    polyethylene fouling

    Thank you, I understand that I could stop it with Co2, but I would also kill the reaction I am running. CO2, in this instance is not an option. Are there any other ideas out there. Thanks

    polyethylene fouling

    I have a reactor that gradually fouls with polyethylene. This is a low density low MW PE. I flush the reactor with a hot isoparaffinic solvent to remove most of the PE. Is there a better way to get it clean? I imagine aromatic or naphthenic solvents would be best, does pressure play a role?

    acid washing alkylate, clay

    We use sulfuric acid to wash alkylate. I need to ensure that all the spent acid is removed. A settler is employed, as well as a collesor. Can I use a clay bed to remove the last bit of acid? What clay would be most suitable? Should ay particular form/shape/size of clay particle be used? Thank you
