A vacuum distillation process for separation of antimony trisulfide and lead sulfide from jamesonite

Key words：Atmospheric and vacuum; distillation; process; pollution Abstract：The atmospheric and vacuum distillation unit was analysed on the device's size, composition, technical route and process. The results show that the flue gas produced by atmospheric and vacuum furnace is the main emission source, and the main pollutants in the flue gas are SO2, NOX and soot. The wastewater pollution is mainly electric desalting salt water, and it was treated in saline wastewater treatment plant in the factory.

Washing Process

Polymerizable C9 fraction was cut by atmospheric distillation of raw C9 fraction from thermal cracking. The obtained fraction polymerized using boron trifluoride ethyl ether as catalyst and then the polymerized mixture was washed by warm 10%wt Na2CO3 aqueous solution and distilled water and separated by vacuum distillation for producing light colored C9 petroleum resins with high softening point. The suitable conditions for polymerization process, washing process, vacuum distillation process were investigated to improve the C9 petroleum resins production. Under these conditions, the petroleum resins product with Gardner color index of 4-5 and softening point of 102-120°C could be obtained.
