A kind of oil hydrolysis reactor and reaction process

Abstract

The invention relates to a super-high-efficiency lipid hydrolysis reactor which comprises a raw material lipid storage tank, a water storage tank, a steam inlet tube, a gas-liquid ejection mixer, an inner cylinder, an outer cylinder, a glycerinum flash tank, a fatty acid flash tank, a scraper evaporator, a glycerinum rectifying column and a fatty acid rectifying tower. A high-temperature high-pressure steam power source is adopted, and a gas-liquid ejection mixer is taken as a compulsive material mixing, mass transfer and reaction key component. The invention further provides a reaction process of the reactor. By adopting the reactor, the phase boundary of lipid and water is greatly increased, so that the reaction time of hydrolysis is greatly shortened, on the basis, the reaction temperature and the pressure can be appropriately reduced, so that the energy consumption and the operation cost are reduced, and meanwhile the security coefficient of equipment is increased; the reactor can be used in the hydrolysis process of lipid consisting of different fatty acids, the different fatty acids and glycerinum water can be efficiently separated after the hydrolysis is completed, and a corresponding fatty acid product and a glycerinum product are obtained.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a grease hydrolysis reactor and a reaction process. Background technique [0002] Fatty acid is one of the most basic and widely used chemical raw materials in the field of oleochemicals. Using fatty acids as raw materials, various fatty acid derivatives and various surfactants can be prepared, which are widely used in washing, medicine, cosmetics, plastics, textiles, papermaking, rubber, food, petroleum, synthetic fibers, tanning, mineral processing, machinery, etc. industry. There are two main ways of industrial sources of fatty acids: one is obtained through the hydrolysis of natural oils, and the other is synthesized through petrochemical raw materials. The former is the main method of industrial production of fatty acids at present. The natural oil hydrolysis method can be divided into atmospheric pressure catalytic hydrolysis method, enzymatic hydrolysis method, pressurized...

AI Technical Summary

Problems solved by technology

However, so far, the reaction pressure of this process is mostly as high as 6MPa, the temperature is as high as 275°C, the operation safety is poor, and the requirements for equipment are relatively high, and the production cost is relatively high.

In addition, although the reaction time is shorter than the normal pressure hydrolysis method and the enzymatic hydrolysis method, it is still relatively long, and there is a large room for shortening.
