CSIRO’s patented CS-Cap process aims at reducing the costs of amine-based post-combustion capture by combining SO₂ and CO₂ capture using one absorbent in a single absorber column. By avoiding the need for a separate flue gas desulfurization unit, the process offers potential savings for power plants requiring CO₂ capture. High-level cost estimates based on lab and pilot data are presented for two amine reclamation techniques i.e. thermal reclamation and reactive crystallisation. Only regeneration via reactive crystallisation reduces CS-Cap costs below base case FGD/SCR-PCC. Cost estimations suggest a potential reduction of 38–44% in the total plant cost when using the CS-Cap process compared to base case. However, the amine reclaimer operating cost governs the overall cost of the CS-Cap process and is highly sensitive to sulfur content. A 50% reduction is observed when SO₂ levels reduce from 700 to 200 ppm. Comparing levelised cost of electricity and CO₂ avoided costs for CS-Cap against our base case, low sulfur brown coal has a slight (5–7%) cost advantage; however, confirmation requires pilot data on amine recovery.

CSIRO获得专利的CS-Cap工艺旨在通过在单个吸收塔中使用一种吸收剂将SO ₂和CO _2的捕集相结合来降低基于胺的燃烧后捕集的成本。通过避免需要单独的烟道气脱硫装置，该工艺可为需要CO _2的发电厂节省成本捕获。基于实验室和中试数据的高级成本估算针对两种胺回收技术（即热回收和反应结晶）进行了介绍。只有通过反应结晶再生才能将CS-Cap成本降低到基本情况FGD / SCR-PCC以下。成本估算表明，与基本案例相比，使用CS-Cap工艺可将工厂总成本降低38-44％。但是，胺回收器的运行成本决定着CS-Cap工艺的总成本，并且对硫含量高度敏感。当SO ₂含量从700 ppm降至200 ppm时，可观察到50％的降低。比较平准的电力和CO ₂成本与我们的基本情况相比，避免了CS-Cap的成本，低硫褐煤的成本优势较小（5-7％）；但是，确认需要有关胺回收的试验数据。
