Ethanol is an important chemical raw material that can be used to make acetic acid, beverages, flavors, dyes, fuels, etc. It is widely used in national defense chemical industry, medical and health, food industry, industrial and agricultural production. Everyone knows that grain can be used to make wine. Have you ever thought about using the exhaust gas from a steel mill to produce alcohol? In fact, the use of exhaust gas from steel mills to produce ethanol not only reduces pollution, but also reduces production costs by 30%.
This process requires a kind of magic bacteria which can ferment exhaust gas from steel mills to produce ethanol. This kind of bacteria is oxygen-consuming. Under a certain oxygen concentration, its growth rate is proportional to the oxygen supply. The way to achieve the highest conversion rate is to find an optimal gas distribution method.
The answer is to use porous sintered metal as a gas sparger. The advantage of this kind of sparger is that it can break the gas into micron-sized bubbles, increase the oxygen concentration in the fermentation broth as much as possible, and ensure a mild environment for the fermentation broth, which is conducive to the work of bacteria. Compared with other gas distribution methods, porous metal can reduce gas consumption without causing severe disturbance of fermentation broth.
Shinkai has been working in this field for many years and now has the ability to design a full set of gas sparge. Now, the gas sparges designed by Shinkai is used in the fermentation equipment of many steel plants around the world. As long as you tell me the size of the fermentation tank and the required amount of aeration, Shinkai will customize a set of sparge with the best effect for you.
If you think you might need ways to improve gas distribution efficiency or increase bacterial fermentation efficiency. Please feel free to contact us. Shinkai will specially customize the full-process system solutions for you, including but not limited to sparge design and selection, process design, instrument and valve selection, piping design, etc.
