Research Progress of VOCs Emission Accounting Method for Storage Tanks in Petrochemical Enterprises

摘要

In consideration of Chinese policy on comprehensive regulation of volatile organic compounds (VOCs) and sewage charges, several methods for quantitative calculation of respiratory loss in crude oil tanks are analyzed and compared to evaluate the VOCs emission of petrochemical enterprises reasonably, including United States Environmental Protection Agency (EPA) recommended method, Petroleum depot energy saving design guidelines recommended method, emission coefficient method, Loss of liquid petroleum products in bulk estimation method and Technical guidelines for the preparation of emission inventories of atmospheric volatile organic compounds (Trial) recommended method. According to the production situation of petrochemical enterprises in China, selecting the appropriate calculation method, thus providing basis for VOCs source accounting, regional environmental planning and environmental monitoring for production and management departments.
