  • What are the ways or methods to ensure that sulphiding of the Diesel and VGO hydrotreater units catalyst is completed? What are the check points?

    1. Is it purely by injecting the stoichiometric required DMDS into the reactor that decides sulphiding is completed?

    2. Is there any thumb rule for quantity of dmds that needs to be dosed during first stage of sulphiding at 220degC or quantity of dmds that needs to be injected for second stage of sulphiding at 330degC?
