发明名称 PROCESS FOR THE THERMO-CHEMICAL DE-WAXING OF HYDROCARBON TRANSMISSION CONDUITS
摘要 A process for the thermo-chemical dewaxing of hydrocarbon transmission is described, which comprises, after assessment of the conduit internal effective volume, treating the wax-containing conduit with a water-in-oil emulsion, co-currently to the production flow. The emulsion contains inorganic reactants which generate nitrogen and heat, which fluidize the paraffin deposit which is later driven off by cleaning beds. The percentual of removed paraffin is known by assessing the final internal effective volume.
