Volatile organic compounds (VOCs) Treatment

Adsorption Technique for Gas Purification

With the widespread use of chemical products in the industry, more and more organic pollutants enter the atmosphere, mainly low-boiling, volatile organic compounds(VOCs). These gases enter the atmosphere and can cause irritation to the human eye, nose and respiratory system, and damage to the internal organs.


At present, the more mature methods for treating VOC gas are adsorption, desorption, and catalytic combustion. The method has high purification efficiency, simple operation and wide application range.

Sunresin has exploited the resin for Separation and recycling of low and medium VOCs, including: alkanes, halogenated hydrocarbons, aromatic hydrocarbons, low-carbon alcohols, ketones , esters,and other organic matters.

Resin adsorption technology for VOCs treatment:
The waste gas resin adsorption technology is mainly used for non-polar or weakly polar volatile organic molecules. It adopts a specifically researched and developed macroporous polymer adsorption resin with uniform pore size, high specific surface area and high strength. By utilizing the non-polar adsorption and intermolecular forces between the internal skeleton molecules of the resin and the volatile organic molecules, the adsorption resin performs highly selective adsorption on the non-polar and weakly polar molecular groups in the waste gas, in order to achieve the purpose of precise adsorption and gas emission compliances.
Advantages of resin adsorption in VOCs treatment compared to traditional adsorption techniques:
Flexibility: adaptation to different industries and different systems from small equipment, skid-mounted equipment, to waste gas treatment system. Flexible cooperation to meet emission requirements.
Strength: regular spherical particles with acid, alkali and high-temperature resistance, over 2000 regeneration cycles.
Purity: Synthetic styrene structure that has no metal impurities, preventing catalytic polymerization or combustion of unsaturated organics in pores.
Efficacy: Over 99.5% removal rate for non-polar and weakly polar VOCs, for emission compliance.
Security: Good hydrophobicity. Thanks to its own water content, no need for dry adsorption, avoiding sustained heating due to adsorption exotherm.
Sustainability: Longer life cycle, no need for overall replacement, no solid waste generation. Annual replenish around 5%.
Type of volatile gases suitable for resin adsorption technology:
The resin adsorption technology is suitable for most non-polar solvent, including alkanes, alcohol ethers, chlorinated hydrocarbons, ketones, aromatic hydrocarbons, esters, and organic amines.
Industries that may benefit from resin adsorption for VOCs treatment:
1.Pharmaceutical Chemicals
2.Pharmaceutical preparations
3.Pesticide synthesis
4.Tail gas from H2O2 production
5.Chloride Industry
6.Large Chemical Industry
In addition to meeting emission requirements, resin adsorption also realizes the efficient recovery of organic volatiles in the waste gas, and has a recovery rate of over 99%.
Typical Application for VOCs Treatment
  • N-hexane,heptane,cyclohexane
  • Trichloroethylene,trichloroethane,dichloromethane
  • Trichloromethane,chlorobenzene
  • Benzene,toluene,xylene
  • Isopropanol,butanol
  • Acetone,butanone,methyl isobutanone,cyclohexanone
  • Ethyl acetate,butyl acetate,acetate
