Title: Removing carbon di:oxide from gas streams - by absorption in conc. aq. hindered mono:amine solns.; allowing rapid desorption on regeneration
IPC: B01D53/14
Filed: 1978-01-05
Abstract: The gas stream is contacted with a conc. aq. soln. of a water-sol. prim. monoamine, (I) with a sec. C-atom bound to the amino group), at 20-100 degrees C and a partial pressure of CO2 of 0.07-70 atmos. to absorb the CO2-contg. acid gases. The absorption sol. is subsequently regenerated by heating at 50-170 degrees C and 0.07-3.5 atmos to desorb the CO2. The process is useful for removing CO2-contg. acid gases such as CO2, H2S, SO2, CS2, COS and O- adn S-derivs. of 1-4C hydrocarbons from gas streams using conc. aq. solns. of amines such as 2-amino-1-propanol, 2-amino-1-butanol, 2-amino-3-methyl-1-butanol, 2-amino-1-pentanol, 2-amino-1-hexanol and 2-aminocyclohexanol. The amine solns. give good absorption of the CO2-contg. gases, and desorption is more rapid and more complete than when using prior art amine solns. such as monoethanolamine soln.

Title: Rig for feeding conductor pipe in offshore oil and gas wells - includes rotating column tower, displaceable rotary table and separate winches, hoists and elevators
IPC: E21B3/04
Filed: 1978-01-19
Abstract: The conductor pipe for an oil or gas offshore well is brought into the ground by means of a drilling rig comprising a conventionals kidded base to which an eccentrically mounted column is attached. The column is equipped with a rigid base and a rotating column to which a crown block and winch are attached. At the top of the column there is an independently rotating load arm to which an auxiliary hoist is attached. The column also has vertical guide rails to which an elevator hoist is attached. This hoist can be brought into a position vertically above the well or into an inoperative position by a rotation of the column as can the winch and crown block. The rotary table is mounted on a side so that it can be displaced out of the operating position. The pipe clamp immediately below the rotary table is also mountedon sides. Between the rotary table and the lower pipe clamp, there is an additional pipe clamp mounted on vertical slides which enables conductor pipe or drill pipe tube moved vertically without using the column hoists. By using separate hoisting and manipulating equipment for the conductor pipe, the switch from drilling to placing of conductor pipe and vice versa can be made quickly and, by the use of lifting clamps beneath the rotary table, a lighter tower can be used capable of greater flexibility in its range of operations.

Title: Injection moulding e.g. plastic pipe with socket end - and final shaping outside mould to secure e.g. lip seal ring before pipe fully cooled
IPC: B29C57/02
Filed: 1982-07-27
Abstract: The arrangement is intended for manufacturing plastic pipe fittings or the like by injection-moulding in a mould (of which 3 are the removable inner parts) and removing each fitting from the mould before it is fully cooled to complete cooling away from the mould until fully set. Whilst outside the mould and before fully cooled, the fitting is subjected to a final shaping operation and only then fully cooled and allowed to set before final discharge. This shaping operation may be combined with the application of one or more previously manufactured components, e.g. lip seal rings, or such components may be formed (injection-moulded) in situ during that operation. Used for manufacture of e.g. plastic pipe fittings by injection-moulding followed by final shaping outside the mould before fully set. The arrangement makes it possible to manufacture a complete product incorporating the sealing rings or the like in the time of one moulding cycle, thus avoiding intermediate storage, re-heating, assembling the rings and final shaping to secure them, and the handling this involves.
