Solvent dewaxing VS enhanced cracking
Thread Content
Hello everyone. Regarding the current processes for producing lubricant base oils, is dewaxing still widely used in the refining stage? Is there a trend in the future for it to be replaced by hydrogenation? Thank you.
Currently, the usage of Type 1 oil is roughly similar to that of Type 2 oil, but the amount of Type 2 oil is increasing rapidly. Due to its inferior properties and the severe pollution caused by the old production processes, I believe Type 1 oil will soon be replaced by hydrogenation processes.
