Abstract

The invention discloses a high-pressure hydrolysis tower, and belongs to the field of oil chemical industry. The high-pressure hydrolysis tower comprises a tower body, wherein a water inlet and a material outlet are formed on an upper section of the tower body; an exhaust port is arranged at the upper end of the tower body; an oil inlet and a drainage port are formed on the lower section of the tower body; and a plurality of steam distributors are arranged on the tower body from top to bottom; the high-pressure hydrolysis tower is characterized in that a plurality of oil-water separators are uniformly distributed between the water inlet and the oil inlet in the tower body from top to bottom. The high-pressure hydrolysis tower has the benefits that 1, separation is realized through an oil-water passage and the oil-water passage is protected from being touched; 2, the oil-water contact area is increased; 3, the hydrolysis rate is improved from 98% to be above 99.5%; and 4, the hydrolysis efficiency in oil chemical production is improved.

Description

technical field

[0001] The invention belongs to the field of oleochemical industry, in particular to a high-pressure hydrolysis tower. Background technique

[0002] At present, most domestic oleochemical companies use hydrolysis towers to hydrolyze oil to produce fatty acids and glycerin. Oil can be hydrolyzed under the condition of acid or alkali catalysis, and the main processes include low-pressure hydrolysis, medium-pressure hydrolysis and high-pressure hydrolysis. High temperature and high pressure non-catalyzed hydrolysis is a production process with the best effect.

[0003] Due to the high temperature and high pressure convective hydrolysis process used in the existing high temperature and high pressure hydrolysis tower, the oil and water cannot be fully contacted. Using the density difference, water is injected from the top of the hydrolysis tower, grease is injected from the bottom of the tower, and the hydrolysis reaction is completed through the oil-water convec...
