Abstract: Systems and methods are provided for conversion of oxygenate feeds to distillate boiling range products using multiple moving bed reactor stages. The systems and methods allow for multiple stages to be used while avoiding the need for distillation or other boiling point based separation as the mixture of feed and effluent is passed between stages. Instead, a stripping gas is used to disengage the feed and effluent from the catalyst solids. In combination with an improved moving bed reactor design, this can allow substantially all of the feed and effluent from a first moving bed reactor stage to be passed into a second moving bed reactor stage, even when the feed and effluent include both vapor and liquid phase portions.

Abstract: A refractory-lined equipment includes a vessel defining an interior at least partially lined with a refractory material, and a nozzle assembly coupled to the vessel and extending into the interior. The nozzle assembly includes an outer sleeve fixed to the sidewall and extending through an aperture defined in the sidewall, the outer sleeve defining a central passageway, and a nozzle cartridge assembly positionable within the central passageway and including an inner sleeve, a refractory lining disposed about the inner sleeve, and a nozzle positioned within the inner sleeve. The nozzle cartridge assembly is removably coupled to the outer sleeve external to the vessel.

Abstract: A method for producing a blended jet boiling range composition stream may include: oligomerizing an ethylene stream to a C4+ olefin stream in a first olefin oligomerization unit, wherein the C4+ olefin stream contains no greater than 10 wt % of methane, ethylene, and ethane combined; wherein the ethylene stream contains at least 50 wt % ethylene, at least 2000 wppm ethane, no greater than 1000 wppm of methane, and no greater than 20 wppm each of carbon monoxide and hydrogen; oligomerizing the C4+ olefin stream and a propylene/C4+ olefin stream in a second oligomerization unit to produce an isoolefinic stream; subjecting at least a portion of the isoolefinic stream to a hydroprocessing process with hydrogen as treat gas to produce an isoparaffinic stream having no greater than 10 wt % olefin content; and using least a portion of the isoparaffinic stream to create the blended jet boiling range.

Abstract: Systems and methods are provided for using molten carbonate fuel cells (MCFCs) to reduce, minimize, and/or avoid CO2 emissions in a marine vessel environment. The systems and methods can include operation of MCFCs on a marine vessel under high fuel utilization conditions in order to provide power and capture CO2. The high fuel utilization conditions can allow for mitigation of CO2 over extended periods of time in spite of the challenges of performing CO2 mitigation in a potentially isolated environment such as a marine vessel. Additionally, the high fuel utilization can also reduce or minimize exhaust of fuels, such as methane, to the environment.

Abstract: A plunger lift system, as well as a method for monitoring plunger parameters within a wellbore using such a plunger lift system, are provided. The plunger lift system includes a lubricator attached to a wellhead at the surface and a plunger dimensioned to travel through the production tubing upon being released from the lubricator. The plunger lift system also includes magnetic sensor systems installed along the production tubing, where each magnetic sensor system includes a magnetic sensor for detecting the passage of the plunger as it travels through the production tubing, as well a communication device for transmitting communication signals between the magnetic sensor systems and a computing system located at the surface, where the computing system includes a processor and a non-transitory, computer-readable storage medium including computer-executable instructions that direct the processor to dynamically determine the plunger position and/or velocity based on the received communication signals.

Abstract: In various aspects, molten carbonate fuel cell configurations are provided that include a reforming catalyst and alkali traps integrated with one or more structures within the anode gas-collection volume. The purpose of the reforming catalyst is to reform methane (or some other reformable fuel) into hydrogen. In operation, alkali metals may migrate from the fuel cell electrolyte into the anode. Unless trapped, the alkali metals may deactivate the reforming catalyst. The alkali trap prolongs the operating life of reforming catalyst within the anode volume by capturing some portion of the alkali metal in the anode gas-collection volume. This reduces an amount of alkali metal that interacts with the reforming catalyst in the anode gas-collection volume. The prolonged life of the reforming catalyst prevents a decrease in catalyst activity.

Abstract: Compositions are provided that include at least a portion of an isoparaffinic blend component, an iso-olefinic blend component, or a combination thereof, along with a method for making such a blend component. The highly isoparaffinic and/or iso-olefinic nature of the blend component can allow a blend component to be used in combination with both conventional/mineral fractions as well as non-traditional feeds to form fuel fractions and/or fuel blending component fractions. Examples of fuels that can be formed by making a blend that includes an isoparaffinic and/or iso-olefinic blend component include diesel fuels, marine gas oils, and various types of marine fuel oils, such as very low sulfur fuel oils.
