The Nvoi PVC Complex Project in Uzbekistan is an important project to promote international production capacity cooperation under the "One Belt And One Road" initiative. It is the first set of PVC installation successfully completed in Uzbekistan, and also the largest general contract project implemented by a Chinese enterprise in Uzbekistan. The project includes 100,000 tons of PVC, 75,000 tons of caustic soda and 300,000 tons of methanol production lines. ZYUC is lucky to participate in this very meaningful project. Our company organized a professional start up team of PVC plant production line and natural gas--acetylene plant production line to Uzbekistan to carry out technical services, covering technology, production management and operation of mechanical and electrical instrument technology, analysis, and other various professional work, help the contractor to the engineering group in the project of PVC production and natural gas--acetylene production check before start up debugging, mid-term production operations, training guide and other related work. The arrival of the COVID-19 epidemic has brought great interference to the progress of the project. Our staff stick to their posts and obey the overall situation, and do a good job of epidemic prevention measures while insisting on production. Through efforts, PVC production has reached capacity and operation, natural gas acetylene production due to the upstream influence is still in the process of debugging and elimination of deficiency.
