Jiujiang Petrochemical Achieves Significant Results in Winter Energy Conservation Management 2016-12-23 Source: Sinopec News Network Since the onset of winter, Jiujiang Petrochemical has focused on preventing freezing and condensation as well as on energy conservation and consumption reduction, strengthening on-site management through frequent inspections, adjustments, and optimizations, thereby achieving notable results in both preventing freezing and saving energy. Strengthen on-site inspections to reduce unnecessary consumption. The main method for preventing freezing and condensation in the device is steam tracing, but the amount of steam supplied, and whether it varies with temperature, have a significant impact on energy consumption. To urge various units to carry out regular and thorough adjustments, and to prevent energy losses caused by excessive steam supply as well as leaks, the company’s energy conservation officers conduct unannounced inspections on a weekly basis of the anti-freezing and anti-condensation measures in place at these units, as well as the energy conservation practices on site. Any issues identified are reported promptly, and actions are taken to address them, ensuring that the anti-freezing and anti-condensation measures are properly implemented. Strengthen the implementation of responsibilities and ensure frequent inspections and adjustments. In accordance with the company’s arrangements for ensuring safe production during winter and the relevant regulatory requirements, each production and operation unit formulates anti-freezing and anti-condensation plans, specifying the key points, contents of inspections, as well as the responsible persons for these tasks. Anti-freezing and anti-condensation records are kept, and these are incorporated into the shift handover procedures. Based on the operation of the equipment and changes in temperature, each unit assigned dedicated personnel to adjust the opening degrees of the heating steam valves for the various devices in a timely manner. This was done to minimize steam consumption while ensuring that no condensation occurred in the pipelines; as a result, the steam consumption was reduced from 14 tons per hour to 9.5 tons per hour. Optimize system operation to achieve energy savings and reduced consumption. On the basis of ensuring effective frost and condensation prevention, the company has further improved the optimal operation of its various production units. Special attention has been paid to adjusting the operation of water-cooling and air-cooling systems; as a result, 60 air coolers and fans were shut down, resulting in a power savings of 2,500 kWh per hour, as well as a reduction in the plant’s circulating water consumption by 3,200 tons per hour.
