    On January 10, the project "New Technology for High-precision Removal of Sulfur Dioxide (SO₂) Adsorption Method in Liquid Phase Hydrocarbons" jointly developed by Yan'an Petrochemical Plant, Beijing Petrochemical Engineering Co.
    , Ltd.
    and China University of Petroleum (Beijing), which is affiliated to Yanchang Petroleum (Group) Refining and Chemical Company, passed the appraisal
    of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation.

    The appraisal committee headed by Xu Chunming, academician of the Chinese Academy of Sciences, unanimously agreed that this technology fills the technical gap of high-precision adsorption and removal of sulfur dioxide in liquid isobutane at home and abroad, ranking the international advanced level
    .

    The project was industrialized in November 2019 on the 300,000 tons/year propane/isobutane mixed dehydrogenation unit in the light hydrocarbon center of Yan'an Petrochemical Plant, which became the world's first industrial unit
    for high-precision sulfur dioxide removal by adsorption of liquid phase carbon IV.
    This technology can remove the sulfur dioxide content of alkylated C4 in the mixed dehydrogenation feed from 400ppm to less than 1ppm, and can be applied to the high-precision removal of sulfur dioxide in liquid hydrocarbons, including the removal of sulfur dioxide in alkylated liquid phase C4 and sulfur dioxide removal in liquefied gas
    .

    During the operation of the propane/isobutane hybrid dehydrogenation unit, the plant solved the problems of fluctuation of incoming sulfur content caused by insufficient alkylated carbon IV raw materials and supplementation of isobutane, resulting in fluctuations in the operation of sulfur dioxide adsorbent unit and changes in the regeneration cycle of adsorbent, realized high-precision removal of sulfur dioxide in alkylated carbon IV, protected the mixed dehydrogenation precious metal platinum catalyst, and realized the continuous and stable long-cycle operation
    of the hybrid dehydrogenation unit.
