MONOBLOCK UNIT FOR FRACTIONAL SEPARATION OF PETROLEUM PRODUCTS Russian patent published in 1999 - IPC

FIELD: units for fractional separation of petroleum units for production of stabilized petrol, diesel fuel from gas condensate, as well as for reclaiming of glycols used in the processes of preparation of byproduct and natural petroleum gases. SUBSTANCE: unit comprises a vertical fractionating tower, evaporator, furnace with a thermosiphon interconnected in succession and aligned under the fractionating tower. The novelty is in the fact that a dephlegmator is installed on the upper part of the fractionating tower in alignment with it, and the evaporator is furnished with a built-in distribution chamber with slots. EFFECT: accelerated qualitative improvement of the reclaiming of glycols due to the use of sprinkling and blow-off gases, enhanced reliability of process monitoring systems, reduced specific quantity of metal per structure due to connection of several units into a single aggregate system, prevented carrying away of product, eliminated stagnant pockets, enhanced thermal efficiency. 3 dwg
