    • A tubular anchoring system includes a frustoconical member having a first frustoconical portion and a second frustoconical portion. The first frustoconical portion is tapered in a direction opposing a direction of taper of the second frustoconical portion and slips in operable communication with the first frustoconical portion are radially expandable in response to longitudinal movement of the first frustoconical portion relative to the slips. A seal in operable communication with the second frustoconical portion is radially expandable in response to longitudinal movement of the second frustoconical portion relative to the seal, and a seat having a surface configured to be sealingly engagable with a plug runnable thereagainst.

    • A process (10) for enhancing the energy output of an ethanol production facility has the steps of producing ethanol and stillage from a feedstock, anaerobically digesting said stillage so as to produce carbon dioxide and methane, compressing the methane, compressing the carbon dioxide, and, passing the compressed carbon dioxide to an oil-bearing formation. The compressed carbon dioxide (48) is injected under pressure into the oil-bearing formation (72) so as to produce live crude and natural gas. The compressed methane is delivered to a combustion turbine (46) so as to produce power and an exhaust. The exhaust of the combustion turbine is passed to a steam turbine (66) so as to produce steam and power (68).
    • 一种用于增强乙醇生产设备的能量输出的方法(10)具有以下步骤:从原料生产乙醇和丁醇,对所述釜渣进行厌氧消化以产生二氧化碳和甲烷,压缩甲烷,压缩二氧化碳,以及 ,将压缩的二氧化碳通入含油地层。 将压缩的二氧化碳(48)在压力下注入含油地层(72),以生产活的原油和天然气。 压缩的甲烷被输送到燃气轮机(46)以产生动力和排气。 燃气轮机的排气通过蒸汽轮机(66)以产生蒸汽和动力(68)。
