Stamicarbon BV (Sittard, the Netherlands; www.stamicarbon.com), the innovation and license company of Maire Tecnimont Group, has signed a contract for license, process design package (PDP) and proprietary equipment supply for a grass root urea melt and granulation plant for ShchekinoAzot, to be built in Pervomayskiy, Tula region, Russia.
The scope of work for Stamicarbon is the complete license and PDP for a 2,000 metric ton per day (m.t./d) melt and granulation plant including supply of proprietary equipment. The urea melt plant will use Stamicarbon’s Pool Reactor Design and Flash Design. These designs simplify synthesis loop operation, lower investment costs and reduce steam consumption. The Safurex high pressure stripper and pool reactor will be equipped with a radar level measurement system.
The granulation plant will use Stamicarbon’s Optimized Granulation Design and the MicroMist Venturi Scrubber technology. This high-performance multi-stage gas scrubber for granulators is designed to remove urea particles and ammonia gas at extremely high efficiencies. It is capable of meeting most stringent emission levels by capturing submicron dust and removing ammonia efficiently via the injection of an acid solution, while minimizing energy consumption by keeping pressure-drop low.
