APPARATUS FOR REMOVAL OF HYDRATEPARAFFIN SEDIMENTS Russian patent published in 1996 - IPC

FIELD: gas and oil producing industry, apparatuses for removal of hydrateparaffin formations in wells, paraffin and resin sediments in pipelines transporting oil and gas and also for dissolving of structural sediments of synthetic resins, silicates an etc. SUBSTANCE: apparatus has container mounted on communication member with surface lifting equipment and filled with reactant. Container body is made of material engaged in thermal chemical reaction with reactant. Lower part of body has hole covered by plug of light-melting material. Inside container there is filter made of metal neutral in respect to reactant and there are detachable tips with different diameters of holes - from 0.5 to 3.0 mm. Usage of apparatus increases degree of purification due to adjustment of hot gasses output duration and temperature of exothermal reaction. EFFECT: increased degree of purification. 2 cl, 1 dwg
