Is it necessary to add antistatic agents to gasoline and diesel?
Thread Content
Let's discuss whether it is necessary to add electrostatic agents to gasoline and diesel? It is said that Sinopec requires all refineries to add fuel, but PetroChina does not require it?
It is very necessary ~ Sinopec requires it because most of their products are mid-stream and downstream petroleum products, which are more dangerous. Most of PetroChina’s products are upstream products after crude oil, and there are no requirements for upstream
I cannot agree with your explanation. Regardless of whether it is mid-range oil products or upstream products, what you are raising now is the question of whether gasoline and diesel should be added with additives.
I think it is not necessary. Many anti-static measures have been taken into account in the storage and transportation design, such as controlling flow rate, adding anti-static tubes, anti-static measures for equipment, etc. If the anti-static agent has a great impact on the quality of the oil, other anti-static measures can be taken as much as possible. There is also a cost calculation issue.
I agree with what you said. It is actually not necessary to add antistatic agents in the factory, but it is said that the requirement to add antistatic agents is to prevent safety problems during use.
I'm from Sinopec, and we all added it.
Could you please tell me about your dosing process and operating procedures on the 6th floor?
The addition of antistatic agents is mainly required to ensure safety during the transportation and use of gasoline and diesel, not because of upstream and downstream product reasons.
It is better to add it, because the current technology is hydrogenation of gasoline and diesel, and the conductivity of refined gasoline and diesel itself is low. For safety reasons, I think it is necessary to increase the conductivity!
I don’t think it’s necessary, so I’ve taken anti-static measures into account in the storage and transportation design.
The national product standard has requirements for the conductivity of factory products, and it will not pass if it is not added. I'll add it here. Aviation kerosene is also added. My dosing process and operating procedures: 1. Add T1502, 1 to 2ppm. 2. It was originally added when the device was taken out, but the effect was not good and the consumption was large. The reason was attenuation. Now add it in the tank area, that is, synchronize the blending. 3. After dilution in the container, it can be driven in by a diaphragm pump or by nitrogen pressure. Turn the blending pump cycle back on. 4. The tank is equipped with plum blossom nozzles and hydraulic stirring jet nozzles. 5. The pipeline is equipped with a static mixer.
It’s better to add insurance than not, but it mainly depends on the cost.
Does it have the function of preventing electrochemical corrosion during use? ?
