Nikkei. Mitsui Engineering & Shipbuilding Co. (MES) says that it has developed a technology that boosts output of bioethanol fourfold compared with conventional methods.
The unique process involves the use of a special yeast developed in-house for the fermentation of sugars extracted from cane and other raw materials. Efficiency is enhanced through new techniques that allow the yeast to remain active in fermentation tanks even under high temperatures and other extreme conditions.
As a result, bioethanol output per liter of raw material is increased to 20 grams from about 5 grams now. The firm has completed work on the design of the production system and is ready to begin shipping it after conducting tests.
Mitsui Engineering has received an order a system for equipment capable of producing 1,000 kiloliters of bioethanol annually using rice as a raw material. MES continues to test systems for the production of cellulosic ethanol. (Earlier post.)
MES has also developed a zeolite membrane for use in dehydration systems for bioethanol plants that helping to reduce process fuel consumption by around 10% compared to other methods. (Earlier post.)
