Filed:

Mar 30, 2012

Appl. No.:

13/436730

Inventors:

Andreas Herrig - Rheine, DE
Anurag Gupta - Houston TX, US

Assignee:

GENERAL ELECTRIC COMPANY - SCHENECTADY NY

International Classification:

F03D 1/06

US Classification:

416223 R

Abstract:

A wind turbine blade includes a root portion, a tip and a body extending between the root portion and the tip. The body has a pressure side and a suction side. The body further has at least one winglet. Each winglet has a spanwise extension towards the root portion of the rotor blade and that ends at the tip to form a winglet having a substantially C-shaped or substantially open P-shaped geometry.

Abstract:

A system and method for startup of a polyolefin reactor temperature control system having a first reactor temperature control path, a second reactor temperature control path, and a shared temperature control path. In some embodiments, during startup the second reactor temperature control path is configured to allow the temperature of a second reactor to rise due to the heat of the exothermic polymerization reaction occurring within reactor until reaching a predetermined setpoint temperature. In other embodiments, during startup a first reactor temperature control path is configured to include a heat exchanger used as a cooler, and a second reactor temperature control path is configured to include a heat exchanger used as a heater, to raise the temperature of the second reactor until reaching a predetermined setpoint temperature.

B01J 19/24
C08F 2/01

Abstract:

A manufacturing system for producing polyolefin includes a polymerization reactor, a flash chamber, and a purge column. In certain embodiments, the purge column may receive a solids stream directly from the flash chamber. Further, the purge column may function as a feed tank for an extruder within an extrusion/loadout system. According to certain embodiments, the manufacturing system may be configured to consume less than 445 kilowatt-hours of energy per metric ton of polyolefin produced based on consumption of electricity, steam, and fuel gas.
