Fine Chemical

This bromine-phosphorus flame retardant manufacturer produces 23,000 tons of tetrabromobisphenol A and decabromodiphenyl ethane annually. The production process generates 5 m³/h of highly concentrated saline mother liquor with a complex composition: NaCl 12%, Na₂SO₄ 8%, sodium bromide 3%, zinc borate 1%, organophosphorus 0.5%, COD 20,000 mg/L, pH 1–2. The raw water is classified as HW18 hazardous waste, with an outsourced disposal cost of 2,800 RMB/ton and an annual cost of nearly 120 million RMB. The company urgently needs a comprehensive solution for "reduction of mixed salts + resource utilization".

Adhering to the circular economy concept of "turning waste into treasure," Kangqinfei designed and delivered a sodium chloride MVR evaporation crystallization system with a processing capacity of 3 tons/hour. This system employs mature mechanical vapor recompression (MVR) technology and precisely controls the crystallization characteristics of sodium chloride, successfully achieving the recovery of high-purity sodium chloride and near-zero wastewater discharge.

Based on a deep understanding of the characteristics of calcium chloride, Conqinphi designed and built a 2-ton/hour MVR forced circulation evaporation and concentration system for the client. This solution utilizes mechanical vapor recompression (MVR) technology as its core, combined with special anti-scaling and anti-corrosion designs, successfully concentrating the low-concentration calcium chloride solution to a high concentration, laying a solid foundation for subsequent resource utilization.

Addressing the client's pain points, Conqinphi customized a 2-ton/hour ammonium sulfate MVR evaporation crystallization system. The core of this solution is the use of MVR (Mechanical Vapor Recompression) technology, an advanced process, to achieve efficient, energy-saving, and environmentally friendly wastewater treatment and resource recovery.
