VISCOUS HYDROCARBONS UNLOADING METHOD Russian patent published in 2003 - IPC

FIELD: pipeline transport. SUBSTANCE: invention relates to transportation of viscous heavy hydrocarbons along main pipelines and unloading them from different containers, pumping them within the limits of storage and in process of technological cycles. According to proposed method, raw hydrocarbon material is initially subjected to action of acoustic loads and space over upper level of hydrocarbon surface is vacuumized to extract gases from hydrocarbons and increase fluidity of product passing through free branch pipe. Then hydrocarbons are subjected to action of gauge pressure and acoustic loads owing to transmission of acoustic wave front to mass of hydrocarbons at choosing of acoustic waves from range of 25-30 kHz with gradually decreasing the frequency to 500 - 1000 Hz and decreasing applied pressure within the limits of 1.50 to 1.05 atm. Remaining raw material is removed using flat screen radiators and by action of acoustic waves on sediments which provides homological disintegration of links between molecules of hydrocarbons, disintegration of globules and blobs and transformation of mass of hydrocarbon material into freely flowing quasicolloidal phase form. EFFECT: facilitated draining, reduced time taken by said cycle. 3 dwg
