Acetic Anhydride

Acetic anhydride 配图.jpgChemtex is active in supporting clients in developing acetic anhydride projects using acetic acid as a feedstock, via ketene cracking.  We offer very compact design with proprietary ketene cracking and ketene stabilization steps, with a typical plant size of 30,000 tons per year, suitable to produce both “acetylation grade” and “pharmaceutical grade” acetic anhydride.

Our process with unique operating conditions and feedstock composition permit the cracking furnace to operate for more than 2 years without a cleaning operation.
