Program information

Chemical Engineering (CE) is a discipline mainly based on Chemistry, Physic and Mathematic. In CE process modelling and process calculation are very important.

The programs below show that LB can be used to do complicated calculations. All programs are designed to solve a specific problem and in most cases show the result in a graph. All programs are delivered with source code, tkn and a dat-file of type random access (RA). After opening the program and pressing the start button the calculation based on data in pos 1 of the RA-file takes place. The user can choose other data in the RA-file and also save new data to the file.

For users with LB4.03 the program can be run in bas-mode. The default mode is tkn and for this no LB has to be installed on the PC

 

Each of the packages below must be unzipped into a separate Directory to avoid duplication of files.

Then the runtime files in IBMenu must be unzipped with each package, and the MENU.EXE activated.
