A series solution technique is developed to express each product composition and the pressure ratio as a power series in terms of a dimensionless membrane area for shell side constant-pressure feed flow. Cocurrent or countercurrent rating or design problems require the solution of elther one algebraic equation, two coupled algebraic equations, or three coupled algebraic equations to determine the unknown quantities of interest. Calculated product and reject compositions, stage cuts, and closed-end pressure ratios compare quite well with those from numerical solutions for practically useful low to moderate cuts over a wide range of parameters. Cocurrent rating calculations requiring solution of only one algebraic equation are recommended for shortcut procedures since flow pattern effects are significant but not large.","PeriodicalId":13548,"journal":{"name":"Industrial & Engineering Chemistry Fundamentals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1986-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90076264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nagashima","doi":"10.1021/I100021A017","DOIUrl":"https://doi.org/10.1021/I100021A017","url":null,"abstract":"By means of a modified corresponding states principle developed by the present authors for the vapor pressures of H/sub 2/O isotopes, a few experimental data for the vapor pressure of tritium oxide (T/sub 2/O), available at lower temperatures, have been extrapolated to the critical temperature. By the use of the extrapolated saturation curve and an empirical relationship between the critical pressure P /sub C/ and the critical temperature T /sub C/, the location of the critical point of T/sub 2/O on the P-T plane has been estimated. The critical density p/sub C/ has also been estimated on the assumption that the critical molar densities are identical among the H/sub 2/O isotopes. The critical constants thus obtained are T/sub C/ = 641.7 K, P/sub C/ = 21.41 MPa, and p/sub C/ = 393 kg/m/sup 3/. An equation for the saturation vapor pressure of T/sub 2/O has been developed. The uncertainty of this equation has been developed. The uncertainty of this equation has been estimated at +-0.4% in the entire temperature range.","PeriodicalId":13548,"journal":{"name":"Industrial & Engineering Chemistry Fundamentals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1986-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76224272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sanders","doi":"10.1021/I100021A027","DOIUrl":"https://doi.org/10.1021/I100021A027","url":null,"abstract":"Heavy hydrocarbons (M/sub R/ > 250) have been observed to dissolve in liquid water just below its critical temperature (374 /sup 0/C). Visual measurements of the solution temperatures of hydrocarbon/water systems confined in sealed quartz capillary tubes (autogenous pressure) show unambiguously that even very heavy heavy hydrocarbons (M/sub R/ > 400) form true solutions with water in a temperature-pressure region where both pure components can exist as liquids. The solubilities determined from solution temperatures of three pure hydrocarbons (a straight-chain paraffin, n-tetracosane; a polynuclear aromatic, benzo(e)pyrene; an alkylbenzene, n-nonadecylbenzene) and a naphthene/branched paraffin white oil mixture are reported in the temperature range 320-365/sup 0/C. The solution-temperature-derived solubilities are in agreement with heavy oil fraction solubility data obtained in ''blind'' autoclaves. Solubilities of pure heavy hydrocarbons in water at 350/sup 0/C range from 1 wt % for n-tetracosane to 10 wt % for benzo(e)pyrene. The variation of hydrocarbon solubility in water as a function of temperature and hydrocarbon molecular size and type is discussed by using the concepts of hydrophobic interactions and solubility parameters which have been developed to explain the solubilities of light hydrocarbons in water.","PeriodicalId":13548,"journal":{"name":"Industrial & Engineering Chemistry Fundamentals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1986-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82852032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These advances have generally stimulated research leading to significant progress in the science of catalysis. Areas of catalysis providing good examples include ammonia synthesis in the chemical industry and catalytic cracking and reforming in the petroleum industry.
