Abstract:
The invention relates to a method for increasing the energy and cost effectiveness of a gas power plant or thermal power plant, and for energy and cost effective CO 2 capturing from flue gas with CO 2 enriched content. The plant comprises preferably two gas turbines comprising at least a compressor (13) and a turbine (14) and further comprising a combustor (10), the flue gas from the combustor (10) being expanded, cooled down and passed through a cleaning unit (11) where at least major parts of the CO 2 content is removed from the flue gas. Re-circulated flue gas is further used for cooling down the flame tube (40) in the combustor (10), and enriching the CO 2 content of the flue gas, the fresh air supplied to the combustor (10) providing a nearly stoichiometric combustion. The invention relates to an improved combustor system resulting in increased energy efficiency and increased output maintained at a highest possible level. The invention also relates to a power plant using the method.

Abstract:
Coupling device (1) for connection and disconnection of a bottomhole equipment, comprising; a male part arranged at the end of a coiled tubing, having a conically shaped stinger (3) with locking grooves (4); a female part (5) comprising a receptacle (7) in an upper end adapted to receive the stinger of the female part (6) and a house (8) that constitutes the outer part of the female part from the receptacle to a lower end (9), distinguished in that the female part comprises: a hold open sleeve (10) within the house, which is axially displaceable in the house in the direction towards the lower end and has an internal diameter smaller than the receptacle; locking dogs (11) arranged between the house and the hold open sleeve with a biasing device (12) pushing the locking dogs radially inwards; a locking device arranged axially displaceable in the house below the locking dogs, having a biasing device (14) pushing the locking sleeve towards the upper end and a internal diameter smaller or equal to the locking dogs in extended position; a verifying bolt (15) with a biasing device (16) pushing the verifying bolt radially inwards, which verifying bolt before joining the male and female parts has an outer end extending out of the house. When joining the male and female parts the coupling device will lock automatically, as the hold open sleeve (10) is pushed into the locking sleeve (13) by the stinger, after which the locking dogs (11) are pushed into the grooves (4) of the stinger, after which the locking sleeve is pushed up over the locking dogs locking said locking dogs, after which the verifying bolt will be pushed into an adapted opening (17) in the locking sleeve, thereby verifying correct locking.
Abstract:
Vibration reducer that reduces or removes flow-induced vibrations in a pipe, in particular a coiled tubing, distinguished in that the vibration reducer comprises at least one continuous band arranged as a spiral spring that elastically can be extended to surround a substantial part of the length of the pipe exposed to vibration inducing water flows. Method with use of the vibration reducer.
Abstract:
The present invention provides a method of inhibiting formation of solid hydrates in a conduit (10) used to contain a flowing, water-containing hydrocarbon, which method comprises introducing into said hydrocarbon in said conduit a gas (4, 5, 6) which raises the pressure threshold for hydrate formation for said water-containing hydrocarbon, said gas being introduced in a manner which causes it to travel along at least part of said conduit in the direction of hydrocarbon flow.
Abstract:
A method is provided for use in a telecommunications network in which an Sh interface is used for communications between a database client (22) and a database server (20) of the network. The database server has access to at least one database for storing user data such as repository data and user profile data associated with different users of the network. The Sh interface is used to convey at least one of the following types of extended data management information between the database client (22) and the database server (20): first information enabling the database client (22) to use the database server to perform a database operation on a part or parts of the user data; second information enabling the database server (20) to provide a partial response to a request for user data from the database client (22); third information enabling the database server (20) to control the flow of requests from the database client (22); and fourth information enabling the database server (20) to choose the type of database used to store user data it receives from the database client (22).
