(208d) The Syngas Chemical Looping Processes for Hydrogen and Electricity Co-Generation with Carbon Capture: Pilot Plant Development and Operation
AIChE Annual Meeting
Monday, November 14, 2016 - 4:30pm to 4:55pm
The present paper summarizes key developments of the 250 kWth â?? 3MWth SCL pilot plant constructed at the National Carbon Capture Center (NCCC). An overview of the process design, cold flow model studies, and construction will be provided. Operational challenges overcome in the SCL pilot plant included the development of auxiliary equipment such as a pilot-scale raw gas burner and baghouse. An advanced high temperature, high pressure solid flow measurement device, electrical capacitance volume tomography (ECVT), was also tested for instantaneous solid flow control in this chemical looping system. The SCL pilot plant has been successfully demonstrated to achieve nearly full syngas conversion. Start-up and operational results including solid circulation studies, process heat up, syngas conversion, and solids analysis will be presented and discussed.
