Advanced Exergy, Exergoeconomic, and Exergoenvironmental Analyses of Integrated Solar-Assisted Gasification Cycle for Producing Power and Steam from Heavy Refinery Fuels

Integrated solar-assisted gasification cycles (ISGC) have emerged as a more flexible and environmentally friendly solution for producing power, steam, other high-valued by-products from low-cost opportunity fuels. In this light, paper investigates new ISGC system converting heavy refineries fuels into power steam utilities while enhancing energy efficiency economic environmental performance indicators. approach, solar field two-pressure heat recovery generator were integrated the to improve overall plant viability. The was modelled in MATLAB software, results validated using Thermoflex software. Conventional advanced energy, exergy, exergoeconomic, exergoenvironmental (4E) analyses implemented assess main parameters identify potential improvements. produced 319.92 MW of by feeding on 15.5 kg/s refinery fuel, with thermal 50% exergy 54%. also revealed an investment cost $466 million, evaluated at rate 446 $/min impact 72,796 pts/min. conventional 4E unveiled process feasibilities, particularly oil-rich countries high availability resources.
