  • Patent number: 11724976
    Abstract: An improved process for the recovery of high-purity ethylene-oxide water feed streams to EO purification and MEG reaction units when both are operating in EO plants that incorporate EO Stripper bypass technology, by installing a second lights stripper to exclusively degasify the diluted EO feed to the MEG reactor, thus permitting the use of additional bypassed (gasified) EO absorbate as the diluent and resulting in a substantial increase in the total amount of EO absorbate that can bypass the EO Stripper.

  • Publication number: 20170266635
    Abstract: A reactor design and configuration and a process for the catalytic dehydration of ethanol to ethylene where the reactor train is comprised of a multi-stage single reactor vessel or multiple reactor vessels wherein each stage and/or vessel has different length, internal diameter, and volume than the other stages and/or vessels and in addition the stages and/or reactor vessels are connected in series arrangement, preferably used with an improved means of introducing the ethanol feedstock and a heat carrying inert gas to the improved reactor train. The inert gas is heated in a separate furnace from the ethanol feed and then injected into the ethanol feed to supply the heat of reaction.

  • Patent number: 6597799
    Abstract: A method and apparatus for analyzing a picture of an effluent such as a smoke plume or dust cloud to determine the opacity of the effluent. The picture of the effluent is first broken down into pixels. Each pixel corresponding to the effluent is identified and the color of each effluent pixel is analyzed to calculate the opacity of that effluent pixel. An opacity value for the entire effluent is extrapolated based on the opacity values of each effluent pixel.

  • Patent number: 5748692
    Abstract: A shielded rack loader makes use of a loading rack movable between a shielding structure and a storage tube. A shield plug seals the storage tube. A hoist moves the shield plug and the loading rack. A shield plug cart and a material transfer cart mate with receiving flanges of the rack loader and permit temporary storage and movement of the shield plug and of canisters of transuranic material.

  • Patent number: 4522511
    Abstract: Method and apparatus for measuring radiant energy, particularly relatively high energy levels of coherent radiation, in which the energy impinges upon an absorber surface, the energy transferred from the absorber surface to a fluid coolant in thermal association with the absorber surface, and the energy carried away by the coolant measured by means of a temperature difference measuring device, preferably a thermopile, positioned in thermal contact with a portion of the inlet leg of the coolant conduit and the outlet leg thereof, in order that high energy levels may be measured at a cool absorber surface while flowing relatively small amounts of heat energy through the temperature difference measuring means.
