  • Patent number: 11591527
    Abstract: Provided are novel process for upgrading naphtha and increasing the yield of reformate. Olefinic naphtha and light paraffins are combined and fed to a catalytic fluidized bed reactor maintained at a temperature about 775° F. and about 1250° F. and an operating pressure between about 10 psig and about 500 psig to produce a product comprising at least 1 wt. % higher C5+ hydrocarbon than the combined feed and at least 55 wt. % aromatics.
    Type: Grant

  • Publication number: 20210215653
    Abstract: A method for estimating a gas concentration of a compound of interest within a process vessel for permitting safe entry into the process vessel comprises: exposing the process vessel to a condensing fluid to dissolve gases therein; collecting liquid comprising the condensing fluid from a location downstream of the process vessel; sealing the liquid in a sample container to yield a condensate sample; measuring and/or calculating properties of a liquid portion and a gas portion of the condensate sample; calculating a process vessel condensate density; determining a thermodynamic equilibrium correction factor; calculating the gas concentration of the compound of interest in the process vessel based on the properties of the condensate sample, a thermodynamic equilibrium correction factor, the process vessel condensate density, and optionally, a safety factor; and determining when the calculated gas concentration of the compound of interest in the process vessel permits safe entry into the process vessel.

  • Publication number: 20210147753
    Abstract: A method for upgrading olefin-containing naphtha can include injecting a hydrocarbon stream containing an olefin-containing naphtha comprising olefins and diolefins in a reforming reactor at temperatures of from about 700° F. to about 1200° F. and pressures of from about 10 psig to about 500 psig to produce a reformate stream, which is then contacted with an atmosphere comprising hydrogen in a hydrotreating reactor to produce a product stream, wherein the reformate stream comprises at least 50% less diolefins than the hydrocarbon stream and the product stream comprises at least 99% less diolefins than the hydrocarbon stream. A system for upgrading olefin-containing naphtha may include a reforming reactor configured to receive a hydrocarbon stream containing an olefin-containing naphtha comprising olefins and diolefins, which produces a reformate stream, and a hydrotreating reactor configured to receive the reformate stream.
