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 ...
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.
Honeywell was also able to hire a number of HYSYS developers, ultimately mobilizing these resources to produce UniSim. [11] The divestment agreement specified that Aspentech would retain rights to market and develop most Hyprotech products (including HYSYS) royalty-free. [12] As of 2024, AspenTech continues to produce HYSYS. [13]
Founded in 1981, AspenTech was born out of a joint research project between the Massachusetts Institute of Technology (MIT) and US Department of Energy—called the Advanced System for Process Engineering (ASPEN) Project.
Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
Refineries often use PSA technology in the removal of hydrogen sulfide (H 2 S) from hydrogen feed and recycle streams of hydrotreating and hydrocracking units. Another application of PSA is the separation of carbon dioxide from biogas to increase the methane (CH 4) ratio. Distribution of oxygen produced by a primary line coming from a PSA plant
Lean, water-free glycol (purity >99%) is fed to the top of an absorber (also known as a "glycol contactor") where it is contacted with the wet natural gas stream. The glycol removes water from the natural gas by physical absorption and is carried out the bottom of the column.
Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
