International Classification:

C07C007/04
C07C001/207

US Classification:

585809, 585638, 585820, 585639

Abstract:

This invention is directed to a method of removing dimethyl ether from an olefin stream. The method includes distilling the olefin stream so that the dimethyl ether is separated out of the olefin stream with propane. The olefin stream can then be further distilled to provide a polymer grade ethylene stream and a polymer grade propylene stream, with each stream containing not greater than about 10 wppm dimethyl ether.

US Classification:

166373, 166319, 166320, 166192, 166179

Abstract:

A completion system including a barrier valve operatively arranged in a tubing string to selectively impede fluid flow through a lower completion. At least one control line is included for supplying a control line pressure for controlling operation of the barrier valve. The at least one control line is operatively arranged with the tubing string for enabling tubing pressure in the tubing string to determine the control line pressure. A method of operating a barrier valve is also included.

US Classification:

166285, 166179, 166192, 166 51

Abstract:

A completion system, including a lower completion installed in a borehole proximate to a downhole formation. An intermediate completion assembly is included directly engaged with the lower completion. The intermediate completion assembly includes a barrier valve and packer device. The barrier valve is operatively arranged to selectively impede fluid flow through the lower completion and the packer device operatively arranged for isolating the formation. An upper completion string is included that is selectably engagable with the intermediate completion assembly. The barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitions to a closed position via the upper completion string when the upper completion string is pulled out of the borehole. A method of completing a borehole is also included.

US Classification:

166369, 166179, 166106, 166373

Abstract:

A retrofit assembly for functionally replacing a fluid isolation valve disposed in a borehole above a lower completion, including a barrier valve operatively arranged to selectively isolate the lower completion when the fluid isolation valve is open. The barrier valve is transitionable between an open position and a closed position due to engagement with an upper completion string. A packer device is included and operatively arranged to isolate a formation in which the borehole is formed. A method of retrofitting a completion system is also included.

US Classification:

166373, 166192, 166106, 166376

Abstract:

A completion system, including a lower completion initially fluidly open. A production string is included having a removable plug configured to impede fluid flow through the production string. The removable plug is run in with the production string. An intermediate completion assembly is included that couples the lower completion to the production string. The intermediate completion assembly has a packer device and a barrier valve. The packer device is operatively arranged to be set by pressurizing fluid in the production string against the removable plug. The barrier valve is operatively arranged for selectively impeding fluid flow between the production string and the lower completion after the removable plug is removed. A method of completing a borehole is also included.

International Classification:

F02C 700
F02C 916

US Classification:

60 3905

Abstract:

A process for maintaining or increasing the power output of a gas turbine is described in which the ambient temperature in the locus of the gas turbine is monitored. In response to an increase in ambient temperature above the design temperature of the turbine the air volumetric flow rate through the compressor is increased and water is added to the combustion chamber in an amount sufficient to increase the volumetric flow rate of the gases through the expander section to the volumetric flow rate limit of the section.
