Title: Multiple-set packer and method
Inventor: STOKLEY CHARLES O
IPC: E21B33/127
Filed: 1989-06-07
Granted: 1992-12-01
Abstract: .     Abstract of the Disclosure A packer assembly is provide suitable for multiple setting and unsetting operations in a well bore during a single trip to seal the annulus between the interior walls of the well bore and a tubing string.  The packer Is set by dropping a metal ball which plugs the passageway through the tubing string, such that tubing pressure may thereafter be increased  to  inflate  the  packer.   A  sleeve is axially movable within a control sub from a ball stop position to a ball release position, and has a cylindrical-shaped interior surface  with a diameter only  slightly  greater  than the ball.   Collet fingers carried on the sleeve are radially movable from an inward position to an outward position to atop or release the ball as a function of the axial position or the sleeve.  Fluid flow through the tubing string is thus effectively blocked when the sleeve  is  in the ball stop position because of the close tolerance between the sleeve and the ball, while the ball is freely released from the sleeve and through the packer assembly when the sleeve is moved to the ball release position.

Abstract: The invention relates to a method and plant for providing heat recovery from hot and moist gas by water vapor absorption. The hot and moist gas, e.g. a flue gas is led in through a flue gas duct (1) to a chamber where the flue gas is washed in a filter (3) sprayed with water, whereby the gas is also cooled so that the heat from cooling is used for vaporizing a part of the water. In this state the gas is brought into contact with a hygroscopic solution (17) through an absorption zone (16) in an absorption tower (15). After treatment, the gas is taken through a flue gas outlet (18), the hygroscopic solution which was supplied with water vapor being taken to a section for vaporization by means of a vaporizer (26) to which heat (27) is supplied. The latent heat coming from the vaporization is converted in the heat exchanger (33) so that it may be utilized. The concentrated part of the hygroscopic solution is merged with the non-concentrated part and taken (21) to a further heat exchanger (23) for recovering (35) heat for utilization, and subsequently refluxed back into contact with flue gas in the absorption tower (15).
