I remember when I was a kid, my dad taking me to the plant in his town in northwestern Wisconsin that made coal oil. It smelled somewhat different than kerosene. They made oil for lamps and stoves before electricity. I remember the mountain of coal brought in by the trains outside the plant that would be brought in and process it inside somehow converting the coal into coal oil. I didn't know this was a new process...

I didn't know this was a new process...

My understanding is that it's basicly the same old process,
but dramaticly updated with new technology to make it both more efficient and compliant with environmental regulations.
