Vertical gas scrubber for treatment of odor nuisance in medical sector

The problem

Our client is active in the medical sector. They were looking for a solution for the odor nuisance caused by the activities in their company, more specifically the odor nuisance around their water treatment plant and sludge tanks. Mercaptans and H2S were present in the polluted airflow. H2S is a poisonous gas with a strong odor, similar to the smell of rotten eggs. Mercaptans are also toxic and have a strong odor even at low concentrations. The aim of the installation was therefore to reduce the pollution in the airflow in such a way that the odor nuisance were reduced to a minimum.

Our solution

PCA Air opted for a vertical chemical scrubber. Gas scrubbers neutralize harmful components in air or exhaust streams. Due to intensive contact between an air stream and a liquid such as water, certain gaseous components dissolve in the water. By then dosing the right chemicals to the wash water, the absorbed pollution is converted into, for example, a soluble salt. This promotes absorption into the wash water. A gas scrubber is therefore the perfect solution for our customer's problem. With this customer, the aim was therefore to remove as many chemical components as possible from the polluted airflow. To achieve the highest possible efficiency, we used different chemicals. By using a recirculation pump, partially polluted water is reused, saving the customer a lot of water. This project was realized in a time span of 5 weeks after reception of the request of the customer.
