Abstract
A method of removing impurities from a gas including the steps of removing impurities from biogas comprising at least one adsorbents via a process vessel or reactor, directing the purified gas to an device to generate power and/or heat, regenerating the saturated adsorption media with the waste heat recovered from the engine exhaust and directing the regeneration gas (hot air or engine exhaust) to flare, engine exhaust stack, or atmosphere.
Claims23
A method of removing emissions from a regeneration air comprising the steps of:
- receiving fuel comprising at least one hydrocarbon in a first system line;
- directing the fuel to a first reactor containing an adsorption media;
- desorbing an impurity from the fuel;
- directing the fuel to an engine;
- generating an engine exhaust;
- directing the engine exhaust to a conditioning unit;
- injecting an air source into a second system line;
- directing the air source to a heating component;
- directing the heated air source to a second reactor;
- generating regeneration air in the second reactor;
- injecting the regeneration air into the first system line downstream of the conditioning unit;
- mixing the regeneration air with the engine exhaust;
- and
- directing the mixture of the regeneration air and engine exhaust to an outlet.

A device comprising:
- a split line to separate a first system line from a second system line;
- an inlet for receiving fuel comprising at least one hydrocarbon in the first system line;
- a first reactor in the first system line containing an adsorption media to receive the fuel;
- an engine in the first system line to receive the fuel from the first reactor;
- a conditioning unit in the first system line to receive the engine exhaust from the engine;
- a first injector to inject an air source into the second system line;
- a heating component in the second system line to heat the air source;
- a second reactor to receive the air source from the heating component and generate a regeneration air;
- a second injector to inject the regeneration air into the first system line downstream of the conditioning unit;
- and
- an outlet to direct the regeneration air and engine exhaust out of the first system line.
