Industry Status and Challenges


Driven by the dual forces of the “dual carbon” goals and increasingly stringent environmental regulations, the chemical industry is undergoing a profound green transformation.
(1) Enterprises are facing significant pressures from the challenges of treating high-salt and high-COD wastewater, high costs for hazardous waste disposal, and volatile raw material costs.
(2) The traditional end-of-pipe management model has become unsustainable, and the industry urgently needs to shift—from “waste treatment” to “resource utilization”—by upgrading its technologies and turning byproducts generated during the production process into valuable assets.

Evaporation Crystallization Solution


1. Resource Recovery and Zero Liquid Discharge (ZLD) of High-Salinity Wastewater

▪ Application scenario: High-salinity wastewater generated during chemical production (containing sodium chloride, sodium sulfate, etc.).

▪ Technical Solution: The “salt separation and crystallization” process is adopted, combining membrane concentration with MVR (mechanical vapor recompression) technology.

▪ Core Value: Precisely separate mixed salts to produce high-purity, industrial-grade salt that can be directly sold or reused; achieve compliant reuse of wastewater, significantly reducing discharge fees and hazardous waste disposal costs, and helping enterprises attain their zero-emission goals.

▪ The process achieves energy savings of 40% to 70%, significantly reducing energy consumption.

 

2. Fine Preparation of Inorganic Salts

▪ Application scenarios: Production and purification of inorganic salts such as sodium sulfate and ammonium chloride.

▪ Technical Solution: Optimize the crystal growth environment by precisely controlling supersaturation.

▪ Core value: Address the issues of low efficiency and uneven particle size distribution inherent in traditional batch production, yielding high-quality crystal products with uniform particle size and excellent flowability, thereby enhancing market competitiveness.
