Abstract
The present invention provides a gas conditioning system for processing an input gas from a low temperature gasification system to an output gas of desired characteristics. The system comprises a two-stage process, the first stage separating heavy metals and particulate matter in a dry phase, and the second stage including further processing steps of removing acid gases, and/or other contaminants. Optional processes include adjusting the humidity and temperature of the input gas as it passes through the gas conditioning system. The presence and sequence of processing steps is determined by the composition of the input gas, the desired composition of output gas for downstream applications, and by efficiency and waste minimization.
Claims14
A gas conditioning system for conditioning an input gas from one or more locations within a gasification system, the one or more locations including a gasifier, to provide a conditioned gas, said gas conditioning system comprising:
- a. a first gas conditioner comprising one or more particle removal units for removing particulate matter from the input gas received from the gasifier in a first conditioning stage to provide a conditioned gas and removed particulate matter;
- b. a solid residue conditioner, distinct from the gasifier, comprising a heat source and configured to receive, heat and process for receiving and processing said removed particulate matter to produce a secondary gas and solid waste;
- and
- c. a second gas conditioner operatively associated with said solid residue conditioner, said second gas conditioner comprising a gas cooler and one or more further particle removal units for removing particulate matter from said secondary gas to provide a partially conditioned secondary gas, said second gas conditioner configured to pass said secondary gas through said gas cooler for cooling prior to entry of the secondary gas into the one or more further particle removal units and to pass said partially conditioned secondary gas to the first gas conditioner for further processing.
