“With the official operation of the condensate recovery system, 21.9 tons of condensate can be recovered per hour, with an estimated annual recovery volume of around 191,800 tons. ”On November 27, Niu Jimin, deputy director of the Public Utilities Department at Jinzhou Petrochemical, explained to the reporters.   Energy conservation and emission reduction are important ways for enterprises to reduce costs and increase efficiency. Jinzhou Petrochemical focuses on addressing issues at the source and implementing strict process controls, making continuous efforts in its transition toward a green and low-carbon development model. It takes various measures to adopt an energy-saving and carbon-reduction \"green\" approach, striving to be a pioneer in energy and water conservation within its industry and sector.   During production operations and winter anti-freezing periods at Jinzhou Petrochemical, some pipelines are heated using steam, which results in the generation of large amounts of condensate water. As this condensate water is distributed in various locations, it is difficult to collect it. For a long time, this water has been discharged directly, leading to waste of resources.   To address this issue, Jinzhou Petrochemical took advantage of the downtime period during the 2024 major maintenance to implement a condensate recovery project. It installed new condensate recovery pipelines and other facilities, as well as 43 sets of condensate recovery manifolds and 5 units of condensate recovery skid-mounted equipment, in order to recover the condensate generated by all the steam tracing pipelines within the plant. The recovered condensate is used as company-grade deionized water, circulating water, and water for production in certain facilities, thereby achieving energy and water savings.   In the construction of condensate recovery system projects, the modular condensate recovery equipment uses the system purification air as the power source to transport the recovered condensate. To prevent condensed water from flowing back into the air handling system, technicians from the Public Utilities Department of Jinzhou Petrochemical have repeatedly worked with designers and others to develop design plans and instrument control schemes for the condensed water recovery skid-mounted equipment. During the commissioning process, the Utility Department organizes training for relevant personnel to ensure a smooth commissioning. At present, all 5 condensate recovery skid units at Jinzhou Petrochemical have been put into operation, and the \"little white dragons\" in the system’s pipeline network have completely disappeared this winter.   Next, Jinzhou Petrochemical will continue to advance its green and low-carbon development strategy. While ensuring the stable operation of its production facilities, it will keep working on reprocessing contaminated oil in order to reduce the amount of such oil stored in tanks ； Optimize energy-saving measures such as the renovation of low-temperature heating systems to further reduce steam consumption and accelerate the pace of green and low-carbon transformation.
