Plugging of instruments on Styrene service
Plugging of instruments on Styrene service
(OP)
How to avoid regular plugging of instruments connections (level indicator and pressure gauge) to vessels/systems on liquid Styrene service.
Thanks.
Thanks.





RE: Plugging of instruments on Styrene service
Seems that your problem is due to polymer content in styrene? Or maybe some other impurities?
We run our plant since 20 years and the only problem of plugging had to do with polymerisations. Check the inhibitor level

The essense of the patent is to paint the surfaces with epoxy paint containing the appropriate polymerization inhibitor. Leaching of the inhibitor provides inhibition of polymer in the contacted monomer.
Look it up. I was issued this patent in 1979 and sold it to Dow for a dollar.

One trick learned from experince is to utilise a teflon spray lube on components. At least when the styrene gels or polymerizes, it's easy to disassemble the instruments and components and clean off.
