Aside from whether the "refining" at the pithead could address the
sulphur, arsenic etc problems and just concentrating on the water
aspect. It's a fairly simple sum, if the bulk density is sufficient
that the cost per tonne of transport doesn't change between the dry
product and the wet product then you can afford to spend the same
amount per tonne in drying. In practice people won't change unless
there's a fair profit margin in making the change. High temperature
drying is likely to be expensive in the absence of waste heat.
