Method & Evidence

AimTo assess the technical and economic feasibility of a 1 million tons/year CO2 capture project in a petrochemical setting, incorporating novel energy-saving measures.

MethodCase study analysis and techno-economic assessment.

ProcedureA 1 million tons/year CO2 capture project was designed and implemented using a compression-condensation-purification process. Molecular sieves were used for drying and structured packing for purification. Two energy-saving processes were integrated: a lithium bromide refrigerator unit for waste heat recovery and an expansion generator unit for pressure energy recovery. The project's layout, land use, utility consumption, and economic viability (investment, payback period, sales price) were analyzed.

ContextPetrochemical industry, specifically a coal gas stream from a fertilizer plant.
