, at the same time, recovering boil-off vapor from a cryogenic storage vessel.

摘要： A process for separating gaseous or liquid hydrocarbons in first and second fractionation zones wherein the first fractionation zone (36) employs a side reboiler (45) discharging below the side draw point. A vapor sidestream (47) is removed from the first fractionator (36) below the side draw point and introduced to the second fractionator (48). The flow scheme permits control of the first fractionator bottoms temperature to match available low level waste heat which may therefore be used in fractionator reboiling duty.

摘要： A process for separation of a high pressure gas stream such as refinery gas in which the starting gas mixture (1) is cooled and separated (in 4) into a first vapor portion (5) and a first liquid portion (6) which is expanded to an intermediate pressure. The first vapor portion (5) is further cooled and separated into a second vapor portion (10) which may be further processed for ultimate recovery of, for example, a methane-rich product gas and a second liquid portion (11) which is expanded (in 12) to essentially the same intermediate pressure and combined with the expanded first liquid portion (16). The resulting mixed intermediate pressure stream (17) or a portion thereof is then employed as refrigerant.

摘要： A method for sub-cooling normally gaseous hydrocarbon mixtures produced in a cryogenic process unit wherein the mixture (1) is introduced to a gas/liquid separator (4), which may be a storage vessel, and vapor (8) containing at least two components of the mixture is recovered as refrigerant, employed in an open cycle refrigeration system to sub-cool the hydrocarbon mixture, and returned to the separator. The system is particularly useful for sub-cooling a hydrocarbon product stream while, at the same time, recovering boil-off vapor from a cryogenic storage vessel.
