Thylox Process and Its Technical and Economical Results

摘要

The technical development of the Thylox process which operates as a one-stage process with clear solutions to recover elementary sulphur and its expansion to 21 plants with an annual output of almost 3.4 billion m exp 3 of gas are described. Furthermore, two Japanses Thylox plants are described and their results are reported. The economics of the Thylox process are discussed on the basis of the results obtained up to now, and the operating costs are represented graphically as a function of the hydrogen sulphide content and the output of the plant for coke-oven gas as well as for water gas. In the purification of cokeoven gas under certain circumstances even a profit may result in the case of large gas outputs. Thanks to its economic and operational advantages and the substantial removal of the hydrogen sulphide the Thylox process should find application in the furture in Germany too for the purification of water gas or synthetic gas.
