A continuous process for upgrading a heavy hydrocarbon includes the steps of: obtaining a heavy hydrocarbon; heating the heavy hydrocarbon; contacting the heavy hydrocarbon with a solvent at upgrading conditions so as to produce a first product comprising a mixture of upgraded hydrocarbon and solvent and a second product comprising asphaltene waste and water; continuously feeding the first product and the second product to a first separator; heating the first product; and continuously feeding the first product to a second separator to separate the upgraded hydrocarbon from the solvent. A system is also provided.

Process and system improvement for improving and recuperating waste, heavy and extra heavy hydrocarbons

A process for upgrading a heavy hydrocarbon includes the steps of obtaining a heavy hydrocarbon; contacting the heavy hydrocarbon with a solvent at upgrading conditions so as to produce a first product comprising a mixture of upgraded hydrocarbon and solvent and a second product comprising asphaltene waste, water and solvent; and feeding the first product to a separator to separate the upgraded hydrocarbon from the solvent. A system is also provided.

Process for improving and recuperating waste, heavy and extra heavy hydrocarbons

A process for preparing a bimodal emulsion of viscous hydrocarbon in water includes providing a stream of water at ambient temperature; providing a liquid additive that tends to gel when mixed with water at temperatures less than a gelling temperature T; heating the stream to provide a heated stream at a temperature Twhich is greater than ambient temperature and less than the gelling temperature T; feeding the heated stream to a mixer having a mixer inlet so as to impart energy to the heated stream; adding the liquid additive to the heated stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive to provide a substantially homogeneous solution of additive in water. The solution is then divided and used to make two different droplet sized emulsions which are mixed to form the bimodal emulsion.

Manufacture of stable bimodal emulsions using dynamic mixing

A process for preparing a hydrocarbon in water emulsion, comprising the steps of providing a liquid additive that tends to gel when mixed with water at temperatures less than a gelling temperature T ; providing a stream of water at a temperature T less than the gelling temperature T ; feeding said stream to a mixer having a mixer inlet so as to impart energy to the stream; adding the liquid additive to the stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive so as to provide a substantially homogeneous solution of the liquid additive in the water; and mixing the solution with a hydrocarbon in a mixer so as to form a hydrocarbon-in-water emulsion. In further accordance with the invention, different emulsions can be formed and combined so as to provide a combined emulsion having desired properties.
