The development and implementation of continuous and automated measurement of total sulphur, NH(3) and naphthalene of purified coke oven gas
The main objective of the coke oven by-product plant at Hoogovens has changed over the past twenty years from producing "by-products" to cleaning the crude coke oven gas. Ammonia, naphthalene and sulphur are partly removed from the oven gas in order to prevent difficulties with corrosion and plugging of the pipes (through which the cleaned gas is pumped to the users) and to reduce the emission of sulphur oxides. The project aimed at providing instruments for the continuous measurement of the total sulphur, ammonia and naphthalene concentrations in coke gas, which are reliable and maintainable under coke plant conditions. The results have enabled Hoogovens to operate two total sulphur measurement installations from January 1988 onwards. The work on NH(3) and naphthalene has resulted in measurement installations that have been kept in continuous operation for 5 and 8 weeks respectively, without any problems. The equipment for NH(3) measurement is suitable for industrial use. For naphthalene, however, redesign of the equipment is necessary to make it less maintenance-intensive.
