Basically, hydrocarbons are flammable but the levels in which they burn can be figured and calculated and thus it may be controlled as well with the appropriate ratio of it mixed in with air. With this in mind, combustion may be stopped depending on the environment it is in. This process may be called as deflagration which means burning down the flames.
A lot of industries needs to have more control and safety when it comes to managing hazardous liquids and flammable materials. Because of the Clean Air Act of the USA, industries are required to minimize the combustions of gasses in order to maintain the safety of both the environment and the people. That is why detonation arrestor is invented.
It was on 1990 when Nicholas Roussakis invented this Flame Arrester or Arrestor. The initial mechanism for this was to burn down the combustion or ignition within a pipe or tank so that it would not go through anymore towards the source of the gas. This prevents any explosion from occurring, although this one is different with the detonator and is actually a innovation from the initial invention.
The detonation actually is innovated in order to withstand very high pressure rates up to one thousand five hundred psi or ten MPa. It also can handle supersonic speed that travel through the pipes up to two thousand five hundred meters per second. So basically, this is placed between two pipes or sources in order to make it as a demarcation between the two in case of ignition but still lets the gas flow through.
This is a passive device so there are no moving parts inside it and should be working once it is installed. Inside it is composed of many layers of metallic ribbons that has crimped corrugations. This allows the travel of gas to flow but combustion to stop at certain levels.
There are studies on the limit of these hydrocarbons up until which point of the ratio between them and the air composition for them to burn and stop. This is called their Lower Explosive and Upper Explosive Limits or LEL and UEL. The tests conducted would help determine up to which point to the metal ribbons should be compressed in order to work.
The LEL is the first start of the hydrocarbon and air composition where it starts small and increase and up to which percentage it would begin burning, while the UEL is the percentage to which it stops after increasing it further. So the air and the hydrocarbon percentage would be recorded appropriately depending on which point it burns and stops. With these calculations, the arrestor is made according to it.
For example, Methane gas is shown to have five percent of its Lower Explosive Limit. Therefore, at five percent methane as to ninety five percent air, it would start to combust already. While at fifteen percent methane composition with eighty five percent of the air, it would then start to stop burning. Although there are some gasses that require no oxygen at all for them to combust.
These gases are highly dangerous when they are not controlled and contained appropriately and if there is no backup or safety precautions in cases of incidents. That is why this was invented to protect the people inside who are working as well as the environment. This is called a vapor control system for most of these industries.
