USE OF HYDRAULIC TURBOCHARGER FOR RECOVERING ENERGY FROM HIGH PRESSURE SOLVENTS IN GASIFICATION AND NATURAL GAS APPLICATIONS

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 energy is converted to electricity for use in powering parts of the process and system. This provides for a significant reduction in operating expenses.
