Abstract: A gas purification processing apparatus is described. The gas purification processing apparatus can control the generation of adsorption heat by an adsorbate substance in purification processing and thereby prevent desorption or ignition or the like of the adsorbate component by performing cooling processing on an adsorbent itself when needed.

During operation of the apparatus, gas is supplied from the source and purified by a purification part and then discharged as a purified gas. When the temperature of the purification part exceeds a predetermined temperature, a cooling medium is supplied from the cooling processing part to cool the purification part.

Abstract: A system and method captures and processes flare gas so that the gas is usable as compressed natural gas (“CNG”). The flare gas is pressurized by a combination of a booster compressor and a CNG compressor. While interstage and between the booster compressor and the CNG compressor, the gas is treated to remove moisture and to separate out higher molecular weight hydrocarbons. The moisture is removed by contacting the interstage gas with a hygroscopic agent within a dehydration unit. The moisture free hydrocarbon fluid is expanded, and/or externally cooled and directed to a knock out drum. Higher molecular weight hydrocarbons are separated from the fluid in the knock out drum. Gas from the knock out drum is compressed in the CNG compressor.

Abstract: A heat transfer fluid can be used as part of a multi-phase adsorption environment to allow for improved separations of gas components using a solid adsorbent. The heat transfer fluid can reduce or minimize the temperature increase of the solid adsorbent that occurs during an adsorption cycle. Reducing or minimizing such a temperature increase can enhance the working capacity for an adsorbent and/or enable the use of adsorbents that are not practical for commercial scale adsorption using conventional adsorption methods. The multi-phase adsorption environment can correspond to a trickle bed environment, a slurry environment, or another convenient environment where at least a partial liquid phase of a heat transfer fluid is present during gas adsorption by a solid adsorbent.
