In some embodiments of method 600-b, passing the hydrocarbon aerosol through the bulk liquid hydrocarbon further includes passing the hydrocarbon aerosol through a mesh of solid material disposed within the bulk liquid hydrocarbon. In some embodiments, passing the hydrocarbon aerosol through the bulk liquid hydrocarbon may further include passing the hydrocarbon aerosol through the bulk liquid hydrocarbon with respect to multiple baffles disposed within the bulk liquid hydrocarbon. Passing the hydrocarbon aerosol through the bulk liquid hydrocarbon may further include passing the hydrocarbon aerosol through the bulk liquid hydrocarbon through a mesh of solid material disposed around the multiple baffles disposed within the bulk liquid hydrocarbon.
Some embodiments of method 600-b include removing water or other liquids with respect to the remainder of the bulk liquid hydrocarbon. In some embodiments, the water may be immiscible with the remainder of the bulk liquid hydrocarbon. In some embodiments, the water may be immiscible with and gravimetrically separable from the remainder of bulk liquid hydrocarbon.
