20100189208System and method for clock jitter compensation in direct RF receiver architectures - Systems and methods that provide clock jitter compensation architectures that improve the performance of direct radio frequency (RF) receivers by injecting a calibration tone into the received radio frequency (RF) signals in order to help identify and then compensate for the clock jitter noise. After injecting the tone, the jitter noise going through the direct RF bandpass sampling receiver is estimated using a narrow bandwidth filter, and the received signals are further processed and demodulated depending on the Nyquist zone of the received signal. The relative modulation factor for the modulation is computed and then applied to the Nyquist zone to de jitter that particular Nyquist zone.07-29-2010

20100018248Controlled Freeze Zone Tower - A cryogenic distillation tower is provided for the separation of a fluid stream containing at least methane and carbon dioxide. The cryogenic distillation tower has a lower stripping section, an upper rectification section, and an intermediate spray section. The intermediate spray section includes a plurality of spray nozzles that inject a liquid freeze zone stream. The nozzles are configured such that substantial liquid coverage is provided across the inner diameter of the intermediate spray section. The liquid freeze zone stream generally includes methane at a temperature and pressure whereby both solid carbon dioxide particles and a methane-enriched vapor stream are formed. The tower may further include one or more baffles below the nozzles to create frictional resistance to the gravitational flow of the liquid freeze zone stream. This aids in the breakout and recovery of methane gas. Additional internal components are provided to improve heat transfer and to facilitate the breakout of methane gas. 01-28-2010

20100305301Method And Apparatus For Elastomer Finishing - In the production of elastomers the product obtained from the polymerization process is often in the form of a slurry. Described herein are an apparatus and a process for “finishing” the elastomer, i.e., dewatering and drying the elastomer. The process comprises the steps of obtaining a slurry comprising water and elastomer; passing the slurry through a first dewatering device to produce a wet elastomer crumb, wherein the first dewatering device comprises two dewatering extruders in parallel; passing the wet elastomer crumb through a second dewatering device; and then passing the wet elastomer crumb through a drying device to produce a dried elastomer crumb.12-02-2010

20100273936Finishing Process for Amorphous Polymers - Extruded, copolymer pellet compositions and methods for making the same. A copolymer pellet composition can have an ethylene content of about 40 wt % to about 50 wt % and a propylene content of about 50 wt % to about 60 wt %, based on total weight of the copolymer, wherein the copolymer has a MFR (230° C./2.16 kg) of from about 3.0 g/10 min and about 25 g/10 min; a MWD (Mw/Mn) of about 2.3 or less; and no measurable melting peak, as measured by DSC.10-28-2010
20110172375Processes And Apparatus For Continuous Solution Polymerization - Described herein in one embodiment is a plant for the continuous solution polymerization of one or more monomers in a solvent, e.g., a hydrocarbon solvent. In one aspect, the plant comprises a high pressure pump and at least one heat exchanger downstream of the pump. In another aspect a feed is cooled by three heat exchangers which are refrigerated by means of a common three stage compressor. In another aspect, the plant comprises a primary reactor and a secondary reactor arranged to operate in parallel, in which the ratio of volume of the primary reactor to the secondary reactor is in the range of 60:40 to 95:5. In another aspect, a method of defouling a heat exchanger is provided in which the level of liquid refrigerant in the heat exchanger is temporarily lowered.07-14-2011
20110172382Processes And Apparatus For Polymer Finishing And Packaging - Provided are apparatus and methods relating to the finishing line of a continuous solution polymerization plant. In one aspect, an apparatus includes a pelletizer having cooling liquid, e.g., water or aqueous solution, into which is added a pelletization aid. In another aspect, the apparatus comprises means to remove residual polymer particles from the pelletizer cooling liquid. In a further aspect, the apparatus comprises conduits of at least 50 m in length for carrying propellant cooling liquid from the pelletizer to a drying apparatus. The residence time of the pellets in the cooling liquid may be 10 seconds or more. In a further aspect, a drying apparatus is provided for the pellets which comprises first and second drying zones. In a further aspect, a pneumatic conveyor is provided for carrying pellets to a packaging apparatus. In a further aspect, a packaging apparatus is provided comprising a blender silo.07-14-2011
20110172383Vacuum Devolatilizer - Provided is a vacuum devolatilizer for use in a polymer manufacturing or processing plant. The devolatilizer comprises a vacuum chamber having an inlet for a polymer melt, an outlet for a polymer melt, a vacuum port through which volatiles may be removed and a stirrer shaft port for the entry of a stirrer shaft. The stirrer shaft passes through the at least one stirrer shaft port and extends into the vacuum chamber and carries an agitation means. The stirrer shaft seal is associated with each stirrer shaft port for sealing against the stirrer shaft and each stirrer shaft seal has an external portion outside the vacuum chamber. The devolatilizer is provided with a motor located outside of the vacuum chamber for rotating shaft and comprises means for blanketing the external portion of the stirrer shaft seal with a low oxygen content gas or vapor, e.g., nitrogen, helium, steam, or carbon dioxide.07-14-2011
