1. Response enhancement

High-shear and strong mixing reactor, tubular reactor and tower reactor

TDI and MDI phosgene reactors: industrial implementation effects: reduce tar production by 30% and steam consumption by 40%.

Sulfonation, polymerization, oxidation, esterification and other processes

Preparation of pesticide suspension/water emulsion: the fineness is increased from 100μm to 50μm, and the time is shortened by 50%.

Uniform mixing of high solid content system: The mixing quality is improved, the time is shortened to 20%-25%, and the installed power is halved.
 

2. Process enhancement class-process enhancement and system integration

Phosgene chlorination produces methyl chloroformate, and the product yield is increased from 88-90% to over 98%. Realize the whole continuous process of reaction dephosgene and reaction tail gas treatment.

Continuous resin polymerization, product quality is stable, reaction pressure is reduced, reaction time is shortened by 50-80%, and conversion rate: 95% is increased to over 99.9.
System thermal integration

◆ 100,000 tons/year caprolactam device, saving 80,000 tons of steam/year, saving energy costs of 12 million yuan (150 yuan/ton of steam), and recovering investment in 2 to 3 months.

◆ Recovery of glycine mother liquor wastewater: The secondary steam used for evaporative desalination is used in the methanol tower to save more than 50% of energy. The 10,000 tons/year glycine plant saves 72,000 tons of steam per year.

◆ Pesticide production wastewater recovery: DMF 10%, potassium chloride 10%, water 80%, "rectification-evaporation-rectification" combination DMF recovery, potassium chloride recovery Advantages: multi-effect coupling, less steam, energy-saving evaporative distillation, Avoid tower blockage, less DMF decomposition and high yield.
