This video is an animation of an LPG tank car unloading application. It demonstrates how a reciprocating gas compressor is used for liquefied gas transfer and vapor recovery.
If you were transporting CO2, could you do the transfer without a pump, by just venting gas to reduce the pressure of the recieving tank? This wouldn't recover the tank vapors and imply a loss, but simplify the process.
I live near a big lpg gas plant. Why would big tanker trucks release propane gas into wood near me after getting leaded at the planet? They leave there and go about a mile away and release pressure into the woods ? Are they overloading by accident then have to let someone out.?
If you can visibly see white cloud when they are releasing product is likely because they overloaded. Max weight for a cmv is 80k pounds, unless you have a permit then you can carry more and be legal. Some drivers like to overload to squeeze a bigger profit out of the load. Higher quantity of propane being delivered to the customer means more money or a bigger %% to be paid to the driver.
In a gas dispensing plant, leakages are prevented through a combination of design features, regular maintenance, and safety protocols. Here are some key measures typically employed: Equipment Inspection and Maintenance: Regular inspection and maintenance of all equipment, including valves, pipes, hoses, and connectors, are essential to detect and address any potential leaks promptly. High-Quality Equipment: Installation of high-quality, reliable equipment designed to minimize the risk of leaks is crucial. This includes using durable materials, such as stainless steel, and employing certified components.
Why don't we turn back LPG gas into liquid before we press it into the tank? Because if we can increase the pressure reaching 14bar, the LPG can transform liquid again with boiling point is 38 oC
Hello my dear, can I find an answer from you? For example, I have a tank with a capacity of 1000 liters of gas and it is currently empty of gas. I emptied 40 liters of petroleum gasoline and added an air pressure of approximately 10 bar to that. Does it turn into gas vapor and assuming that I combined it with gas? Is there a good quantity and density of LNG that can be deduced from this? I hope you can help with this
