For Process Engineers

You engineer processes with CHEMCAD. With one of the Unit Operations provided here, you can enhance CHEMCAD with specific functionality.

Heat Exchangers

Cooling towers are used for the removal of heat through a partial evaporation of the coolant (commonly water).


Mixers

Bubble column reactors are multiphase reactors where the gas phase is dispersed in the liquid phase.

SPL (Single Phase Liquid) Mixer replaces the CHEMCAD Stream Mixer UnitOp (MIXE) with a model extended with calculation of fluid dynamics parameters and mixing quality.

Spray dryers are mostly used for powder formation while a slurry or an undersaturated liquid is passed through hot air. Spray dryers are used to achieve a certain particle size distribution and for handling temperature sensitive materials during powder formation.…

Static mixer is a mixer, which is designed to show good plug-flow behavior with intensive radial mixing. Static mixer has applications in waste water treatment, food and petrochemical industries.


Reactors

Bubble column reactors are multiphase reactors where the gas phase is dispersed in the liquid phase.

The fixed bed reactor is a type of heterogeneous catalytic reactor.

Fluidised bed reactors are multi-phase reactors, where the reactor fluid is passed through the bed of catalyst granules at high velocities for solid suspension resulting in better mass and heat transfers. They have applications in petroleum, polymer and nuclear industries…

Solids Handling

Cross flow filtration is a type of cake filtration, during which solids get trapped into the filter-bed and filtrate gets released at the other end. Cross flow filtration has applications in reverse osmosis, nanofiltration, ultrafiltration and in number of physical-chemical…


Piping and Flow

An ejector is a pumping device with no moving parts, which uses the motion of a motive fluid to transport another fluid. Industrial applications of ejectors vary from maintaining sub atmospheric pressures in the process equipment, to using ejectors as…

Liquid ring pumps can be used for vacuum applications or for gas compression. This model will calculate pump performance parameters like NPSH (Net Positive Suction Head), total head, volumetric discharge rate, and power consumption.

This model is a type of solid transport equipment model. The model covers solid flows like pneumatic conveying, and conveying through chutes. Depending upon the type of transport the parameters like internal pressure, allowable working stress and fluid mechanics parameters…
