چکیده
A continuous flow apparatus was applied to measure the phase equilibrium at 523 K and 573 K. The performance of analysed with determination vapor pressures water temperatures ( T = 453 473 K). measured deviated from literature values less than 1 %. Vapor n -dodecane, -hexadecane phenol were 523–623 K) and, bubble point -dodecane + pure components compared values. Relative pressure value 2 % for all pressures. in this work agreed well literature, which indicates that measurement method can produce good-quality data. systems modeled Peng-Robinson Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equations state Non-random Two-liquid (NRTL) activity coefficient model. first without binary interaction parameters. Additionally, parameters regressed optimize models. NRTL model described behaviour data better state. Furthermore, equation resulted predictions PC-SAFT even regression. Both system well. showed azeotropic behaviour.

(Liquid + Liquid) Equilibrium for Ternary System of (Water + Phenol + Cyclohexane) at T = 298.2 K
Experimental solubility curves and tie-line data for the (water + phenol + 2-ethyl-1-hexanol) system was obtained at T = 298.2 K and atmospheric pressure. The tie-line data was determined by techniques karl-fischer and refractometry. This ternary system exhibits type-2 behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting ability of the solve...
متن کاملDispersive Ordering and k-out-of-n Systems
Extended Abstract. The simplest and the most common way of comparing two random variables is through their means and variances. It may happen that in some cases the median of X is larger than that of Y, while the mean of X is smaller than the mean of Y. However, this confusion will not arise if the random variables are stochastically ordered. Similarly, the same may happen if one would like to ...
متن کاملOn the Joint Reliability Importance for k-out-of-n Systems
In this paper, the concept of joint reliability importance (JRI) of two or groups of components in a coherent system with independent components have been studied. The JRI is defined as the rate at which the system reliability improves as the reliabilities of the two or groups of components improve. Generally, the sign and the value of the JRI represent the type and the degree of i...
