Waste emissions during the propylene oxide production process
Thread Content
Does anyone know the specific amounts of waste generated and the corresponding emission standards for the three types of waste in the process of producing propylene oxide through high-temperature chlorination? ?
Wastewater discharge from 50,000-ton chlorohydrin process propylene oxide plant
Project | Water volume (tons/year) | Pollutant concentration (mg/l)
Plant wastewater | 2,228,400 | COD: 2000, BOD: 1000, SS: 1000, Cl-: 40,000
Recirculated water discharge | 72,000 |
Domestic wastewater | 2,160 |
Washing wastewater | 5,760 |
Note: Designed annual operating hours: 7,200 hours.

With so much sewage, how can it be dealt with? Is there any good way? Please advise, experts:
Saponification wastewater can be electrolyzed to produce alkali for reuse
What is the approximate amount of waste gas and waste residue? Thank you
