The dynamic safety management function module of oil tank inlet in the Mobile Big Data Management System for Oil Storage and Transportation developed by Shanghai Qingye Energy Co., Ltd. is a new functional module of oil tank inlet dynamic safety management system developed in accordance with the regulatory documents and guidance on oil storage and transportation safety management issued by multiple national departments, The system function module is widely used in oil storage and transportation safety management systems such as oil crude oil storage and transportation, light oil storage and transportation, natural gas storage and transportation, oil storage and transportation of various refineries, etc.


Dynamic function display of safety management system:

During oil inlet, the oil inlet pump operates and the oil outlet pump stops, the oil inlet shut-off valve is opened and the oil outlet shut-off valve is closed.  The oil enters the oil tank through the pipeline and the oil inlet pump. The liquid level of the oil tank rises slowly. The oil and gas on the liquid level evaporates and compresses and flows into the oil and gas pipeline on the top of the tank through the single call valve to the safety skid mounted TSU on the tank interface. The gas flowmeter on the top of the tank and the gas oxygen analyzer on the top of the tank work to output the gas flow and oxygen content on the top of the tank. If the oxygen content exceeds 5%, an alarm will be given.  At this time, the pressure transmitter on the top of the oil tank is working and outputs the pressure signal.  If the pressure exceeds the limit, the computer will give an alarm. If it exceeds the safety interlock value, it will immediately enter the safety interlock state and open the safety relief valve on the tank top.  The oil and gas enters the oil and gas connecting pipe on the tank top and enters the tank interface for safety skid mounted TSU. At this time, if the pressure on the tank top still rises and reaches the set value, the oil and gas will vent to the atmosphere through the positive pressure exhalation valve to protect the oil tank.
