Abstract: Methods and systems are described for treating water in a water system that includes a biofilm with acid-producing bacteria. The biofilm can be treated, reduced, or eliminated by adding chlorite to the water and reacting the chlorite with acid generated by the acid-producing bacteria to form chlorine dioxide. The chlorine dioxide is thus formed in situ localized to the biofilm, and can be effective to kill bacteria in the biofilm.

Abstract: A process for converting C2-5 alkanes to higher value C5-24 hydrocarbon fuels and blendstocks. The C2-5 alkanes are converted to olefins by thermal olefination, without the use of a dehydrogenation catalyst and without the use of steam. The product olefins are fed to an oligomerization reactor containing a zeolite catalyst to crack, oligomerize and cyclize the olefins to the fuel products which are then recovered. Optionally, hydrogen and methane are removed from the product olefin stream prior to oligomerization. Further optionally, C2-5 alkanes are removed from the product olefin stream prior to oligomerization.

The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.

Abstract: Describe are preferred formulations for Avgas meeting the requirements for use in aircraft, including requirements established under ASTM standards and by the Federal Aviation Administration. In one embodiment, a binary mixture of 1,3,5-trimethyl benzene (mesitylene) and isopentane is used to provide a MON of at least 100, and more preferably at least 102. In other embodiments, the amounts of mesitylene and/or isopentane may be changed, and other fuel components are included. These various Avgas formulations are thereby adjusted to meet a variety of requirements as to octane rating, RVP, cold start, and other fuel characteristics.

Abstract: A space-out mechanism that may be used in a tubing hanger system to install a tubing hanger and rigidize the tubing hanger and a casing hanger within a wellhead housing in a single trip is provided. The space-out mechanism may include two pieces that are configured to rotate against each other such that the axial length of the space-out mechanism can be adjusted to remove any axial gaps created in the installation of the tubing hanger or rigidizing of the tubing hanger and casing hanger within the wellhead housing. The two pieces of the space-out mechanism may include a ramp ring and a piston. The ramp ring and piston may each have ramp surfaces that rotate and bear against each other until the system is rigidized.

Abstract: A reduced stroke gate valve is provided. The reduced stroke gate valve provides a predetermined or desired flow area for a given bore size through the gate valve while reducing a total length through which the gate valve strokes between an open position and a closed position. The reduced stroke gate valve includes one or more openings that span a non-circular or non-round area within the gate. The non-circular or non-round shape or distribution of opening(s) in the gate may provide a flow area equivalent to a predetermined flow area for a single circular hole that would otherwise be used for the gate valve application, but with a shape or distribution of opening(s) that provides a reduced stroke length to move the gate valve from the open position to the closed position.

Abstract: A hand-held or portable SPR device focuses light at two or more positions on a noble metal sensor surface, functionalized to enable detection of different SPR curves and their respective minima. The detection is accomplished substantially simultaneously by obtaining SPR signals contemporaneously from the different locations on the sensor surface, on the same sensor. The SPR device may incorporate multiple light sources or a single light source with a beam that is shifted by deflectors in seriatim to focus on different positions on along the functionalized sensor surface. To control wettability of the sensor surface (to augment multiplexing), the sensor surface may include i) the addition of surface assembled monolayers (SAMs) and ii) surface bombardment by gaseous plasmas, most notably O2.
