The completion of the low Btu gas, low temperature cleanup system pilot plant represents a major step toward a complete integrated coal gasification pilot plant which simulates the full-scale commercial Coal Gasification Combined Cycle Plant. Several important programmatic and technical milestones in the HTTT Program were attained during the design, construction, and startup of the pilot-scale chemical cleanup system: Process and detail system design, procurement, and construction were completed within two weeks of the original mechanical completion date estimated over 1-1/2 years previously. The full cleanup facility was brought on-line for fired tests within one week of the date targeted. The ability to operate the system in a 30-hr fired test after only three short attempts at fired operation, attests to the excellence of the plant design, preparation, and operation personnel. The full cleanup system operated with only two GE supervisors and two temporary hired laborers per shift during this initial phase of operation. The performance of the Benfield system met or exceeded expectations based on sulfur and carbon dioxide removal. The reheat and saturation equipment performed well and controllably. No evidence of foaming or mist carry-over to the process gas stream was observed, and the particulate and alkali loading of the clean process gas was well within design limitations. The ability of the separators to decant heavy tars has not yet been demonstrated. From this initial period of testing, it appears that the system met or exceeded the design goals in all critical areas. Obviously, additional and more extended testing will be required to fully evaluate the long-term operation and performance of the system. Modifications to the facility made to minimize or eliminate the operational problems observed during the startup and evaluation tests are described.
