Embodiment 1

[0050] 1. 1t / h MES particle production line

[0051] Sodium carbonate, 4A zeolite, citric acid (weight ratio 7:9:1) enter the high-shear reactor at a flow rate of 700kg / h and fatty acid methyl ester at a flow rate of 300kg / h, and neutralize and granulate in it; The high-shear reactor is a reactor with a volume of 10L. The average residence time of the material is 10s, and the temperature is raised to 55°C after neutralization. In addition to neutralization to produce moisture; adjust the air pressure to control the particle size of the MES particles;

[0052] The final MES particle indicators are as follows:

Abstract

The invention relates to a process and a device for continuously preparing powdery MES (fatty acid methyl ester sulfonate) particles. A process flow is simple, and the provided preparation device is simple in structure. According to the technical scheme, the process for continuously preparing the powdery MES particles comprises the following steps of (1) causing a powdery mixture of a neutralizer, a wrapper and a stabilizer and fatty acid methyl ester acid ester to enter a high-shear reactor according to a certain proportion; (2) forming MES particles, and causing the MES particles to enter a flash dryer; (3) keeping the obtained MES particles at certain granularity; (4) causing mixed airflow discharged from an outlet of the flash dryer to enter a cyclone separator for separation; (5) obtaining a finished product. The device for continuously preparing the powdery MES particles comprises the high-shear reactor, the flash dryer, the cyclone separator, a bag-type dust collector and an induced draft fan, which are sequentially communicated, wherein the high-shear reactor is provided with an acid ester inlet, a powder inlet, an air inlet and a material outlet communicated with the flash dryer respectively.

Description

technical field [0001] The invention relates to a manufacturing process of surfactant particles, in particular to a manufacturing process of sodium fatty acid methyl ester sulfonate particles. Background technique [0002] Fatty acid methyl ester sodium sulfonate (MES) is a new type of anionic surfactant with excellent performance and broad prospects. It can replace petroleum-based surfactants such as LAS and AOS, and is in line with the overall development trend of resources and the environment. Studies have shown that sodium fatty acid methyl ester sulfonate has excellent decontamination ability, little skin irritation, mild performance, no allergies, low toxicity, high safety, and can be widely used in various liquid and powder detergents. [0003] The main production process of MES is to obtain fatty acids from natural animal and vegetable oils through hydrolysis or saponification and acidolysis, and then esterify with methanol to obtain fatty acid methyl esters, methyl ...
