Re: Oil extraction

Seems to me that if they used the bottom outlet, they would have to open the dome anyway to let air in as the tank emptied. And unless the tank was up on a trestle or was draining into an underground tank, they'd still have to pump it. So why mess with uncapping the bottom outlet, hooking up a hose, and opening the valve, when it could all be done through the dome?

I can only admire the ingenuity in engineering methods of heating and otherwise preparing the contents of a tank car for pressurized pumping of the material up and out of the dome. But why not let if flow by gravity and added pressure and/or heating if needed out of the bottom valve?. Why fight gravity at all, ingenious or not? Thank you in advance for informing me. Jim here.
