Problems solved by technology

[0004] In the actual production process, there are defects in this method. The conversion rate of total phosphorus in ECO oxidation treatment is about 89%. The unconverted phosphorus needs to be intercepted by reverse osmosis membrane and then sent to ECO treatment. The cost of filter element consumption is high; the COD conversion rate is also low, about 75%; the ECO oxidation reaction is high temperature and high pressure, which is dangerous and corrosive to the equipment, and the service life of the equipment is short

Embodiment 1

[0039] The present invention utilizes copper nitrate trihydrate to have strong catalytic properties. Copper nitrate trihydrate begins to decompose at 170°C, and its copper ions can reduce the positive reaction activity of organic phosphorus and macromolecular COD, and increase its oxidation reaction rate. Under the conditions far lower than the current status of the ECO device operation process, the phosphorus and COD in the mother liquor are converted into small molecular inorganic phosphorus and small molecular gas. The gas is treated by the ammonia nitrogen absorption device and discharged up to the standard. The inorganic phosphorus is cooled and crystallized in the extraction process to produce the product mixed phosphoric acid Sodium salt (not less than 90% disodium hydrogen phosphate), the raffinate is sent to the MVR process to continue to do steaming salt (sodium chloride) treatment.

[0040] Specifically, it is a catalytic oxidation treatment process of glyphosate mot...

Abstract

The invention relates to glyphosate mother liquor catalytic oxidation treating equipment and process. The glyphosate mother liquor catalytic oxidation treating process comprises the following steps: after mixing a copper nitrate.gibbsite solution serving as a catalyst, and a glyphosate mother liquor by virtue of a static mixer, carrying out a catalytic reaction under an oxidation system with the temperature of 210+ / -5 DEG C and the pressure of 4MPa, wherein the oxidation system is a circulation loop comprsing a tubular heat exchanger, a tube heat exchanger, a medium-pressure heat exchanger, a coil heat exchanger and a tube heat exchanger. With the adoption of the glyphosate mother liquor catalytic oxidation treating equipment and process, the realistic problems of incomplete oxidation reaction, high temperature and pressure of the oxidation reaction, large risk, large corrosion of the reaction to the equipment and the like of the glyphosate mother liquor oxidation reaction are solved; after a homogeneous catalyst is added, the reaction rate is greatly increased, the oxidation reaction is complete, the temperature and the pressure of the device system are lowered, the equipment corrosion condition is improved, and a novel perfect and reliable process is provided for ECO treatment of the glyphosate mother liquor.

Description

technical field [0001] The invention relates to a glyphosate mother liquor oxidation treatment process. The purpose of the invention is to solve the problems of incomplete oxidation reaction of glyphosate mother liquor, low conversion rate of total phosphorus, low conversion rate of COD, high risk of equipment, serious corrosion during operation, To overcome the problems of high operating costs, a new process for the catalytic oxidation of glyphosate mother liquor is provided. Background technique [0002] Glyphosate is a systemic, chronic, high-efficiency, low-toxicity, broad-spectrum, and total herbicide. It was first developed by Monsanto in the United States and has a production and use history of more than 40 years. Glyphosate raw powder is a non-volatile white odorless solid, which melts and decomposes at about 230°C. It is insoluble in common organic solvents and can form salts with inorganic (organic) bases. It is often formulated into ammonium salts, isopropylamine ...
