Analysis of Data from a Downhole Oil/Water Separator Field Trial in East Texas

Description: Downhole oil/water separator (DOWS) technology is available to separate oil from produced water at the bottom of an oil well. Produced water can be injected directly to a disposal formation rather than lifting it to the surface, treating it there, and reinjecting it. Because of a lack of detailed performance data on DOWS systems, the U.S. Department of Energy (DOE) provided funding to secure DOWS performance data. A large U.S. oil and gas operator offered to share its data with Argonne National Laboratory. This report summarizes data from the DOWS installation in eastern Texas.

Fundamental studies for sol-gel derived gas-separation membranes

Description: We prepared silica membranes using sol-gel techniques and explored the effects of postdeposition sintering, capillary stresses developed during drying, and surface derivatization of the membranes with titanium iso-propoxide. We observed that both partial sintering of membranes and development of larger-capillary stresses during membrane formation lead to consolidation of the membrane structure as evidenced by increased ideal separation factors, e.g. {alpha}CO{sub 2}2/CH{sub 4} > 250 over the temperature range of 160 to 220 C. Surface derivatization was also shown to be an effective tool to reduce the membrane pore size in an angstrom by angstrom fashion, resulting in comparable separation factors. What`s more, the altered pore surface chemistry of TiO{sub 2} derivatized membranes may lead to improved stability and impart catalytic properties to the membrane surface.

Summary of Data from DOE-Subsidized Field Trial No.1 of Downhole Oil/Water Separator Technology, Texas Well Bilbrey 30-Federal No. 5 Lea County, New Mexico

Description: This reports, DOWS technology reduced the quality of produced water that is handled at the surface by separating it from the oil downhole and simultaneously injecting it underground. The two primary components of a DOWS system are an oil/water separation system and at least one pump to lift oil to the surface and inject the water. Two basic types of DOWS have been developed -- one type using hydrocyclones to mechanically separate oil and water and one relying on gravity separation that takes place in the well bore.

POC-scale testing of oil agglomeration techniques and equipment for fine coal processing

Description: This report covers the technical progress achieved from January 1, 1998 to April 31, 1998 on the POC-Scale Testing of Oil Agglomeration Techniques and Equipment for Fine Coal Processing. Experimental work was carried out with two coal fines. One sample originated from pond (Drummond Pond Fines) while the second was pulverized Luscar Mine coal. Both samples were tested at the laboratory batch-scale while only Luscar Mine Coal was processed on the 250 kg/h continuous system. Significant progress was made on optimization of process conditions for Pond Fines. The test results showed that ash could be reduced by about 42% at combustible recovery exiting 94%. It was also found that pond fines required significantly longer conditioning time than freshly pulverized run of mine coal. Continuous bench-scale testing carried out with Luscar Mine coal included rod mill calibration, plant equipment and instrumentation check-up, and parametric studies. Compared with batch-scale tests, the continuous bench-scale process required more bridging oil to achieve similar process performance. During the current reporting period work has been commenced on the final engineering and preparation of design package of 3t/h POC-scale unit.

POC-scale testing of oil agglomeration techniques and equipment for fine coal processing

Description: This report covers the technical progress achieved from April 1, 1998 to June 30, 1998 on the POC-Scale Testing of Oil Agglomeration Techniques and Equipment for Fine Coal Processing. Continuous bench-scale runs were carried out with Luscar Mine coal. The main objectives were to optimize process conditions for a proposed jet processor and to compare its performance with a standard high-shear mixer. A total of three runs consisted of 15 testing periods was carried out. Both conditioning devices performed very well with combustible matter recovery exceeding 96%. Slightly higher coal recovery was observed for high-shear mixer, while lower ash contents were achieved when jet processor was used for coal conditioning. During the current reporting period work has been continued and completed on the engineering and design package of a 3 t/h POC-scale agglomeration unit. Preliminary design package prepared by Thermo Design Engineering, a subcontractor to this project, was submitted to DOE for revision and approval.

The anticyclone: A device for nonimpact particle separation

Description: It is often desirable to separate particles from a particle-laden fluid stream. This is typically accomplished by passing the stream through a filter, an impactor, or a cyclone. In each of these devices, particles encounter obstacles in the flow path (i.e. filter material, the impaction surface, the cyclone side wall). However, in some applications, it is desirable to prevent particles from impinging on solid surfaces. For example, particle interaction with a solid surface may contaminate the surface, modify the particles via mechanical or chemical processes, or adversely affect the surface via material modification or heat transfer. In such situations, it is still possible to separate particles from the particle-laden flow stream by transferring them to another adjacent flow stream. This transfer of particles from one flow stream to another is termed nonimpact particle separation. One type of device that separates particles from a flow stream by nonimpact particle separation is the anticyclone. In contradistinction to a cyclone, the particle-laden flow is deflected from its original direction by a wall that curves away from the original flow direction, rather than into it. The computational fluid dynamics code FIDAP (Fluid Dynamics International) is used to perform two-dimensional fluid-flow and particle-motion calculations for a representative device geometry. These calculations indicate that the anticyclone geometry examined accomplishes nonimpact particle separation, as expected. Flow patterns and overall particle-separation characteristics are found to be fairly insensitive to Reynolds number for values above 100 regardless of whether the flow is laminar or turbulent. An approximate analytical relation describing anticyclone nonimpact particle separation is developed and validated by comparison to the numerical simulations. The additional information required to design useful devices employing nonimpact particle separation is outlined.

Use of silica sols in inorganic molecular sieving membranes

Description: Polymeric silica sols, were deposited on commercial {gamma}-alumina supports to prepare gas separation membranes. Optimization of the sol fractal dimension and radius of gyration and minimization of condensation rate led to formation of a discrete film with pores of molecular dimensions. Two coatings of this sol (A2{sup **}) led to a membrane with ideal separation factor of 7 for helium versus nitrogen after calcination to 400C (helium permeance 0.002 cm{sup 3}/cm{sup 2}-s-cm Hg). Partial sintering of these membranes resulted in a further reduction in pore size or narrowing of pore size distribution as evidenced by larger separation factors e.g. 9 for helium versus nitrogen (helium permeance 0.0028 cm{sup 3}/cm{sup 2}-s-cm Hg) with only one A2{sup **} coating. Single gas measurements also showed high ideal separation factors for helium versus methane, propylene, sulfur hexafluoride and carbon dioxide. The deposited A2{sup **} membrane was reacted with titanium isopropoxide (Ti(O i-Pr){sub 4}) to improve both its thermal and chemical stability and modify its pore size. This reaction led to an increase in the membrane selectivity to >300 for He versus N{sub 2} below to 120C, and CO{sub 2} versus CH{sub 4}, when measured below 200C. A2{sup **} was also used as a host matrix for preparing imogolite composite membranes that showed molecular sieving behavior.

Recuplex nuclear safety equipment revisions

Description: A number of equipment revisions have been recommended by the Engineering Department for conversion of Recuplex to a manufacturing facility. These revisions include three items affecting the critical mass safety of the solvent extraction system: replacement of the bottom disengagement section of the H-3 stripping column with an always safe unit; replacement of the H-9 and H-10 intercolumn, organic phase surge tanks with always safe tanks; and replacement of the colorimetric plutonium monitors in the aqueous and organic raffinate streams with units insensitive to stream contaminants. This memorandum is intended to clarify the needs for these equipment revisions in achieving a safe and flexible operating system and to indicate the relative effects of revising each of the various equipment pieces separately. The general bases for the present criticality control measures in the solvent extraction system are reviewed briefly prior to discussion of the individual revisions.
