Book excerpt: The objective of this work is to investigate, in the laboratory, the parameters associated with a chemically assisted in situ recovery procedure, using hydrogen chloride (HCI), carbon dioxide (CO2), and steam (H2O), to obtain data useful to develop a process more economic than existing processes and to report all findings. The technical progress of the project is reported. The project status is that the solutions to the problems discussed in the third quarter status, were found to function satisfactorily. Future needs have been considered, and appropriate equipment and instrumentation changes have been designed. Only one experiment was performed this quarter, with some improvement over the previous experiments. The increase in shale oil recovery followed directly from the changes discussed last quarter, but the improvement could have been larger with wider-spread implementation of the changes. Equipment was purchased to rectify the need, and will be installed shortly. Further, a minor change in the design was necessary to account for the brittleness of high temperature electrical resistance heating tapes. The focus of the work this quarter has been on the development of computer software to enable the use of on-line parameter identification, the design of the instrumentation necessary to adequately observe the system, and the design of a continuous gas mixer to implement the experiment.

Available in PDF, EPUB and Kindle. Book excerpt: The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated on a small scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a continuous process kiln. Similar chemical and physical conditions (heating, mixing, pyrolysis, oxidation) exist in both systems. The two most important data objectives in this phase of the project are to demonstrate (1) that the heat recovery projected for this project is reasonable and (2) that an oil shale kiln will run well and not plug up due to sticking and agglomeration. The following was completed this quarter. (1) Twelve pyrolysis runs were made on five different oil shales. All of the runs exhibited a complete absence of any plugging, tendency. Heat transfer for Green River oil shale in the rotary kiln was 84.6 Btu/hr/ft2/°F, and this will provide for ample heat exchange in the Adams kiln. (2) One retorted residue sample was oxidized at 1000°F. Preliminary indications are that the ash of this run appears to have been completely oxidized. (3) Further minor equipment repairs and improvements were required during the course of the several runs.

Available in PDF, EPUB and Kindle. Book excerpt: The Adams Counter-current shale oil recovery process is an improved retorting technology enabling highly efficient oil recovery from oil shale. The high efficiency results primarily from the following facts: it (1) recovers the ash heat to preheat the feed ore; (2) burns and uses the coke energy and (3) operates without using hot ash recycling as a heat carrier. This latter feature is doubly important, contributing to high oil yield and to the generation of highly reactive coke which can be burned below 1000°F, avoiding the endothermal calcination of the mineral carbonates and helping to clean the ash of contaminants. This project demonstrates that oil shale can be retorted under the specified conditions and achieve the objectives of very high efficiency. The project accomplished the following: 51 quartz sand rotary kiln runs provided significant engineering data. A heat transfer value of 107 Btu/hr/ft2/°F was obtained at optimum RPM; eight oil shale samples were obtained and preliminary shakedown runs were made. Five of the samples were selected for kiln processing and twelve pyrolysis runs were made on the five different oil shales;average off recovery was 109% of Fisher Assay; retorted residue from all five samples was oxidized at approximately 1000°F. The ash from these runs was oxidized to varying extents, depending on the oil shale and oxidizing temperatures. While 1000°F is adequately hot to provide process heat from coke combustion for these ores, some Eastern oil shales, without mineral carbonates, may be oxidized at higher temperatures, perhaps 100--300 degrees hotter, to obtain a more complete oxidation and utilization of the coke.

Available in PDF, EPUB and Kindle. Book excerpt: The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated at bench-scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a larger continuous process kiln. For example, similar conditions of heatup rate, oxidation of the residue and cool-down prevail for the element in both systems. This batch kiln is a unit constructed in a 1987 Phase I SBIR tar sand retorting project. The kiln worked fairly well in that project; however, the need for certain modifications was observed. These modifications are now underway to simplify the operation and make the data and analysis more exact. The second quarter agenda consisted of (a) kiln modifications; (b) sample preparation; and (c) Heat Transfer calibration runs (part of proposal task number 3 -- to be completed by the end of month 7).

Available in PDF, EPUB and Kindle. Book excerpt: A major push was made to identify the hydrocarbon and heteroatom types present in raw shale oil. A comprehensive, qualitative picture of the 400°C material has been obtained. In addition to the expected types, e.g., pyridines, pyrroles, indoles and phenols, the presence of aliphatic carboxylic acids, ketones and nitrites was confirmed. Most importantly, heteroatom types are able to be concentrated nearly quantitatively by liquid-liquid extraction with polar solvents. Compound types characterization of the400°C material, as well as rapid, routine analysis of separations fractions, requires new methodologies founded in the Z-BASIC concept. Advances were made in establishing the interface protocol needed to utilize Z-BASIC methodologies for interpretation of gc-ms output data. It is anticipated that all interface protocols will be completed and a computerized reporting system will be in place by the end of the next quarter. Progress reports were made at the Contractor's Review Meeting (METC), November 16th and at the Eastern Oil Shale Symposium (Lexington), November 17th. Research results continue to be well-received. The concept of a thermodynamically logical map of potential products from shale oil is a sound approach to value-enhancement research. From a commercial perspective, the concept of establishing a demand for raw shale oil at a reasonable purchase price of, say $30/bbl, is increasingly being recognized as the best means of pulling shale oil into the marketplace.

Available in PDF, EPUB and Kindle. Book excerpt: A review of the marketing, compositional analysis, and process data has pointed to a simplification of the process scheme envisaged for the phase-H continuous process work. This translates into a higher probability of success, both for the R & D and the likelihood of securing an industrial partner for future commercialization. The phase-II PDU construction work is well-along and will be completed in the next quarter. The high efficiency distillation unit is complete and the liquid-liquid extraction unit is operable at ambient temperature and pressure conditions. Flow diagrams of preferred processes for recovery of refinery feeds, aromatics, waxes, and lube oils from oil shale are presented.

Available in PDF, EPUB and Kindle. Book excerpt: All tasks are on schedule, or ahead of schedule. Particular progress has been made in identifying industrial entities, commodities and specialty products of target interest for shale oil-derived products. There is clearly a major emphasis worldwide on new chemicals and shale oil-derived structures are similar to many of these chemicals of interest. Details of the mathematical modeling, programming and algorithm development have progressed with excellent results. Considerable effort will be required to interface these with the output of the gc/ms but we are receiving excellent support from Hewlett Packard in this regard. The ability to concentrate particularly valuable compounds with reasonable projected cost processes continues to show promise. In one system, a single-stage extraction recovered 87% of the total nitrogen in an extract representing only 33% of the fraction. Special attention is being paid to both nitrogen types and oxygen types. The raffinates from the polar solvent extractions will be evaluated for their oil and wax contents. All of the start-up infrastructure is now in place. Subcontracts have been initiated and equipment and supplies have been procured. We are now planning a major push to reach some general findings by early in 1994. From these findings, we will be prepared to focus on experimental verification of process design needed for the second program phase.
