Simproteck Corporation has released its latest drying software product, Simprosys 3.0. It is available for trial at www.simprotek.com.

Simprosys 3.0 supports combustion drying, general air drying and tipical enclosed inert gas (nitrogen) drying. It can model and simulate not only Air-Water system, but also Air-Ethanol, Nitrogen-Ethanol, Air-Carbon Tetrachloride, Air-Benzene, Air-Toluene, Air-Acetic Acid, Nitrogen-Acetic Acid, Nitrogen-Acetone, Nitrogen-Methanol, Nitrogen-N-Propanol, Nitrogen-Isopropanol, Nitrogen-N-Butanol, Nitrogen-Isobutanol systems.

Simprosys 3.0 includes 20 unit operations, namely solids dryer, liquid dryer, buner, cyclone, air filter, bag filter, electro-static precipitator, wet scrubber, scrubber condenser, fan/blower, compressor, steam jet ejector, pump, valve, heater, cooler, heat exchanger (which can be used as an evaporator), liquid-vapor separator, mixer and tee. It also includes a logical unit operation, viz. recycle, to simulate recycled gas or material stream, and two utilities, namely, humidity chart and unit converters. The humidity chart utility can be used to visualize either the state of a drying gas or an isenthalpic drying process. The unit converter utility can be used to convert any typical engineering units.

As a design engineer, you can use Simprosys 3.0 to design drying and evaporation related plants. Based on design requirements you can quickly layout the flowsheet and compute the heat and mass balance of the whole plant and obtain the necessary process parameters such as the air flow rate to the dryer, the capacity and power requirements for the blower, the drying fuel flow rate of the burner or heat duty of the heater, etc. As part of the balance calculation results the Thermal Efficiency and Specific Heat Consumption of the dryer(s) are automatically obtained. You can tweak the input and output values of different variables to optimize the dryer(s) and drying system. After the balance calculation is finalized, you then can choose equipment according to the simulation results.

As a process engineer, you can simulate existing plant by easily laying out the plant on a flowsheet and input the operating conditions to obtain the heat and mass balance calculation results. You can see how efficient current operation is according to the calculated Thermal Efficiency and Specific Heat Consumption of the dryer(s). You can try different operating conditions to optimize the operation. You can also use Simprosys 3.0 as an effective troubleshooting tool to find which unit is not working as designed.
