Patent number: 4324527Abstract: A centrifugal pump adapted for use in a fermentor is provided.

Patent number: 4216193Abstract: A method is provided for producing a carbon black with a tint residual below -6. The method entails introducing feedstock axially and generating a hot combustion gas vortex in a cylindrical precombustion section of a tubular carbon black reactor, producing a first mixture of feedstock and combustion gases, passing the mixture through an abruptly restricted passage axially connected to the precombustion section, abruptly expanding the first mixture into a frustoconical venturi converging section of the reactor with mixing of this first mixture with an additional flow of combustion gas at the exit of the converging section with the combustion gas entering the converging section in opposite, radial flow thereby forming a second mixture which is admitted into a reaction section of the carbon black reactor.Type: GrantFiled: May 4, 1978Date of Patent: August 5, 1980Assignee: Phillips Petroleum CompanyInventors: John W. Vanderveen, King L. Mills

Patent number: 4204831Abstract: A burner apparatus comprising in axial alignment a cylindrical first section connected through a restrictive opening to a frustoconical second section having its largest diameter at the downstream end and an axial outlet opening at the downstream end. Tangential combustion supporting gas inlets aligned in the same rotational direction are located in the cylindrical section and at the downstream end of the frustoconical section. The outlet opening in the frustoconical second section is of greater diameter than the restrictive opening between the sections and is of lesser diameter than the upstream end of the frustoconical second section so that a stable flame is produced in the second section, there is an inflow of external gas through the outlet opening, and a flow of combustion supporting gas in an upstream direction along the wall of the second section. A method for burning fuel in combustion supporting gas, particularly adapted to produce carbon black, is also provided.Type: GrantFiled: April 4, 1978Date of Patent: May 27, 1980Assignee: Phillips Petroleum CompanyInventor: John W.

Patent number: 4102967Abstract: Carbon black is pelleted by combining loose carbon black with an aqueous pelleting liquid and agitating the mixture. Additional loose carbon black is added in a series of increments, followed by additional aqueous pelleting liquid containing an additive such as ammonium lignin sulfonate. The process produces layered pellets having a hardened outer shell. In another embodiment, an oil is added following the incremental addition of the loose carbon black in order to produce pellets which have a dust-free surface.Type: GrantFiled: August 9, 1976Date of Patent: July 25, 1978Assignee: Phillips Petroleum CompanyInventors: John W.
