20110117926 | Network-based positioning mechanism and reference signal design in OFDMA systems - A network-based positioning mechanism is proposed. A serving BS first allocates radio resource to a target UE for network-based positioning in a wireless communication system. The target UE then transmits a positioning reference signal (PRS) to the serving BS and a plurality of cooperative BSs at the same time instant. All the cooperative BSs then conduct PRS detection and TOA measurements. Finally, the serving BS conducts positioning estimation based on the TOA measurement results. In one novel aspect, only one PRS transmission is required in one positioning opportunity for one positioning result. Candidates of PRS are selected with respect to different scenarios and allocated in a PRS resource region. Multiple positioning opportunities and multiple reference signals may be multiplexed over time, frequency or code domain in the PRS resource region. In one embodiment, the PRS is configured in such a way that both radio resource consumption and interference is minimized. | 05-19-2011 |

20090014313 | Low-energy extractive distillation process for dehydration of aqueous ethanol - An energy-efficient extractive distillation process for producing anhydrous ethanol from aqueous/ethanol feeds containing any range of ethanol employs an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be incorporated into an integrated process for producing anhydrous ethanol used for gasoline blending from fermentation broth. By using a high-boiling extractive distillation solvent, no solvent is entrained by the vapor phase to the EDC overhead stream, even under no liquid reflux conditions. The energy requirement and severity of the EDC can be further improved by limiting ethanol recovery in the EDC. In this partial ethanol recovery design, ethanol which remains in the aqueous stream from the EDC is recovered in a post-distillation column or the aqueous stream is recycled to a front-end pre-distillation column where the ethanol is readily recovered since the VLE curve for ethanol/water is extremely favorable for distillation. | 01-15-2009 |

The improved process can effectively remove and recover the heavy hydrocarbons and/or remove polymer contaminants from the solvent in a closed solvent circulating loop through mild operating conditions with no additional process energy being expended. With the improved process, the overhead reflux of the EDC may be eliminated to further reduce energy consumption and to enhance the loading and performance within the upper portion of the EDC, especially when two liquid phases exists therein. | 04-23-2009 |

The revamp entails essentially only piping changes and minor equipment adjustments of the original liquid-liquid extraction facility, and is therefore, reversible. | 10-15-2009 |

It has been demonstrated that the light non-aromatic hydrocarbons in the raffinate stream generated from the extractive distillation or the liquid-liquid extractive process for aromatic hydrocarbons recovery can displace not only the heavy non-aromatic hydrocarbons but also the heavy aromatic hydrocarbons from the extractive solvent, especially when the aromatic hydrocarbons in the solvent are in the C | 02-16-2012 |
