Title: British Gas/Lurgi Slagging Gasifier a springboard into synfuels

Abstract

The most developed and widely used fixed bed pressure gasification systems are based on the Lurgi Gasification Process. The British Gas/Lurgi Slagging Gasifier results from the joing together of British Gas Corporation and Lurgi Company technology. The British Gas Slagging Gasification technology offers significant advantages over dry bottom Lurgi and other fixed bed gasification systems. The slagging gasifier has more advantages than disadvantages when compared with entrained flow gasifiers and these advantages are sufficient to give it an economic advnatage in most process situations. The processing of crude Slagging Gasifier gas and the multifarious uses of the resulting clean gas in the chemicals, power generation and fuel gas fields are described. The environmental impact of the process is also discussed and plans for commercialization are considered. 21 refs.

  • Earlier studies by the Electric Power Research Institute were the basis for the study by British Gas/Lurgi of the slagging gasifier as a source of clean fuel gas for a gasification combined-cycle power plant. The current status of the technology of combustion gas turbine design and manufacture exhibits rapid change, providing additional incentive for the study. The goal was to develop a conceptual design to estimate the performance and the costs of capital, operations and maintenance, and electricity for a nominal 500 MW coal gasification combined-cycle power plant using slagging gasifiers. The authors describe the self-contained plant, and summarize performance,more » technology status of components, environmental aspects, and economics. 2 figures, 4 tables.« less
  • British Gas Lurgi slagging gasification and its status of commercial availability are presented. Two important cases for the application of slagging gasification are discussed in some detail: integrated gasification combined cycle (IGCC) power generation, and production of hydrogen from petroleum coke. Cost figures are presented for power generation and hydrogen production. Special attention is given to both present and the more stringent environmental regulations expected in the future.
  • Contract No. EF-77-C-01-2542 between Continental Oil Company and the U.S. Department of Energy requires Continental Oil, as Contractor, to design, construct, and operate a Demonstration Plant capable of converting bituminous coal into pipeline quality gas. Work under this contract started on July 1, 1977. A preliminary design of a Commercial Plant is required under the contract. The process design for the primary gas processing units and most of the by-product units for the Commercial Plant has been completed. This plant is designed to convert 16,879 tons per day of Illinois No. 6 coal into 242 MMSCFD of pipeline gas. Ninemore » operating British Gas/Lurgi slagging gasifiers in a three-train processing system are required for the Commercial Plant. The process design of the Gasification Section and some of the downstream gas processing units has been completed for the Demonstration Plant. This plant is designed to gasify 3240 tons per day of Ohio No. 9 coal in three operating British Gas/Lurgi slagging gasifiers. A 1200 acre site in Noble County, Ohio, has been selected by the Contractor for the location of the Demonstration Plant. Seven runs of a technical support program being carried out by British Gas Corporation at its Westfield Development Centre have been completed. Data from this program combined with the design expertise and historical data available to Lurgi Kohle und Mineraloeltechnik are sufficient to provide a basis for designing the downstream gas processing units for the Demonstration Plant.« less
  • Plant designs, performance data, cost estimates, and bus-bar power costs were developed for a nominal 500-MW integrated coal gasification, combined-cycle power plant. The British Gas/Lurgi slagging, fixed-bed gasifier was employed to produce a clean fuel gas from coal. The clean fuel gas was fired in near-term, advanced technology combustion gas turbines operating at combustor temperatures of 2200/sup 0/F. Gas turbine exhausts were used to produce steam that was employed in a superheat/reheat main steam turbine generator to produce additional power. Duct burners and external combustors were investigated for the purpose of firing any fuel gas available in excess of thatmore » consumed by the gas turbines. The results of the study indicate that the power plant has the potential to provide base-load electricity at a cost that is 10% to 15% lower than the cost of electricity produced by a conventional coal-steam plant. In addition, the plant has the capability for producing very low-cost peak and intermediate load electricity. Harmful emissions from the plant would be considerably reduced in quantity relative to conventional coal-fired plants. 24 figures, 43 tables.« less
  • In May, 1977, U.S. ERDA and Continental Oil Co. signed a contract for approximately $370,000,000 for the design, construction and operation of a Pipeline Gas Demonstration Plant. The 22-month first phase, Development and Engineering, is fully funded by ERDA and budgeted at about $25,000,000. The remaining six-plus years will be funded on a 50/50 industry/government basis. The project involves the design of a Commercial Plant and a Demonstration Plant. All processes except the gasification process have been demonstrated in commercial ventures elsewhere. The gasification process is the British Gas/Lurgi Slagging Gasifier which was developed in a privately sponsored program atmore » Westfield Development Center in 1975. The Commercial Plant design, based on a plant site in Montgomery Co., Illinois, will produce approximately 250 MMSCFD of pipeline quality gas from 1,050,000 LB/HR. (MAF) Illinois No. 6 coal. The Demonstration Plant is a grass-roots facility located in Noble County, Ohio. The plant will process 202,500 LB/HR. of high-sulfur coal (MAF basis) to produce over 50 MMSCFD of pipeline quality gas with a higher heating value exceeding 955 Btu/SCF. A Technical Support Program utilizing a prototype reactor at the Westfield Development Center, Scotland, is designed to yield information confirming the assumptions used in the Demonstration Plant design. Additionally, use of special materials of construction for critical gasifier components will be demonstrated. Early test runs indicate these objectives can be met.« less
