Asphalt Truck Loading - Vapor Removal

[nwitt]

Operators loading hot asphalt into tanker trucks are often exposed to a flood of vapors above the truck dome. Most terminals/asphalt plants utilize some type of exhaust system to remove these vapors. Systems can consists of a simple fan to blow the vapors away or piping, a mist eliminator, and pressure blower. I recently installed a system using schedule 10 ss piping, a mist elimination vessel/filter, and a pressure blower. I chose not to use pvc pipe because of concerns with static electricity buildup. In preparing to install another similar system, my boss requested that I try and find additional information to justify not using PVC. Do any of you have any thoughts on this issue? I would like to find some definitive information/guidance one way or the other.
Thanks in advance.

Stainless steel is pretty...

PVC can buildup static electricity and I assume these vapors can be explosive. Just make sure SS pipe is grounded. Probably could use mild steel - but wouldn't last as long.

Dears,
Somehow I am very much concerned about static charge aspect;to be duly taken care off and for this proper bonding/ grounding and even cosideration of soft,good conducting metals/alloys like copper,brass may be worth consediration.
