Abstract: A method and apparatus for separating acid gas from a natural gas stream suitable for use on an offshore facility located on a platform or floating vessel are disclosed. The method includes the steps of: contacting the natural gas stream with a semi-lean amine solution in a static mixer to produce a rich amine solution, separating a first portion of carbon dioxide from the rich amine solution to produce the semi-lean amine solution, and heating a portion of the semi-lean amine solution to separate a second portion of carbon dioxide and produce the lean amine solution. The rich amine solution and semi-lean amine solution can be heated using recovered waste heat.

The method includes the steps of: contacting the natural gas stream with a semi-lean amine solution and a lean amine solution to produce a rich amine solution, separating a first portion of carbon dioxide from the rich amine solution to produce the semi-lean amine solution, and heating a portion of the semi-lean amine solution to separate a second portion of carbon dioxide and produce the lean amine solution. The rich amine solution and semi-lean amine solution are heated from using recovered waste heat derived from one or more of a land based facility or an off-shore facility located on a platform or floating vessel.

Abstract: A system and a method for transferring cryogenic fluids (LNG) between a first LNG storage tank and a second LNG storage tank wherein the transfer system includes a means for cooling the transfer lines when the system is not in use. The system has two transfer lines which extend between the tanks and which are fluidly connected together to form a closed loop when the system is not in use. LNG is circulated at high pressure through the closed loop during idle intervals to keep the lines at a temperature at which LNG will remain in a single phase, i.e. liquid.

Abstract: A method for reducing signal degradation in a foam covered hydrophone used in seismic marine streamers. Said method comprises purging the foam streamer body with a fluid which is at least partially miscible with an oil used to fill said foam body. Thereafter, said foam body is filled with oil by gravity-assistance. Said method substantially removes air trapped in said foam body thereby reducing said signal degradation. Fluids, which can be utilized include butane, carbon dioxide, and fluorocarbons.

Abstract: Oil is recovered from a subterranean oil-containing formation by fracturing the formation around the injection well and thereafter injecting a CO.sub.2 foam or a mixture of steam and a CO.sub.2 foam into the injection well to displace mobilized oil toward a production well for recovery.
