Process design and economic evaluation of biomass-based negative emission technologies

Abstract

A palm oil-based polygeneration system (POPS) is simulated to produce the main product of high-purity green diesel as well as the liquefied petroleum gas (LPG) as a by-product. The CO2-negative design includes approaches of (i) a series of cryogenic separators for the recovery of approximately 65.5% of hydrogen feedstock, (ii) the evacuated tube solar collector (ETSC) for reducing 35% flue gas from the furnace, (iii) the amine-based CO2 capture process for pursuing the high-purity CO2 product. The economic analysis of POPS shows that the process becomes economically attractive if the diesel price and crude palm oil should be around 1.98 and 0.47 $kg-1, respectively.
