Patent number: 7828903Abstract: A method for removing pipe tuberculation includes the initial step of preparing an access point in the existing pipe by digging to the pipe and sawing a section from the pipe or creating an access port. The section of the pipeline to have its tuberculation removed is isolated by closing valves or creating another access point and sealing the end. Then, a reaming tool is introduced to the interior of the pipe. The reaming tool is attached to a hollow rod string capable of producing moderate thrust and pullback force, and must also produce sufficient torque when rotated.

Publication number: 20090114247Abstract: The annular surface between the tubing and casing of an oil or gas well as well as flow conduits and vessels may be contacted with a foamed treatment composition containing a gas, a foaming agent and a treatment agent. The treatment agent may be an inhibitor or removal agent for scales, corrosion, salts, paraffins or asphaltenes. The foam, upon destabilization, renders a thin film of concentrated treatment agent on the external surfaces of the tubing, inside the casing and in the perforations of the oil or gas well or on the flow conduits or vessels.Type: ApplicationFiled: January 9, 2009Publication date: May 7, 2009Inventors: James Michael Brown, John Gregory Darby

Patent number: 7513260Abstract: A coke removal system removes coke deposits from the walls of a high temperature passage in which hydrocarbon fuel is present. The system includes a carbon-steam gasification catalyst and a water source. The carbon-steam gasification catalyst is applied to the walls of the high temperature passage. The water reacts with the coke deposits on the walls of the high temperature passage to remove the coke deposits from the walls of the high temperature passage by carbon-steam gasification in the presence of the carbon-steam gasification catalyst.Type: GrantFiled: May 10, 2006Date of Patent: April 7, 2009Assignee: United Technologies CorporationInventor: He Huang

Patent number: 7507298Abstract: By constructing tank cleaning equipment according to the invention such that it comprises a cleaning jetting part (7, 9) as well as a suction part (4), the equipment can work with the same cleaning medium which is recirculated. This saves supply of fresh cleaning medium, and since used medium is thus not discharged, it is not necessary to establish deposit facilities to avoid pollution. Furthermore, this equipment according to the invention may advantageously be used for keeping so-called drilling mud in a mixed and thus ready-to-use state, even when left to stand for an extended period of time in a tank. The nozzle jets (10) thus keep the mud in the tank in a constantly mixed state, and the mud can therefore be sucked through the suction pipe (20) for pumping in the drill pipe, it being ensured that the mud is homogeneous and has a suitable viscosity.Type: GrantFiled: September 5, 2002Date of Patent: March 24, 2009Assignee: Alfa Laval Tank Equipment A/SInventors: Henrik Falster-Hansen, Ib René Vinther Elgaard
