Relevant analyses or calculations have been performed for safety restriction orifices under conditions of control valve failure, thermal expansion, and emergency overpressure relief. Through calculation and analysis, safety restriction orifices can play an important role in reducing safety valve discharge, lowering pressure drop in control valves, and reducing the risk of pressure relief, thereby achieving energy conservation and emission reduction, cost savings and investment reduction.

Fragility curves carry significant implications for post-earthquake structural evaluation and provide design guidance for structural design of new construction. Fragility curves have been extensively studied for building and bridge structures, whereas research on fragility curves remains notably scarce in the petrochemical sector. In this paper, a 120m height reinforced concrete chimney was selected to conduct the nonlinear response history analysis. And 15 strong ground motion records from the Pacific Earthquake Engineering Research Center (PEER) worldwide were selected, and scaled to six seismic excitation levels. Then the incremental dynamic analysis method was adopted to get the fragility curves for the RC chimneys, providing a theoretical basis and data support for post-earthquake evaluation of reinforced concrete chimneys.

The compilation of VOCs emission inventories for petrochemical enterprises is of great significance for VOCs emission control. Taking a certain petrochemical enterprise in China as an example, this paper adopted the source classification and calculation methods recommended by the state to calculate the VOCs emission in 2020. Then the emission inventory was compiled, and the emission levels and characteristics were analyzed. The results indicated that the total VOCS emission of the plant was 4230 tons, which mainly contributed by tanks (32.9%) and loading (32.2%). The total VOCS emission factor of this plant was 0.35 kg VOCS /t oil refined, and VOCS emission factors of tanks and loading were 0.034 kg VOCS /t turnover and 0.14 kg VOCS /t turnover respectively, which were quite low among petrochemical plants. The research results provide reference for the study and emission control of VOCS in China's petrochemical enterprises.

This study discusses the treatment technologies and principles for volatile organic compounds (VOCS) and benzene homologues emitted during the loading of gasoline, naphtha and jet fuel at a petrochemical terminal. The operational effectiveness of a combined "low-temperature catalytic oxidation" process in treating VOCS and benzene series from dock loading operations is presented. Results demonstrate that hydrocarbons, benzene homologues and other VOCS achieve compliant emissions after treatment through this process. By implementing sealing modification to vessel vapor recovery systems and upgrading inerting system maintenance to reduce oxygen content in loading vapors, the safe operation of ship-to-shore docking systems during loading operations can be ensured. This study provides a reference for VOCS emission control in terminal loading operations.

In the production process of petrochemical catalysts, extensive pneumatic conveying drying systems are employed for drying catalyst powders. Conventional dust collection technologies – including bag dust collectors, cyclone dust collectors and spray scrubbers – exhibit low interception efficiency for catalyst particles. Significant quantities of catalysts are consequently released into the atmosphere or absorbed into spray water systems, resulting in both economic losses and environmental contamination. Gas purification membrane technology is a new type of gas-solid separation technology. The double-layer composite structure of the membrane material can intercept catalyst particles on the surface of the membrane, maintain high interception efficiency, reduce the operating resistance of dust collectors and reduce operating energy consumption. It is of great significance for reducing pollution and carbon emissions in the production process of petrochemical catalysts.
