In the field of pesticide intermediate production, high efficient and accurate separation technology is essential for improving product quality and reducing production costs. Our LC-350 centrifugal extractor has shown significant application advantages in the production of pesticide intermediates with its excellent performance and advanced technology.

1. Case Background
A pesticide intermediate production company faces problems such as low efficiency, high energy consumption, and unsatisfactory separation effect of traditional extraction equipment during the production process. These problems lead to unstable product quality and high production costs, which seriously affect the company's market competitiveness. In order to solve these problems, the company decided to introduce LC-350 centrifugal extractor of Shandong Liancui for process upgrade.

2. Equipment advantages
The LC-350 centrifugal extractor has many significant advantages. It adopts an upper suspension structure without a bottom bearing, which avoids the risk of leakage and ensures the stable operation of the equipment. The drum diameter is 350mm, and the flux range covers 500-8000L/h, which can meet the production needs of different scales. The main body of the equipment is made of SS316L and steel-lined fluorine composite structure, which has excellent acid and alkali corrosion resistance and can run continuously for 5000 hours without corrosion leakage in a strong acid environment of pH ≤ 2. In addition, the equipment is also equipped with an intelligent control system that can monitor key parameters such as drum speed, two-phase interface position, flow rate, etc. in real time, and support remote fault diagnosis and process optimization.

Application process

Raw material introduction
The leachate containing the target pesticide intermediate and the organic extractant are introduced into the mixing chamber of the LC-350 centrifugal extractor through the feed port respectively. In the mixing chamber, the stirring paddle rotates at high speed to make the leachate and the extractant fully contact and mix.

High Efficient separation
Under the centrifugal force generated by the high-speed rotating drum, the denser water phase (containing impurities) is thrown to the drum wall, while the less dense organic phase (loaded with the target pesticide intermediate) is concentrated in the central area to achieve efficient separation. The separated two-phase liquid is discharged from the equipment through different outlets.

Multi-stage of centrifugal extractor series connection
In order to further improve the separation effect and product purity, the company adopted a multi-stage series connection process. Connect multiple LC-350 centrifugal extractors in series, so that the leaching liquid and the extractant are extracted and separated in turn in the multi-stage equipment. By adjusting the speed and ratio (O/A) of each stage of equipment, the separation efficiency of each stage is optimized.
Application Effect
Improved Extraction Efficiency
Compared with traditional extraction equipment, the extraction efficiency of the LC-350 centrifugal extractor has been significantly improved. In the production of a certain pesticide intermediate, the single-stage extraction rate has increased from the original 60% to more than 85%, and the extraction rate can reach more than 95% after multi-stage series connection.

Improved Product Purity
Through the multi-stage series process, the purity of the target pesticide intermediate has been greatly improved. In a certain case, the product purity has increased from the original 80% to more than 99%, meeting the needs of the high-end market.

Reduced Energy Consumption
The LC-350 centrifugal extractor adopts an independent mixing chamber design and an optimized stirring paddle structure to reduce energy consumption. Compared with the traditional annular gap extractor, the energy consumption is reduced by more than 20%. At the same time, the intelligent control system of the equipment can automatically adjust the operating parameters according to the actual working conditions, further reducing energy consumption.

Reduced operation and maintenance costs
The corrosion resistance and stable operation of the equipment reduce the number of equipment maintenance and repair costs. In addition, the application of intelligent control systems reduces the risk of manual intervention and reduces labor costs. According to company statistics, after the introduction of the LC-350 centrifugal extractor, the operation and maintenance costs have been reduced by more than 30%.
