Apparatus, processes, and systems for removal of solids from a hydrocarbon stream. The present disclosure utilizes a surfactant to reduce interfacial tension between a hydrocarbon phase and a water (or aqueous) phase to promote solids to be pulled by gravity out of the hydrocarbon phase and into the water phase.

Apparatus and methods to remove solids from hydrocarbon streams

Apparatuses and processes for use in electrostatic filtration are provided. The apparatuses and processes provided herein promote effective and efficient removal of solid matters even in feeds containing a relatively substantial amount of water through the use of a water spreading resistant coating.

Electrofiltration apparatus and process

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.

Functionalized polymers containing polyamine succinimide for antifouling in hydrocarbon refining processes

A method for treating an emulsion of a hydrocarbon is disclosed. The method includes providing an emulsion of a crude hydrocarbon, and adding an additive to the emulsion to obtain a treated hydrocarbon.
