Molten salt coal gasification process development unit, Phase 2. Quarterly technical progress report No. 1, July-September 1980

Abstract

This represents the first quarterly progress report on Phase 2 of the Molten Salt Coal Gasification Process Development Unit (PDU) Program. Phase 1 of this program started in March 1976 and included the design, construction, and initial operation of a PDU to test the Molten Salt Coal Gasification Process. On July 24, 1980, Phase 2 of the program was initiated. It covers a 1-year operations program utilizing the existing PDU and is planned to include five runs with a targeted total operating time of 9 weeks. The primary activities during the period covered by this report related to preparations for PDU Run 6, the initial run of the Phase 2 program. These activities included restaffing the PDU operations group, reactivation of the facility, and effecting plant modifications and improvements based on an evaluation of previous operation experience. The Melt Withdrawal System which had proven unreliable during the previous runs, was completely redesigned; thermal and flow analyses were performed; new components procured; and assembly initiated. Run 6 which is scheduled for the next report period, is aimed primarily at verifying the adequacy of the redesigned Melt Withdrawal System.
