  • Recovery of acetophenone during the production of phenol
    Patent number: 8530702
    Abstract: A method for producing acetophenone comprising: treating one or more alkylbenzenes comprising s-butylbenzene to produce a feed comprising phenol and acetophenone; separating a crude phenol stream from the feed under crude phenol separation conditions effective to produce a crude phenol heavies; and, separating an acetophenone stream directly from the crude phenol heavies under azeotropic distillation conditions.
    Type: Grant
    Filed: October 23, 2008
    Date of Patent: September 10, 2013
    Assignee: Shell Oil Company
    Inventors: Jesse Raymond Black, Larry Wayne Payne, Phillip Edward Unger

  • Method of making high purity phenol
    Patent number: 7205442
    Abstract: A method of manufacturing a phenol product having a reduced concentration of a contaminating reaction by-product. The method includes contacting a phenol stream, having a concentration of the contaminating by-product, by contacting the phenol stream with an acidic catalyst under suitable purification reaction conditions. Also included is a composition comprising a sec-butyl benzene derived phenol product that has been purified by the removal of certain undesirable reaction by-products.
    Type: Grant

  • Method of purifying phenol
    Patent number: 7019180
    Abstract: A method of purifying a phenol stream that contains a concentration of a contaminating compound is provided. The phenol stream is treated or purified by contacting the stream, under suitable process conditions, with a treatment catalyst that has a low silica content but comprises alumina and a Group VIA metal.

  • System and method of surfactant dosing
    Publication number: 20030213069
    Abstract: A system and method of processing laundry by the determination of surface tension in a dynamic environment for surfactant concentration in industrial laundry applications. The dosage system is able to control the surfactant concentration for a recycle wash tank and preferentially the washer tank using surface tension measurements, temperature control, and correlation to the percentage of active matter based on a full dose of a commercial surfactant for the wash runs. The dosage system preferably uses a surface tensiometer able to monitor surfactant levels and to constantly dose surfactant for use in subsequent washes.
