Title: Heavy aromatics processing
Inventor: MIZRAHI SADI
IPC: C10G35/095
Filed: 1996-02-09
Granted: 2006-09-19
Abstract: A heavy aromatics feed is converted to lighter aromatics products, such as benzene, toluene and xylenes by contacting a C9+ aromatics fraction and benzene and/or toluene over a catalyst comprising a zeolite, such as ZSM-12, and a hydrogenation component, preferably platinum. The catalyst, complete with hydrogenation component, is treated to reduce aromatics loss. Treatment includes exposure to steam and/or sulfur or nitrogen after incorporation of the hydrogenation component. For additional stability and aromatics retention the steamed and/or sulfur treated catalyst is sulfided by cofeeding a source of sulfur. A low hydrogen partial pressure is preferably employed to assist in aromatics retention.

Abstract: An automatic, non-artificially extended, fault surface based horizon modeling method and apparatus produces a final faulted horizon model which is a three dimensional representation of a faulted earth formation including all the horizons and all the faults in response to seismic data, well log data, and fault surfaces and relationships data The horizon modeling apparatus produces the final faulted horizon model by filtering input horizon data and removing bad (wrong-sided) data points.  This is accomplished by: (a) computing intersections between each horizon and each fault that intersects the horizon,  (b) assessing the quality of each intersection,  (c) filtering in the vicinity of the intersection by decreasing the slope between the intersecting fault and its respective horizon,  (d) generating a horizon surface and reassessing their quality, (e) reintroducing the eliminated data points between the fault and the horizon,  (f) re-filtering the reintroduced data points,  (g) generating an initial faulted horizon model,  (h) generating a set of final fault locations, and (i) generating a final faulted horizon model.

The grip element comprises a crimp forming a localized surface deformity which causes the uncoated portion of the tab body to be slightly out of plane surface in the vicinity of the crimp. The thickness of the tab body is between 0.002 and 0.02 inches, and it can be made of either semi-rigid or rigid plastic material. Each of the coated portions is covered by a removable protective liner, and wherein the removable protective liner extends into the uncoated portion.

Abstract: An apparatus has a main conveyor and feed conveyors. The main conveyor is provided with elongate receiving elements that are arranged transversely with respect to their movement path. At feed locations, the circulatory paths of the feed conveyors run over the main conveyor. The feed conveyors have clamps that are spaced apart one behind the other and are driven in circulation in a feed direction. The clamps are adapted to feed the products to the receiving elements and to discharge them to these receiving elements at the feed locations. The clamps are arranged obliquely with respect to their circulatory path. As a result, a straight line running parallel to a clamp-mouth plane and a receiving-element plane, and perpendicular to a longitudinal direction of the clamp mouth, forms an acute angle with the circulatory path.

Abstract: A swath conditioner and mover comprises a frame adapted to travel in a forward direction along the ground with a lower crimping roller rotatably mounted to the frame such that the axis of rotation thereof is at an angle less than ninety degrees to the direction of travel. The lower crimping roller comprises a rough surface suitable for picking a swath from the ground. An upper crimping roller cooperates with the lower crimping roller and is rotatably mounted to the frame above the lower crimping roller. A drive rotates the upper and lower crimping rollers such that the bottom rough surface of the lower crimping roller moves generally forward. The vertical position of the lower crimping roller is substantially parallel and in proximity to the ground such that as the frame travels along the ground, a swath is picked from the ground by contact with the rough surface of the lower crimping roller and is fed between the rollers, and falls back on the ground behind the crimping rollers at a position to one side of its original position. Multiple conditioner movers may be mounted on a single frame to process adjacent swaths. A quick adjustment is provided for the separation between upper and lower rollers.
