Abstract
A temperature swing adsorption process to purify a gas comprising at least one adsorption step and at least one regeneration step wherein the regeneration step takes place at a lower pressure than the adsorption step. The pressure is increased by a repressurization step between the regeneration step and the adsorption step, and then a purge step takes place after said repressurization step.
Claims7
A temperature swing adsorption process to purify a gas comprising at least one adsorption step and at least one regeneration step wherein said regeneration step takes place at a lower pressure than said adsorption step and wherein pressure is increased by a repressurization step between said regeneration step and said adsorption step, wherein a purge step takes place after said repressurization step;
- wherein said purge step reduces compositional, pressure and temperature fluctuations compared to a temperature swing adsorption system operating without said purge step;
- wherein the purge step is executed with a feed gas supplied through repressurization valves.
