This fine chemical company, located in the Yangtze River Delta Chemical Industrial Park in China, primarily produces pharmaceutical intermediates and specialty acetate esters. During production, it generates approximately 140 tons of dilute acetic acid wastewater daily, with an acetic acid concentration of only 5% to 8%, making direct outsourcing treatment prohibitively costly.

The company's main business is the synthesis of sulfide dyes and organic intermediates. Its hydrogenation reduction and sulfidation reaction processes generate approximately 24 tons of low-concentration sodium hydrosulfide solution daily, with a concentration of only 8% to 12%. Direct transportation for disposal is costly and carries significant transportation risks. To achieve the resource recovery and reuse of sodium hydrosulfide and eliminate the potential for hydrogen sulfide emissions, the company commissioned the construction of a single-effect vacuum evaporation and concentration unit in 2025, with a processing capacity of one ton per hour.
