Neumann Systems Group, Inc. (NSG) has designed, constructed, and tested a 0.5-MW scale patented NeuStream® absorber at the Colorado Springs Utilities (CSU) Martin Drake #7 power plant. The absorber employs nozzle technology proven during a previously completed 20-MW NeuStream-S flue gas desulfurization (FGD) pilot project, as well as a 6-m piperazine (PZ) solvent, which is an efficient solvent for capturing carbon dioxide (CO2). The goal of the project is to show that the absorber system is capable of significantly reducing the process equipment footprint and the CO2 capture system cost.
