Carbon capture and storage (CCS) has attracted renewed interest in the re-evaluation of equations state (EoS) for prediction thermodynamic properties. This study also evaluates EoS Peng–Robinson (PR) Soave–Redlich–Kwong (SRK) their capability to predict properties CO2-rich mixtures. The investigation was carried out using machine learning such as an artificial neural network (ANN) a classified ...

New isothermal vapor–liquid equilibrium (VLE) data for the carbon dioxide + 1,4-dioxane system are reported at four temperatures (323.15, 333.15, 343.15, and 353.15) K pressures up to 122.7 bar. The critical curve was also measured 158.8 bar 420.15 K. Phase behavior measurements were performed in a high-pressure windowed cell with variable volume, using static-analytical method phases sampling ...

solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. therefore,...

From 1 August 2001 to 31 July 2004, 137 patients were referred from the Association Concerning Sexual Violence Against Women to the Accident and Emergency Department at the Kwong Wah Hospital for alleged rape. Approximately half of the patients presented within 3 days of the alleged assault. Fifty-one patients were prescribed emergency contraception: one patient remained pregnant despite treatm...

The theoretical performance of ionic-liquid(IL-) based working fluids in an absorption refrigeration system was investigated. The IL 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) and five hydrofluorocarbons (HFCs) were selected as the absorbent and refrigerant, respectively. The Redlich−Kwong equation of state and two-phase pressure-drop model were used to compute the thermodyna...

The radix-2 decimation-in-time (DIT) fast Hartley transform algorithm for computing the Discrete Hartley Transform (DHT) was introduced by Bracewell. DIT and decimation-in-frequency (DIF) algorithms were further developed by Meckelburg and Lipka, Prado, Sorenson et al, Kwong and Shiu. In these algorithms, the stage structures perform all the additions and multiplications and utilize stage depen...

The paper presents some specific applications of cubic equations of state (EOS) in Norak Hydro and points out some aspects of such equations that one should be aware of when using them or when developing new equations. Is is emphasized that the use of EOS to calculate vapor-liquid equilibrium is inherently empirical. Activity coefficients predicted’ for some systems by the Soave-Redlich-Kwong (...

ii ACKNOWLEDGEMENTS It has been a great privilege to be a graduate student in the Electrical and Computer Engineering department at the Texas Tech University and work closely with my advisor Prof. Dr. Kwong S. Chao. His keen insight into system and integrated circuit design is the key factor in the success of this research. I would also like to thank Prof. Dr. Sunanda Mitra, for her willingness...

Mixtures of carbon dioxide and secondary butyl alcohol at high pressures are interesting for a range of industrial applications. Therefore, it is important to have trustworthy experimental data on the high-pressure phase behavior of this mixture over a wide range of temperatures. In addition, an accurate thermodynamic model is necessary for the optimal design and operation of processes. In this...
