Creating plus refining liquid petroleum products uses process energy, generally from the process feedstocks
My thought is that using Geothermal to supply process energy to petrochemical cracking saves about a tenth to a third of all petroenergy Thats kind of like an entire Saudi Arabia worth of oil globally
Giant LNG gas ships are said to be valued at a billion us$
Coal slurry pipes could go brief distances between Washington state coal to active geothermal areas
Any pacific nation or Iceland could efficiently process shipped oil or LNG to create petroproducts
Basically a Pacific nation or iceland uses supereheated fluid possibly metal to grab geothermal energy then uses it at the process plant
Note that Piping schemes that go with durable liquid metal cooled nuclear reactors are much more technically demanding than the milder temperatures that go with hydrocarbon refining yet saving a tenth to a third of the feedstocks likely represents a greater fraction of global energy than all of conventional nuclear during the 20th century
There could be a Green values Gasoline that as it was made with geothermal process energy effectively gave any vehicle a tenth to a third higher equivalent mileage as a gallon of gas is just a gallon of gas rather than a gallon plus a third at the refinery
I support nuclear reactors This is just a cheap way to pick up a bunch of petroleum efficiency-- beanangel, Apr 08 2010 low heat engine http://dirtsimple.com/Best way of converting low heat geothermal hot spots into mechanical energy [travbm, Oct 29 2015] I applaud your new, shorter titles.

Now, tell us where you have hidden the real [beanangel]-- BunsenHoneydew, Apr 10 2010 [+] but save a few volcanos to dump salt into from the great australian lake project.-- FlyingToaster, Apr 10 2010 Why not find a hot geothermal spot of 120 degrees and pump a closed loop to boil something such as acetone to run an engine or run those Tea cup Stirling engines? But geothermal heat for crude oil or coal distillation may be similar to the Kerric Process but you need temperature in excess of 900 F to work for coal. You may need to dig into a magma pocket and tap the heat for coal pyrolysis or for shell and other feed stock. ?-- travbm, Oct 29 2015 random, halfbakery
