TAS::89-0227:: Recovery Act - Energy Efficient Reactive Dehydration of Acetic Acid by Hybrid Reactive Distillation and Membrane Separation Project Identification Code:2005501
The overall goal of this SBIR Phase I project was to establish the technical and economic feasibility of an innovative reactive dehydration technology to reduce the energy use in dehydration for the manufacture of acetic acid. Water is an inherent component in the manufacture of acetic acid. Due to the difficulty of multiple azeotropes and other non-idealities, the traditional dehydration of the acetic acid product consumes substantial energy, adds production costs, and generates carbon dioxide. This project addresses these issues by reducing energy consumption, carbon emissions and costs for acetic acid production. A secondary goal was to extend the use of energy efficient membranes to areas not well served at present, such as chemically aggressive or corrosive applications, and removal of water from small molecule chemicals. The project offers a platform technology to extend the applicability of membrane systems.
Based on domestic United States production of acetic acid in 2006, and the required distillation energy per pound of acetic acid produced, the total U.S. energy input required for acetic acid dehydration by 2010 will exceed 10 trillion BTU/year. Reduction of this distillation energy consumption by 50% is the goal of this proposed SBIR program.
