DEVICE FOR REGENERATION OF FUMES IN RESERVOIR WITH HIGHLY VOLATILE LIQUIDS Russian patent published in 2000 - IPC

FIELD: petroleum refining and chemical industries. SUBSTANCE: device has housing vertically installed on exhaust pipeline with attachment of gas permeable capillary porous material fitted on by upper edge. Attachment is made in form of vertical cylindrical shell placed inside housing to form ring clearance and stopped by container from lower end face. Container is partially filled with absorbent covering lower edge of attachment which is made multiple-layer and assembled of alternating two layers. Material of one layer has capillary porous structure and material of other layer, large-pore structure. Inner and outer layers of attachment are made of large-pore structure material, and entire attachment is clamped between two support concentric cylindrical metal gauzes. Device has improved performance characteristics at regeneration of fumes of highly volatile liquids. EFFECT: reduced losses of highly volatile liquids and contamination of atmosphere. 2 dwg
