To learn more on applications of K-values and their impact on facilities calculation, design and surveillance, refer to JMC books and enroll in our G4 (Gas Conditioning and Processing) and G5 (Gas Conditioning and Processing вЂ“ Special) courses. Many less than desirable systems results from failure to recognize this.

This is important, for in many systems a series of VLE calculations is made the output from one is the input to another. K (or DePriester) Chart (high T range) in SI Units from Chemical Engineering Progress (by AIChE), Vol. The compositional analysis on which the calculation was based will often be in error more than this. There are several methods available for this purpose (See pages 113-116 of Vol 1 of JMC Books).ДЄn experienced practitioner usually can predict the quantity of a specified liquid within 6% (for a specified analysis and conditions). It is most important that the K-values be internally consistent. It is doubtful if one ever will encounter the analyses, flow rates and exact other conditions used as the design basis. However, the question arises as to which. The methods presented were the GPA correlations and charts, RaoultвЂ™s law, WilsonвЂ™s correlation, EoS approaches, activity coefficient models and JMC Charts and Tables.

This range, rather than one set of вЂњmagicвЂќ numbers, is then used to size equipment. In the previous Tip of the Month, we presented several methods for estimating Kvalues. Generally, crude oil and NGL phase behavior is handled by different models.ДЄll K-values are sensitive to composition, particularly the very volatile components like nitrogen, methane, and ethane.ДЇor design purposes, several models may be used to determine a range of results.

An experienced practitioner may have two or three different models or program available. There is no single K-Value correlation that is superior for all mixtures encountered. The accuracy of the results of calculations involving K-Values depends on the reliability of sampling, of the analysis of that sample, and the K-Value correlation used. Therefore, the following guidelines extracted from page 128 of Vol 1 of JMC book are suggested. Again, the calculated liquid fractions by the RaoultвЂ™s law and Wilson correlations are close to each other but they deviate considerably from the GPA charts and the SRK EoS results.Дue to the observation made in the previous section and other studies, care must be taken in selecting K-values correlations. DMSO is a promising solvent for separating the azeotrope of isobutyl alcohol and isobutyl acetate by extractive distillation.Similarly, for the same mixture shown in Table 1, a series of flash calculations for two isotherms were performed and the calculated liquid fractions (L/F) using different methods are compared in Table 5. The relative volatility of isobutyl acetate to isobutyl alcohol can be greatly increased by DMSO and the azeotropic point of isobutyl acetate and isobutyl alcohol will disappear if the mole fraction of DMSO is greater than 0.36. The VLE data for the binary and ternary systems predicted by the correlated interaction parameters were in good agreement with all the experimental data. The ternary VLE behavior were successfully predicted by the correlated binary parameters. The VLE data of binary systems were correlated with NRTL, UNIQUAC, and Wilson models. Ternary VLE data passed Wisniak point test. All of the binary VLE data passed WisniakвЂ™s modifed Herington area test and Wisniak point and area test. The isobaric vaporвЂ“liquid equilibrium (VLE) data for the binary systems isobutyl alcohol + dimethyl sulfoxide (DMSO), isobutyl acetate + DMSO, and ternary system isobutyl alcohol + isobutyl acetate + DMSO were measured at 101.3 kPa.
