A simulation study of the effect of post-combustion amine-based carbon-capturing integrated with solar thermal collectors …

2021/3/3 · Post-combustion carbon capture with solvent designed to sequestrate carbon from power plant is a promising and well-known technology. However, a vital drawback is the reduction of the power plant output due to the energy required to separate captured CO2 from the solvent, known as a re-boiler duty. In this paper, two configurations were simulated and economically …

Boiler - ID:5c16a869e7b04

From this data the factor of evaporation is 1.1514 and the evaporation per hour from and at 212 degrees is 65,671 pounds. Hence the evaporation from and at 212 degrees per pound of dry coal is 65,671 ÷ 5609 = 11.71 pounds. The efficiency of boiler, furnace and grate is: ( 11.71 × 970.4 ) ÷ 14,225 = 79.88 per cent.

CHAPTER 6:The Energy Balance for Chemical Reactors

2012/1/1 · This paper presents a description of the CO2 removal process of 500MW coal and gas fired power plants. The parameters and other operating conditions for Aspen Plus rate based model were selected to achieve 85% of CO2 removal. The effects of absorber pressure and packing height on re-boiler duty are studied. Re-boiler duty is decreasing with the
