A flame arrestor?

Perhaps one solution could be to vent to the flare.

Wish I had that problem.

Gents, Thanks for the replies.

The problems faced by me against the solutions-
Flame arrestor gets clogged over a period of time. Again how do we maitain the flame arrestor on a 200 feet vent stack of 8" diameter pipe??

The pressure from the compressor seals is too low & hence the same is vented to atmosphere, hence flaring is not an option.

Do we have anything else??

A scrubber maybe?
If your problem is that the gases at the vent stack ignite during a storm, you need to prevent them from getting them.
Depending what they are, you can scrub them prior to venting or maybe enev consider recompressing the gases with a vapour recovery system

Use a water ejector at top of vent to induce the flow of gases and the resultant intermingling of gas and water mitigates against ignition.

you may want to consider CO2 flood. We put a stack of CO2 bottles linked to vent in case of thunderstorm igition. Vent snuffer package.
