Steam Turbine Retrofit
Steam Turbines in Hydroprocessing Units Hydroprocessing in the Oil & Gas industry refers to two separate, yet similar processing: hydrocracking and hydrotreating. The hydrocracking process converts a variety of petroleum fractions, including oil recovered from solvent extraction of petroleum residues into more valuable, lower-boiling fuel products. Hydrotreating refers to [...]
