In at least one embodiment, the inventive technology relates to in-vessel generation of a material from a solution of interest as part of a processing and/or analysis operation. Preferred embodiments of the in-vessel material generation (e.g., in-vessel solid material generation) include precipitation; in certain embodiments, analysis and/or processing of the solution of interest may include dissolution of the material, perhaps as part of a successive dissolution protocol using solvents of increasing ability to dissolve. Applications include, but are by no means limited to estimation of a coking onset and solution (e.g., oil) fractionating.

What is claimed is: 1. A method comprising the steps of:providing a vessel having a substantially chemically inert stationary phase established therein and having at least one vessel inlet;inputting a precipitant solvent into said vessel through at least one vessel inlet;inputting a solution into said vessel through at least one vessel inlet;intentionally precipitating asphaltenes within said vessel and in the presence of said substantially chemically inert stationary phase, wherein said substantially chemically inert stationary phase is substantially chemically inert relative to said asphaltenes;generating a remnant liquid upon performing said step of intentionally precipitating said asphaltenes;inputting a material dissolving solvent into said vessel through at least one vessel inlet; anddissolving at least a portion of said asphaltenes with said material dissolving solvent to generate a dissolved material solution.
