Waste from the 500,000-ton vinyl acetate project and the 100,000-ton polyvinyl alcohol project
Thread Content
What are the emissions of waste water, waste gas, and solid waste for the 500,000-ton vinyl acetate project and the 100,000-ton polyvinyl alcohol project? What are the levels of the main components in waste emissions (such as SO2 in exhaust gases, COD in wastewater, etc.)? Answerer, I’ll give you extra points! 3q
500,000 tons of vinyl acetate? Really?
What is the type of polyvinyl alcohol? Is it of low polymerization degree?
I would also like to know that since there are no such large-scale projects in China at the moment, the poster must have chosen the ethylene method; I’m also interested in knowing about the varieties of polyvinyl alcohol.
Waste generation for 100,000 tons of vinyl acetate (calcium carbide process, including boiler exhaust gases): 6. Major waste outputs: 6.1 Wastewater: t/h – 16; 6.2 Waste residue: 10,000 tons/year – 11.2; 6.3 Exhaust gases: 10,000 Nm3/h – 17.5. For the polyvinyl alcohol production plant with a capacity of 55,000 tons per year: Exhaust gases: m3/h – 190,000; Wastewater: m3/h – 500; Waste residue: t/day – 162.8. Most of this waste residue is slag. You can calculate the required scale on your own – what’s the practical sense in going for such a large scale? Is it perhaps a plan for 10 years from now?

Excuse me, experts – what is the situation regarding the capacity expansion of domestic polyvinyl alcohol manufacturers?
I’m looking for someone who has detailed information on a 100,000-ton vinyl acetate production project. I’d like it, thank you. Ah, that person has it – please send it to me. My email address is yepengting2005@126.com
7# Smithlee: 500,000 tons. It’s not available in China at the moment; I think only Global has this manufacturing process
