Abstract
An integrated biomass conversion system and a method of starting and shutting down the system are disclosed. The integrated biomass conversion system comprises a syngas generator, such as a gasifier, a cleanup engine and a syngas utilization system, which could be a power producing engine or a chemical reactor for chemical or fuel synthesis. The cleanup engine operates rich and at high temperatures so that the tars exhausted by the syngas generators are destroyed and not allowed to foul other components. An orderly sequence to start and shut down the integrated biomass conversion system is disclosed.
Claims36
An integrated biomass conversion system for producing power from solid fuels, comprising:
- a syngas generator to form producer gas from solid fuels;
- a cleanup engine in communication with an outlet of the syngas generator to remove tar from the producer gas and create cleaned syngas;
- a power producing engine in communication with an outlet of the cleanup engine to generate power;
- a generator flare;
- a syngas flare actuator, in communication with the outlet of the syngas generator and the generator flare;
- a cleanup flare;
- a cleanup flare actuator, in communication with the outlet of the cleanup engine and the cleanup flare;
- a power engine fuel actuator disposed between the outlet from the cleanup engine and an inlet of the power producing engine;
- a cleanup air filter;
- a cleanup air actuator in communication with the cleanup air filter and an inlet of the cleanup engine;
- a power engine air filter;
- and
- a power engine air actuator in communication with the power engine air filter and the inlet of the power producing engine.
An integrated biomass conversion system for producing chemicals from solid fuels, comprising:
- a syngas generator to form producer gas from solid fuels;
- a cleanup engine in communication with an outlet of the syngas generator to remove tar from the producer gas and create cleaned syngas;
- a chemical reactor in communication with an outlet of the cleanup engine;
- a generator flare;
- a syngas flare actuator, in communication with the outlet of the syngas generator and the generator flare;
- a cleanup flare;
- a cleanup flare actuator, in communication with the outlet of the cleanup engine and the cleanup flare;
- a chemical reactor actuator disposed between the outlet from the cleanup engine and an inlet of a chemical system.
