Overview The double-column distillation production of the general-grade alcohol process mainly consists of the fine tower II, the coarse tower II, the refined tower I, and the coarse tower I. One system contains two coarse towers, two fine towers, and one tower enters the steam four towers. The differential pressure between the tower and the tower and the temperature difference are used to gradually exchange heat through the reboiler to achieve the purpose of energy saving. In the work, the t...
Overview The five-tower three-effect is a new energy-saving technology introduced on the basis of the traditional five-tower differential pressure distillation, which is mainly used for the production of premium grade alcohol. The main equipment of the traditional five-tower differential pressure distillation includes a crude distillation tower, a dilution tower, a rectification tower, a methanol tower, and an impurity tower. The heating method is that the rectification tower and the dilution...
Overview For the characteristics of “high salt content” of waste liquid produced in cellulose, salt chemical industry and coal chemical industry, the three-effect forced circulation evaporation system is used to concentrate and crystallize, and the supersaturated crystal slurry is sent to the separator to obtain crystal salt. After separation, the mother liquor returns to the system to continue. Circulating concentration. The device is controlled by automatic program. Evaporation ...
Threonine introduction L-threonine is an essential amino acid, and threonine is mainly used in medicine, chemical reagents, food fortifiers, feed additives, etc. In particular, the amount of feed additives is increasing rapidly. It is often added to the feed of juvenile piglets and poultry. It is the second restricted amino acid in pig feed and the third restricted amino acid in poultry feed. Adding L-threonine to compound feed has the following characteristics: ① It can adjust the amin...
Molasses alcohol waste liquid five-effect evaporation device Overview Source, characteristics and harm of molasses alcohol wastewater Molasses alcohol wastewater is high-concentration and high-color organic wastewater discharged from the alcohol workshop of the sugar factory to produce alcohol after the fermentation of molasses. It is rich in protein and other organic matter, and also contains more inorganic salts such as Ca and Mg and higher concentrations. SO2 and so on. Normally, the ...
Summary The containing Pentosan plant fiber materials (like Corn cob, peanut shells, cotton seed hulls, rice hulls, sawdust, cotton wood) will hydrolysis into pentose in the fluence of the certain temperature and catalyst, Pentoses leave off three water molecules to form furfural The corn cob is used by the materials usually, and after a series of process that include Purification, crushing, with acid hydrolysis, mash distillation, neutralization, dewatering, refining get the qualified f...
Hydrogen peroxide production process The chemical formula of hydrogen peroxide is H2O2, commonly known as hydrogen peroxide. Appearance is a colorless transparent liquid, it is a strong oxidant, its aqueous solution is suitable for medical wound disinfection and environmental disinfection and food disinfection. Under normal circumstances, it will decompose into water and oxygen, but the decomposition rate is extremely slow, and the speed of the reaction is accelerated by adding a catalyst ...
National invention patent The characteristics and treatment method of furfural wastewater: It has strong acidity. The bottom wastewater contains 1.2%~2.5% acetic acid, which is turbid, khaki, light transmittance <60%. In addition to water and acetic acid, it also contains extremely A small amount of furfural, other trace organic acids, ketones, etc. The COD in the wastewater is about 15000~20000mg/L, BOD is about 5000mg/L, SS is about 250mg/L, and the temperature is about 100℃. If the was...
