摘要： The present process comprises a means for energy savings in one or more process pumps by driving the one or more pumps with a variable-speed driving means. The invention is particularly useful in the separation of an adsorbed product from a mixture of components using simulated-moving-bed adsorption associated with a large circulating stream pumped with variable-speed driving means for conservation of energy relative to the known art. The improvement is particularly applicable to a process for the separation of para-xylene from mixed C8 aromatics.

摘要： The invention provides a process and system for regenerating a solvent used to remove carbon dioxide from feed gases, such as natural gas and synthesis gas. The process and system employs an eductor or ejector as an alternative to the prior art's vacuum compressor that is placed on the vapor stream from a vapor flash. This process and system saves substantial capital and operating costs over the prior art.

摘要： The invention provides a process and system for regenerating a solvent used to remove carbon dioxide from feed gases, such as natural gas and synthesis gas. The invention employs one or more hydraulic turbochargers to transfer energy from a higher energy solvent stream to a lower energy solvent stream. This provides for a significant reduction in operating expenses.
