Abstract
Description
Technical field
The present invention relates to a kind of solar energy that utilizes and join the crude oil transportation system of associating heat pump, belong to the heating crude oil technical field as clean energy resource.
Background technique
The condensation point of crude oil of China is generally higher, and viscosity is big, and the normal temperature current downflow is poor, so after crude oil is pooled to the ground metering station from each individual well, often need be with heating crude oil to 50 ℃～60 ℃, to keep its good flowability in the transport process at each station after being sent to again.Thereby heating crude oil need consume the great amount of conventional energy: use coal combustion, oil, rock gas and electrical heating method to realize heating crude oil.But not only Crude Oil Transportation system energy utilization rate is on the low side for this mode of heating, and energy matter usability is very poor, has caused the consumption and the waste of fossil energy, but also has caused the serious environmental pollution problem.
For addressing the above problem, seeking the conventional heating crude oil mode of movement of mode of heating replacement energy-conservation, cleaning becomes hot research in recent years.Publication number be CN1654879 patent disclosure a kind of solar energy indirect heating transporting system that comprises solar heat collector, little hot water storage tank, Intermediate Heat Exchanger and oven, utilize solar energy partly to substitute conventional energy resource heating conveying crude oil, saved energy consumption, play the minimizing environmental pollution, the effect of environment purification.
