Which difficult problems in storage tanks need to be known and mastered?

For storage tanks, as long as you carefully read the relevant articles on the website, you will not feel unfamiliar with them. So, since there are already some foundations and preparations ahead, it's better to seize the opportunity and continue building on the existing foundation in order to enhance everyone's understanding of storage tanks and achieve satisfactory learning outcomes.

How to solve the pumping problem for large storage tanks?

Large storage tanks have large inlet and outlet pipeline diameters, typically reaching around 900 millimeters. So, during its pumping process, it is easy to encounter problems such as incomplete pumping. Therefore, if you want to solve this problem, you can set up a low position small-diameter bottom pumping oil pipeline on the storage tank, so that the oil can be pumped clean.

2. Does the storage tank need to be filled with nitrogen for maintenance?

For this, it depends on the specific type of storage tank. If it is sealed with liquid ammonia or flammable and explosive, nitrogen protection is required. However, if it is sulfuric acid, hydrochloric acid, etc., then nitrogen protection is not required.

Why can't the storage tank be filled with liquid from the outlet?

The main reason for this conclusion is that if this operation is carried out, if the amount of liquid gradually increases, there will be some problems when the pressure increases, such as increased difficulty and inversion phenomenon. In addition, during the process of falling, liquids also generate electrostatic friction, which is why this conclusion is reached.

How should the filling coefficient of the storage tank be determined?

The filling coefficient of storage tanks is mainly for liquefied gases. As for its purpose, it is to ensure that a certain amount of gas phase safety space can be retained during the heating process of liquefied gas, so as to prevent gas volume expansion, which can double the pressure of the storage tank and cause various problems, dangers, and accidents. How to determine it is to first determine the safety factor of the storage tank, and then determine the filling factor.
