Issue description
It shows you can use chlorine in only one port, but also says you can import naphtha or ethanol through that port. If you did that though, you'd have no way to import the chlorine through pipes. It should be changed to chlorine only, or make them all any of the 3.
Expected behavior
Be logical.
Reproduction steps
Look at ports.
