Drying VCM
Either sodium hydroxide briquette or potassium hydroxide briquette to remove water and hydrochloric acid from Vinyl Chloride Monomer VCM.
During the distillation of VCM, a part is dragged away with the residual hydrochloric acid. After neutralization with liquid caustic soda in a settling basin, the VCM is dryed and treated on a caustic soda bed to eliminate all traces of acids and water.
Use of soda briquettes or potash briquettes to dry VCM
