Patent number: 5034119Abstract: Non-carcinogenic bright stock extracts and/or deasphalted oils are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the bright stock extract or deasphalted oil and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic bright stock extracts and/or deasphalted oils are then processed utilizing the conditions so established. A bright stock extract and a deasphalted oil substantilly free from mutagenic activity, as well as processes for their production are also provided herein.Type: GrantFiled: March 28, 1989Date of Patent: July 23, 1991Assignee: Mobil Oil CorporationInventors: Gary R.

Patent number: 4993603Abstract: A food storage container for dry or liquid foods and other open air perishable products provides a substantially liquid-tight seal when the lid is in a closed position and easy pouring of contents when in the open position. The container is easy to open, employing a rocker points placed off-center of the container lid's centerline to allow for a rocking action effective to release the lid from a closed position when a downward force is exerted upon an upper surface of the lid thereby providing an effective opening for pouring. A substantially liquid-tight seal is achieved through the use of a plug section of the lid having a continuous outer peripheral surface which effects a close conforming fit with a similarly positioned surface area on the container body in a continuous and positive manner.Type: GrantFiled: January 12, 1990Date of Patent: February 19, 1991Assignee: Mobil Oil CorporationInventor: Marlan H.

Patent number: 4974677Abstract: A process for selectively plugging zones of high permeability within an oil-bearing subterranean formation. The process of the present invention comprises the steps of injecting into the formation a high temperature selective gel-forming composition comprising an aqueous solution of a high molecular weight polyacrylamide having 30 percent or less hydrolysis, and an effective amount of a crosslinking agent which is a mixture of a phenolic component and an aldehyde, and gelling the solution in-situ by thermally reacting said gel-forming composition at a temperature effective to promote gelation. The resultant gel is exceptionally thermally stable and, therefore, can be used as an effective profile control agent in all thermal enhanced oil recovery operations, including steam flooding. Also provided is a process for recovering oil from a subterranean oil-bearing formation.Type: GrantFiled: October 16, 1989Date of Patent: December 4, 1990Assignee: Mobil Oil CorporationInventor: Paul Shu

Patent number: 4964296Abstract: A liquid leak detector for above-ground tanks includes an upright standpipe connected to the tank so that the standpipe can be filled with liquid from the tank to the same level as the liquid in the tank. A pressure transducer is connected between the bottom of the tank and the bottom of the standpipe to measure the difference in pressure of the liquids in the tank and standpipe. Any change in the liquid pressure at the bottom of the tank as a result of leakage from the tank will change the pressure differential on the pressure transducer. This changes the output of the transducer which can be recorded to indicate leakage from the tank.Type: GrantFiled: September 28, 1989Date of Patent: October 23, 1990Assignee: Mobil Oil CorporationInventor: Jay E. Jensen
