Abstract: A method for recovering methane gas from a landfill involves the use of a main absorber, a flash system, an optional ancillary absorber and an optional polishing absorber. The recovered gas is maintained at a temperature that enhances a solvent's ability to absorb carbon dioxide from the recovered gas. While the main absorber uses the solvent for absorbing most of the carbon dioxide from the recovered gas, the flash system removes much of the carbon dioxide from the solvent exiting the main absorber. In some examples, at least portion of the flash system operates at subatmospheric pressure to create a vacuum that draws in a generally inert stripper gas (e.g., air, nitrogen, etc.) at atmospheric pressure. The stripper gas helps remove carbon dioxide from the solvent in the flash system.

Abstract: In a method for recovering volatile components from a solid material, a liquid phase is mechanically removed from the solid material. Subsequently, the solid material is dried by exposing the solid material to superheated steam circulating in a closed circuit. From the closed circuit excess steam that contains volatile components given off by the solid material is removed. The volatile components are separated from the excess steam by condensing the excess steam to a condensed phase and the volatile components are from the condensed phase by adding suitable ions to the condensed phase to crystallize the volatile components.

Abstract: A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. The compact and portable liquid concentrator is mountable on a truck bed or skid for easy transportation to remote sites.
