Objectives

The overall aim of the project was to develop a novel integrated fuel gas cooler and sulphur and halide removal process for coal gasification plants. Specific objectives were:

  • To prove the concept of using a twin-bed reactor system is suited to this application.
  • To assess the performance of available sulphur sorbents in the twin-bed system.
  • To assess the effect of scale up on the performance of the system and the downstream effects on filter performance, residuecharacteristics and gas turbine performance.

Abstract This project was targeted at developing a novel integrated raw gas cooler and sulphur/halide removal process for gasification plants. This desulphurisation process is based on a twin fluidised bed system employing direct solids transfer between adjacent reactor vessels, with halide removal being achieved by means of sorbent injection.

Within this project a series of mathematical models were developed for the twin-bed desulphurisation concept. Then a 2-D cold model was designed and manufactured to demonstrate the concepts and the validity of the mathematical models produced.

Following on from this, a twin-bed unit was developed from initial design through construction to operation in the hot gas path of an air blown fluidised bed gasification pilot plant. Initially the unit was used as a 3-D cold model for further testing of the twin-bed concept and producing model validation data (particle and gas transfer rates between the twin-beds).
