Abstract: A process of mass transfer is described which utilizes latent heat transfer with little or sensible heat transfer. In a preferred process microbubbles are used under certain conditions of contact with a liquid phase to ensure highly effective mass transfer between a gaseous and liquid phase with significantly less than expected or little or no sensible heat transfer. The present invention in part provides a means by which the known state of a cold liquid of varying depths can be changed using a hot gas injected via a micro bubble inducing internal mixing without allowing the resultant mixture to reach equilibrium thereby ensuring the transfer process becomes continuous. Thus a process is described wherein at least one gaseous phase is contacted with at least one liquid phase such that the heat ratio of the system (AA) is maintained at an a value of greater than 0.5, and the mass transfer is effected by passing a gaseous phase comprising microbubbles through a liquid phase of thickness no more than 10 cm.

Abstract: A delayed coking process in which shot coke and thermally cracked coker products are produced from a sponge coke- and/or transition coke-forming resid feed comprising sponge coke asphaltenes by mixing heteroatom (preferably nitrogen) containing asphaltenes from a shot coke-forming resid with a heated sponge coke-forming resid to form shot coke directing asphaltene aggregates in the resid. The mixture of resid with the added asphaltene is held at an elevated temperature to allow co-aggregates of sponge coke and shot coke asphaltenes to form which, upon delayed coking promote the production of a free-flowing shot coke product.
