Abstract

For example, methods and compositions for physical solvent carbon capture. Solvents may contain 2‑amino‑2‑methylpropanol, 2‑piperazine‑1‑ethylamine, diethylenetriamine, 2‑methylamino‑2‑methyl‑1‑propanol and potassium carbonate or carbonic acid Aqueous mixture of potassium buffer salts. The solvent may also contain less than 75% by weight of the dissolution medium (ie, water), and may have a single liquid phase. The solvent and process have favorable regeneration energy, chemical stability, vapor pressure, total heat consumption, net cycle capacity and reaction kinetics.

Description

[0001] Cross reference to relevant application data [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 040,911, which is hereby incorporated by reference. technical field [0003] This application relates generally, and more particularly, to carbon capture. Background technique [0004] Separation of CO from gas streams in food production, natural gas sweetening and other processes 2 It has been commercialized for decades. Solvent capture based on aqueous monoethanolamine (MEA) is currently considered to be the 2 The best commercially available technology and is the benchmark against which future developments in the field are estimated. Unfortunately, no amine-based systems have been designed to treat the large volumes of flue gas produced by pulverized coal power plants. Estimates scaled to adjust amine-based CO 2 The required size of the capture system to such a plant would cause an 83% increase in the total cost of electricit...
