ABSTRACT:
A liquid/dense gas extraction column process providing intimate contact between a dense gas and a fluid feed containing a solute and operating in an enhanced solubility region provides solubility of a solute in the dense gas to be at least 250% by weight greater than the solubility of the solute in the dense gas at the same operating temperature and 200 bar pressure. The enhanced solubility region for carbon dioxide is a pressure range of between 450 and 1200 bar in combination with a temperature range between 50 and 300.degree. C. The column has a diameter greater than about 3.5 centimeters and a height to diameter ratio greater than about 5.
