Rosatom Completes Upgrade of Lime Milk Purification Equipment at Magnesium Plant

en.Wedoany.com Reported - On November 11, the Solikamsk Magnesium Plant (SMZ), a subsidiary of Russia's State Atomic Energy Corporation Rosatom, completed the replacement of key equipment and related maintenance for its exhaust gas purification facilities, installing a new lime milk classification unit. The equipment is used to process the lime milk reagent employed in industrial exhaust gas purification, removing solid impurities such as sand particles and lime scale from the solution to provide a reagent that meets requirements for subsequent fine filtration and industrial gas neutralization. This modification is part of the plant's planned renewal of production facilities.

The newly installed lime milk classification equipment performs the task of pretreatment for the purification reagent. Lime milk is the primary neutralizing reagent used in the plant's exhaust gas purification facilities; after preparation from water and lime, unreacted solid particles and sediment must be removed. The new equipment performs preliminary separation of the water-based lime milk solution, removing sand particles and lime scale, after which the treated solution enters hydrocyclones for further fine purification. The equipment replacement involved a structural assembly approximately 5 meters tall, with lifting and on-site installation carried out by fitters and welders from the plant's maintenance and construction department.

Supporting modifications are still ongoing. Currently, a new filter unit is under construction in the plant's compressor room, planned to increase filtration capacity, improve system processing efficiency, and distribute equipment operating loads more evenly. This filter is still in the construction phase and represents a different construction milestone from the already completed installation of the lime milk classification equipment.

This modification also connects with the plant's previously carried out production equipment renewal. The Solikamsk Magnesium Plant has already completed a major overhaul of its limestone calcination unit and installed new equipment in the calcium chloride preparation section, including filter press equipment used to purify calcium chloride solution. The related modifications involve auxiliary production stages including limestone raw material handling, chemical preparation, and industrial exhaust gas purification.
