一． VOCs of Pharmaceutical Industry
1. Properties：
The pharmaceutical industry as fine chemical industry, has different kinds of products, complicated production procedure. During the production, it needs a big amount of rough material and organic solvent which generates a lot of VOCs.
2. Activated Carbon Adsorption：
Item | Solution | Technology | Type of VOCs | Type of AC |
1 | Solvent Recovery | AC adsorption—steam reactivation—Condensation Recovery | Benzene, methylbenzene, acetone, butanone, dichloromethane | EAC,GAC |
2 | AC Adsorption | AC adsorption—steam reactivation—incineration—emission | VOCs | EAC |
4 | AC Adsorption | AC adsorption—hot air reactivation—incineration-emission | VOCs | Honeycomb activated carbon |
二． Waste Water
三． The activated carbon, as the deep purification procedure of chemical waste water, could adsorb the organic compounds, color and heavy metal elements of the waste water which are not disposed by biological or chemical procedures.
Item | Solution | Technology | Waste water | Type of AC |
1 | AC adsorption | AC adsorption—reactivation—discharge | Chemical waste water | GAC & PAC |
四． Decoloration of pharmaceutical products
The decoloration of chemicals aims to improve the purity and quality of the products. The activated carbon has developed micro pores and mesoporous pores, which is the proper adsorption material of decoloration. For the decoloration of chemicals, the wooden-based powdered activated carbon is the widely used one.
