Free, Demo, and Share wares for Che Engineering

I found some softwares that can be very useful for chemical engineering students, lecturer or the pro ones. Some are freewares, some are demos, some are sharewares. For information, the freeware is a software which is free to download without necessary to buy it. And it is fully working. Demo is a software which is free to download but with limited using period or trial (from 15 days to one month). Some features are disable. Shareware is a demo software but without limited using period. They are all very helpful for me when I was still student to make my college assignments easier, to make me understand the theories easier, and to make learning funnier.

Write down a name of the below sofware into the search box of a search engine (like Google) followed by the phrase “free download” and click the search button. Find the related site of the software and click the download link. Follow the instruction to install it on your PC. Enjoy the searching!! Hunting the softwares itself is a fun thing.

The Chemical Kinetics Simulator (CKS) provides a rapid, interactive method to simulate chemical reaction mechanisms. It only requires basic information: the reaction mechanism and kinetics, intial concentrations, reactions conditions and several simulator setup parameters. Once a simulation is complete, you may select the types of data plots to display. The choices are concentration, temperature, pressure, and volume vs time or concentration, pressure, and volume vs temperature. (Freeware)

ChemEng Economics Calculator was mainly made to do the basic method of estimating the Net Present Value of a process plant. This easy to use software also include few small calculators such as Estimation of Total Plat Cost - Overall Basis, Exponential Estimation, Updating Estimates, Exponential Cost Estimating Total Plant Cost from Individual Cost Sections. (Demo)

Est$Pro was developed to serve a specific purpose, rapid conceptual cost estimating of process plants and equipment. It will estimate process equipment prices and also estimate the cost of purchasing and installing bulk materials that user defines. (Demo)

Basic Acid Titration and Equilibria – BATE is a program for pH calculations in mixtures of acids and bases, weak and strong, with or without ionic strength. BATE is able to calculate pH of any mixture of acid and base faster then you will be copying the results from the screen. Whether you need to prepare a solution, or examples for lecture, or you want to check your homework – BATE is as handy as possible (Demo)

ACDLabs 10.0 contains of three programs i.e ChemsSketch, 3D viewer, and ChemBasic. ACD/ChemSketch is the powerful all-purpose chemical drawing and graphics package from ACD/Labs developed to help chemists quickly and easily draw molecules, reactions, and schematic diagrams, calculate chemical properties, and design professional reports and presentations. ACD/3D Viewer is a fast yet accurate 3D modeling and visualization program. It is fully integrated with ACD/ChemSketch, allowing you to draw 2D structures and quickly obtain their 3D representations in a striking 16 color display. ChemBasic is a simple, convenient and functionally rich programming language for the presentation and manipulation of molecular structure, related objects and all the content of ACD/Labs’ current and future programs. ChemBasic is founded on, and fully integrated with, ACD/Labs existing functionality. At the same time, ChemBasic has all the things a programming language should have: numeric and string variables, arrays, flow control and conditional operators, input/output procedures, etc. (Freeware for educational purpose only)

ChemLab comes with a range of pre-designed lab experiments for general chemistry at the high school and college level. Users can expand upon the original lab set using ChemLab's LabWizard development tools, thus allowing for curriculum specific lab simulation development by educators. These user designed simulations combine both text based instructions and the simulation into a single distributable file. (Shareware)

Discounted Cash Flow Analysis Calculator is a capital budgeting and investment analysis tools which simultaneously evaluates 14 cash flow series comparing 5 different discount rates (or costs of capital) per series. For each series (or capital budgeting project) Discounted Cash Flow Analysis Calculator provides the following results: Initial Investment, Smallest Cash Flow, Largest Cash Flow, Cash Flow Range, Average Cash Flow, Number of Cash Flows, Undiscounted Sum of Cash Flows, Internal Rate of Return (IRR) and Undiscounted Payback Period. (Demo)

PackCol performs hydraulic design for new packed columns or rating calculations for existing columns and towers. The design basis can be approach to flood, maximum capacity or pressure drop. Includes a database of packing types, but custom data can be used. The Eckert and Robbins correlations are included to cover the full flowrate range. Results can be printed in tabular form, and plotted as a Generalised Pressure Drop Correlation diagram or as an Operating Diagram. Detailed manual and tutorial included in Word v6 format. (Demo)

Enjoy the softwares!! If you are interested, why don’t you contact the vendor and buy the original ones. I am not representation of the vendors.
