Recovery of Organic Solvents from Saline Wastewater in Fine Chemical Industry

Recovery of Organic Solvents from Saline Wastewater in Fine Chemical Industry

Evaporation and Crystallization of Salt-Containing Wastewater from the Chemical Industry

● Industry: Fine Chemicals

● Concentration of wastewater containing 7-10% isobutanol and 0.5% sodium chloride

● Evaporation medium: Isobutanol

Runner-up Plan: MVR-600

● Distillation column, falling-film reboiler, single-stage compressor.

● Processing capacity: 4 t/h, evaporation rate: 600 kg/h

● After MVR evaporation, the distillate at the top of the tower contains 60% isobutanol, and the residual isobutanol at the bottom of the tower is less than 0.2%.

Operating energy consumption

● The compressor consumes 18 kW of electricity during operation, while the circulating pump and other pumps consume 5 kW.

● Steam consumption: 20 kg/h
