【Haichuan Chemical Salary News】Guangzhou Petrochemical’s SZorb unit records new high in production volume and new low in energy consumption

Thread Content

The SZorb (catalytic gasoline adsorption desulfurization) unit at Guangzhou Petrochemical closely aligns with the company’s production plans, making an increase in gasoline production its top priority. While ensuring safe, environmentally friendly, and stable operation of the unit, continuous optimizations are carried out. From January to October, this unit produced nearly 1.28 million tons of gasoline, reaching a record high in terms of output； At the same time, energy consumption, adsorbent usage, and actual environmental emission levels have reached record lows. The S Zorb unit is focused on delivering benefits, closely aligning with the company’s efforts to save energy, reduce consumption, and improve efficiency. It continuously optimizes the production process to minimize processing losses and ensure long-term operation of the unit. From January to October this year, despite record levels of total processing volume and gasoline production, the energy consumption of the facilities decreased by 15% on a year-on-year basis, while the consumption of adsorbents dropped by nearly 50%, reaching a historic low. To ensure the stable operation of the equipment under high loads, process engineers continuously optimize the production processes, keep a close eye on changes in the properties of the raw materials, adjust the volume of air used for regeneration by focusing on the activity of the adsorbents, and address any issues that could affect product quality in order to maintain the quality of gasoline ； Equipment personnel remain on site to provide continuous monitoring of the equipment, ensuring the safe and stable operation of the unit ； The team members conduct thorough inspections and operate with care, identifying and addressing potential hazards in a timely manner to ensure the safe and stable operation of the equipment. While increasing gasoline production, the S Zorb system places great emphasis on environmental protection to ensure that emissions meet the required environmental standards. Since the second half of this year, the sulfur content in the crude oil used by Guangzhou Petrochemical has remained high. Faced with the dual pressures of ensuring product quality and protecting the environment, the technicians working on the SZorb unit have worked hard to overcome these challenges and carry out optimizations and adjustments. By adjusting the volume of recycled air and the alkali washing unit, as well as by strengthening the monitoring of key operational parameters, the sulfur dioxide emissions from the facility are kept within the strictest allowable limits.
