VOC is an organic solvents used in chemical, pharmaceutical and many other industries. Direct release of VOC to the atmosphere seriously pollutes the environment, impedes the growth of plants and animals and endangers human health. Green Chemical Technique (VOCEA technique) makes VOC harmless and ready to be re-used.
Applied Fields
Chemical, pharmaceutical, oil, petrochemicals, rubber, plastics, synthetic fibers, agricultural chemicals, painting, electrical, electronic components, printing, photographic materials, artificial leather, dry cleaning, etc.
Applied Chemical Types
Hydrocarbons, halogenated hydrocarbons, aldehydes and ketones,esters, ethers, alcohol, the polymer monomer, etc. used in almost all organic matters.
"New technique treating waste gas and waste liquid with VOC" (VOCEA technique) is an critical technical breakthrough of GunnerYS to reslove VOC related problems. The technique was conducted using a special screening, synthesis, compound of the absorbent process in one laboratory in US. After that,repeating tests were conducted and confirmed in Singapore. Finally, large scale applications were carried out at plants in both China and abroad, which proves it a mature technique.
At present, the largest diameter of the equipment that built with VOCEA to treat waste gas and liquid is 4.8 meters; the largest gasprocessing capacity is 120,000 cubic meters/hour; the largest waste handling capacity is 20 cubic meters/hour.
VOCEA technique effectively solved the long-standing VOC related problems that have troubled domestic enterprises. At the same time, the technique commendably recycles the waste gas (recycled VOC can be reused), therefore bringing significant environmental, social and econnomic benefits to our customers.

Technial characteristics of VOCEA
1. The technique uses special high efficient absorbent that has high thermal stability, good selectivity,high absorption rate, minor losses, no second time pollution to the environment and recyclable; the absorbent also has excellent re-design performance; different functions can be achieved to treat waste gas or liquid through different molecular design.
2. The investment and the operation costs are low.
3. The process uses automatic controls; the equipments are easy to operate and maintain.
4. The technique uses proprietary and high-performance micro gas-liquid contactor that makes it lighter and more efficient.
5. The technique uses proprietary high-performance gas stripping equipments; therefore VOC in waste liquid can be removed, collected and recovered.
6. The equipments last long and have good safety performance; therefore they can be used in explosion-proof sites.
To sum up,VOCEA technique and related set of equipment can completely get rid of VOC without second time pollution;therefore it particularly meets the requirements of current promotion of clean technology and sustainable development. The technique is becoming widely recognized and accepted. |
