Evaluation of Effectiveness of the Turco Low Profile Turbulator Reg Sign
This document discusses a turbulator which utilizes a heated chemical bath to reduce smearable contamination from small parts and tools. It is comprised of two agitators programmed to automatically alternate the flow of the cleaning solution within the tank in four separate and distinct high velocity flow patterns allowing access to the entire surface area of the part or tool being decontaminated. The turbulator is being evaluated to determine if agitation increases the effectiveness of waste minimization. Testing of the turbulator consisted of evaluation of the Sludgetrap Containment, Tool Cleaning Demonstration, and Coupon Testing. Results so far are that the sludgetrap is effective in containing particles the size of sand, agitation increases the effectiveness of the turbulator, abrasives can replace detergents for waste minimization, and Inconel 625 is more difficult to clean than Type 3041 Stainless Steel.

Enzymatic desulfurization of coal
Our experimental approach focuses on the use of enzymes which catalyze the addition of oxygen to organic compounds. In tailoring the application of these enzymes to coal processing, we are particularly interested in ensuring that oxidation occurs at sulfur and not at carbon-carbon bonds. Previous studies with DBT have shown that the reaction most frequently observed in microbial oxidative pathways is one in which DBT is oxidized at ring carbons. These reactions, as we have said, are accompanied by a considerable decrease in the energy content of the compound. In addition, microbial pathways have been identified in which the sulfur atom is sequentially oxidized to sulfoxide, to sulfone, to sulfonate, and finally to sulfuric acid. In this case, the fuel value of the desulfurized compounds is largely retained. We are evaluating the potential of commercially available enzymes to perform this function.

Liquid Phase Methanol Laporte Process Development Unit: Modification, Operation, and Support Studies
The objectives of this program are to implement and test the process improvements identified through the engineering studies of the current program to demonstrate the capability of long-term catalyst activity maintenance, and to perform process and design engineering work that can be applied to a scaled-up Liquid Phase Methanol (LPMEOH) facility. An optional series of PDU runs is offered to extend the testing of the process improvements. A parallel research program will be performed to enhance the LPMEOH technical data base to improve the likelihood of commercialization of the LPMEOH process. Activities this quarter include: Flow sheet development for La Porte PDU modifications continues. A preliminary P ID review was completed and flow sheet modifications were identified and are being incorporated. A preliminary hazards review was completed on 22 May. Some minor flow sheet modifications resulted and a number of action items were identified. The most significant action item is to develop a materials reactivity and compatibility grid for the different alcohols, ethers, and esters which will be produced at the PDU. Heat and material balances were completed for the maximum production case of the mixed DME/MEOH synthesis campaign. An improved rate expression was developed. 1 fig.

Development of an advanced, continuous mild gasification process for the production of coproducts
Research continued on the production of coproducts from continuous mild gasification. During the third quarter of 1990, work focused on start-up and operation of the 50 pound/hour char-to-carbon (CTC) process research unit (PRU). Start-up procedures have been finalized for the methane production reactor, and the design temperature has been achieved. Flows and pressures for the overall process have been balanced and optimized. We have achieved temperatures above 1500{degree}F in the carbon formation reactor. Upgrading experiments on mild gasification pitch have also continued on a pitch produced in run MG-122. Results of heat treating and catalytic treating tests are reported.

Motion control of the accumulator flying wires
Flying wire systems for the Fermilab Accumulator are being constructed in order to measure the transverse beam profiles during stacking. Each device passes a 25 micron carbon filament through the beam transversely at a constant velocity of 10 m/s. Collisions between the beam particles and the wire produce secondary particle cascades, which in turn produce photons in a scintillator. A photomultiplier tube is used to measure the light intensity while the wire position is determined by an optical encoder. There are six Accumulator flying wire systems. Four of them are to be used in normal stacking operation: two horizontal and two vertical flying wires are in the AP40 high dispersion section, covering the core orbit and the extraction orbit respectively. The other two horizontal wires are for measuring the momentum distribution of the beam on the central orbit at the Accumulator transition energy. At the AP40 high dispersion region a wire covers the central orbit, the other is in the AP30 low dispersion section. The operation and control of the flying wire system is discussed in this paper. 11 figs.
