Abstract: Processes and units are described for recovering energy from a waste gas capture system. Heat energy generated from the compression of waste gas can be integrated with a waste gas capture system to reduce energy needs of the system. Recovered heat energy is used to produce useful energy sources such as low pressure steam that can be integrated back into the waste gas capture system. The recovered heat energy can be used to produce the waste gas, for instance in a regeneration column and reboiler. The produced waste gas can be fed into the compression units designed to transform the waste gas into a storage fluid.

Abstract: An illustrative embodiment of the invention provides an electromagnetic filter for fluids in which two magnetizable beds are longitudinally separated. Each of these beds is provided with its own respective magnetizing coil. Incoming fluid is admitted to the space between the magnetizable beds. This flow is divided into two longitudinal oppositely directed streams in order to enable each stream to pass through its respective bed.
