Characterization of hollow fiber membranes in a permeator using binary gas mixtures

We have studied the CO₂/CH₄ mixed gas permeation through hollow fiber membranes in a permeator. An approach to characterize the true separation performance of hollow fiber membranes for binary gas mixtures was provided based on experiments and simulations. Experiments were carried out to measure the retentate and permeate flow rates and compositions at each outlet. The influences of pressure drop within the hollow fibers, non-ideal gas behavior in the mixture and concentration polarization were taken into consideration in the mathematics model. The calculation results indicate that the net influence of the non-ideal gas behavior, competitive sorption and plasticization yields the calculated CO₂ permeance in a mixed gas permeator close to that obtained in pure gas tests. Whereas the CH₄ permeance is higher in the mixed gas tests than that in the pure gas tests, as the plasticization caused by CO₂ dominates the permeation process. As a result, the CO₂/CH₄ mixed gas selectivity is smaller than those obtained in pure gas tests at equivalent pressures.The calculated membrane performance shows little changes with stage cut if the effect of concentration polarization is accounted for in the calculation. The integration method developed in this study could provide more accurate characterizations of mixed gas permeance of hollow membranes than other estimation methods, as our model considers the roles of non-ideal gas behavior and concentration polarization properly.

Political orientation and modern versus aversive racism: Tests of Dovidio and Gaertner's (1998) integrated model.

According to J. F. Dovidio and S. L. Gaertner's (1998) integrated model of racism, politically liberal European Americans tend to express racism differently than conservative European Americans, with liberals demonstrating aversive racism and conservatives, symbolic or modern racism. In support of the model, in Experiment 1 liberals showed bias in favor of a twice-prosecuted African American relative to a European American in their judgment of double jeopardy, whereas conservatives did the reverse. Experiment 2 replicated these effects while eliminating a confound in the design of Experiment 1. Experiment 3 found evidence for the intrapsychic conflict hypothesized to underlie aversive racism. Specifically, only liberals displayed greater physiological arousal to the touch of an African American versus a European American experimenter.

VSP旅行时反演应用于VSP—CDP转换

非零偏移距垂直地震剖面(VSP)模型的制作是非零偏移距VSP资料处理的关键环节之一,是VSP-CDP转换的基础。本文试用旅行时反演修正非零偏移距VSP的模型,以加速模型的制作过程,提高非零偏移距VSP的处理速度。用合成VSP资料试算表明:旅行时的随机误差对模型的制作影响不大;只要能较准确地确定界面位置,用旅行时反演修改制作非零偏移VSP模型是可行的。本文还探讨了初始模型的不同选择方法,并将旅行时反演用于实际VSP资料的处理。结果表明,大大地节省了非零偏移距VSP资料的处理时间。

黄骅坳陷白水头-唐家河地区东营组地层地震模拟及响应曲线分析

根据对黄骅坳陷白水头—唐家河地区东营组钻井资料的统计分析，设计了3种不同地质模型．用于分析不同厚度、不同孔隙度和不同流体性质的储层所表现出的地层速度和密度特性，进而通过地震正演模拟研究，得到不同储层参数状况下的响应曲线。分析响应曲线发现，在该地区，当含水砂岩厚度为20m时．其地震反射振幅最大；而含油帮岩在厚度为18m时达到最大。当孔隙度达到22％时．含油砂岩的地震反射振幅会发生极性反转；而含水砂岩在孔隙度为28％时极性反转。这就为该地区的地震储层预测提供了依据。
