VOC Catalysts: The Green Guardian of the petrochemical industry

The petrochemical industry is one of the main sources of VOCs (volatile organic matter) emissions, and organic pollutants such as benzene series, olefins and alkanes produced in the production process pose a serious threat to the environment and human health. The promotion and application of VOC catalyst provides an efficient solution for pollution control in the industry.
In the petrochemical production process, VOCs mainly come from equipment leakage, process waste gas, storage and transportation losses. These pollutants not only cause photochemical smog and ozone pollution, but also cause damage to the human respiratory system and nervous system. The traditional treatment methods, such as adsorption and absorption, have some problems such as low efficiency and easy secondary pollution.
VOC catalysts convert organic pollutants into harmless carbon dioxide and water through the principle of catalytic oxidation. Its core is the active component of the catalyst, usually a precious metal or transition metal oxide. At the operating temperature of 200-400 ° C, VOCs molecules undergo oxidation reactions on the surface of the catalyst, and finally achieve complete decomposition. Taking a petrochemical enterprise as an example, after the use of VOC catalyst, the waste gas treatment efficiency increased from 75% to more than 98%, and the annual emission reduction of VOCs exceeded 500 tons.
VOC catalysts are widely used in the petrochemical industry, mainly covering the following scenarios: first, oil and gas recovery in the storage tank area, second, process waste gas treatment, and third, waste gas treatment in the sewage treatment station. In the specific application, it is necessary to select the appropriate catalyst type and process plan according to the parameters of waste gas composition, concentration, temperature and so on. A refinery adopts VOC catalyst to treat the exhaust gas of aromatics unit, which not only achieves the standard discharge, but also saves energy cost of about 2 million yuan per year through waste heat recovery.
The application of VOC catalyst has achieved remarkable results. Statistics from a petrochemical park show that after the use of VOC catalyst, the total VOCs emissions in the park decreased by 60%, and the surrounding air quality improved significantly. The operating cost of the enterprise has been reduced by more than 30%, and the win-win situation of environmental and economic benefits has been achieved.
