Heat Recovery in the preheating process of a liquid phase hydrogenation
The preheating of tar in a hydrogenation process was simulated for h-tec.
As a first step of the project physical properties of components were implemented into the simulation environment through regression. Extensive shell and tube simulations were conducted to calculate the U-values of the heat exchangers, which were subsequently validated through existing data.
As a result, PrimeUnit was able to determine the sensitivity of the main process regarding various bypasses.
CHEMCAD Integrated Excel Configurator for Projects & Engineering and Sales
Chemstations Europe GmbH and PrimeUnit GmbH maintain a strong partnership, due to the former employment of the whole founding team of PrimeUnit GmbH by Chemstations GmbH.skills of the Prime Unit engineers, in handling the process simulation software CHEMCAD.
The symposiums organized by Chemstations, CHEMCAD User Meetings and other lecture series are often enhanced by the presentations of the Prime Unit staff.
Fractional Batch Distillation
Fractional Batch Distillation provides the possibility of separating multiple component mixtures into its pure components by a single column. This process is demonstrated in the following tutorial, on the basis of a three component mixture of benzene, toluene and o-xylene. The simulation is applied in the stationary mode in the tutorial, but it can also be created dynamically via CC-DYNAMICS.
A typical use-case is demonstrated here by the separation of the ethanol-water mixture by using n-pentane as entrainer.
In the following tutorial the rectification process is fully modeled CHEMCAD and a brief outlook on possible optimization approaches is given.
For the separation of the mixtures behaving close to ideal, a shortcut simulation is to be carried out in order to estimate important parameters for the rectification column, in addition to the characteristic curves of the equipment and the location of the feed tray. In the following tutorial, a use-case example is simulated in CHEMCAD and the procedure is explained.
Rigorous Column Simulation - SCDS
Modeling and Simulation of a Hybrid Separation Process Consisting of Rectification in Combination with Pervaporation
The aim of this work is the modeling of a hybrid separation process, consisting of rectification and pervaporation. This is carried out by the implementation of the model in the simulation environment MOSAIC, and its simulation. With this hybrid process, the mixture of acetonitrile/water is separated acetonitrile is obtained in purest possible form.
