Water Purification by Silver Complexation

Many industrial processes leave remainders of toxic dissolved metal ions in process flows. A common method for removing metal ions from water is complexation. This model example shows a purification reactor where silver ions are complexated to diamine-silver for removal. Ammonia (L) is added across a membrane in a tubular reactor in order to remove silver ions (M) from a water stream. A ...

Fine Chemical Production in a Plate Reactor

Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting fluid. For instance, this means that the heat released from strongly exothermic reactions can be readily dissipated ...

Isoelectric Separation

This modeling example applies the Transport of Diluted Species interface to model a separation process. A stream containing six different ionic species is divided into pure component streams by means of migrative transport in an electric field. Free flow electrophoresis can be used to separate macromolecules such as proteins, based on their mobility perpendicular to the flow of the carrier fluid. ...

Transport and Reaction in a Catalyst in 3D

Consider the study of a mass balance of a diluted species in air, for example, a pollutant in an exhaust stream. The model’s aim is to calculate the concentration profile of this species, which is decomposed by a catalyst present on the surface of a porous supporting structure. In a first step, you solve the velocity field for the solution assuming that the diluted pollutant has no influence ...

Nonisothermal HI Reactor

In the case of a perfectly mixed nonisothermal system, you have to set up both the time-dependent material and energy balances. There are no spatial concentration gradients because the system is perfectly mixed, so the Reaction Engineering interface can create a model without evaluating the material-transport properties.

Biosensor Design - new

A flow cell in a biosensor contains an array of micropillars. The concave surfaces of the pillars are coated with an active material that selectively adsorbs biomolecules in the sample stream. This application allows the user to change the design of the sensor by altering input parameters such as pillar diameter, grid spacing, and inlet velocity, and see how it affects the detection results.

Neutralization of Chlorine in a Scrubber

This example studies the kinetics of the neutralization of chlorine gas in water solution. The model assumes that the fluid volume is perfectly mixed and constant. This means that the chlorine has dissolved to an almost saturated state (1·10-2 mol/m3) and that the hydroxide has also mixed well throughout, as would be the case for a very small amount of fluid in a scrubber. The study allows ...

Polymerization in Multijet Tubular Reactor

In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are quite common in the production of polymers, and the complex interplay between fluid dynamics and fast chemical ...
