MSP engineering demonstration at TCM is a critical step in the road map to scale-up
Project Objectives(DOE Contract: FE0031588)
• Perform integrated MSP testing at engineering scale for long-term periods under dynamic and continuous steady-state conditions with a real flue gas stream to address concerns relating to scale-up and integration of the technology to coal-based power plants;
• Operate the MSP with advanced heat integration to improve the process efficiencies;
• Study the solvent and water management strategies; and• Collect critically important data for a detailed techno-economic
analysis (TEA) and for further process advancements to reach the DOE’s goal of $30/tonne of CO2 by 2030.

Mixed-Salt Process (MSP)
Process Highlights:- Reduced ammonia emissions- Enhanced efficiency- Reduced reboiler duty - Reduced CO2 compression energy
A SIGNIFICANT PARASITIC POWER REDUCTION COMPARED TO MEA !
How it works:Selected composition of potassium carbonate and ammonium salts
• Overall heat of reaction 35 to 60 kJ/mol (tunable)• Excellent solvent physical properties
Absorber operation at 20o - 40o C at 1 atm with 30-40 wt.% mixture of saltsRegenerator operation at 120o - 160o C at 10-15 atm
• Produce high-pressure CO2 stream
High CO2 cycling capacity

NH3 (ppmv)011650188395651302515200Figure 8 shows that in MSP modeling most of the CO2 capture had occurred in absorber 2 as intended.
In CAP, due to the low absober operational temperature -to keep the ammonia vapor pressure low- the Co2 captue in each of the absorbers are only moderate at best.
T at the Bottom16.2920.5524.41916This is very good news as the absorber size can be very small for MSP demonstations
In case 600-10, the CO2 absorption in Absorber 3 is very low due to the high dissolved CO2 caoncentration ot reduced th eammonia vapor pressure.
12 bar
Figure 7 shows that even at 5 to 10 C degree operation, CAP has very high ammonia emissions from all three absorbers. The ammmonia emission afer the water wash fro Cap and MSP are 400 and 10 ppm, repectively.
