Development of an advanced continuous mild gasification process for the production of coproducts. Task 4, Mild gasification tests

Description: Western Research Institute (WRI) teamed with the AMAX Research and Development Center and Riley Stoker Corporation on Development of an Advanced, Continuous Mild-Gasification Process for the Production of Coproducts under contract DE-AC21-87MC24268 with the Morgantown Energy Technology of the US Department of Energy. The strategy for this project is to produce electrode binder pitch and diesel fuel blending stock by mild gasification of Wyodak coal. The char is upgraded to produce anode-grade carbon, carbon black, and activated carbon. This report describes results of mild-gasification tests conducted by WRI. Char upgrading tests conducted by AMAX will be described in a separate report.

Addition of devolatilization equations to synthane computerized mathematical model. Quarterly report, September 15--December 15, 1978

Description: Six approaches to devolatilization modeling have been reviewed. Two have been selected for further evaluation: the Vand-type model of Anthony and Howard and the diffusion model of Russel et al. The first of these treats particles under kinetic control only. The second includes some mass transfer control along with kinetic control. Behavior of particles in the SYNTHANE process appears to be in the transition region between kinetic and mass transfer control. Work during the next quarter will focus on the temperature history of average particles in the carbonizer of the SYNTHANE process and on the methods by which the two devolatilization models chosen will be used to describe conversion in the SYNTHANE carbonizer.

PNNL Coal Gasification Research

Description: This report explains the goals of PNNL in relation to coal gasification research. The long-term intent of this effort is to produce a syngas product for use by internal Pacific Northwest National Laboratory (PNNL) researchers in materials, catalysts, and instrumentation development. Future work on the project will focus on improving the reliability and performance of the gasifier, with a goal of continuous operation for 4 hours using coal feedstock. In addition, system modifications to increase operational flexibility and reliability or accommodate other fuel sources that can be used for syngas production could be useful.

Startech Hydrogen Production Final Technical Report

Description: The assigned work scope includes the modification and utilization of the Plasma Converter System, Integration of a StarCell{trademark} Multistage Ceramic Membrane System (StarCell), and testing of the integrated systems towards DOE targets for gasification and membrane separation. Testing and evaluation was performed at the Startech Engineering and Demonstration Test Center in Bristol, CT. The Objectives of the program are as follows: (1) Characterize the performance of the integrated Plasma Converter and StarCell{trademark} Systems for hydrogen production and purification from abundant and inexpensive feedstocks; (2) Compare integrated hydrogen production performance to conventional technologies and DOE benchmarks; (3) Run pressure and temperature testing to baseline StarCell's performance; and (4) Determine the effect of process contaminants on the StarCell{trademark} system.

ENCOAL Mild Coal Gasification project. Technical progress report No. 7, April 1, 1992--June 30, 1992

Description: Commissioning of the plant dominated the activities of the ENCOAL field group during this reporting period. The operator training classes were completed, initial plant start-up commenced. On June 17, 1992 all systems were fully integrated and the ENCOAL Mild Gasification Plant became fully operational. The plant operated continuously for 24 hours, and both PDF and CDL were produced. Construction of the project was 100% complete by the end of May. As a result of the construction progress, demobilization of KCI and their subcontractors was concluded. An electrical and instrumentation contract was also awarded during the quarter. This contract, combined with the mechanical maintenance contract awarded earlier, provided excellent assistance for plant commissioning and final construction activities.

Development of an advanced, continuous mild gasification process for the production of co-products. Task 4.8, Decontamination and disassembly of the mild gasification process research unit and disposal of co-products

Description: Prior to disassembly of the CFBR, accumulated tar residue must be removed from the reactor, piping and tubing lines, and the condenser vessels. Based on experience from the CFBR mild gasification tests, lacquer thinner must be pumped through the unit for at least one hour to remove the residual tar. The lacquer thinner wash may be followed by a water wash. The CFBR will be disassembled after the system has been thoroughly flushed out. The following equipment must be disassembled and removed for storage: Superheater; Water supply pump; Coal feed system (hopper, auger, ball feeder, valves); Reactor; Cyclone and fines catch pot; Condensers (water lines, glycol bath, condenser pots, valves); and Gas meter. After the process piping and reactor have been disassembled, the equipment will be inspected for tar residues and flushed again with acetone or lacquer thinner, if necessary. All solvent used for cleaning the system will be collected for recycle or proper disposal. Handling and disposal of the solvent will be properly documented. The equipment will be removed and stored for future use. Equipment contaminated externally with tar (Level 4) will be washed piece by piece with lacquer thinner after disassembly of the PRU. Proper health and safety practices must be followed by the personnel involved in the cleanup operation. Care must be taken to avoid ingestion, inhalation, or prolonged skin contact of the coal tars and lacquer thinner. Equipment contaminated internally by accumulation of residual tar or oil (Level 5) will be flushed section by section with lacquer thinner. The equipment will be washed with solvent both before and after disassembly to ensure that all tar has been removed from the piping, pumps, gas quench condensers, light tar condensers, and drain lines. The coal tars wig be separated from the solvent and incinerated.

The Vermont Gasifier

Description: A new demonstration biomass gasifier in Burlington, Vermont, is a major advance toward biopower systems of the 21st century. The purpose of the project is to verify design and operating characteristics of this gasification technology at an intermediate size. The Vermont gasifier is rated at 200 tons of biomass per day. The demonstration will allow further scale-up to a first-of-its-kind commercial gasifier to be demonstrated in the future at an industrial or utility scale.

Description: This report presents a Conceptual Design and Evaluation of Commercial Plant report in four volumes as follows: I - Executive Summary, II - Commercial Plant Design, III - Economic Analyses, IV - Demonstration Plant Recommendations. Volume II presents the commercial plant design and various design bases and design analyses. The discussion of design bases includes definition of plant external and internal considerations. The basis is described for process configuration selection of both process units and support facilities. Overall plant characteristics presented include a summary of utilities/chemicals/catalysts, a plant block flow diagram, and a key plot plan. Each process unit and support facility is described. Several different types of process analyses are presented. A synopsis of environmental impact is presented. Engineering requirements, including design considerations and materials of construction, are summarized. Important features such as safety, startup, control, and maintenance are highlighted. The last section of the report includes plant implementation considerations that would have to be considered by potential owners including siting, coal and water supply, product and by-product characteristics and uses, overall schedule, procurement, construction, and spare parts and maintenance philosophy.
