Study on producing an material voc absorption and odor control in the painting industry
Abstract
The method of capturing and processing VOCs is the key to protecting the ecological environment, improving human health and achieving sustainable development. Currently, there are two ways to process VOCs: destruction and recovery techniques. Destruction techniques mainly include thermal or catalytic oxidation, biological degradation, and plasma methods. These technologies convert VOCs into carbon dioxide and water, mainly through physical or chemical reactions. Recovery techniques include absorption, adsorption, and condensation. These methods enrich or separate VOCs through physical or chemical means. Absorption is widely used worldwide due to its simplicity, safety, recyclability, low energy consumption, and competitive pricing. However, the most important thing in the absorption process is to choose the most suitable absorbent to treat VOCs. The solutions used to remove VOCs include water, alcohol and ketones or less volatile hydrocarbons. However, these absorbents have many disadvantages such as low absorption capacity, poor recyclability, high corrosiveness, and a tendency to cause secondary pollution. This article presents research results on the development of oil-in-water emulsion systems for VOC absorption and odor control in the paint industry.
