  • Assessment test for Glycol Loss in gaseous system
    Fuel Processing Technology, 2013
    Co-Authors: Farhad Gharagheizi, Ali Eslamimanesh, Amir H. Mohammadi, Somayeh Eskandari, Dominique Richon
    Abstract:

    Abstract We herein apply a mathematical method for detection of the outliers in experimental phase equilibrium data of ethylene/triethylene Glycol (EG/TEG) solubility in a gaseous system. Four Chrastil-type correlations including the original Chrastil, Adachi and Lu, del Valle and Aguilera, and Mendez-Santiago and Teja are used to represent/predict the phase equilibria of the EG/TEG + carbon dioxide/methane systems. It is found that the employed correlations are statistically valid, one experimental solubility datum from the solubility data of the carbon dioxide + EG system might be doubtful, two data points may be referred to be the outliers evaluated by the Mendez-Santiago and Teja correlation and one data point from the same dataset is found to be out of applicability domain of the Adachi and Lu and the Mendez-Santiago and Teja correlations.

  • Glycol Loss in a Gaseous System: Thermodynamic Assessment Test of Experimental Solubility Data
    Journal of Chemical and Engineering Data, 2011
    Co-Authors: Amir H. Mohammadi, Ali Eslamimanesh, Mohammad Yazdizadeh, Dominique Richon
    Abstract:

    Triethylene Glycol (TEG) is generally used to adjust the water dew point in natural gas processes. Unfortunately, only very few sets of experimental data regarding solubilities of these humidity absorbents in supercritical natural gas components have been reported in the literature partly due to the difficulties in such very low concentration measurements. Therefore, a satisfactory accuracy of measurements is not obvious, and the reliability of the corresponding data must be checked prior to their application. In this study, we focus on presenting the results of a thermodynamic assessment test (consistency test) for experimental solubility data of triethylene Glycol in supercritical methane and carbon dioxide. The Gibbs Duhem equation in terms of pressure, fugacity coefficients, solubilities of triethylene Glycol in gas phase, and compressibility factor of gas phase is applied for the consistency test. The Soave-Redlich-Kwong (SRK) equation of state (EoS) along with the van der Waals (vdW2) mixing rules is used to represent the corresponding solubilities. The results show that three sets of the four investigated experimental data sets are thermodynamically consistent, while one data set is not fully consistent.

  • Chrastil-Type Approach for Representation of Glycol Loss in Gaseous System
    Industrial & Engineering Chemistry Research, 2011
    Co-Authors: Ali Eslamimanesh, Amir H. Mohammadi, Mohammad Yazdizadeh, Dominique Richon
    Abstract:

    Glycols are generally used to adjust the water dew-point in natural gas processes to avoid gas hydrate/ice/condensate formation. Their vaporization Loss in gaseous systems may happen regularly in the petroleum industry. Glycols have very low solubility in the gas phase and because of difficulty of the corresponding measurement, few sets of experimental data are available in open literature and may not be fully satisfactory. In a previous work, we performed thermodynamic consistency tests in order to prepare reliable data sets for modeling purposes. Application of four widely used correlations in supercritical fluid industry, including the original Chrastil, Adachi and Lu, del Valle and Aguilera, and Mendez-Santiago and Teja, in which the effects of temperature, density of gas (solvent), and pressures on the solubility of Glycol are generally taken into account, are investigated to represent the corresponding solubility of ethylene Glycol and triethylene Glycol in supercritical methane and carbon dioxide b...

It is found that the absolute average deviations (AAD %) of the evaluated Glycols solubility by the aforementioned equations from 57 investigated experimental values are around 27%, 18%, 31%, and 17%, respectively.

  • Glycol Loss minimization for a natural gas dehydration plant under upset conditions
    Industrial & Engineering Chemistry Research, 2019
    Co-Authors: Emdadul Haque, Qiang Xu, Srinivas Palanki
    Abstract:

    Low-temperature separation with a monoethylene Glycol (MEG) injection process is a common dehydration technique for natural gas processing. However, the MEG-based dehydration system frequently suffers significant Glycol Loss during plant upset conditions, causing double penalties of economic Loss and air emissions. Thus, it is very important to minimize MEG Loss in the dehydration process. In this paper, an efficient and effective methodology to reduce MEG Loss under upset conditions of a natural gas dehydration plant has been developed. First, a plant-wide steady-state simulation model is developed and validated at normal operating conditions. Next, the root cause analysis for MEG Loss is performed by introducing various process upsets to the simulation model, which indicates that most MEG Loss is due to the fluctuating temperature of the stripper column overhead. After that, a plant-wide dynamic simulation model is developed to help generate a new control strategy to regulate the stripper column operati...
