This piece of equipment worth nearly 100 million yuan was transported to the site by a special transport team that imported materials from domestic foreign-funded enterprises. The tower is 50 meters high, has a net weight of 48 tons, and is made of pure zirconium material. This equipment adopts methanol low-pressure oxo synthesis technology, which is currently the most advanced, most economical and most suitable technology in my country's resource conditions. The raw materials are methanol and carbon monoxide, which react in the reactor to generate acetic acid. After flash evaporation, they are purified into the finished product acetic acid in the distillation system. The dehydration tower is large in size and complex in structure. It is one of the indispensable key equipment in the production of acetic acid.
