Removal of Natural Gas odoriser from the gas 1

[PeterIgg]

Hi all,

The client is using odorised natural gas at 550 - 700 kPa to power a pneumatic style, spring return, piston actuator. However the requirement is to use an activated carbon filter on the vent to, presumably, make the air around the valve tolerable and allow any real leaks to be nasally detectable.

I am aware of activated carbon filters that are made by Norgren, Numatics etc for air breathing sets and the like - anyone aware of any other products or filters that are more suitable to this application?

The fire hazard alone boggles the mind. Why waste fuel gas for something better done by any of a dozen other, cheaper, more efficient methods?

bt, This used to be a very common method of obtaining power in out-of-the-way places on gas gathering and transmission lines.... back in the olden days ... before methane gas emission avoidance became important and the cost of the power gas or solar panels were high. Today, there's not much of an excuse to do it.

Yeah, I can see the attraction, if no other options were available...but I'd still worry about somebody with a lit cigarette wandering by...

Remember those "NO SMOKING WITHIN 50 FT." signs?
They wern't kidding.
