Gasification System - Gasifier Optimization and Plant Supporting Systems
Long-Term Refractory Durability Tests
National Carbon Capture Center at the Power Systems Development Facility

Project Number: NT0000749
The National Carbon Capture Center Transport Gasifier consists of an assembly of refractory-lined pipe that includes a mixing zone, a riser, a solids separation and collection unit, and a solids recycle section. By combining the use of strategically placed, precision instrumentation and monitoring controlled solids inventory and solids circulation with the ability to operate across a wide range of flow rates and adjustable process conditions, the facility is monitoring and measuring slag/refractory interactions and testing various materials for durability. New materials research and development results, provided to manufacturers, aims to improve gasifier availability and reduce costs associated with plant shut-downs for repairs. In the most severe slagging gasifiers, refractories can require replacement every three months, where the gasifier system is shut down for one to two weeks, costing millions of dollars.
