Dissolution of sediments and deposits in Coke-Oven-Gas purification

Abstract

The report focuses on the development and operational testing of an organic agent for the chemical dissolution of organic sediments in technological units of a wet ammonia system for coke-oven-gas purification – a stripping column of free and bound ammonia and a hydrogen-sulphide scrubber. The experience gained has been used in the reorganisation and subsequent long-term implementation of the desulphurisation process of raw coke-oven gas in the coking plant ArcelorMittal a.s. Ostrava.
