Plan and elevation of acrylonitrile plant made from propylene. This project is a project with an annual output of 160000 tons of acrylonitrile and 80000 tons of acetonitrile. The main products are acrylonitrile and acetonitrile, and the by-products are acrolein, hydrogen, and industrial ammonia. The product structure is more reasonable, the product variety is more diverse, and the enterprise operation is more flexible. The main advantage of this project is the co production of acrylonitrile and acetonitrile. This project has not only obtained main products such as acrylonitrile and acetonitrile, but also by-products such as acrolein and hydrogen with high added value. In the traditional process, the production of acetonitrile mainly depends on the byproduct method of propylene ammoxidation, and the production of acetonitrile is excessive ..
