Title: Scaleup of IGT MILDGAS Process to a process development unit

Abstract

The MILDGAS process is capable of processing both eastern caking and western non-caking coals to yield a slate of liquid and solid products. The liquids can be processed to produce: feedstocks for chemicals; pitch for use as a binder for electrodes in the aluminum industry; and fuels. Depending on the feed coal characteristics and the operating conditions, the char can be used as an improved fuel for power generation or can be used to make form coke for steel-making blast furnaces or for foundry cupola operations. The specific objectives of the program are to: design, construct, and operate a 24-tons/day adiabatic process development unit (PDU) to obtain process performance data suitable for design scaleup; obtain large batches of coal-derived co-products for industrial evaluation; prepare a detailed design of a demonstration unit; and develop technical and economic plans for commercialization of the MILDGAS process. In this paper, the authors present the process design of the PDU facility, a description of the expected product distribution and the project test plan to be implemented in the program.

  • The USDOE is sponsoring development of technology for the mild gasification of coal. The Institute of Gas Technology (IGT) mild gasification process incorporates a combined fluidized bed-entrained bed reactor designed to handle all types of coals. The type of coal used and the market available for the char, which constitutes up to 70% of the co-products, are interrelated. The char could be used to produce form coke, utility fuel, gasification feedstock, or low-cost activated adsorbent char. The process could be integrated with a conventional coal preparation plant, using a stream of high-moisture coal fines. Mild gasification of a coking ormore » marginally coking coal could produce a form-coke for the steel industry and foundries and help relieve the shorter in US coke supplies. The development of a mild gasification process at IGT has been supported by the USDOE since September 1987, with the operation of a 100-lb/h capacity isothermal process research unit (PRU) to investigate the effects of operating conditions and to determine the two coals, one from Illinois and one from West Virginia. The PRU results have been used to design a 24-ton/day adiabatic process development unit (PDU). 3 refs., 4 figs., 1 tab.« less

  • US peat resources are the third largest in the world and are estimated to be about 1440 quads, equivalent to 240 billion barrels of crude oil. In the contiguous 48 states, peat deposits are generally located in areas with no other significant fossil fuel resources. Therefore, for those areas, peat represents an important source of energy. Peat conversion research at the Institute of Gas Technology (IGT) started in 1974 under sponsorship of the Minnesota Gas Company (Minnegasco). Since 1976, IGT has been working on a peat gasification program jointly funded by the US Department of Energy and Minnegasco. Systematic testsmore » have been conducted in laboratory- and process development unit (PDU)-scale equipment to evaluate the conversion of peat to synthetic fuels. Tests have been conducted with peats from Minnesota, North Carolina, and Maine. The results show that, on the basis of chemistry, peat is a better raw material than coal from which to make substitute natural gas (SNG) as well as gasoline blending feedstock because a greater fraction of the feed carbon is converted to these products under milder operating conditions. Also compared with coal, peat conversion permits more flexibility in the relative yields of gas and liquid hydrocarbons. Peats from different regions could have different conversion and yield characteristics as demonstrated by tests on peats from Minnesota, North Carolina, and Maine. The estimates show that the economics of converting Minnesota peat (containing 50% moisture) to SNG by the IGT PEATGAS Process is competitive with those of converting Eastern US coal to SNG.« less
  • The authors review the development of the RENUGAS process, which uses a fluidized-bed instead of a moving-bed gasifier. They describe the process research unit and the gasification test results on feed properties and effects of temperatures. Tests to date show that pressurized gasification at 300 psig, 1390 deg. to 1800 deg. F, and feed rate up to 1050 1b/hr of woody biomass is simple to operate. Total carbon conversion exceeds 92% above 1500 deg. F, and recycling the entrained char could raise that level. Other results identify the oxygen requirement, level of methane production, and the dry gas yield andmore » gross calorific value of the fuel gas, which ranges from 290 to 360 Btu. The process data will be used to conduct environmental assessments and techno-economic analyses. 5 references, 6 figures, 2 tables.« less
