　　According to Sinochem News, recently the Ethylene Department of Fushun Petrochemical Company carried out optimization work on the heat source of the reboiler in the propane removal tower of the gas fractionation unit, replacing steam with hot water; this measure is expected to save around 10 million yuan in production costs each year. 　　Previously, the depropanization column in the gas fractionation unit was heated using steam, resulting in relatively high energy consumption costs. To reduce costs and improve energy efficiency, the Ethylene Department of Fushun Petrochemical Company relied on lean management to actively seek ways to optimize energy use. After thorough research and evaluation, it decided to adopt a technical solution that utilizes the hot water from the nearby No. 2 Oil Plant as an alternative heat source. During the renovation process, the department organized things meticulously and carried out the work steadily to ensure the successful commissioning of the project. 　　At present, the device is operating smoothly, with all process parameters meeting the required standards. It is able to reduce steam consumption by 7 tons per hour; based on the device’s annual operating time, it is estimated that production costs can be saved by around 10 million yuan per year, resulting in significant direct economic benefits.
