Problems solved by technology
The investment in sewage treatment equipment is large, and most manufacturers are unwilling to invest, and sewage discharge has a considerable impact on the environment; qualified manufacturers have installed sewage treatment equipment, but the cost of water treatment is high, which affects the economic benefits of enterprises
There are also some methods for dephosphorization with biological enzymes (such as: No. 96195847.2 patent and No. 99804005.3 patent application), but the method has complex defects

Embodiment 1
[0020] To make 1000 grams of dephosphorization agent, take 750 grams of clay with high montmorillonite content, 200 grams of silicate, 20 grams of citric acid with a concentration of 95%, and 30 grams of perlite (filter aid). A product is formed, and its dephosphorization effect is 98.5%.
Embodiment 2
[0022] To make 1000 grams of dephosphorization agent, take 780 grams of clay with high montmorillonite content, 180 grams of silicate, 20 grams of citric acid with a concentration of 95%, and 20 grams of perlite (filter aid). A product is formed, and its dephosphorization effect is 99%.
Embodiment 3
[0024] To make 1000 grams of dephosphorization agent, take 800 grams of clay with high montmorillonite content, 150 grams of silicate, 20 grams of citric acid with a concentration of 95%, and 30 grams of perlite (filter aid). A product is formed, and its dephosphorization effect is 98.2%.
[0025] The using method of the present invention is:
[0026] 1. Sampling the measured crude oil to check its phospholipid content;
[0027] 2. Raise the oil temperature to 60°C-70°C, slowly add the dephosphorizing agent to the crude oil at a rate of 2-2.5 times the phospholipid content of the crude oil (for example: there is 100 kg of crude oil, the phospholipid content is 0.5%, the dephosphorizing agent Add twice the content of phospholipids, that is, add 1 kg of dephosphorizing agent), and stir rapidly for 10-15 minutes;
[0028] 3. Filter the dephosphorized oil to obtain ideal dephosphorized oil or refined oil;
[0029] 4. Routine inspection method for dephosphorization effect: Take ...

Abstract
The invention relates to a vegetable oil dephosphorization agent using a physical adsorption method, which is prepared by mixing and stirring clay with high montmorillonite content, silicate, citric acid and filter aid. According to the invention, the clay with high montmorillonite content has It has strong adsorption capacity for phospholipids, no need for hydration, just add dephosphorizing agent to crude oil in proportion, stir for 10-15 minutes, and get ideal dephosphorized oil after filtering. For the crude oil that does not need deacidification treatment, the dephosphorized oil is the refined oil (oil products above grade 4 of the national standard). The invention has the advantages of high refining rate, electricity saving, steam saving, labor saving, no oil waste and no sewage discharge, and is a long-awaited good product for energy saving, efficiency enhancement and environmental protection in every vegetable oil factory.
Description
technical field [0001] The invention belongs to the category of vegetable oil processing, in particular to a vegetable oil dephosphorization agent using a physical adsorption method for oil refining in vegetable oil factories. Background technique [0002] The hydration dephosphorization process is widely used in the oil processing industry, that is, the principle of hydrophilicity of phospholipids is used. During oil refining, heating, water addition, stirring, precipitation and other processes can be used. There are long dephosphorization time and non-hydratable phospholipids It cannot be removed, the refining rate is low, the oil foot is difficult to deal with, the energy consumption is large, the labor is large, the waste water is large, the production cost is high, and it is not conducive to environmental protection. At present, there are two types of oil refining methods in the oil processing industry: intermittent refining and continuous refinin...
