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 |
