The equipment for electrolysis was delivered on the RusVinyl PVC plant construction site. Rusvinyl has opted for the modern membrane bipolar electrolysis technology, supplied by German manufacturer UHDE, given the good combination of environmental-friendliness, low energy consumption, capital cost, and product quality. The use of the membrane electrolysis allows, compared with the traditional technologies, to reduce the electrical power consumption by approximately 30%.
In total six electrolysers will be put in operation, allowing an annual chlorine production of 205.000 tons. All the chlorine volume will be sent to the VCM unit; while the caustic soda produced in the electrolysis will be sold on the commercial market, and the by-product hydrogen will be re-injected in the production process as pyrolysis fuel.
Electrolyzers and other additional electrolysis equipment are actually on the construction site and are being inventoried. The assembly of the unit will start next spring with the assembly of the necessary racks.
In general, the construction works are progressing. Some elements like the technical buildings and the buildings for the electrical substations are completed. Currently, more than 290 units of equipment, including 19 big-sized and heavy facilities have been already installed in the production zones. The overall project progress, including engineering, procurement, and construction is about 70%.
