Investigation of the speed of a gas-liquid mixture during processing of plant raw materials
Abstract
The article deals with the determination of the rotation speed of the gas-liquid mixture at the vortex contact stage during rectification of ethanol obtained on the basis of the hydrolyzate of plant raw materials. Ethanol, obtained on the basis of hydrolyzate plant mass, can not be better suited for the organization of technology to produce fuels from renewable sources of raw materials. The use of alcohols in gasolines, in addition to purely technical problems associated with the preparation of compositions with corresponding octane numbers, can significantly improve the environmental performance of fuel by reducing the content of benzene and aromatic hydrocarbons, which leads to a decrease in the content of toxic substances in combustion products. It has been established that the addition of absolute ethyl alcohol to gasoline increases the antiknock properties of motor fuel, which makes it possible to apply higher compression ratios. In addition, more complete combustion of alcohol fuels is realized, which not only increases efficiency, but also weakens such harmful phenomena as liquefaction of liquids and formation of deposits, and thereby significantly extends the life of the motor. Alcohol fuels have, in comparison with gasoline, a wider range of flammability of the combustible mixture, thereby increasing the steady operation of the motor.
