  • Patent number: 10543475
    Abstract: Producing C5 olefins from steam cracker C5 feeds may include reacting a mixed hydrocarbon stream comprising cyclopentadiene, C5 olefins, and C6+ hydrocarbons in a dimerization reactor where cyclopentadiene is dimerized to dicyclopentadiene. The dimerization reactor effluent may be separated into a fraction comprising the C6+ hydrocarbons and dicyclopentadiene and a second fraction comprising C5 olefins and C5 dienes. The second fraction, a saturated hydrocarbon diluent stream, and hydrogen may be fed to a catalytic distillation reactor system for concurrently separating linear C5 olefins from saturated hydrocarbon diluent, cyclic C5 olefins, and C5 dienes contained in the second fraction and selectively hydrogenating C5 dienes. An overhead distillate including the linear C5 olefins and a bottoms product including cyclic C5 olefins are recovered from the catalytic distillation reactor system.

  • Patent number: 10538465
    Abstract: Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins, but has not been implemented commercially partially due to the unstable nature of hydrocarbon/oxygen mixtures, and partially due to the cost involved in the construction of new facilities. An oxidative dehydrogenation chemical complex designed to reduce costs by including integration of an oxygen separation module that also addresses safety concerns and reduces emission of greenhouse gases is described.

  • Patent number: 10493395
    Abstract: The invention relates to an apparatus and to a method for separating condensable materials from an exhaust air stream. Known apparatuses of this type typically comprise a flow duct for the correspondingly contaminated exhaust air, wherein a first separator (114) and a second separator are connected in series in the flow duct (110). A fan is typically connected downstream of the two separators and operates as a suction fan in order to draw the exhaust air through said separators and to discharge the exhaust air to the environment after it has passed through both separators. In a rolling mill, order to observe predefined limit values for the proportion of condensable materials in exhaust air streams before such streams are discharged into the ambient air, the present invention provides for the exhaust air to be separated at the rolling mill itself, and, downstream, for the fan to be placed not at the outlet of the separators but upstream of the first separator.
