Natural gas hydrate storage tank truck

Abstract

The invention relates to a natural gas hydrate storage tank transport vehicle, which includes a transport vehicle, a storage tank and a refrigeration system. The storage tank includes an inner tank body and an outer tank body, and a sealed Vacuum heat insulation layer, the top of the inner tank is equipped with an exhaust device to balance the air pressure inside and outside the inner tank, and an agitator is installed along the axial direction of the inner tank to beat and stir the solid particles in the hydrate slurry in the inner tank. An inlet and outlet pipe for loading and unloading hydrate slurry is connected from the outer tank body to the side wall of the inner tank body, and the storage tank is provided with a heat exchange coil connected with a refrigeration system to realize temperature adjustment in the storage tank. In the present invention, a spiral agitator is arranged in the inner tank to beat and stir the solid particles in the hydrate slurry in the inner tank, so as to solve the problem of internal solid particles colliding with each other and coagulating with each other during the transportation of the hydrate slurry. The problem of subsidence due to gravity has realized the economical, safe and efficient transportation of gas hydrate.

Description

technical field [0001] The invention relates to the technical field of natural gas hydrate transportation, in particular to a natural gas hydrate storage tank transport vehicle. Background technique [0002] As we all know, under standard conditions, 1m 3 Natural gas hydrate (NGH) can be stored for 160~180m 3 Natural gas will decompose at normal temperature and pressure, so it is usually stored by low temperature and normal pressure method or high pressure and normal temperature method. Studies have found that natural gas hydrate (NGH) is very stable when stored at -10 to -20°C, and related studies have shown that it can be stored stably for several days in a cold storage at -5 to -10°C without pressure, and only decomposes on the surface , the water produced forms an ice film on the surface. In addition, the thermal conductivity of weather hydrate is very low, which is lower than that of general insulation materials, and it has good self-storage capacity. The hydrate so...

Problems solved by technology

Many oil fields in China have a lot of associated gas. Due to technical limitations, the associated gas is often ignited, which not only wastes resources, but also causes great harm to the environment.
