The non-random two-liquid model [1] (abbreviated NRTL model) is an activity coefficient model introduced by Renon and Prausnitz in 1968 that correlates the activity coefficients of a compound with its mole fractions in the liquid phase concerned. It is frequently applied in the field of chemical engineering to calculate phase equilibria.
In the Oil and Gas, Petrochemical and Oil Refining industries, liquid-gas coalescers are widely used to remove water and hydrocarbon liquids to less than 0.011 mW (plus particulate matter to less than 0.3 μm in size) from natural gas to ensure natural gas quality and protect downstream equipment such as compressors, gas turbines, amine or ...
In recent years it has also been used in power system balancing models [1] and in power electronics. [2] Model predictive controllers rely on dynamic models of the process, most often linear empirical models obtained by system identification. The main advantage of MPC is the fact that it allows the current timeslot to be optimized, while ...
The Institute for Liquid Atomization and Spray Systems, (ILASS), is an organization of researchers, industrial practitioners and students engaged in professional activities connected with the spraying of liquids and slurries. Annual technical conferences are organized by each of the ILASS organizations ILASS-Americas, ILASS-Asia, and ILASS-Europe.
The successful prediction of a stock's future price could yield significant profit. The efficient market hypothesis suggests that stock prices reflect all currently available information and any price changes that are not based on newly revealed information thus are inherently unpredictable. Others disagree and those with this viewpoint possess ...
The Peerless odorizer was the first example of this type of odorizer. The Peerless natural-gas odorizer was recognized as a Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1992. [4] This odorizer was said to have been developed in response to the New London School explosion that occurred in March 1937.
It is common in the field of mass transfer system design and modeling to draw analogies between heat transfer and mass transfer. [2] However, a mass transfer-analogous definition of the effectiveness-NTU method requires some additional terms.
The challenge is the compromise between the resolution of the model and the computational efficiency, since all-atom simulations of big systems involving IDPs are still difficult to be performed. Moreover, the molecular interactions among IDPs in the droplet-state are still poorly understood, and the combination of experimental data and ...
