After nearly half a month of efforts of the First Oil Plant of Fushun Petrochemical Company, the DH-3000 dryer imported from the United States Hankson Company settled into the pipe network air pressure system of the New District Oil Plant. At present, all the operational indicators have reached the design requirements and the results are good. The smooth investment of new equipment has not only laid a solid foundation for the supply of power in the new area of ​​the No.1 Oil Plant, but also ensured safe production in the winter, and at the same time, the energy consumption has been greatly reduced, and the environmental protection has also been guaranteed.
