Patent application number | Description | Published |
20090020296 | Method for extinguishing a fire in a silo - The invention relates to a method for extinguishing burning deposited goods situated in a silo, inert gas being introduced into the silo above the burning deposited goods and off gas being extracted above the burning deposited goods from the silo. | 01-22-2009 |
20100096146 | METHOD FOR PRODUCING CRUDE OIL - The invention describes a method for injecting a fluid into a crude oil-containing layer of rock or earth by means of a suitable line, wherein the line is introduced into the layer of rock or earth and the fluid is injected for the purpose of an enhanced crude oil production from the crude oil-containing layer of rock or earth. | 04-22-2010 |
20100101808 | METHOD FOR PRODUCING CRUDE OIL - The invention describes a method for injecting a fluid into a crude oil-containing layer of rock or earth by means of a suitable line, wherein the line is introduced into the layer of rock or earth and the fluid is injected for the purpose of an enhanced crude oil production from the crude oil-containing layer of rock or earth. | 04-29-2010 |
20100170683 | GAS ACTIVITY ANALYSIS IN THE GROUND - A method of introducing a propellant gas into the ground is described, wherein a trace gas that can be analysed above the ground or the earth's surface is added to said propellant gas. According to the invention hydrogen is used as the trace gas, whereby the proportion of the trace gas hydrogen in the propellant gas/trace gas mixture is a maximum of 10% by vol., preferably a maximum of 5% by vol. | 07-08-2010 |
20100186952 | METHOD FOR INJECTING A FLUID - A method and a device for injecting a fluid into a layer of rock or earth, such as a crude oil-containing layer of rock or earth, for example, for the tertiary crude oil production by means of a suitable line, wherein the line is introduced into the layer of rock or earth. The line consists of an inner pipe and an outer pipe. The inner pipe is provided with injection nozzles. The injection nozzles are positioned and thus ensure a pressing of the fluid into the surrounding layer of rock or earth via the openings in the outer pipe in a positioned manner. Means which allow for a selective impacting of the individual injection nozzles, are located in the interior of the inner pipe. The fluid is pressed into the surrounding layer of rock or earth in a positioned manner. | 07-29-2010 |
20100206556 | ENHANCING THE RECOVERY OF CRUDE OIL WELLS - Described is a method for introducing at least one manufactured gas in the area of an oil reservoir for the purpose of enhancing the recovery of the oil reservoir. The gas is at least temporarily introduced in shock waves. | 08-19-2010 |
20110024136 | METHOD FOR EXTINGUISHING A SMOULDERING FIRE IN A SILO - The invention relates to a method for extinguishing a smouldering fire in a silo by introducing inert gas into the silo. The inert gas is introduced through a venturi-type nozzle above the stored content in the silo with a slow streaming velocity in such a way that mass ratio of the entrained surrounding gas to the incoming liquid inert gas is between 0.5 and 20. Thus a closed inert gas layer is formed above the smouldering fire. | 02-03-2011 |
20130129589 | Process for the Removal of Hydrogen Sulfide from a Gas Stream - The application relates to a process for the removal of hydrogen sulfide from a gas stream by catalytic direct oxidation without employing the combustion step of a Claus process. The process is particularly suitable for desulfurization of gas streams that contain hydrogen and allows sulfur recovery efficiency of better than 99%. | 05-23-2013 |
