1) In plants where main gas is N2, you cannot run B.E as N2 is circulated through air compressor
2) In plants where DS gas is used, you can run by taking precautions like HTS out CO slip should be in control range to keep methanator temperatures within limits. For this low, FE load and high S/C is recommended
3) For format formation as said by Satyajit, process gas is already venting at methanator downstream because we require sny gas/H2 for reduction which means CO2 removal system is already online at low load. But with increase of load, CO to absorber will also increase

I think flow/pressure indications going to deviation meter to be verified
