OREANDA-NEWS. January 29, 2009. Kemerovo. The setting-up of the new quartz sieve is carried out at chemical products interception workshop #1 of OJSC “Koks”. It’s a new experimental production piece of quartz sieve. Lack of refrigerating systems and impossibility of coke gas deep initial cooling (characteristic for round phosphate cleaning method used) caused mud accumulation on piping systems, consequently, it conditioned the necessity of the sieve installation. Fine solution cleaning will allow to extend distance run between overhauls and equipment campaign. It is also planned to set up similar sieves for ammonia-aqua cleaning
