Abstract: A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

Abstract: Method and apparatus for depositing a chemical over a body of water. In one embodiment the invention includes collecting and concentrating a floating contaminant between two floating booms pulled by one or more surface vessels. The booms define an aperture intermediate of their endpoints, and the towing of the boom results in the flow of concentrated contaminant through the aperture. One or more nozzles proximate the aperture deposit a chemical, such as a liquid dispersant, on the contaminant and water flowing through the aperture. Some embodiments also include a mixing apparatus placed at aft of the aperture for inducing mixing of the deposited chemical and the floating contaminant.

Abstract: Provided in accordance with the present invention, is a preferred embodiment of a boom for use in or containing, concentrating, and burning oil on the surface of a body of water. The boom includes a series of flotation sections, having an average density substantially less than that of water for providing flotation. The boom also includes a water distribution system at least partially surrounding one or more flotation sections. The water distribution system includes material substantially permeable to the water, for receiving, absorbing, and distribution of the water for heat protection. The boom additionally includes a pressurized fluid system/structure for placing the water distribution system in fluid communication with a supply of pressurized water. The pressurized fluid system includes at least one fluid conduit, extending for substantially the length of the boom. The conduit includes an end adapted for connecting to an external source of pressurized water.

Abstract: A combined skirted oil-sorbing boom and oil-sorbing sweep has a buoyant inner core and an oil-sorbent outer core of a spirally wound sheet of polymeric, oleophilic, hydrophobic microfibers. Adhesively bonded to a sheet of the microfibers at the outer face of the outer core is an open-mesh netting of polymeric monofilaments that are fused at their crossings. The netting and the sheet to which it is adhered extend from the outer core to form a depending skirt which acts as a barrier to oil that is being sorbed by the microfibers. The buoyant inner core can be an open-cell foam that sorbs oil slowly, thus supplementing the oil-sorbing capability without significant loss of freeboard.
