    After Brazil announced a record sugar crop for this year, with a decline in both ethanol and sugar prices as a result, India too is now preparing for a bumper harvest, a senior economist with the International Sugar Organization said. Raw sugar prices could fall further towards 8 cents per lb in coming months, after their 30% drop so far this year. Converting the global surplus, estimated to be 4 million tonnes, into ethanol may offer a way out of the downward trend. Economic Times India - June 18, 2007.

Scientists develop device to replace distillation, increases energy efficiency of ethanol production

Agricultural Research Service (ARS) scientists in California have developed a new device that could replace the classic distillation process used to obtain ethanol from fermented biomass. The patent-pending technology could cut the energy costs of producing ethanol.

Chemical engineers Richard D. Offeman and George H. Robertson at the ARS Western Regional Research Center in Albany, Calif., think it may be possible to increase the efficiency of ethanol production by using a series of specially designed permeable plastic sheets, or membranes, to produce ethanol from fermented broths of corn, or straw and other kinds of biomass feedstocks.

The researchers' invention, called a spiral-wound liquid membrane module (illustration, click to enlarge), could potentially replace the widely used process of distilling ethanol from fermentation broths. The module offers ethanol producers the important advantage of combining two separation processes, extraction and membrane permeation, in one piece of equipment.

In brief, the process works as follows: the fermentation broth — typically containing about 5 to 12 percent ethanol — would travel through a sandwich-like configuration of membranes and mesh sheets, called spacers, that keep the membranes separate from each other. One membrane has a solvent in its pores that extracts the ethanol from the broth. A second membrane, with the help of a vacuum, pulls the ethanol out of the solvent. The ethanol-and-water vapor that results is then, in other equipment, condensed into an ethanol-rich liquid. The leftover broth could be processed into byproducts:

With further research and development, the module would require less energy than distillation. Today, energy costs are ethanol producers' second largest expense; feedstocks are first.

The scientists have applied for a patent. They now plan to build and fine-tune a prototype, then turn it over to a membrane manufacturer for further development before commercialization.

Already, some ethanol producers have expressed interest in the invention. The technology will help to address the serious concern regarding the energy efficiency of bioethanol production, according to Robert L. Fireovid, ARS national program leader for process engineering and chemistry.

The device has other potential uses, such as cleaning up wastewater or treating natural gas for home use.

The broth flows across the surface of specially designed permeable plastic membranes that are wrapped around the module's perforated collection tube. Ethanol in the broth is separated by the membranes, using a vacuum, then sent to other equipment to be condensed into liquid. Courtesy: Richard D. Offeman and George H. Robertson, USDA-ARS.
