Batch drying of acetic acid by azeotrophic distillation

Article Abstract:

A study used the process simulator called CHEMCAD to demonstrate a technique by which acetic acid containing 15 wt% water can be dehydrated using batch distillation with ehtyl acetate as an entrainer. The process is based on the fact that ethyl acetate and water form a minimum boiling, heterogeneous azeotrope, which splits into easily separable organic and aqueous liquid phases when condensed. CHEMCAD considerably facilitates this procedure by allowing users to start and stop the simulation based on specified events or times.

Increasing acetic acid production by leaps and bonds

Article Abstract:

Celanese Chemicals of Kronberg, Germany, has significantly increased the acetic acid output of its plant in Clear Lake, TX, by using its proprietary acid optimization technology, called AO Plus. The company expects, that by the end of 2001, when the technology is full implemented, the facility's capacity will increase by 20% to an annual 1.2 million metric tons of acetic acid.

Microbial fuel cells generate H(sub 2) from acetic acid

Article Abstract:

Researchers Bruce E. Logan and Sharon Cheng have developed a new way of converting cellulose and other biodegradable organic materials to hydrogen. Naturally occurring bacteria in a microbial electrolysis cell with acetic acid are used in the process. According to Logan, this hydrogen could be blended with natural gas, which may be used in natural-gas vehicles.
