PTQ Q4 2023 Issue

Notes a In the course of the 2023 case study, UOP employed proprietary Honeywell UOP process models for developing the Heat & Mass bal- ances based on first principles of Thermodynamics utilising Unisim Design suite, a kinetic model for modelling the combustion kinetics was used for estimating SOx, NOx, HCN, NH 3 , CO, CO 2 in FCC flue gas, and a semi-empirical/kinetic model was used for yield estimating. Typical Honeywell UOP engineering assumptions and process design guidelines have been utilised. b Determined with help of proprietary Honeywell UOP FCC process models, process design guidelines, and catalysis fundamentals. c The 90 mol% is based on the results of proprietary Honeywell UOP process modelling conducted in 2023. It is expected that the flue gas is cooled to approximately 120ºF to condense the water in the flue gas near atmospheric pressure. d This is based on Honeywell UOP process modelling conducted in 2023 using proprietary models of FCC units. With no consideration for FCC heat balance requirements and possible constraints in the FCC reactor/fractionation/gas concentration section, FCC capacity can be increased by 30% by (i) having CO2 with a molecular weight (MW) of 44 g/mole displace N 2 with an MW of 28 g/mole, and (ii) increasing O2 content from 21 mol% to 28 mol%. e The O2 price is 50 $/t, and equipment pricing is based on USGC. Utility pricing is 0.35 $/kWh electricity, 124 $/t of HP steam, and 19.92 $/t of BFW. The FCC was operating in gasoline mode of operation. Power saving is 873 kWh (because of reduced blower load, recycle compressor in lieu of main air blower). There was an increase in steam generation (22 t/h) and BFW use (23 t/h) because of burning more coke.
