Testimonials about WinSim's Process Simulation Solutions
Process Tech, Inc. (PTI) has been using WinSim's Design II process simulator since early 1996 to design, optimize and analyze many processes in the Hydrocarbon Processing Industry (HPI). This work includes:
Design II is the heart of Tourtellotte and Associates LLC consulting services. We have been using Design II for Window since 1992. We consider Design II to be the best presentation of Perry's Chemical Engineers' Handbook in software format. In addition to the data base of 1000 compounds , the ChemTran module provides the tools to create the thermodynamic and physical properties for most any compound that one can write a formula.
Ascent Engineering has been using Design II from Winsim since November, 1998. We have used Design II to simulate crude and vacuum units, an FCC main fractionator, absorber-strippers, debutanizers, a naphtha stabilizer, amine absorbers, and numerous other towers. Design II has performed admirably in every case. The results generated by Design II are quite consistent with other, higher priced simulators.
Winsim support has been very responsive to our needs, always responding quickly to requests for support. Technical questions emailed to the support staff have always been responded to within 24 hours, and typically within half a day. They have listened to our requests for additional features, continually adding new capabilities and improving old ones. Any software problems that have cropped up have always been quickly corrected.
We are happy to recommend this software.
The first jobs our firm handled was distillation of aqueous ethanol for use as automotive fuel "gasohol" in 1981. At that time we were introduced to ChemShare's DESIGN II. We were in an era when simulations like this was done on a remote mainframe computer (ChemShare's) PRIME 2250 at 300 baud transmission rates. You queued the job in the morning and sat waiting for results the rest of the day.
In the 25 years we have seen un-parallel growth in computers , as well as, the software. To what if scenarios are just a key stroke away. Today you can develop a mirror like image of most petrochemical and refinery processes. For the last fifteen years we use DESIGN II exclusively on ALL jobs. Some of the applications we have used DESIGN II is for:
We have used virtually all the features of the simulator and are very satisfied with its capabilities and technical support.

The Design II simulator is fast, accurate and comprehensive. It is easy to use and the technical support is always right there. An email answer to any question can be expected within a matter of hours. They are responsive to requests for new features. Highly recommended.

I use Design II for Windows since 2001. Since then I successfully simulated:
Organic group manager,
WinSim Inc. Design II process simulation software offers users incredible chemical plant modeling for existing process evaluation as well as for designing plant retrofits for production capacity and efficiency improvements. The software includes all unit operations of chemical engineering at incredibly low cost, compared with other vendors process engineering simulator software. Tremendous time savings result from the replacement of older process simulation software with Design II, giving engineers more time to study plant improvement alternatives. Design II simulation results are in very close agreement with other process simulator programs and the reports provide excellent support of detail of calculations for client project documentation. Chem-Engineering Services replaced another process simulator used for 15 years with Design II in April 2000, gaining tremendous new advantages. Design II provides engineers with extensive thermodynamic methods and fluid properties options for most every chemical process. The Design II simulator is versatile, efficient and produces quick, reliable answers for todays chemical engineering needs in a very easy-to-use Microsoft Windows format.

The Process Group, LLC has used WinSim Design II software for over six years on a wide range of projects in the hydrocarbon, power, oil & gas production, chemicals and food industries. We use the program to simulate process systems, including major refinery units for new and revamp projects, power generation from waste gas streams using cogeneration technology, offshore and onshore oil and gas treating, glycol dehydration and energy recovery projects.
The principal advantage of the software is its ease of use and excellent technical support. We have never waited more than a few hours to receive answers to our questions or help in getting a simulation to run.
The thermodynamic packages available are second to none and offer a full range of methodologies to accurately generate properties from heavy crude oils to light ends gas streams. The use of Chemtran data base files for specialized operations such as amine and glycol units is especially helpful, and alleviates the need to use expensive specialized software for these unit operations.
We would recommend this software to any user in the refining, oil & gas, power sectors or any industrial/manufacturing facility were hydrocarbons, gas, steam, flue gas or other utility system needs to be modeled. This includes projects involving heat recovery, fractionation, separations, pipelines, flare/relief systems, boilers/steam systems, gas compression, dehydration and treating, waste water stripping, and modeling systems to generate data for inclusion in environmental permitting.
For small businesses, consultants or process engineers in major firms, this software is easily justified and is becoming the gold standard for those who want value and service in the same package.

For your interest, I have found Design II to be a very good teaching and learning tool for the students. A positive feature (from my perspective) is its user-friendliness when it comes to report writing. One can move effortlessly between Design II and Word and extract any graphics and specific data needed for the report.
