Abstract: A process is provided that is directed to a steam pyrolysis zone integrated with a hydrotreating zone and a solvent deasphalting zone to permit direct processing of crude oil feedstocks to produce petrochemicals including olefins and aromatics. The integrated hydrotreating, solvent deasphalting and steam pyrolysis process comprises charging the crude oil to a hydroprocessing zone to produce a hydroprocessed effluent; charging the hydroprocessed effluent to a solvent deasphalting zone to produce a deasphalted and demetalized oil stream and a bottom asphalt phase; thermally cracking the deasphalted and demetalized oil stream in the presence of steam to produce a mixed product stream; separating the mixed product stream; purifying hydrogen recovered from the mixed product stream and recycling it to the hydroprocessing zone; recovering olefins and aromatics from the separated mixed product stream; and recovering pyrolysis fuel oil from the separated mixed product stream.

Abstract: A solar distillation device and method of constructing same are disclosed. The device employs a fluid flow surface for controlling the thickness of a flowing, laminar fluid (i.e., seawater in preferred embodiments) film. The fluid is deposited on an upper end of the flow surface where a relatively thick layer forms. The fluid flows over a fluid dispersal region and then over an active region where the surface area is designed to control the fluid film thickness for maximum evaporation. An outer domed surface surrounds the fluid flow surface and may enhance the heating effect from the sun.

Abstract: A process for producing mesophase pitch using a long tube reactor is disclosed. An aromatic rich feed, preferably a petroleum pitch having a softening point above 100° C., is preheated to a temperature above its softening point and mixed with a vapor, preferably steam, in a long tubular reactor under intense mixing conditions, preferably fully developed turbulent flow such as mist annular flow, with a residence time at least an order of magnitude less than prior art processes and preferably less than 10 seconds. Preferably the reactor is heated by electric resistance or induction heating or by immersion in a heated fluid or in a fired heater. Mesophase pitch with a high coking value and a surprisingly low quinolone insoluble content is produced. The byproducts of thermal polymerization and thermal dealkylation have less than 50% as much olefin and diene content as compared to similar byproducts from prior art processes.

Abstract: A method of reducing residual hydrocarbon accumulation during processing can comprise forming a permeable body (608) of a comminuted hydrocarbonaceous material within an enclosure (602). A primary liquid collection system (610) is located in a lower portion of the permeable body. The primary liquid collection system (610) has an upper surface for collecting and removing liquids. Comminuted hydrocarbonaceous material below the primary liquid collection system (610) forms a non-production zone (616). At least a portion of the permeable body (608) is heated to a bulk temperature above a production temperature sufficient to remove hydrocarbons therefrom within a production zone (614), where conditions in the non-production zone (616) are maintained below the production temperature.

Abstract: Disclosed are examples of apparatuses for evaporative purification of a contaminated liquid. In each example, there is a vessel for storing the contaminated fluid. The vessel includes a surface coated with a layer of superhydrophobic material and the surface is at least partially in contact with the contaminated liquid. The contaminants do not adhere to the surface as the purified liquid evaporates, thus allowing the contaminants to be harvested.
Abstract: The inventive technology may involve, in particular embodiments, novel use of a non-porous, high surface energy stationary phase to adsorb, in reversible fashion, the most polar component of a resins fraction of an input hydrocarbon when a mobile phase is passed over the stationary phase. Such reversible adsorption prevents irreversibly adsorption of such components on active stationary phase(s) downflow of the non-porous, high surface energy stationary phase, thereby conserving stationary phase costs and increasing resolution of resins elutions, and accuracy of hydrocarbon component results. Aspects of the inventive technology may also involve a novel combination of a solubility based asphaltene component fractionating and analysis method and an adsorption chromatography method for separating and/or analyzing saturate, aromatics and resins components of an input hydrocarbon.

Abstract: A method for evaporation and possibly distillation of liquids by means of a heat pump is provided. By using a heat pump (2), energy is taken from energy reservoir(s) (1) such as rivers, sea water, air, or ground heat. However, it is difficult to obtain temperatures high enough to evaporate water at atmospheric conditions. According to the invention, low temperature heat is utilized by means of a heat pump by using the condenser of the heat pump to evaporate liquids in an evaporator (4?) at a pressure lower than atmospheric pressure, and thus at a lower evaporation temperature. Furthermore, the saturation of the evaporated liquids is eliminated before the evaporated liquids enter the compressor (10) by the further heating of the evaporated liquids leaving the liquids evaporator (4?) in a heat exchanger (11) that utilizes the peak temperature of the refrigerant that leaves the heat pump's refrigerant compressor (3).

Abstract: A de-header valve can include a flushing system for flushing undesirable material from the upper and lower bonnets while the de-header valve is opened. The flushing system can include three valves. A first valve controls the flow of steam to the de-header valve. A second valve controls the flow of water for flushing the bonnets. A third valve controls how the bonnets are drained. The third valve can be a three way valve that allows the bonnets to be drained to a pit during flushing, and also allows steam condensate to drain into a steam trap.
