An Overview of Coal based Integrated Gasification Combined Cycle …
1.3 IGCC process description. Figure 1 shows the main blocks of a coal based IGCC plant similar to the recent demonstration units. The coal is supplied to the gasifier where it is partially oxidized under pressure (30-80 bar). The plant uses oxygen as oxidant and therefore has an air separation unit (ASU).
The coal sector in Australia is not a homogenous sector, with coal-red electricity generation, coal mining (thermal and metallurgical), and coal transport and logistics all facing dierent challenges. This report considered the socio-economic characteristics of two key coal regions, the Latrobe Valley
