Membrane systems for separation of methanol and ethanol from organics

New pervaporation membranes and systems have been developed for the separation of methanol from hydrocarbons and ethanol from ethers and other organics. The main applications are in methyltetrabutylether (MTBE) and ethyltetrabutylether (ETBE) production plants with other potential uses being in the chemical and petrochemical industries. In comparison with the traditional technology these systems are advantageous with respect to energy saving and lower investment and operating costs.

Furthur applications are found and have been tested in the seperation of methanol and ethanol out of their azeotropic mixtures with other organic components, especially the retrospective esters.
