Resembling gray boxes with white and red striped chimneys, a refinery is two blocks tall and accepts electricity through the bottom part. Although it may sometimes look like it is connected, power will not flow into the machine when active.
It is different from most other benches because it must be placed on a solid surface (block) and not unsupported on a back wall. However, a refinery will not drop when the block below it is removed. A refinery cannot be placed where there is glass panes.
When active, big, black particles will start coming out of the refinery instead of small, white particles.
Energy Usage
Refineries require electricity to function, and use quite a lot of power when active.
