Embodiment Construction

[0026] In order to further illustrate the technical means adopted by the present invention and the technical effects achieved, the following will be described in detail in conjunction with the examples.

[0027] The purification process of a kind of fatty acid methyl ester sulfonate MES of the present invention is characterized in that: it comprises the steps:

[0028] 1. Extract the methanol in the methanol tank V101ab through the methanol delivery pump P101 and send it to the dissolution kettle R101;

[0029] 2. The raw material delivery pump P102 pumps out the raw materials from the raw material tank V102 and the raw material inlet, and the outlet of the raw material delivery pump P102 is respectively connected to the raw material tank V102 and the dissolution kettle R101, and the connecting pipes are respectively provided with valves A1 and A2;

[0030] 3. From the top of the dissolution kettle R101, add methanol and raw materials successively for dissolution;

[0031] 4....

Abstract

The invention provides a purification process of fatty acid methyl ester sulfonate MES. The method comprises the following steps: adding metered methanol into a 3000L reaction kettle; pumping 3.6 tonsof MES with the active matter content of about 65%-75% through a raw material tank; adjusting the temperature of the feed liquid until the solution is clear, pumping the solution into a 3000L pre-cooling kettle for preliminary cooling, pumping the solution into a copious cooling kettle for further cooling to a specified temperature, crystallizing for a period of time, continuously pumping the solution into a vacuum rotary centrifuge through a freezing discharge pump, and separating liquid and solid materials, and crushing the solid materials by a crusher and then continuously entering a drying auger and a cooling auger to prepare the MES with the active matter content being 90% or above. The process also has the advantages of saving energy consumption, protecting the environment, comprehensively utilizing energy transfer and the like.

Description

technical field [0001] The invention belongs to the technical field of oleochemical industry, in particular to a purification process of fatty acid methyl ester sulfonate MES. Background technique [0002] Fatty acid methyl ester sulfonate MES is a high-efficiency surfactant made of natural animal and vegetable oils. It has good wetting, emulsifying, soft and hard water resistance, good solubility and high biodegradation rate. Small skin irritation, strong foaming power. In the civil field, it is used in low-phosphorus or phosphorus-free laundry detergent; the active substance of soap and complex soap and the dispersant of calcium soap. [0003] In the industrial field, it is used as an emulsifier in the plastic industry, a cell opener, a release agent for rubber products, a dyeing auxiliary in the printing and dyeing industry, textile printing and dyeing, a color developer, and a wetting agent and dispersion for dyes, pigments, and agricultural chemicals. Chemicals, ore d...
