Manufacturing Technology of Double Tube Plate Heat Exchanger

白银Manufacturing Technology of Double Tube Plate Heat Exchanger

Double tube plate is a common structure in heat exchanger in recent years. In order to avoid the mixing of the two media in the tube side and the shell side to scrap the material or cause a major accident, the double tube plate structure is generally used.

Design and Development of SMPO Wastewater Three-effect Evaporator

白银Design and Development of SMPO Wastewater Three-effect Evaporator

The wastewater produced in the SMPO production process is extremely difficult to treat due to its high temperature, high alkalinity and high chemical oxygen demand, resulting in the survival of biochemical treatment strains. However, biochemical methods are currently used to treat SMPO wastewater in China. In view of the salt-containing industrial wastewater from SMPO plant, Ruikai Chemical has developed a more concise multi-effect evaporation treatment equipment. The wastewater from styrene/propylene oxide cogeneration plant is concentrated by evaporation technology. The concentrated high salt-containing wastewater is incinerated, while the distilled water from salt removal is sent to biochemical treatment, which solves the problem that salt-containing wastewater cannot be biochemically treated. This set of equipment can not only reduce the cost of SMPO wastewater treatment, but also save land, which is very valuable for chemical plants or other devices.

Manufacture of key equipment for propylene oxide/styrene co-production technology

白银Manufacture of key equipment for propylene oxide/styrene co-production technology

Propylene oxide is the third largest propylene derivative after polypropylene and acrylonitrile. It is mainly used in the production of polyether, propylene glycol, etc. Its derivatives are widely used in automobile, construction, food, tobacco, medicine and cosmetics industries. Nearly 100 kinds of downstream products have been produced, which are important raw materials for fine chemical products.
