摘要:
A multipurpose chemical additives (MPC) is disclosed to mitigate fouling in hydrocarbon refinery processes, such as in a heat exchanger. A method for reducing fouling of a hydrocarbon is also disclosed that includes (i) providing a crude hydrocarbon for a refining process; and (ii) adding an additive to the crude hydrocarbon.
摘要:
Methods and systems for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process and adding an antifouling agent containing a polymer base unit and a polyamine group to the crude hydrocarbon are provided. The antifouling agent can be obtained by converting a vinyl terminated polymer, such as polypropylene or poly(ethylene-co-propylene), to a terminal acyl containing functional group, followed by reacting the terminal acyl containing functional group with a polyamine compound.

摘要:
The present invention pertains to a pervaporation membrane process for the separation of high octane fuel components from a gasoline feed stream comprising feeding a mixed phase vapor-liquid feed to a cyclone separation means to separate the liquid from the vapor, then sending the saturated vapor to the membrane, thereby extending the useful life of the membrane.
