Sinopec VOCs waste gas treatment technology is internationally advanced

A deep purification technology of volatile organic compounds (VOCs) waste gas in the petrochemical industry that has reached the international advanced level was successfully developed by Sinopec Fushun Petrochemical Research Institute and successfully passed the technical appraisal
organized by the China Petroleum and Chemical Industry Federation in Beijing.
The gas purified by this technology, benzene, toluene, xylene, acetaldehyde, non-methane total hydrocarbons, etc.
meet China's "Comprehensive Emission Standard for Air Pollutants" (GB16297-1996), and the concentration of non-methane total hydrocarbons is less than 30 mg/cubic meter, realizing the deep purification treatment
of VOCs exhaust gas.

This technology is aimed at the deep purification treatment of VOCs waste gas, on the basis of technological innovation in the main aspects of process flow, supporting catalysts and key equipment, for different VOCs waste gas development petrochemical sewage treatment plant exhaust gas desulfurization and total hydrocarbon concentration homogenization - catalytic oxidation, polyester waste gas absorption and total hydrocarbon concentration homogenization - catalytic oxidation, thermoplastic styrene-butadiene rubber production tail gas condensation - mist removal - catalytic oxidation, propylene oxide/styrene (PO/ SM) waste gas double series catalytic oxidation and other four typical petrochemical industry waste gas deep purification treatment processes
.
Applying this technology, researchers have also developed four typical VOCs waste gas catalytic oxidation catalysts such as honeycomb WSH-1, HBFW-1, WSH-1F, WSH-2, etc.
, and reagents
with dual functions of desulfurization and concentration homogenization.
At the same time, based on this technology, a combined gas-to-gas heat exchanger and a large square catalytic oxidation reactor with heat pipe and finned tube with high heat recovery rate and wide applicable temperature range
have been developed.

The technology has applied for 50 patents (33 authorized).

Based on this technology, the refinery wastewater treatment plant exhaust gas, PO/SM exhaust gas and rubber exhaust gas treatment technology has reached the international leading level
.
Today, a total of 14 sets of catalytic oxidation treatment plants for refinery sewage treatment plants, including waste gas, polyester waste gas, rubber exhaust gas and PO/SM tail gas, have been built using this treatment technology, with a cumulative treatment of more than 4.
04 billion cubic meters of waste gas and a reduction of more than
12,500 tons of VOCs pollutants.
