Recovery of solvents and chemicals

The demands for recovery of useful solvents and other chemicals from the waste continue to increase in order to meet environmental regulations and reuse recovered solvents and chemicals to reduce operating cost. AMT PACIFIC can provide innovative solutions to waste treatment problems using the advanced separation technologies;

• Distillation/ Azeotropic Distillation
• Extractive Distillation
• Liquid-Liquid Extraction
• Extraction/Distillation Systems
• Absorber/Stripper Systems
• Adsorption

Applications

• Recovery of solvents from a large-volume of vent gas containing thin solvents
• Recovery of Carboxylic Acids from waste water formed in the DMT, PTA, paper and pulp, and other chemical plants.
• Aromatic recovered from refinery and petrochemical plants.
• Useful Gas recovered from vent gas
• Alcohols recovered from waste water.
  • Primary, Secondary & Tertiary Buthyl Alcohol and Ethanol, Methanol, IPA, Butanol etc..

Solvent Recovery From Waste Gas

AMT PACIFIC's solvent recovery process is based on an activated carbon adsorption method which recovers solvents from a large-valume of vent gas containing thin solvents This process treats such solvents as THF, Ketone and Anone without degrading or polymerizing. The recovered solvent is perfectly celaimed, and identical to fresh solvent. Costs for solvents can be remarkably reduced, and at the same time, pollution control can be achieved completely.

Methyl Acetate Hydrolysis Plant

Methyl Acetate(MA) is generated during oxidation of PX with solvent(Acetic Acid) in PTA plant. MA can be recovered by concentrating of waste water and this MeAc is raw material of this plant, AMTP's MA Hydrolysis process produces Acetic Acid, Methanol and water mixture with high yield and efficiency. Acetic Acid & MeOH separation tower can be added by customer's need.

This process has already been proven in commercial operation and is getting good reputation from PTA makers who get MA as a by product.

Sec-Buthyl Alcohol(SBA) Recovery

Highly nonideal solutions like this SBA and water mixture can be separated by azeotropic distillation technology with entrainers.
