Gas Extraction, Softcover reprint of the original 1st ed. 1994 An Introduction to Fundamentals of Supercritical Fluids and the Application to Separation Processes Topics in Physical Chemistry Series, Vol. 4

Application of compressed gases as solvents has found widespread interest within the scientific community. Its processes have industrial applications.
Gas Extraction deals with the possibilities of supercritical gases as solvents for separation processes. The volume combines physico-chemical aspects with chemical engineering methods. The text generalizes as far as possible, and treats examples in detail.
Gas Extraction covers, for the first time, the subject in textbook form. Most of the examples provide new results that will be helpful for practicing scientists, engineers, and students who want to make use of the techniques.
