Hi. Currently, we have a problem in our hydrogen supply. With this, hydrotreating unit was shutdown. The problem is we have already reached low pressure for the compressor that is why we cannot further cool the temperature in the reactors. High temperature in the reactor at 200 deg c in our case, with hydrogen atmosphere will lead to catalyst reduction. Compressor cannot be started due to its permissive suction pressure and nitrogen pressure is lower than this permissive suction pressure. We have already depressurized the reaction section and put the catalyst under nitrogen atmosphere with around 3% hydrogen but there are beds in the reactors which are still at 260deg c which is bad. Does this mean that the catalyst will be reduced already? Please help.
