I would like to ask everyone, what methods are used for drying lignite before dry distillation?
Thread Content
Before upgrading lignite, what are some good manufacturers of drying equipment for use prior to carbonization, and what is their performance?
I work on the design of lignite drying processes; I have been responsible for designing several such projects. If you have specific questions, I’m happy to discuss them with you and learn from you as well*
Mechanical dewatering method: This method is used to dehydrate lignite under heat and pressure of approximately 100°C and less than 16 MPa. Operating under these pressure conditions requires high standards for equipment manufacturing, etc., but it results in the lowest energy consumption. This process is still only in the laboratory research stage, with no reports of industrial application.
