Voskresensk Mineral Fertilizers are getting prepared for the autumn overhaul

Voskresensk Mineral Fertilizers (part of Uralchem) is preparing for a shutdown maintenance campaign. According to the approved schedule, the main works will be completed in September-October 2021.

The autumn repair campaign will be the largest in the last decades in terms of scale and scope of work.

Along with repairs, it’s planned to replace production equipment in the basic workshops of the enterprise, which are part of the chain for the production of mineral fertilizers. The contact sulfuric acid workshop will receive a new drying tower. These works will mark the end of one of the stages of technical re-equipment of the sulfuric acid workshop with the replacement of three towers on the SK-48 unit. As part of the overhaul, it’s planned to replace metal structures in the sulfur filtration department, as well as in the contact and the drying-absorption departments with a total weight of over 95 tons.

It’s planned to replace vacuum evaporation units No.2 and No.3 in the wet-process phosphoric acid workshop. Besides, the company will repair the belt and carousel filters, mixing devices, ventilation, and pumping equipment in this workshop. By the way, works to ensure chemical protection of floors in the acid warehouse have already begun in August.

Back in May, the ammophos workshop No.2 held a competition to choose a contractor to repair its drying drums. During the autumn maintenance campaign, the workshop will repair elevators, conveyors, screens and furnaces, absorption systems, ammonia lines, and a finished product warehouse. The department of complex mineral fertilizers will carry out maintenance of pumping and transporting equipment and press filters.

Similar works will be conducted in ammophos workshop No.1. Besides, it’s planned to lay a new additional gas line, which will pass through the entire workshop.

“Preparations for the maintenance campaign started at the beginning of 2021 with the preparation of accounting and picking lists and filing applications for the materials,” said Sergei Mosichev, Chief Mechanic at Voskresensk Mineral Fertilizers. “As of today, we have completed tendering procedures and selected contractors for all the main objects. We have also carried out large-scale work on the preparation of the materials and the manufacture of non-standard assemblies and parts required for the overhaul. I’m confident that we will be able to complete the upcoming large-scale maintenance campaign in a short time and at the highest level, which will ensure the stable operation of all production lines of the enterprise throughout the entire year.”
