Our plant has 12 silos at 310m3 and 12 silos at 450m3. They hold high density polyethylene. They do not have explosion panels but do have an air inlet filter housing with a vaccum breaker.

The calculations that I have done estimate the relief area required to be within 12 - 15m2. The problem being that the silos are within a couple of metres of each other (preventing panels on the side of the silos) and there is considerable walkways on the roof (hindering panels on the roof).

Hence I am looking at explosion prevention. I am interested in removing/reducing static rather than inerting due to the variable costs involved. I had come across a company called Valitec who had the technology to suppress electrostatic charge in some applications but have since not been able to contact the company.

Can anyone suggest a solution to my problem, have similar technology or can get me in touch with Valitec?

Thanks,
