Operation Safety Is Important for Chemical Storage Tanks

It is important to master the correct operation mode of chemical storage tanks,  which is the main measure to ensure its safe operation. Because even if the chemical storage tank design meets all of the requirements and the installation and manufacture don’t have any problems, but if the operating process is not properly, it will also lead to the occurrence of chemical accidents. Then what are needed to pay attention during the operation of chemical storage tanks?

Ensure the operation stabilization of chemical storage tanks

Because in the operation process, the pressure change of chemical storage tanks is frequent, the whole wave is very large, what’s more, the anti fatigue performance is not good, we should try our best to ensure the stability of the pressure in the operation of chemical storage tanks, and to avoid the large change of tank shell temperature. For the case of two chemical storage tanks, it is important to avoid the overload and overpressure. For reaction tank, the control of feed is very important, in order to avoid the runaway reaction, leading to the phenomenon of overpressure of chemical storage tank. It should be strictly tested, and no thermal dilation and overpressure is allowed.

When close the fuel tank of chemical storage tank urgently, corresponding emergency measures should be taken so as to avoid the abnormal phenomenon. Under agency rules, the problems that chemical storage tanks often appeared include temperature, working pressure, tank wall temperature, change of medium, etc. If the emergency measures can not control effectively, the chemical storage tank will be caused deformation, cracks and uplift, etc, more serious is the occurrence of leakage phenomenon, or the fastener and safety accessories appear damage and failure, ultimately leaded to the safe operation can not be guaranteed.

Storage requirements of chemical storage tanks

Actually, there are many aspects requiring attention when installing the chemical storage tank. If it is improperly installed, the chemical storage tank will suffer from serious leakage and so on, so we should have a total understanding of the tank before installation.

• Risk analysis is essential for the storage site of chemical storage tanks, unnecessary influence on the surrounding residential areas, enterprises, and factories are not allowed. Risk and safety distance must be guaranteed that have no impact on the surrounding environment, or influence is within the standard range.
• Pay attention to the placement of chemical storage tank, especially focus on the local climate conditions, duration time of thunderstorm season, geological conditions, and so on, whether they are fully in accordance with the installation conditions or not, and whether there has an earthquake or other geological disaster.
• Safety must be the most important factor in the site selection of chemical storage tanks, because safety storage site is the guarantee to use chemical storage tank better.

Effective maintenance for chemical storage tanks

In order to guarantee the production safety of enterprise, the operation safety of chemical storage tank itself, and promote the service life and production efficiency effectively, proper inspection and maintenance should be carried out, which prevent the chemical storage tanks from effecting the whole production because of the mechanical breakdown, or causing damage to the operator because of the mechanical accident.

Under normal circumstances, the maintenance cycle of chemical storage tanks can be divided into the following points:

• Medium maintenance is 60-120 days, overhaul is 12 months, medium maintenance includes drop, leakage, cleaning, the maintenance and replacement for the change of liquid surface, as well as the dredging and cleaning of inlet, outlet, and blow-down valve.
• Overhaul major includes the internal parts of the chemical storage tank. When it is found that there is a crack in the inner part of chemical storage tank, or have serious corrosion and so on, it is required to carry out relevant inspection or replace the tube section. When the repair, it is best to use polymer composite materials to repair, can also repair and replace the tube section in accordance with the internal and external requirements of the maintenance. After the end of test, the leakage test and hydraulic pressure are necessary.
