    Abstract: A process is provided that is directed to a steam pyrolysis zone integrated with a solvent deasphalting zone and a hydrotreating zone to permit direct processing of crude oil feedstocks to produce petrochemicals including olefins and aromatics. The integrated solvent deasphalting, hydrotreating and steam pyrolysis process for the direct processing of a crude oil to produce olefinic and aromatic petrochemicals comprises: charging the crude oil to a solvent deasphalting zone with an effective amount of solvent for producing a deasphalted and demetalized oil stream and a bottom asphalt phase; charging the deasphalted and demetalized oil stream and hydrogen to a hydroprocessing zone operating under conditions effective to produce a hydroprocessed effluent reduced having a reduced content of contaminants, an increased paraffinicity, reduced Bureau of Mines Correlation Index, and an increased American Petroleum Institute gravity; thermally cracking the hydroprocessed effluent 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 process for re-refining used lubricating oil (ULO) having thermally unstable additives. ULO is heated by mixing with superheated lubricant boiling range hydrocarbons recovered and recycled from the process. The mixture of ULO feed and superheated hydrocarbons is charged to a vacuum column, producing an overhead vapor free of unstable additives and a residual fraction, containing additives. The overhead vapor is condensed to produce an overhead liquid of lubricant boiling range hydrocarbons, a portion of which is recovered as a product and a portion of which is recycled. The overhead liquid free of unstable additives, may be superheated without fouling to produce superheated fluid which can heat the ULO feed sufficiently to permit fractionation. Superheating may occur in a fired heater or preferably in a heat exchanger to prevent high temperatures and cracking of recycled liquid. Mixing of superheated fluid and ULO feed may occur in a pipe in fully developed turbulent flow, and preferably via an inline mixer. Energy efficiency is improved by heat exchanging ULO feed with product streams.

    Abstract: A method and apparatus for an improved dewatering tank system that allows for safely controlling a water stream exiting the dewatering tank system. The apparatus can include a sound velocity detector, a control system, and a control element. The sound velocity detector can include a transducer, a detector, and a transmitter. The control system can include a computer and a program product. The apparatus can optionally include a dewatering tank, a drain line, and a controllable valve. The apparatus allows for transmitting sound energy through the water stream flowing in the drain lined that is connected to the dewatering tank, calculating the velocity of the sound energy as the sound energy travels through the water stream, monitoring the velocity of the sound energy for a period of time, and controlling the position of the controllable valve depending on the calculated velocity of the sound energy.

    Abstract: Provided are multiple correlations for relationships between MI value for a brightstock extract and the distillation cut point temperature used for separation of the vacuum resid that is used to form the brightstock extract. Based on these correlations, a BSE having a desired MI value can be formed based on an adjustment of the distillation cut point temperature. A first correlation establishes a relationship between a fractional weight boiling temperature for a vacuum resid fraction and a distillation cut point temperature for separating the vacuum resid fraction from at least one distillate fraction in a feedstock. A second correlation establishes a relationship between a fractional weight boiling temperature for a brightstock extract derived from the vacuum resid fraction, and the fractional weight boiling temperature for the vacuum resid fraction. A third correlation has been established between the fractional weight boiling temperature for the brightstock extract and a mutagenicity index value.
