Abstract
A VACUUM VESSEL FOR CONTINUOUS OR SEMI-CONTINUOUS TREATMENT OF OIL IN CONNECTION WITH DEODORIZATION COMPRISES SPACES (12, 121 , 122) THROUGH WHICH OIL TO BE TREATED IS BROUGHT TO PASS AND MEANS TO HEAT OR COOL THE OIL IN THE FORM OF U-TUBES. THERE ARE PERFORATED PIPES (26) ARRANGED AT THE BOTTOM OF SAID SPACES TO LEAD STRIPPING GAS INTO SAID OIL THE VESSEL HAS A CONNECTION TO A VACUUM SOURCE (7) . THE SPACES IN THE VESSEL ARE ARRANGED SUCH THAT THE OIL TO BE TREATED IN THE VESSEL FLOWS THROUGH THE SAME BY GRAVITY. THE HEATING OR COOLING MEDIUM PASSING THE U-TUBES IS ARRANGED TO BE PUMPED THERETHROUGH. THE U-TUBES FOR HEATING OR COOLING MEDIUM ARE ARRANGED IN SUCH A WAY IN SAID SPACES THAT THE FLOW OF OIL IS COUNTER-CURRENT TO THE FLOW OF HEATING OR COOLING MEDIUM ALL THROUGH THE VESSEL AND A NUMBER OF U-TUBES ARE ARRANGED IN GROUPS (13), PARALLEL AND IN ROWS ABOVE EACH OTHER IN SAID SPACES
