Application Cases

Project Background This agrochemical company is constructing a new 30,000-ton/year pyraclostrobin project, producing 8 tons/hour of saline wastewater as a byproduct. The wastewater composition is: Na₂SO₄ 15%, NaCl 12%, CODcr 800 mg/L.

In the pigment chemical industry, the treatment of saline wastewater has always been a crucial aspect of environmental protection and resource recycling for enterprises. A well-known pigment chemical company, specializing in the production of high-end organic pigments such as azo and phthalocyanine pigments, has an annual production capacity of 30,000 tons. During its production process, it generates a large amount of sodium chloride wastewater daily, with concentrations fluctuating between 8% and 15%.

Based on steam price of 180 yuan/t and electricity price of 0.65 yuan/kWh, the four-effect compressor saves approximately 11 million yuan annually in steam costs; resource utilization of miscellaneous salts generates an additional 9 million yuan annually. Carbon reduction per ton of water is 0.32tCO₂, resulting in a total annual emission reduction of 48,000 tons.

The 10t/h sodium sulfate and lithium sulfate MVR evaporation crystallization system is another milestone for our company in the field of "zero discharge" of high-salt waste liquid in rare earth functional materials.
