20130112594 | PRODUCTION OF LOW CLOUD POINT DISTILLATES - Systems and methods are provided for producing at least one low sulfur distillate fuel product with improved low temperature properties. A potential distillate fuel feed is initially hydrotreated to reduce sulfur and nitrogen levels in the feed to desired amounts. The hydrotreated effluent is then fractionated to form several fractions, including a light diesel/distillate fraction and a heavy diesel fraction. The heavy diesel fraction is then dewaxed to improve the cold flow properties of the heavy diesel fraction. The dewaxed heavy diesel fraction can be combined with the light diesel fraction, or the dewaxed heavy diesel fraction can be fractionated as well. Optionally, the heavy diesel fraction is dewaxed under conditions effective for producing a dewaxed fraction with a cloud point that is less than or equal to the cloud point of the light diesel/distillate fraction. | 05-09-2013 |
20140061024 | DISTILLATION TOWER FEED DEVICE - A feed device for a distillation tower or column with a flash zone, wash zone and stripping zone has an annular, open-bottomed channel located around the periphery of the feed zone of the tower with an inner wall spaced from the inner curved wall of the tower and a top covering the channel to confer a generally inverted-U shape to the cross section of the channel. One or more tangential feed inlets are provided to admit a heated, mixed phase feed to the tower and direct the feed into and along the channel. One or more vapor scoops are provided for each feed inlet with the scoop(s) located on the inner wall of the channel, each at a sufficient distance along the channel from the inlet to permit cyclonic separation of vapor and liquid to take place before the vapor in the feed from the inlet enters the scoop(s) and passes through a vapor exit port into the central core of the tower. The tower is preferably used with a radial louvre baffle at the top of the stripping zone. | 03-06-2014 |
20140294040 | METHOD AND SYSTEM FOR DETECTING DEPOSITS IN A VESSEL - Systems and methods for detecting a deposit in a vessel with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the vessel. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and media exposed to the sensing cable. An optical signal interrogator is adapted to receive a signal from a plurality of sensor locations and configured to measure, a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to detect a deposit by determining one or more properties of the one or more media exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto. | 10-02-2014 |
20140294041 | METHOD AND SYSTEM FOR DETERMINING FLOW DISTRIBUTION THROUGH A COMPONENT - Systems and methods for determining the flow distribution of a fluid through a component with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the component. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and the fluid exposed to the sensing cable. An optical signal is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to determine a flow of the fluid by determining one or more properties of the fluid exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto. The present invention can be effective in accurate and high spatial resolution of flow distributions through vessel components, such as a particulate bed (such as a reactor catalyst bed), a wash bed including packing material, an absorbent bed, a structured bed, a filter, or the like. | 10-02-2014 |
20140311953 | METHOD TO OPTIMIZE RUN LENGTHS AND PRODUCT QUALITY IN COKING PROCESSES AND SYSTEM FOR PERFORMING THE SAME - System to detect coking in at least one component of refinery equipment is provided. The system includes a fiber optic assembly having at least one optical fiber operably coupled with the component, the fiber optic assembly further including a light source to transmit light having a known parameter through the optical fiber and a receiver to receive the light from the optical fiber, and a processor in communication with the fiber optic assembly to identify a shift in the parameter received by the receiver, the shift corresponding to an operating characteristic of the component. Method also provided for detecting coking using the system to detect coking disclosed herein. | 10-23-2014 |
