DISTILLATION COLUMN REFLUX CONDENSER Russian patent published in 2012 - IPC B01D3/04 B01D3/32 

FIELD: process engineering.

SUBSTANCE: invention relates to heat-and-mass exchangers incorporated with distillation columns and may be used in chemical, oil processing and other industries. Reflux condenser consists of housing with unions, contact tubes made from fluted sheets. Round-section inclined corrugation of said sheets features radius of cross-section equal to that of contact tubes. The latter are provided with helical spirals and shaped beads arranged on outer side of concaved inclined flutes over entire length of sheets. Besides they include plugged fluid distribution branch pipes and heat carrier discharge branch pipes arranged in sequential rows along contact tube axis perpendicular to sheet surfaces. Aforesaid housing incorporates condensate collection top and bottom chambers communicated with flutes arranged at bottom under faces of contact tubes between heat carrier discharge branch pipes and above gas branch pipes at top. Note here that top faces of sheets defining vapor passages on contact tube are located above condensate collection column.

EFFECT: higher column efficiency.
