Book excerpt: This second Topical Report describes the work that was completed between January 1, 1989 and December 31, 1990 in a Cooperative Agreement between Texaco and the US Department of Energy that began on September 30, 1987. During the period that is covered in this report, the development and optimization of in-situ and external desulfurization processes were pursued. The research effort included bench scale testing, PDU scoping tests, process economic studies and advanced instrument testing. Two bench scale studies were performed at the Research Triangle Institute with zinc titanate sorbent to obtain data on its cycle life, sulfur capacity, durability and the effect of chlorides. These studies quantify sulfur capture during simulated air and oxygen-blown gasification for two zinc titanate formulations. Eight PDU runs for a total of 20 days of operation were conducted to evaluate the performance of candidate sorbents for both in-situ and external desulfurization. A total of 47 tests were completed with oxygen and air-blown gasification. Candidate sorbents included iron oxide for in-situ desulfurization and calcium based and mixed metal oxides for external desulfurization. Gasifier performance and sorbent sulfur capture are compared for both air-blown and oxygen-blown operation.

Book excerpt: The objective of this project was to support Texaco's effort to develop the zinc titanate hot-gas desulfurization process for gases produced from their oxygen-blown coal gasifier by answering two key questions that had remained unanswered to date. These questions were: Will chloride in the coal gas affect the performance of the sorbent? Where would the chloride end up following sulfidation and regeneration? Previously, Research Triangle Institute (RTI) completed a bench-scale test series, under a subcontract to Texaco, Inc., for their contract with the US Department of Energy/Morgantown Energy Technology Center (DOE/METC), in which zinc titanate was shown to be a highly promising sorbent for desulfurizing the Texaco O2-blown simulated coal gas. The next step was to evaluate the effect of coal gas contaminants, particularly chloride, on the sorbent. No tests have been carried out in the past that evaluate the effect of chloride on zinc titanate. If ZnO in the sorbent reacts with the chloride, zinc chloride may form which may evaporate causing accelerated zinc loss. Zinc chloride may revert back to the oxide during oxidative regeneration. This may be enhanced in the presence of steam. This report provides results of a three-test series which was designed to give some definitive answers about the fate of chloride in the hot-gas desulfurization process and the effect of chloride on the performance of zinc titanate.

This book was released on 1991 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Research Triangle Institute performed four high-temperature desulfurization tests of zinc titanate sorbents for Texaco, Inc. Two zinc titanate sorbents (L-3196 and L-3014) were tested in fixed-bed mode with simulated oxygen-blown (medium Btu) and air-blown (low Btu) Texaco gas. The zinc titanate sorbents were manufactured as 3/16-in. cylindrical extrudates by United Catalysts, Inc. Tests were performed in a high-temperature, high-pressure, fixed-bed sorbent test unit originally constructed and used on Department of Energy (DOE) contract DE-AC21-86MC23126, DOE Office of Fossil Energy, Morgantown Energy Technology Center (METC). The test unit is described in detail in the December 1988 final report for this contract. Of the four tests conducted, two tests were conducted for the L-3014 sorbent and two tests were conducted for the L-3196 sorbent. The main difference between the two sorbents was their zinc to titanium molar ratio (0.8 for L-3014, 1.5 for L-3196). Properties of these sorbents are described in detail in the Final Report for DOE Contract No. DE-AC2l-86MC23126. Two tests were conducted for each sorbent; one test was conducted with simulated Texaco air-blown gasifier gas and one test was conducted with simulated Texaco oxygen-blown gasifier gas. Each test consisted of five cycles. Each cycle was composed of reductive regeneration, sulfidation, and oxidative regeneration steps. After the fifth sulfidation and after the fifth oxidative regeneration of each test, samples were collected and sent to Texaco. In the following sections, the test procedures are briefly described followed by details of the important results.

This book was released on 1992 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: To help achieve the goal of clean, low cost power generation from coal, Texaco submitted an unsolicited proposal in July 1986 to develop and demonstrate the integration of high temperature desulfurization with the Texaco Coal Gasification Process (TCGP). The main goals of the proposed program were: Develop and demonstrate in-situ desulfurization of synthesis gas in an entrained flow gasifier using both air and oxygen gasification. Develop and demonstrate a high efficiency integrated system on a process development unit (PDU) scale which would include coal preparation, gasification, sulfur removal, particle and trace element removal and a gas turbine. In addition, secondary goals were proposed which would help further major research in which DOE/METC was already involved. These were: Test advanced instruments developed by METC for coal conversion processes. Screen alternative high temperature sulfur removal sorbents that could be used external to the gasifier. Development of these sorbents would provide a backup to the in-situ desulfurization approach. Accomplishments to date are presented.

This book was released on 1995 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The US Department of Energy (DOE) Morgantown Energy Technology Center (METC) is sponsoring research in advanced methods for controlling contaminants in hot coal gasifier gas (coal gas) streams of integrated gasification combined-cycle (IGCC) power systems. The programs focus on hot-gas particulate removal and desulfurization technologies that match or nearly match the temperatures and pressures of the gasifier, cleanup system, and power generator. The work seeks to eliminate the need for expensive heat recovery equipment, reduce efficiency losses due to quenching, and minimize wastewater treatment costs. The goal of this project is to continue further development of the zinc titanate desulfurization and direct sulfur recovery process (DSRP) technologies by (1) scaling up the zinc titanate reactor system; (2) developing an integrated skid-mounted zinc titanate desulfurization-DSRP reactor system; (3) testing the integrated system over an extended period with real coal-gas from an operating gasifier to quantify the degradative effect, if any, of the trace contaminants present in coal gas; (4) developing an engineering database suitable for system scaleup; and (5) designing, fabricating and commissioning a larger DSRP reactor system capable of operating on a six-fold greater volume of gas than the DSRP reactor used in the bench-scale field test. The work performed during the October 1 through December 31, 1995 is described.
