摘要： A high voltage direct current (HVDC) power transmission system includes a cable fault ride-through system. The cable fault ride-through system is configured to ensure the HVDC power transmission system remains operational via an earth path between the power source end and the load end during a transmission cable fault, even in the absence of a neutral bus and/or dc circuit breakers.

摘要： The present invention relates to a gate valve (10), in particular for returned drilling mud pressure control and/or well killing. The gate valve comprises: a flow passage (14); and a gate member (22) movable for intersecting the flow passage. The gate member includes a gate port (28) which extends from one face (34a) to an opposite face (34b) of the gate member and is alignable with the flow passage for allowing material in the flow passage to pass through the gate member, and a groove or recess (30) is provided in an inner wall (32) of the gate port, the groove or recess extending from the one face to the opposite face of the gate member. The present invention further relates to a method for returned drilling mud pressure control and/or well killing, and uses of a gate valve.

摘要： A process for absorption and desorption of CO2 from an flue gas comprising feeding the flue gas into a mainly horizontal channel (20, 22, 249 where an absorption fluid is spray in to the channel in the flow direction of the flue gas and collected as CO2 rich absorption fluid at a lower part of the channel and transported into the centre of a rotating desorber wheel (30), where the CO2 is desorbed and the lean absorption fluid is returned to the channel is disclosed. This process can be utilized with absorption fluids with high concentration of conventional amine CO2 absorbents. Disclosed is also the use of an amine absorbent in a concentration of between 61 and 100% by weight for the absorption of CO2 from a gas stream, where the amine is an alkanol amine.

摘要： A method of controlling the annular pressure in a well during a well construction operation. The operation comprises pumping a fluid down a tubing located within the well and extracting the fluid that flows back through an annulus within said well and surrounding the tubing. The method comprises defining a set pressure pref, determining a desired extraction flow rate qc of fluid from said annulus in dependence upon the set pressure pref and a pumped flow rate into the annulus, and configuring an extraction path to achieve said desired extraction flow rate.

摘要： A method of processing controlled source electromagnetic (CSEM) data is provided for reducing the airwave contribution. CSEM data are acquired, for example using a conventional towed source (4) and receiver (5) arrangement. The recorded data are weighted in accordance with the geometrical spreading of the airwave component. The differences between pairs of weighted data records are then formed.

The desorber 200 is connected to the absorber 100 to receive C02 rich absorption liquid 3, and the desorber 200 is rotatable and comprises a desorption chamber 202 provided with a rotatable heat exchanger and means for rotating the desorber, such that the absorption liquid droplets are moved by aid of centrifugal force through the heat exchanger whereby the absorption liquid droplets are heated and C02 is desorbed and separated from the absorption liquid droplets, and lean absorption liquid 2 is circulated to the absorber. The present invention also relates to a process for accelerated absorption and desorption of C02.
