20090189301 | DOWNCOMER DISTRIBUTOR - A tray assembly is provided for improved gas/liquid contact when used in a large chemical process tower. Each tray has a downcomer wall of which the lower portion is a distributor. The distributor has discharge ports sized to control the rate of liquid flow at different positions across the distributor and flanges aligned individually to direct liquid flow from different discharge ports across different areas of the tray deck immediately below the downcomer. In combination, discharge ports and liquid flow directing flanges effect even liquid flow across the surface of the tray immediately below. Benefits of this invention are trays with better mass transfer efficiency and enhanced capacity compared with prior art trays. | 07-30-2009 |

The apparatus of the present invention has capability of improving processing throughput by 50% when compared with prior art apparatus, with greater de-entrainment efficiency (achieving 99.7% removal of droplets larger than 10 microns in size). | 09-01-2011 |
20120118154 | Process and apparatus for removal of oxygen from seawater - A process and apparatus is provided for reduction of dissolved oxygen content in seawater from about 8 ppm in the feed seawater to about 10 ppb or less. Significant advantages are achieved by: use of a separator in horizontal alignment to provide high gas-liquid contacting area for separation and de-entrainment within the separator, thereby providing higher throughput; and heating seawater to at least 30° C. and up to 60° C., so as to enhance removal of oxygen from seawater; use of once-through fuel gas as stripping gas and its subsequent combustion for heating the seawater provides for high efficiency and reduction of fouling. The combination of these features allows the amount of residual oxygen in deoxygenated seawater to be reduced to below 10 ppb and as low as 2 ppb. | 05-17-2012 |
20130116489 | Separating styrene from C6 - C8 aromatic hydrocarbons - The invention disclosed relates to a process for refining a hydrocarbon feed to make substantially styrene-free C6-C8 aromatic hydrocarbons (BTX). The hydrocarbon feed, for example, unhydrotreated pyrolysis gasoline, is distilled to make a BTX rich stream containing styrene which is fractionated to separate C6 and C7 hydrocarbons from C8 hydrocarbons including styrene. Styrene in the C8 hydrocarbons reacts in the presence of a selective etherification catalyst with a C1-C3 lower alkyl alcohol to form the corresponding styrene ether, which is then separated by distillation into a styrene ether stream and a C8 hydrocarbons rich stream. The C8 hydrocarbons rich stream is then re-mixed with the C6 and C7 hydrocarbons, and sent to hydrogenation reactors to remove sulphur and olefinic hydrocarbons to form substantially styrene-free BTX. | 05-09-2013 |

20090269753 | GENOTYPING FOR SRC-1 PREDICTS FOR BONE LOSS - Osteoporosis is a common skeletal disease characterized by loss of bone mineral density (BMD) and increased risk of fracture. Osteoporosis most commonly occurs in postmenopausal women due to estrogen deficiency. We identified 3 genetic variants in steroid receptor coactivator 1 (SRC-1) that are significantly associated with a decrease in BMD in women. We characterized a functional variant in exon 18 of SRC-1 that is associated with increased loss of bone mineral density in women who received tamoxifen for treatment or prevention of breast cancer. In vitro experiments show that this variant decreases estrogen receptor alpha response (ER-alpha) to hormone, suggesting an attenuated response to endogenous and exogenous hormones in the bone of these women, and therefore a need for additional bone protective measures. | 10-29-2009 |

20120181220 | Feed Mixtures for Extraction Process to Produce Rubber Processing Oil - Deasphalted residual oil (DAO) and the aromatics-rich extract that is derived from DAO have low polycyclic aromatics contents, relatively low aniline points, and high flash points. They form blending stocks that improve properties of mixed feedstocks to consistently produce environmentally qualified rubber processing oil (RPO) by extraction under low solvent-to-oil ratios and moderate extraction temperatures. Distilling a petroleum crude oil under atmospheric pressure generates a bottom residual oil which is then subject to vacuum distillation to yield a bottom residual oil. DAO is produced by removing the asphalt from the vacuum bottom residual oil through extraction with light paraffinic solvent. The extract of DAO is a co-product in the production of the bright stock of the lubricating oil through extraction. The feedstock is mixed with the extract from a petroleum fraction boiling in lube oil range. Liquid-liquid counter-current extraction yields a raffinate stream; removal of solvent therefrom produces the RPO. | 07-19-2012 |

20110086464 | TUNING OF FE CATALYSTS FOR GROWTH OF SPIN-CAPABLE CARBON NANOTUBES - Growing spin-capable multi-walled carbon nanotube (MWCNT) forests in a repeatable fashion will become possible through understanding the critical factors affecting the forest growth. Here we show that the spinning capability depends on the alignment of adjacent MWCNTs in the forest which in turn results from the synergistic combination of a high areal density of MWCNTs and short distance between the MWCNTs. This can be realized by starting with both the proper Fe nanoparticle size and density which strongly depend on the sheet resistance of the catalyst film. Simple measurement of the sheet resistance can allow one to reliably predict the growth of spin-capable forests. The properties of pulled MWCNTs sheets reflect that there is a relationship between their electrical resistance and optical transmittance. Overlaying either 3, 5, or 10 sheets pulled out from a single forest produces much more repeatable characteristics. | 04-14-2011 |

20120176930 | SYSTEM AND METHOD FOR PROVIDING CO-SIGNALED RETURN LABEL SWITCH PATHS - An approach is provided for establishing label switch paths associated with a new routing node of a label switch network. A new routing node is determined to be activated within a label switch network. Label pair generation logic is employed to generate a path set-up message to establish a pair of label switch paths between the new routing node and an activated routing node of the label switch network. Another path set-up message is repeatedly generated for each of a plurality of activated routing nodes within the label switch network to establish pairs of label switch paths. | 07-12-2012 |
