Reversion problems with heavy oils, such as heavy fuel oils, are mitigated by introducing an effective amount of an additive that contains both a phase change material and a pour point depressant, even synergistically mitigated.

Phase change materials to address reversion problems in heavy oils

Green demulsifiers useful for demulsifying emulsions of water and crude oil are made by reacting together an alcohol, a multifunctional acid and/or anhydride, and a fatty acid, and optionally a polyol that is polyethylene glycol and/or polypropylene glycol. The green demulsifier has ester bonds between the reactant moieties. These ester bonds can hydrolyze which results in relatively high biodegradation.

Methods of designing green demulsifiers

Dispersants including at least one organic carbonate can keep deposits dispersed within hydrocarbons, where the solids are asphaltenes and derivatives from triazine-based HS scavengers.
