Options for covered coal storage are analyzed, with attention to technological and environmental considerations.
For timely determination of the ash composition in coal, chemical analysis has been replaced by X-ray analysis using a Spectroscan MAX-GV spectrometer at OAO Koks. That permits prompt determination of the ash basicity, which affects the reactivity and hot strength of the coke. The plant’s coal...
Joint research by OAO Koks and the Kuznetsk Center of OAO VUKhIN on coke production and the creation of special carbon materials is reviewed.
Experience with a coke battery containing coke ovens (height 6.7 m) with lateral supply of heating gas is outlined. Means of eliminating the deficiencies discovered in debugging the coke battery are discussed.
Operational experience with a system for dust-free coke discharge is outlined.
Means of increasing the productivity and reducing emissions in the reconstruction of CDQ systems are considered.
Operational experience with rubber screens in coke sorting is considered.
The removal of tar and suspended particulates from phosphate solutions at a quartz filter is considered. The filter’s optimal operating conditions are determined. Introduction of this filter reduces the downtime in the circulating phosphate system for the removal of tar deposits.
The determination of the ammonia content in coke-oven gas by means of small gas samples is considered. The results obtained by the standard chemical method and by the proposed method are comparable, but the new method is much faster.
A gas-chromatographic method has been developed for determining the final temperature in the distillation of BS-1 crude benzene (corresponding to the distillation of 97% of the sample). The dependence of that temperature on the total content of mesitylene and indene is established.
