    摘要： A process is described for producing deasphalted steam cracker tar comprising feeding steam cracker tar to a vacuum pipestill (VPS) including a flash zone separated from a zone comprising trays by at least one annular entrainment ring and obtaining as an overheads a deasphalted tar product and as a bottoms an asphaltenic heavy tar product. Also according to the invention, there is a system for the upgrading of tar comprising said VPS with at least one annular entrainment ring.

    摘要： The invention is directed to a process wherein a feedstock or stream comprising steam cracker tar is passed to a vacuum pipestill. A deasphalted cut of tar is obtained as an overhead (or sidestream) and a heavy tar asphaltenic product is obtained as bottoms. In preferred embodiments, at least a portion of the bottoms product is sent to a partial oxidation unit (POX) wherein syn gas may be obtained as a product, and/or at least a portion of the bottoms product is used to produce a light product stream in a coker unit, such as coker naphtha and/or or coker gas oil. In another preferred embodiment at least a portion of the overheads product is added to refinery fuel oil pools and in yet another preferred embodiment at least a portion of the overheads product is mixed with locally combusted materials to lower soot make. Two or more of the aforementioned preferred embodiments may be combined.

    摘要： The invention relates to a method for processing asphaltene-containing feed to a pyrolysis furnace by raising the final boiling point of the feed/steam mixture to the pyrolysis furnace to ensure fouling occurs lower in the convection section where the mixture of air and steam can burn off fouling deposits during decoking operations. The final boiling point of the feed stream is increased by adding a heavy essentially asphaltene-free high boiling point hydrocarbon to the feed stream before the feed stream enters the convection section of the pyrolysis furnace, whereby said fouling occurs lower in the convection section.

    摘要： A process for cracking hydrocarbon feedstock containing resid comprising: heating the feedstock, mixing the heated feedstock with a fluid and/or a primary dilution steam stream to form a mixture, flashing the mixture to form a vapor phase and a liquid phase which collect as bottoms and removing the liquid phase, separating and cracking the vapor phase, and cooling the product effluent, wherein the bottoms are maintained under conditions to effect at least partial visbreaking. The visbroken bottoms may be steam stripped to recover the visbroken molecules while avoiding entrainment of the bottoms liquid. An apparatus for carrying out the process is also provided.
