CC--THERM (Heat Exchanger Design Rating Software)
It's easy because it's a CHEMCAD program...
If you know how to use CHEMCAD, you know how to use 95% of CHEMCAD-THERM, so the usual new program learning curve is virtually eliminated. Extensive help facilities are provided. Data is entered using intelligent input procedures and dialog boxes.
Throughout the processing industry, it's a well-known fact that no other simulation programs come close to CHEMCAD programs for ease-of-use.
It's easy because it's integrated...
In heat exchanger program, integration means accuracy, and accuracy starts with entering the process data. Here's where you'll really appreciate CHEMCAD-THERM's full integration, because process data is automatically transferred from CHEMCAD's flowsheets.
Plus, of course, automatic data transfer eliminated the tedium and invariable inaccuracies of manual data transfer.
Best of all, CC-THERM uses the same Thermodynamics routines and physical properties databases as CHEMCAD. the problems and inconsistencies that typically occur when processes are designed using different programs are totally eliminated with CHEMCAD-THERM.
It's easy because the expertise is built in...
Built-in expertise means two things: First, CHEMCAD-THERM is rigorous and comprehensive. it's designed to handle your most complex heat exchanger rating or design, and we mean the hard problems. CC-THERM takes no short cuts, makes no assumptions, runs a full zone analysis and stringent stream anlayses. And like all CHEMCAD programs, CC-THERM run fast.
Second, the program is intuitive in operation. Process engineers continually tell us how much they learn about heat transfer analysis just by using CHEMCAD-THERM. With our HELP and our step-by-step data input screens, you can have an exceptionally high level of confidence in the accuracy of your rating or design.
So whether you work with heat exchanger problems daily or only occasionally, you'll enjoy that rare combination of power and simplicity that comes with CHEMCAD-THERM.

CC--ReACS (Dynamic Batch Reactor Control Simulation Software)
From experiment to production
CC-ReACS's flexibility makes it the ideal simulator at all stages of the design process, from laboratory experimentation through scale-up, yield optimization, hazard analysis and control. it can model vessels ranging from laboratory glassware or reaction calorimeters to pilot or production scale reactors under a wide range of operating conditions.
The cost savings that can be achieved by improving the results of your pilot plant, or by going directly from table top to full scale, can be significant.
Special options allow the chemical system to be separated from the plant model so the chemist can study the behavior of the chemist can study the behavior or the reacting system under adiabatic or isothermal conditions. Engineers can swiftly carry out scale-up calculations by building upon this model. A wide range of alternative production routes and operating strategies can be examined in detail, and extensive thermal safety studies can be implemented.
Technical power
CC-ReACS offers an impressive list of features,which makes it possible to simulate almost any chemical system in any reactor. This is accomplished by combining a unique interface which understands the process chemistry with a sophisticated reactor model which contains options for multiple jackets, internal and external coils, and heat exchanger. CC-ReACS simulated batch, semi-batch or continuous reactor operation using a flexible sequencing and PID control system.
Reactive distillation
Together with Chemstations' fully integrated dynamic distillation model, CC-DCOLUMN, CC-ReACS can rigorously simulate combined reactor/distillation system.
This feature offers equilibrium based or mass transfer based simulation for packing and trays. This powerful combination, CC-ReACS gives you a head start in tackling reactive distillation problems.
Kinetic rate regression
CC-ReACS rate regression facility enables you to determine the rate parameters from imported experimental data. This data can be any combination of temperature, concentration, volume or heat release data from as many experiments as you have available. No other software package enables you to easily fit this much data in s single run.

CC-DCOLUMN (Dynamic Distillation Control Simulation Software)
CHEMCAD-DCOLUMN is fast, accurate, applicable to a wide range of processes, and easy to learn and use. It is fully integated with CHEMCAD, which can perform steady-state simulation, equipment design, and DIERS analysis. This allows you to move easily around and between all aspects of your design. Only in such an

environment can you achieve the really big paybacks the dynamic studies can provide.
Steady state simulation miss the dynamic aspects of process design such as operability, the impact of disturbances, and many facets of safety issues. These are important selection criteria for any process and the inability to fully underatand them generally leads to over designs which cost millions of dollars in both capital and operating costs.
For example, from a steady-state viewpoint it is better to minimize holdup in processing equipment. Holdup means larger equipment, which means larger fixed capital. From an operational standpoint, however, holdup can make the difference between a smooth working plant and an inoperable one. In operations, holdup means isolation from disturbances, and may mean being able to run one section of the plant when another is down. However, too much holdup means long process cycle-item causing corrections to quality problems to take longer. So there are important tradeoffs.
The abiltiy to perform dynamic simulations means that these tradeoffs can be evaluated early in the design before any decisions have been made. Thus, from the beginning you will be albe to quantify the requirements of operability, control loop tuning, changes in throughput or ambient conditions, safety demands etc. This will save you money not just in capital investments, but also in production costs. 
A plant which is designed with operability in mind can produce considerably more than a plant where operability issues were never explicity addressed.

CC-SAFETY NET (Piping & Safety Relief Network Simulation Software)
CC-SAFETY NET is an engineering software tool designed to simulate the steady state behavior of pressure relief devices and piping systems under actual flowing conditions. It also provides powerful facilities for environmental audits in the prediction of volatile organic compound (VOC) emissions to atmosphere at equilibrium conditions.

The DIERS (Design Institute for Emergency Relief Systems) facility of CC-SAFETY NET provides the user with the latest technology in the sizing and analysis of safety relief vents in emergency situations. This technology is complex and difficult for the average engineer to understand and apply. CC-SAFETY NET ensures that you get reliable results because:
Chemstations has spent years studying DIERS and consulting with experts in the field. We are thus able to provide you with a tool which is not only comprehensive and accurate, but which also separates the useable from the purely theoretical providing you with a practical, real world tool.CC-SAFETY DIERS facility has been used in the field for years.
PIPING NETWORKS:
CC-SAFETY NET will simulate any type of steady state piping network. Flow loops, distribution systems, and collection networks can all be assembled and simulated in any combineation. These networks can also include:
