Abstract: A computer system including a memory, at least one processor coupled to the memory, and a search component executable by the at least one processor is provided. The search component is configured to receive information descriptive of at least one search term; execute a first query against a plurality of documents that identifies at least one first document of the plurality of documents responsive to the at least one search term; identify one or more secondary terms associated with the at least one first document based on occurrence of the one or more secondary terms within the at least one first document; and provide a search result including at least one of the one or more secondary terms and one or more identifiers of one or more documents including the one or more secondary terms. The search result may also include one or more identifiers of bookmarked documents.

Abstract: There is described a novel tool and method for the isolation and pressure-testing of connections, such as welds, between a vessel and a nozzle or branch pipe. The nozzle testing tool comprises an improved seal that expands into sealing contact as testing pressure is increased. The tool can also be easily adjusted in order to accommodate variations in nozzle configuration.

Abstract: A process flow sequence for the reduction of polymer fouling while maintaining efficient production levels wherein a dual pressure, dual column configuration is used to effect the reduction in polymer fouling. The dual pressure, dual column configuration of the invention uses a high pressure and a separate low pressure to isolate the desired fractions while effecting a reduction in the production of fouling polymers.

Abstract: A process sequence for treating cracked gases of heavy feedstocks which preferentially produces propylene to the exclusion of propane, butanes and butenes. The process eliminates the need for a depropanizer with the attendant savings in capital and operating costs. In lieu of a conventional C3 splitter, the process features a depropylenizer, i.e. a distillation tower designed to separate propylene from propane, butanes and butenes. A hydrogenation unit to eliminate contaminants can be placed upstream of the depropylenizer or the depropylenizer can be split into two sections with the hydrogenation unit located between the two sections.
