摘要： Dans un procédé de séparation d'un gaz d'alimentation contenant au moins 87 % mol CO2 et entre 5 et 11 % mol de méthane pour produire du CO2 liquide épuré en méthane, un débit gazeux (1) du gaz est envoyé réchauffer le liquide de cuve d'une colonne de distillation (5) par échange de chaleur indirect dans un bouilleur (13), le liquide de cuve étant vaporisé (3) dans le bouilleur et envoyé en cuve de la colonne et le débit gazeux étant refroidi tout en restant gazeux, le débit gazeux refroidi est mélangé avec un gaz de tête (7) provenant de la tête de la colonne pour former un mélange gazeux (15) et le mélange gazeux est refroidi jusqu'à une température égale ou inférieure à -35°C au moyen d'un cycle fermé de réfrigération (19, 23) afin de condenser partiellement le mélange gazeux formant un liquide (27) enrichi en CO2 et appauvri en méthane par rapport au mélange envoyé au condenseur, le liquide enrichi en CO2 est envoyé en tête de la colonne pour constituer un liquide de reflux, un liquide (9) contenant au moins 99 % mol, de CO2 est soutiré en cuve de la colonne comme produit final.

摘要： Nitrogen is removed from a liquefied natural gas feed (41) by a two stage separation in which the liquefied natural gas (41) is first fractionated (23) to provide a first nitrogen-enriched overhead vapour stream (46) and a nitrogen-containing bottoms liquid stream (19) and then at least a portion of said bottoms liquid stream (19) is fractionated (25) to provide a second nitrogen-enriched overhead vapour stream (36) that is of lower purity than said first overhead vapour stream (46) and a purified liquefied natural gas stream (50). Preferably, the first fractionation is conducted in a distillation column (23) refluxed (45) with nitrogen overhead (43) condensed in a condenser (24) located in a flash drum (25) in which the second fractionation is conducted. The provision of two nitrogen-containing streams (26, 36) of different concentration permits control of the nitrogen content of fuel gas for use in the natural gas liquefaction plant.

摘要： Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to remove contaminants, such as water, from the stream. As part of the process, the adsorbent bed unit is purged with a purge stream that is provided from the overhead of the demethanizer. The configuration integrates a PPSA dehydration system with a cryogenic recovery system.

摘要： A system includes a waste heat recovery heat exchanger configured to heat a heating fluid stream by exchange with a heat source in a crude oil associated gas processing plant; and a modified Goswami energy conversion system. The modified Goswami energy conversion system includes a first group of heat exchangers configured to heat a first portion of a working fluid by exchange with the heated heating fluid stream; and a second group of heat exchangers configured to heat a second portion of the working fluid. The modified Goswami energy conversion system includes a rectifier configured to receive the heated first and second portions of the working fluid and a third portion of the working fluid and to output an overhead discharge stream and a liquid stream, the third portion of the working fluid being at a lower temperature than the heated first and second portions of the working fluid. The modified Goswami energy conversion system includes a cooling subsystem including one or more cooling elements configured to cool a chilling fluid stream by exchange with the overhead discharge stream; and a turbine configured to generate power from the liquid stream of the working fluid.

摘要： A process is described herein for removing high freeze point hydrocarbons, including benzene compounds, from a mixed feed gas stream. The process involves cooling process streams in one or more heat exchangers and separating condensed compounds in multiple separators to form a methane-rich product gas stream. Select solvent streams from a fractionation train and/or separate solvent streams are employed to lower the freeze point of one or more streams that contain high freeze point hydrocarbons. A corresponding system also is disclosed.
