Abstract: A direct electrical heating flow system (100) includes at least one flow pipe (20) and at least one cable (120) disposed along the at least one flow pipe (20) for heating and/or monitoring the at least one flow pipe (20). The cable (120) includes an inner conductive region (180) surrounded by an annular insulating region (190, 200) and peripheral thereto an outer annular conductive region (210). The inner conductive region (180) encloses an optical fibre waveguide region (160) including at least one optical fibre waveguide (150) for conveying at least one information-bearing signal.

Title: Pitch composition
Inventor: MCGEHEE JAMES F
IPC: C08L95/00
Filed: 2010-06-16
Granted: 2014-02-11
Abstract: A composition is produced from converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.

Title: Dual polymer system for water recovery and separation of suspended solids from aqueous media
Inventor: NICHOLS EVERETT J
IPC: C08J3/20
Filed: 2010-07-06
Granted: 2019-09-03
Abstract: A method uses anionic and cationic polymers added in, any order or simultaneously, to aqueous media for the removal of substances. The sequential addition of the two biopolymers, anionic xanthan, followed by cationic chitosan, causes the rapid formation of very large and cohesive fibrillar aggregates that may exhibit high solids to liquid ratios and that quickly settle out from the aqueous media. The aqueous media can be easily separated from the large fibrillar aggregates by settling under gravity or by filtration through a porous containment device, such as a synthetic or non-synthetic woven or non-woven fabric including a geotextile fabric or a solid containment device containing a solid mesh screen.
