List of chemical process simulators. This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators ...
Aspen HYSYS (or simply HYSYS) is a chemical process simulator currently developed by AspenTech used to mathematically model chemical processes, from unit operations to full chemical plants and refineries. HYSYS is able to perform many of the core calculations of chemical engineering, including those concerned with mass balance, energy balance ...
UNIQUAC. In statistical thermodynamics, UNIQUAC (a portmanteau of uni versal qua si c hemical) is an activity coefficient model used in description of phase equilibria. [ 1 ][ 2 ] The model is a so-called lattice model and has been derived from a first order approximation of interacting molecule surfaces.
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.
Integrated asset modelling ( IAM) is the generic term used in the oil industry for computer modelling of both the subsurface and the surface elements of a field development. Historically the reservoir has always been modelled separately from the surface network and the facilities. In order to capture the interaction between those two or more ...
Ostwald process. The Ostwald process is a chemical process used for making nitric acid (HNO 3). [1] The Ostwald process is a mainstay of the modern chemical industry, and it provides the main raw material for the most common type of fertilizer production. [2] Historically and practically, the Ostwald process is closely associated with the Haber ...
Modeling and simulation of batch distillation unit. Aspen Plus, Aspen HYSYS, ChemCad and MATLAB, PRO are the commonly used process simulators for modeling, simulation and optimization of a distillation process in the chemical industries. [1] [2] Distillation is the technique of preferential separation of the more volatile components from the ...
The CAPE-OPEN, European Union funded, project was established in 1997. [1] The project involved participants from a number of companies from the process industries (Bayer, BASF, BP, DuPont, French Institute of Petroleum (IFP), Elf Aquitaine, and Imperial Chemical Industries (ICI)) together with 15 partners including software vendors (Aspen Technology, Hyprotech Ltd, QuantiSci and SimSci]) and ...
