Generic line-up with OLGA
The success of a biomass gasification system is highly influenced by the logical line-up of the gas treatment steps.
- Gas cooling
- Removal of solid particles
- Removal of organic impurities (tar)
- Condensation of water
- Removal of inorganic impurities
- Gas compression
This logical order is depending on the choice of the tar removal system. To introduce you to the OLGA technology it is important to first describe its position in a generic line-up of an integrated air blown gasification system with gas engine for combined heat & power (CHP) production:
It is very important to consider the logical order of the gas cleaning steps. In principle mixing of dust, tar and water must be avoided. It is best to separate the solids first. As much solids as practically possible should be removed at a temperature in which water and tars are not present (> 400 °C). After that tars have to be removed above the water dew point to a level at which the tar problem can not occur in downstream equipment. After OLGA inorganic impurities can easily be removed with aqueous scrubbers, tar is not a problem anymore for operation of these scrubbers and does not contaminate the scrubber water.
