Pulp and paper manufacturing
Air Filtration
Pulp and paper operations present multiple challenges for air pollution control. It causes gaseous contamination during the pulping process. The most important gas emission is water vapours. Additionally, particulates, nitrogen oxides, volatile organic compounds (VOCs), sulphur oxides and total reduced sulphur compounds (TRS). The sulphur compounds such as methyl mercaptan, dimethyl sulphide, and particulate matter SO2 and NOx present in the gases emitted by different process units causes high odours and hence pulp and paper operations are considered as one of the highly polluting industries in the world.
Aqoza’s Air filters work effectively for the paper and pulp industry by removing harmful gases with molecular filtration. The advanced filtration techniques used in the air filters and the filtration media like catalytic activated carbon media, impregnated activated carbon etc are durable and effective, delivering optimal results and cost- savings solutions in the paper mill environment.
Odour Control
There are three general groups of odor-producing compounds that come from pulp and paper industries that cause nuisance odour during the process. The smelly chemicals are reduced sulphides, ammonia, and other organic compounds. These compounds have the characteristic pungent odor of rotten eggs and rotten cabbage
Aqoza odour control solutions help paper and pulp industry clients to solve complex odour issues by adsorbing and neutralizing the odors associated with the paper and pulp industry.
Corrosion Control
The working of paper and pulp industries emit contaminants and high humidity gases while taking the pulp out of wood and creating paper. It involves several complex stages and the chemical treatment of raw materials. These processes produce gases that have the potential to cause corrosive damage to the machineries, equipment and other electronic process control systems.
Aqoza’s corrosion control equipment offers self-contained, air scrubbing systems designed to provide recirculated air, free of corrosive gases. It also pressurizes the space to prevent infiltration of contaminated corrosion causing elements and helps the paper mill environment from endangering the operation of its machineries and other electronic devices.
