Intermittent chemical washing/alkali washing/pickling technical improvement projects can choose multi-stage continuous centrifugal extractor

Pickling, alkali washing and water washing are very common in the chemical production process. Its purpose is, for example, to remove inorganic salts in organic matter by adding water, Most of this process section is completed by batch reactors at home and abroad. At present, most of the production process adopts intermittent operations of adding water to the washing tank, stirring, standing, and artificial layering. So, what are its pros and cons?

1. Advantages of batch reactor: The advantage of the reactor is that each device operates independently, is controlled independently, and does not interfere with each other.
2. Disadvantages of batch reactor:
① This operation is intermittently produced, and the process takes a long time. It is necessary to manually stare at the glass sight glass of the feeding tube in real time on site, and damage the eyes of the operator;
②Manpower consumption increases production costs, and the quality of batch products cannot be stabilized;
③ Further expand the product scale according to market demand. If large-scale equipment (for example, more than 10,000L kettle) is used, the output of a single reactor can be increased, but due to the increase of the reactor, the mass transfer efficiency is worse, and the product quality and yield are even worse. It is difficult to meet the process requirements.
④ The larger the batch reactor, the greater the risk of its operation.

In order to ensure product quality and yield, increase output, and meet continuous production requirements, existing processes often use multiple new Liquid Liquid Centrifugal Extractor. Zhengzhou TIEI Extraction CWL-M series new centrifugal extractor can realize continuous extraction of organic layer and water layer, can completely replace various traditional extraction kettles, reduce solvent consumption, save operating time, reduce energy consumption, reduce three wastes, and at the same time meet Large-scale production needs, it is a new generation of ideal high-efficiency, green, continuous extraction equipment.

TIEI Extraction is mainly committed to the research and development and application of liquid-liquid mixing and separation equipment. The company adheres to the business philosophy of "integrity, professionalism, pragmatism and innovation", with professional processing equipment, strict quality control system, high-quality technical research team and Perfect after-sales service, committed to providing every customer with a full range of technical solutions. At present, TIEI Extraction CWL-M new Liquid Liquid Centrifugal Extractor has been widely used in various organic synthesis extraction and separation sections such as fine chemical industry, raw material drug production, intermediate production, etc., successfully replacing the original batch reactor, such as n-hexane extraction and hydrogenation Calcium reactor technological transformation project, pharmaceutical intermediate extraction reactor technical transformation project, fine chemical continuous washing technical transformation project, methylene chloride continuous technological transformation project, continuous pickling + water washing technological transformation project, etc., have achieved remarkable application results.
