Pipeline vs Truck
Pipeline vs Truck
(OP)
Hello,
I wonder if someone ever calculate the comparation of power consumption between the thick mud transportation by pipeline and by truck.
If necessary
The capacity is say it 300 m3/hr
height 250 m and length 2000 m. But for dump truck, it should be much longer because dump trucks have to take round way.
The solid content is, say it, 50% and the sg 1.8 to 2.2.
Thank you.
with best regards

RE: Pipeline vs Truck
For produced water, the analysis between trucking and pipeline is done for nearly every project, but the source and sink are geographically fixed. When I think of uses of "mud" I can't imagine that the uses of it would be geographically fixed.

It is in the open pit mining sites. We are used to applying trucks to transport thin mud(o-o not thick-sorry, misters)after dewatering. (Actually they add it with dry solid) for better handling.
First, I guess pipeline is better, because the trucks also carry their own weight. But I am not sure, because the empiric diesel oil consumption is so low, according to the users.
Again, sorry David and all of you. The mud is very thin slurry, beyond the range of centrifugal slurry pumps capability.
Thanks,

Two caveats;
I understand that there may be some pre-separation in a properly designed pipeline which saves some downstream costs.
These decisions are made on the basis of total cost, not just the cost of energy.

"Driving trucks" on a public road to the site may cause no regulatory attention at all (or cause a lot of attention if they attract a politician/homeowner/layer's interest!) while a pipeline or conveyor belt may need months of paperwork and enviro impact studies on beaver dams and mosquito breeding ponds.
It doesn't matter what the real cost is if a politician or activist group can prevent a cheaper solution from being implemented.
RE: Pipeline vs Truck
Where is this operation at, Bangladesh or New York?
What happens if the flow stops on a full pipeline of that mud? Disaster?

If the line stops with mud in it? Turn on the water pump and move the mud out.

I think probably there seems some 'Typo' in Mile's Figure;(2000/1600)=1.25 Mile
and at the most this may be approximated to 1.3 Miles I believe.
Kindly correct this; if I'm not totally mistaken.

RE: Pipeline vs Truck
I imagine, for a truck hauling, the vehicles need to bring the truck bodies, one trip full contained and one trip fully empty for one work cycle. In the pipeline (in this case, paste pumping) the stuff which moves is only the mud. But according to the record, trucking needs more power and fuel!
I wiil not calculate too far until social and political cost. Just wonder.
RE: Pipeline vs Truck
You may want to evaluate using a cost/CYd-mile, which should be easy to obtain from the truck operators and then do a similar resulting unit calculation for a pump & pipeline option.
