Carbon Capture - Post-Combustion Capture

Bench-Scale Silicone Process for Low-Cost CO2 Capture

Performer: General Electric Company

Project No: FE0007502

Project Description

GE Global Research, along with their partners GE Energy and SiVance LLC, will continue the development and testing of a novel aminosilicone-based solvent using a continuous bench-scale system to capture CO2 from simulated coal-fired flue gas. In a previous DOE-funded project (DE-NT0005310), the novel solvent was developed and tested in a laboratory-scale continuous CO2 capture system. The testing and associated detailed cost modeling and analysis demonstrated that the novel solvent has superior performance for CO2 capture as compared to a baseline monoethanolamine (MEA) process.

As this solvent system effectively demonstrated cost-effective CO2 capture from flue gas at the laboratory scale, development and testing of a bench-scale system represents a readily achievable next step on the path to commercialization.

Previously measured experimental data from the laboratory-scale CO2 capture system will be used to design the continuous bench-scale system. Basic engineering data, such as kinetics and mass transfer information, will be obtained at the bench scale to determine process scalability and likely process economics. A manufacturing plan for the aminosilicone solvent and price model will be used for optimization of the solvent system. GE Global Research will design, build, and operate the bench-scale system and gather the engineering and property data required to assess the technical and economic feasibility of the process. GE Energy will be responsible for developing a model of the bench-scale process and the cost of electricity (COE), performing the technical and economic feasibility studies, and developing the scale-up strategy. SiVance will evaluate the manufacturability of the aminosilicone capture solvent, analyze the cost to manufacture the solvent, provide material for bench-scale and property testing, and perform a technology Environmental, Health, & Safety (EH&S) risk assessment.
