Abstract:
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.

Abstract:
For the treatment of a wastewater containing sour gases with a stripping gas, resultant stripping gas containing the sour gases is introduced into at least one combustion stage within the total process for recovery of the sulfur-containing components, the wastewater being stripped with at least a portion of the amount of O.sub.2 -containing gas required in the subsequent combustion stages.
Abstract:
For the removal of sulfur compounds, especially H.sub.2 S, from gases that contain hydrocarbons, and/or CO.sub.2, the gases are scrubbed with a physical solvent, which is to be regenerated and reused. To obtain sulfur free of hydrocarbons, as well as a practically sulfur-free LPG fraction and optionally a C.sub.5+ fraction, an oxidizing agent is added to the solvent for reacting the sulfur compounds to elemental sulfur, and the sulfur is separated. The concomitantly absorbed hydrocarbons and/or CO.sub.2 can then be desorbed from the separated solvent by physical regeneration and can be recovered.
Abstract:
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.
Abstract:
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.
Abstract:
The invention relates to a burner with a burner head (1) and a gas feed pipe (2) that is located in the burner head (1) and that is surrounded by an ring channel (3) for feed of another gas. In the gas feed pipe (2) and in the ring channel (3), there are means (10, 11) for producing a swirl of the gas flowing through the gas feed pipe (2) and that flowing through the ring channel (3).
Abstract:
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.
Abstract:
The invention relates to a reactor for carrying out reactions having a high enthalpy change containing catalyst particles between cooled dividing walls. According to the invention, the cooled dividing walls are formed by metal plates/metallic components in which hollow or intermediate spaces in the form of channels are provided in the metal plates/components for accommodating and conveying a cooling medium so as to cool the reactor. The reactor can be used for carrying out strongly exothermic catalytic reactions, for example for the selective hydrogenation of acetylene to ethylene.
Abstract:
The invention relates to a process for the production of ethylene oxide from a gaseous feedstock—in a cooled exothermic catalytic reaction of ethylene and oxygen from this feed gas in parallel flow-through reaction zones. According to the invention, the reaction zones are limited by cooled dividing walls, and the cooling is achieved by a fluid that flows inside the dividing walls. In addition, the invention relates to a reactor for this purpose with catalyst particles between cooled dividing walls. According to the invention, the cooled dividing walls are formed with the aid of metal plates, and cavities in the form of channels for receiving and for passing through a coolant are arranged for cooling in the metal plates.
