Abstract
A system and method of producing syngas from a solid waste stream is provided. The system includes a low tar gasification generator that gasifies the solid waste stream to produce a first gas stream. A process module cools the first gas stream and removes contaminants, such as metals, sulfur and carbon dioxide from the first gas stream to produce a second gas stream having hydrogen. The second gas stream is received by a power module that generates electrical power from the second gas stream. The process module may include one or more heat exchangers.
Claims21
A system for converting solid waste material to energy comprising:
- an input module having a low tar gasification generator configured to produce a first gas stream in response to an input stream of solid waste material, the first gas stream including hydrogen;
- a process module fluidly coupled to receive the first gas stream, the process module including a first heat exchanger operable to cool the first gas stream, the process module further including at least one clean-up process module fluidly coupled to the first heat exchanger to receive the cooled first gas stream, the at least one clean-up process module configured to remove at least one contaminant from the first gas stream and produce a second gas stream containing hydrogen;
- and
- a hydrogen conversion device configured to receive the second gas stream and generate electrical power based at least in part from the hydrogen in the second gas stream.
A method of producing electrical power from a solid waste stream comprising:
- receiving the solid waste stream at a gasification generator;
- receiving an oxygen gas stream at the gasification generator;
- producing a first gas stream and residual materials using a gasifier;
- transferring the first gas stream to a first heat exchanger;
- decreasing the temperature of the first gas stream with the first heat exchanger;
- performing at least one clean-up process on the first gas stream to remove at least on contaminant;
- generating a second gas stream with the at least one clean-up process, the second gas stream including hydrogen;
- receiving the second gas stream with a hydrogen conversion device;
- and
- generating electrical power with the hydrogen conversion device based at least in part on receiving the second gas stream.
