Asphalt Truck Loading - Vapor Removal

Asphalt Truck Loading - Vapor Removal

Asphalt Truck Loading - Vapor Removal

(OP)
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.

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.
