Phase Equilibrium of Ethanol + CO2and Acetone + CO2at Elevated Pressures

Phase equilibrium investigations of fluid systems at high pressures

Phase equilibrium and metastability of liquid benzene at high pressures.

This work is mainly an investigation of some of the liquid-to-solid properties of pure benzene on a restricted domain of high pressures (20.6< or =P< or =102.9 MPa). Newly obtained equilibrium experimental data and recently developed analytical equation of state are exploited and compared with each other and with previous experimental data. Curves fitted to the pressure, volume discontinuity, a...

A Subdivision Algorithm for Phase Equilibrium Calculations at High Pressures

Phase equilibrium calculations at high pressures have been a continuous challenge for scientists and engineers. Traditionally, this task has been performed by solving a system of nonlinear algebraic equations originating from isofugacity equations. The reliability and accuracy of the solutions are strongly dependent on the initial guess, especially due to the fact that the phase equilibrium pro...

Regeneration of СO2 Physical Solvents at Elevated Pressures in Gas-Liquid Membrane Contactor

In the present work, a membrane contactor with asymmetric flat-sheet poly(vinyltrimethylsilane) (PVTMS) membranes was proposed for the CO2 desorption process from physical solvents at elevated trans-membrane pressures. Different solvents were studied: water, a mixture of polyethylene g...

Antimicrobial Effects of Ethanol and Acetone Extracts of Plantago major Seed on Streptococcus mutans

Background and Aim: This study aimed to compare the effects of acetone and ethanolic extracts of Plantago major (P. major) on S. mutans.   Materials and Methods: In this in vitro study, the antibacterial effects of eight different concentrations of the acetone and ethanolic extracts of P. major seed were examined on S. mutans, and the minimum inhibitory concentration (MIC) and minimum bacte...
