Gas absorption is a very ubiquitous unit operation in any chemical plant. It has in common with liquid-liquid extraction that there are two carrier streams and one solute to be partioned between them. Here, we use the McCabe and Thiele graphical method to study the separation of acetone from air....

nu_corrector is a tool for correcting intensity non-uniformity artifact of image. Here, non-uniformity refers to image artifacts of vignetting and bias (e.g. intensity inhomogeneity, illumination etc.). This tool is an implementation of our single-image based vignetting or bias correction systems...
