'''Chemical process modeling''' is a [[computer modeling]] technique used in [[chemical engineering]] [[Process design (chemical engineering)|process design]]. It typically involves using purpose-built software to define a system of interconnected components,<ref name=":0">{{Citarcite web|url=http://en.processium.com/process-simulation/chemical-process-simulation.htm|titulotitle=Chemical process simulation : Processium, process simulation (chemical process simulation and conception)|data=|acessodataaccess-date=2017-06-24|obrawork=Processium|publicadolanguage=en|ultimoarchiveurl=https://web.archive.org/web/20150710045707/http://en.processium.com/process-simulation/chemical-process-simulation.htm#|primeiroarchivedate=2015-07-10|linguaurl-status=endead}}</ref> which are then solved so that the [[Steady state|steady-state]] or dynamic behavior of the system can be predicted. The system components and connections are represented as a [[Process Flow diagram|process flow diagram]].<ref name=":0" /> Simulations can be as simple as the mixing of two substances in a tank, or as complex as an entire [[alumina]] refinery.<ref>{{citarcite web|url=http://icsoba.org/sites/default/files/2015paper/aluminapapers/AA10%20-%20Process%20simulation%20in%20VM-CBA%20alumina%20refinery.pdf|titulotitle=Process simulation in VM-CBA alumina refinery|data=|acessodataaccess-date=2017-06-24|publicadopublisher=The International Committee for Study of Bauxite, Alumina & Aluminium|ultimolast=Franco|primeirofirst=Thiago|ultimo2last2=Seno Jr.|primeiro2first2=Roberto|ultimo3last3=Moreno|primeiro3first3=Rodrigo|ultimo4last4=van Deursen|primeiro4first4=Caio|ultimo5last5=Freitas|primeiro5first5=Alexandre|archive-url=https://web.archive.org/web/20160829015817/http://icsoba.org/sites/default/files/2015paper/aluminapapers/AA10%20-%20Process%20simulation%20in%20VM-CBA%20alumina%20refinery.pdf|archive-date=2016-08-29|url-status=dead}}</ref>
Chemical process modeling requires a knowledge of the properties of the chemicals involved in the simulation,<ref name=":0" /> as well as the physical properties and characteristics of the components of the system, such as tanks, pumps, pipes, pressure vessels, and so on.
