glass distillation column oil refinery are mainly used in laboratories or small-scale refining scenarios, rather than as core equipment in large petroleum refineries. 

Industrial grade glass distillation column oil refinery usually uses distillation towers made of stainless steel or metal materials, while glass distillation columns are often used for experimental research and development, essential oil extraction, or teaching purposes due to pressure and temperature resistance limitations.

glass distillation column oil refinery are mainly used in laboratory environments for solvent recovery, waste oil regeneration research, or natural product (such as vegetable oil) distillation
