Help: How to increase the acid value during the hydrolysis in a gleditsia hydrolysis tower. Medium-pressure steam hydrolysis. The hydrolysis products include linoleic acid, oleic acid, palmitic acid, stearic acid, etc. A generous reward will surely be given!
What the original poster means by increasing the acid value is actually increasing the hydrolysis rate. The operating conditions of your hydrolysis tower are not specified; I suggest you start by checking the following points: 1. Whether the temperatures in each stage of the hydrolysis reaction section of the hydrolysis tower meet the required operational standards, and whether the temperature gradient is normal ； 2. Your reaction tower should have water fed in from the top, right? If so, you can verify this or gradually adjust the \"feed ratio of water to oil\"” ； 3. Oil inlet temperature and water inlet temperature.
The operating pressure is 15 kg of gauge pressure; water is fed at the top of the tower, while steam is supplied to the bottom of the tower and the steam pipes inside it; water and oil are fed separately.
The temperatures and pressures required for the hydrolysis of different raw materials vary, and there are also significant differences among different hydrolysis towers. Your hydrolysis tower’s hydrolysis section should have 2 to 4 temperature measurement points. Examine carefully whether the temperatures at these points in the hydrolysis section meet your process specifications, and whether the hydrolysis section is being utilized fully. Furthermore, according to the hydrolysis reaction equation, high water concentration and low glycerol concentration in the reaction system facilitate the progress of the reaction ； However, if the water volume is too high, the temperature will be low and the glycerol load in the post-treatment process will be high. Therefore, it is necessary to balance the feed ratio and the temperatures in the hydrolysis section.
