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, pipeline management systems, production management systems, digital twins.
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5]
It is also used in ice packs to convert the water used as the cooling agent into a gel, in order to reduce spillage in case the ice pack leaks. [10] Sodium polyacrylate has also been studied for utilization in many applications such as nanofiltration of water to absorb water and concentrate the liquid with microbes. [ 11 ]
Aspen HYSYS (or simply HYSYS) is a chemical process simulator currently developed by AspenTech used to mathematically model chemical processes, ...
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 less volatile ones in a feed followed by condensation ...
Most venturi systems operate with an L/G ratio of 0.4 to 1.3 L/m 3 (3 to 10 gal/1000 ft 3). [4] L/G ratios less than 0.4 L/m 3 (3 gal/1000 ft 3) are usually not sufficient to cover the throat, and adding more than 1.3 L/m 3 (10 gal/1000 ft 3) does not usually significantly improve particle collection efficiency.
In high energy physics experiments, an absorber is a block of material used to absorb some of the energy of an incident particle in an experiment. Absorbers can be made of a variety of materials, depending on the purpose; lead , tungsten and liquid hydrogen are common choices. [ 1 ]
The pressure swing adsorption (PSA) process is based on the phenomenon that under high pressure, gases tend to be trapped onto solid surfaces, i.e. to be "adsorbed". The higher the pressure, the more gas is adsorbed.
