WebOil Refining C₅/C₆ Isomerization C₅/C₆ isomerization is a must-have for refiners who want to maximize the profitability of their gasoline pool. This process can be adapted to various configurations and allows improving C₅/C₆ naphtha cut octane numbers up to 92 without constraints on olefins and sulfur. Download Commercial Bulletin Over 95 WebIn many refineries, pressure swing adsorption (PSA) units play a major role in the final H 2 purification process. A US refinery has installed a variety of technologies to measure H 2 purity at the outlet of a PSA process unit. Initially, the plant used a commercial SG meter for this measurement. However, due to the non-binary nature of the ...
