How much the oxygen content of liquefied natural gas is safe?

To answer this correctly, you need to know what the most dangerous concentration of oxygen with natural gas is. Natural gas can only be ignited in a concentration of 10 to 12% oxygen. Too much it won't ignite (the gaseous form of gas would be too diluted to ignite and sustain a flame), and too little it won't ignite, it needs oxygen. Now if the gas is liquefied, it will not mix well with oxygen, which is still gaseous (it boils at -183F), such that any natural gas boiling off the liquid will, in all likelihood, mix with any gaseous oxygen in that concentration until it becomes an explosive mixture. All natural gas tanks (bulk storage only) are vented to allow a small amount of gas to evaporate off, producing a cooling effect on the tank, and lowering the pressure required to maintain the gas in the liquid form. This venting and cooling also serves to remove any dissolved oxygen from the LNG and vents it to the atmosphere. Bottom line, no oxygen mixed with LNG is safe. Levels must be kept to a minimum to prevent explosions.


Can static electricity ignite natural gas?

Yes, static electricity has the potential to ignite natural gas if a spark is produced. It is important to be cautious when working with natural gas and to follow safety guidelines to prevent any accidents.


What is the color of oxygen in its natural state?

Oxygen is a colorless gas in its natural state.


What is the flash point of natural gas?

The flash point of natural gas is approximately -188 degrees Celsius (-306 degrees Fahrenheit). This is the temperature at which the gas will ignite if exposed to a spark or flame.


What will be observed whena glowing splint is lowered into a gas jar of oxygen?

The glowing splint will ignite into a flame as oxygen supports combustion. This demonstrates that oxygen is a supporter of combustion.

What is the explosive range for natural gas?

The explosive range for natural gas is typically between 5% and 15% gas-to-air mixture. Below 5%, the mixture is too lean to ignite, and above 15%, it is too rich to ignite.


What is the color of oxygen in its natural state?

Oxygen is a colorless gas in its natural state.


What temperature ignites natural gas?

It's not really a question of temprature, it's a question about how high is the activation energy of the combustion of natural gas. this question is however invalid as natural gas is a mixture of hydrocarbons and they all have different activation energys for combustion. Do you mean what temprature would cause natural gas to spontaniously ignite?


Most common natural gas?

The most natural gas COULD be oxygen. But there is a lot of natural gas that we couldn't figure it out.

What spark temperature must the piezo produce to ignite the pilot light on a natural gas fireplace?

The spark temperature produced by a piezo igniter is typically around 1800-2000 degrees Fahrenheit. This temperature is sufficient to ignite the pilot light on a natural gas fireplace, as natural gas requires a high temperature spark to ignite.
