Publication number: 20170266635Abstract: 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.Type: ApplicationFiled: March 24, 2017Publication date: September 21, 2017Applicant: Petron Scientech, Inc.Inventors: Yogendra Sarin, Brian Ozero, Frank Liotta, Hassan Taheri

Patent number: 6597799Abstract: 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.Type: GrantFiled: June 19, 2000Date of Patent: July 22, 2003Assignee: Scientech, Inc.Inventors: William P. Pfaff, Jay Stretch

Patent number: 5748692Abstract: 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.Type: GrantFiled: November 30, 1995Date of Patent: May 5, 1998Assignee: Scientech Inc.Inventor: Harold M. Burton
