Today’s refineries must supply ultra-low sulfur fuels to the markets, and the favored method for accomplishing this is hydrotreating. This process has reached a high level of importance due to these requirements. Optimum performance coupled with long run lengths is necessary for the current environment.
This course covers all aspects of this process, including overviews, process flows and chemistry, catalysts, equipment, and proper operation. The class has a practical, operational focus that is suitable for unit engineers, supervision and operators, both experienced and inexperienced.
