    Petcoke Gasification Refractory Reliability

    Limestone as CaCO3 and Fly ash (Coal Fly ash) are used as flux in Petcoke(High Vanadium content) Gasification unit under reducing atomsphere to minimise fusion temperature of petcoke. The fusion temperature is important as it affect the refractory life. Petcoke quality remains more or less...

    Replacement of wash water with hydrocarbon at Upstream of Coker fractionator overhead condenser

    Thanks for your prompt feedback. If the fractionator overhead has sufficient water in form of steam along with hydrocarbon then is there any feasibility as partial pressure of H2O will remain same after mixing that means 10 % water vapour already will remain in the overhead stream? (as velocity...

    Replacement of wash water with hydrocarbon at Upstream of Coker fractionator overhead condenser

    Normally wash water is used to wash ammonium and cynaide salts in overhead vapour line (upstream of condenser) in Delayed coker fractionator.Is it technically feasible /viable to replace this stream with hydrocarbon instead of water.

    HP Steam Superheater Performance in Sulfur unit

    Maldistribution of reactor product stream is not likely cause because ,flow is evenly distributed in all three incinerators and floated with the stack back pressure.Train 3 incinerator blower is running at full capacity of its design as compare to other two trains, however, we will cross verify...

    HP Steam Superheater Performance in Sulfur unit

    Excess oxygen is maintained more than 2 % in all the incinerators. So,very remote chance of formation of sulphur species in the exhaust.Usually , which type of fouling mechanisom happens ? Any online or offline fouling mitigation measures.Fouling of Upstream of reaction furnace is unlikely.
