Publication number: 20200191762Abstract: Measuring the real corrosion risk that organosulfur compounds present in refinery operations is simplified by first measuring the total sulfur content of a sample of a hydrocarbon material. The sample is then combined with a specific quantity of high surface area iron powder at a temperature representative of the highest temperature anticipated in a refining process for a period of time, such as one hour. The solid phase is then removed, and the total sulfur content is again measured. The difference between the before and after represents the total reactive sulfur of the hydrocarbon material. The hydrocarbon material is then blended with other hydrocarbon materials to create a stream that can be optimized to utilize the maximum volume of the lowest cost feedstock while managing the corrosion risk to the refinery equipment and piping.Type: ApplicationFiled: December 12, 2019Publication date: June 18, 2020Applicant: PHILLIPS 66 COMPANYInventors: Ricky E.

Patent number: 8475649Abstract: Methods and apparatus relate to processing of petroleum with a bed having a sorbent based diluent that the petroleum contacts upon passing through the bed. Magnetic properties of the sorbent and any other material, such as zeolite, used in the bed enable separation of such bed constituents based on a sulfided form of the sorbent being magnetic in contrast to a non-sulfided form of the sorbent being non-magnetic. Dividing the bed constituents into first and second portions by magnetic separation facilitates in selective replacing and/or regenerating the first portion independent of the second portion.Type: GrantFiled: August 8, 2012Date of Patent: July 2, 2013Assignee: Phillips 66 CompanyInventors: Sundararajan Uppili, Donald R.

Patent number: 5048333Abstract: An apparatus and method for determining the level of material within a rotating cylindrical vessel are disclosed in which a rigid member means on the interior of the rotating vessel is fixedly secured to a rod having a longitudinal axis parallel to the rotational axis of the rotating vessel, and wherein the rod extends through one end wall of the vessle to the exterior at which it is fixedly secured to an indicator means. The rigid member means within the vessel is capable of resting at the top surface of the material within the vessel. As the level of material within the vessel is raised or lowered the rigid member means will rotate, thus causing an equal rotation of the rod and the indicator means on the exterior of the vessel. By monitoring the position of the indicator means, the level of material within the vessel can be determined.Type: GrantFiled: October 15, 1990Date of Patent: September 17, 1991Assignee: Phillips Petroleum CompanyInventors: Ralph E. Bonnell, Donald R. Engelbert
