Feb 13, 2011 Entering Kinetic Data In Hysys - posted in Chemical Process Simulation: Dear AllI am currently doing a simulation of Water Gas Shift (WGS) reactor in HYSYS and have met with some problems with entering the kinetic data into HYSYS. I have used a PFR to simulate the packed bed reactor together with a kinetic type reaction.In HYSYS, under the Parameters tab of keying in the reaction … read more
HYSYS. 2.3.3 Defining reactions and formation of reaction sets: In this simulation, the procedure of ammonia production involves sets of reactions; primary reforming, secondary reforming, high and low shift conversion, methanation, ammonia converter. Figures from (02) to (07) give input information to the making of different reactions sets. read more

reactions by feeding the fuel, water and air together into the reactor. The thermal energy generated from oxidation is absorbed by SR and hence the overall temperature is lower. This is favourable for the water-gas shift reaction which consumes carbon monoxide and produces more hydrogen. read more
water-gas-shift conversion. Additional steam is added, and the temperature is reduced to 315 to 370 . o. C to obtain more favorable equilibrium conditions. A single stage converts 80 to 95% of the residual CO to CO. 2. and H. 2. Because the reaction is exothermic, the reactor temperature rises; this enhances the read more
Dec 01, 2014 In ASPEN HYSYS, all gasification reactions have been modeled as an equilibrium reaction except oxidation reactions of carbon; which have been modeled as conversion reactions. Water gas reaction (G-3) is the fundamental reaction giving rise to hydrogen in synthesis gas and higher temperature favors the formation of hydrogen owing to its ... read more
Simulation of water gas shift reactorThe equilibrium CO concentration at a temperature of 750 o C and W/F ratio of 2.0 is about 12 mol% according to Lattner and Harold [15]. The CO content can be reduced to about 0.5% by reacting it with water at lower temperatures to produce additional hydrogen according to the WGS reaction (Eq. 6). read more
In the SRR, (1) is the ma in reaction and generate s most of the hydrogen. The reaction (2) due to its en dothermic nature occurs in a lower extension in the SRR. The syngas stream composition is CO and H 2, in this process CO2 and H 2O are also present in gas state. The main purpose of the water gas shift reactor (WGSR) is to carry out the reaction read more
The second reaction is the Water Gas Shift Reaction in which yet more hydrogen is produced and the CO changed to CO 2 (this is especially important in ammonia sysnthesis as both CO and CO 2 will poison the catalyst used to make ammonia from hydrogen and nitrogen, and the CO is harder to remove than CO 2). Note that the Water Gas Shift is an equilibrium reaction and is modeled as a reversible … read more
