The processes for desulphurisation of coke oven gas can be subdivided into different methods:
• Dry oxidation processes
• Wet oxidation processes
• Absorption/stripping process
As first step this paper provides an overview of the most common desulphurisation processes and elaborates the differences in the case of the individual processes and process combinations as a function of the requirements to the gas purity and environmental protection. The overview offers a basis for concrete planning of the desulphurisation process.
As second step two common desulphurisation processes are compared in terms of technical process routes and Total Cost of Operation (TCO), i.e. capital and operational costs as well as revenues from saleable products.
