The aim of this paper is to analyze various CO2 compression processes for postcombustion CO2 capture applications for 900 MW pulverized coal-fired power plant. Different thermodynamically feasible CO2 compression systems will be identified and their energy consumption quantified. A detailed thermodynamic analysis examines methods used to minimize the power penalty to the producer through integrated, low-power compression concepts. The goal of the present research is to reduce this penalty through an analysis of different compression concepts, and a possibility of capturing the heat of compression and converting it to useful energy for use elsewhere in the plant.

Streszczenie

Celem niniejszej pracy jest analiza róznych procesów sprezania CO2 wychwyconego ze spalin bloku energetycznego o mocy 900 MW na pył weglowy. Przedstawiono szereg róznych procesów sprezania i okreslono zuzycie energii kazdego z nich. Szczegółowa analiza termodynamiczna umozliwiła okreslenie sposobów zminimalizowania kosztów energii poprzez dobór najsprawniejszego procesu sprezania oraz wykorzystanie ciepła sprezania w obiegu cieplnym siłowni.
