New process for VOCs removal in production of micro-suspension paste resin
The content of total non-methane hydrocarbons(VOCs)in the tail gas discharged after the unre-acted residual vinyl chloride monomer in PVC paste resin latex is recycled by self-pressure and vacuum re-covery and then through spray drying exceeds the national standard emission limits.The existing domestic and foreign waste gas treatment methods not only have high operating costs but also pose relatively large safety risks.Therefore,a new process suitable for VOCs removal during the production of micro-suspension paste resin has been developed to meet the national standard emission limits for VOCs.
