Thank you very much for your hard effort and informtative video. I am recently working on JFGP PKG3 awarded to HDEC where the end user is Saudi Aramco for Jafurah utilites, Sulfur and interconnection system. The project mainly to treatment of SRU and TGTU for Sulphur exporting and gas sales. I found a lot of your information identical to what I am connect to as an entery level process engineer and that give more confidence to solid my understand.
Thank you for providing good knowledge about sru, can you explain about 3 catalytic reactors 1. Al and Tio, 2. Al 3. CO-MO what reaction they are promoting and what happens if reactors are not provided
Thank you for your great effort explaining all the intricacies of the process! I have a question if a trim air valve can only add more air for combustion to the burner (can the trim air valve also reduce the amount of combustion air to the burner?). Another question is if Sulphur rundown vessel is the same thing as Sulphur Trap? You also mentioned that ejector sweeps H2S from the Sulphur Rundown vessel with the HP steam. Where will it sweep this H2S to? To which vessel?
1. Trim air is for adjusting the combustion air requirements in case of increase or decrease in H2S conc. , in that case it will increase and decrease the air in order to maintain the tail gas ratio of 2:1 (H2S/SO2) 2. Sulphur run down vessel is the intermediate storage sump which has to be degassed before it is sent to storage tanks. Sulphur traps are the seal system which will prevent the Sulphur vapors from going into the rundown vessel in case of any pressure spikes in the upstream. These are of broadly 2 types. a) above ground b) below ground 3. The ejector air is either routed to incinerator or recycled back to reaction furnace inlet.
there are different configurations depending upon the conc. of H2S in the acid gas 50-100 mole% (rich feed) - straight-through configuration 20-50 mole% (lean feed) - split-flow configuration 10-20 mole% (lean feed) - split flow with preheating of the feed streams
it has an atmospheric vent , but the pit will be under negative pressure with the help of steam jet ejector, and discharge routed to the incinerator under running conditions. If the pit level is emptied out during shutdown, then the ejector can be stopped and during that time the pit will be under atmospheric pressure. If the ejector is out of service, the pit will not be swept out and H2S conc. will build up and pose an environmental risk.
