Abstract
As a part of systematization of absorption and refinery processing installation for coke oven gas, on-line analyzers for gas liquor treatment with activated sludge were developed and established. A T-NH{sub 3} analyzer using a potential difference titration method was equipped to control NH{sub 3} which had a bad influence upon activated sludge. The oxygen intake rate is measured with an activity measuring instrument in order to get the activity condition of bacteria. The SCN concentration of precipitator outlet solution is measured with an SCN(thiocyanogen) measuring instrument so that conditions of bacteria can be seized. An absorptiometry with ferric chloride is used to analyze it. For a COD measuring instrument, precipitator outlet solution is used and analysis with the JIS method is entirely automated. As a transparency measuring instrument, a color-difference colorimeter is used instead of the former instrument made of glass. According to the collected data, charged coal conditions, and operating conditions of coke oven, the process computer does the calculation for optimization and indicates operation control guidances to the operator. Automated on -line analyzers are useful to save a great deal of labor and contribute to the control and stabilization of operations. 9 figs., 1 tab.
