Two Hundred Thousand Tons Of Acetic Acid Plant Technological Upgrading And Industrial Demonstration

Based on the review of developing trend of acetic acid producing and Its market supply and demand situation both at home and abroad, this paper introduced main industrial processes. this paper introduces a guo ai company of acetic acid, in the implementation of devices for20×104tons/year device expand produces the transformation, and through the upgrade technology to realize the goal of annual capacity of30x104tons of acetic acid, through the research and development of high performance catalyst, the existing device extension make existing guotai company of acetic acid catalyst to realize common device, technology, large-scale scale renewal and increase economic efficiency, reduce unit product production cost, improve the competitiveness of the industry of acetic acid necessary way.Example of Guotai Company with20x104tons/acetic acid plant modification project, consider confidential principle, this paper briefly narrated the reconstruction process. Determine the success of the expansion to affect device production bottleneck. Then, through the engineering measure to existing devices reaction, distillation system reform and key equipment, realize the expansion of one hundred thousand tons goals. Device With high performance of the test of success, improve catalyst Guotai Company20×104tons/acetate device the reconstruction project in May2009, unit production capacity by the original20×104tons/year to3O×104tons/year. Device In addition reduced production cost, the actual production of acetic acid has important significance.
