Weighting and cooling underwater oil storage method

Abstract

An underwater oil storage method, using iron ore powder as a weighting material to increase the density of the oil mixture so that it will not be floated, thereby eliminating relative motion and kinetic energy; reducing the temperature of the mixture of oil and iron ore powder as much as possible , increase its viscosity, strive to achieve solidification, slow down the flow rate and the migration rate of sulfide, slow down the leakage rate and the accumulation rate of sulfide, under ideal conditions, the mixture can be as difficult to flow as asphalt; iron ore powder is also An important industrial raw material, while the oil is stored, this weighting material is also properly stored. The method is simple, safe and reliable, and is conducive to realizing the purposes of shortening the transportation (delivery) distance, occupying less land, reducing the impact on the land and water environment, improving safety, reducing energy consumption, and reducing storage costs.

Description

technical field [0001] The invention relates to a method for storing oil under water, and the technology belongs to the field of petrochemical storage and transportation. Oil refers to crude oil, diesel, gasoline, lubricating oil and other liquid petroleum. technical background [0002] The idea of ​​underwater oil storage was proposed as early as 1935, but it was not practically applied until 1967. Its purpose is to shorten the transportation (delivery) distance, reduce the wind and sun, extreme heat and cold, expansion and contraction, and the destruction of its own gravity. function, improve safety, reduce environmental impact, save land, etc. After more than half a century of development, storage tanks with annular chassis, inverted disk-shaped storage tanks, double-cylindrical concrete underwater oil tanks, vertical reinforced concrete underwater storage tanks with anti-wave walls, and ellipsoid-paraboloid-shaped storage tanks have been developed. Underwater concrete ...

AI Technical Summary

Problems solved by technology

However, in the process of oil-water replacement, there will always be a small amount of oil discharged into the surrounding waters with the water, and the environmental pollution caused by accumulation cannot be ignored

[0004] Also, most oil products contain a small amount of sulfur, for example: the world-famous sulfur-free Daqing crude oil still contains 0.1% sulfur in mass fraction, and all the sulfur compounds are gathered together in a container of hundreds of square meters , the corrosion damage to the equipment is also great, and sometimes endangers personal health and life safety

[0005] The most important thing is that the soft container has a large buoyancy, it always tends to break free from the shackles of fixed objects, is in a turbulent state, and there is always the danger of moving, wearing, breaking free and leaking
