METHODS OF REMOVING CONTAMINANTS FROM A PLURALITY OF PRODUCT STREAMS Russian patent published in 2020 - IPC C10G65/16 B01D3/32 

FIELD: production technology.

SUBSTANCE: invention relates to a method of separating product streams from different reaction zones, comprising feeding at least portion (32, 46, 112a, 112b) of a first liquid product stream (26) from a first reaction zone (6) to a first separation zone (100); feeding at least second portion (76, 122, 122a, 122b) of second product liquid stream (68) from second reaction zone (8) to second separation zone (102), wherein second reaction zone (8) differs from first reaction zone (6); separating portion (32, 46, 112a, 112b) of first product liquid product stream (26) in first separation zone (100) into upper product stream (118) and bottom product stream (116); separating portion (76, 122, 122a, 122b) of second product liquid stream (68) in second separation zone (102) into upper product stream (134) and bottom product stream (126); feeding upper product stream (134) from second separation zone (102) and upper product stream (118) from first separation zone (100) to upper product combined receiver (110); feeding reflux stream (140) for at least second separation zone (102) from combined receiver (110) of upper product; and supply of reflux stream (120) from second separation zone (102) to first separation zone (100).

EFFECT: technical result is combination of stripping sections of two different hydroprocessing units provides for efficient and effective separation of products.
