摘要： A process is described for removing heavies and lights from a hydrocarbon-rich feed fraction. A heavies-rich liquid is rectificatorily removed (1st removal stage) from a partially condensed feed fraction. Heavies-depleted gas is partially condensed and rectificatorily separated into a methane-rich liquid fraction and a lights-rich gas fraction (2nd removal stage). The 1st removal stage is operated at a pressure of at least 25 bar. The heavies-depleted gas fraction does not undergo pressure elevation before being fed into the 2nd removal stage. Reflux for the 2nd removal stage is produced via an open loop refrigeration cycle. Refrigerant circulating in the open loop refrigeration cycle is vaporized to two different temperature levels against the reflux streams in a head condenser and a side condenser of the 2nd removal stage. The pressure of refrigerant vaporized in the side condenser is at least three times the pressure of refrigerant vaporized in the head condenser.

摘要： The present invention relates to methods and apparatuses for the operation of a distillation tower containing a controlled freezing zone and at least one distillation section. The process and tower design are utilized for the additional recovery of hydrocarbons from an acid gas. In this process, a separation process is utilized in which a multi-component feedstream is introduced into an apparatus that operates under solids forming conditions for at least one of the feedstream components. The freezable component, although typically CO2, H2S, or another acid gas, can be any component that has the potential for forming solids in the separation system. A dividing wall is added to at least a portion of the lower distillation section of the apparatus to effect the separation of at least some fraction of the hydrocarbons in that portion of the tower.

摘要： A process for recovering CO.sub.2 from a mixture of light hydrocarbons, e.g. light hydrocarbons produced from a CO.sub.2 injection enhanced oil recovery. The mixture is distilled in a distributive zone with CO.sub.2 produced overhead and in the bottoms. The overhead and bottoms produced from the distributive zone are then fed to first and second concentrating distillation zones, respectively. The first concentrating zone produces a bottoms product rich in CO.sub.2 and an overhead product rich in methane and lean in CO.sub.2. The second concentrating zone is refluxed with lean oil and produces a CO.sub.2 distillate and a CO.sub.2 -lean bottoms product. In various embodiments, at least a section of each of the concentrating zones are placed in a single column, the CO.sub.2 product streams are taken as a side draw, vapor from the first concentrating zone is used in an open cycle heat pump to heat the second concentrating zone, the distributive zone is thermally coupled with one or both of the concentrating zones, and the distributive zone and certain sections of the concentrating zones are physically integrated into a single column.

摘要： Oxygen-containing gas comprising no more than about 50 mol % oxygen is fed (150) to an auxiliary separation column (40) in a multiple column cryogenic air distillation system comprising at least a higher pressure (“HP”) column (10) and a lower pressure (“LP”) column (30) for separation into nitrogen-rich overhead vapor and oxygen-rich liquid. Oxygen-rich liquid is fed (154) from the auxiliary column (40) to an intermediate location in the LP column (30). The auxiliary column (40) is refluxed with a liquid stream from or derived from the HP column (10). One advantage of the invention is that the diameter of the upper sections (II, III) of the LP column (30) need no longer be larger than the diameter of the rest of the column system thereby increasing the capacity of the column system (under the constraint of a defined maximum column section diameter).
