摘要
Closed system (2) to obtain marketable petroleum coke fragments of solidified petroleum coke in a coke drum unit (4, 8), including a coke drum unit (4, 8) to contain solidified petroleum coke ; a coke crushing unit (6, 10) for crushing petroleum coke to marketable petroleum coke fragments; a closed suspension tube (12) that directs petroleum coke suspension to a closed suspension well (14); a closed suspension well (14); a unit of dehydration deposits (18, 20) with dehydration deposits (18, 20) configured to receive the coke suspension of oil from the closed suspension well (14), to collect marketable petroleum coke fragments, a deposit water sedimentation (28); a clean water tank (29) configured to receive purified water from an upper part of the water sedimentation tank (28); and an extraction unit (52) configured to remove marketable petroleum coke fragments from the dehydration tank unit (18, 20); where the dehydration tanks (18, 20) are configured to act as a filter that drains the drained water purged from a lower area of the dehydration tanks (18, 20) as filtered water and petroleum coke fines; characterized in that a closed drain water well (24), separated from the closed suspension well (14), is configured to receive filtered water and petroleum coke fines from the dehydration tank unit (18, 20) by a line (22) that connects the dehydration tank unit (18, 20) with the closed drain water well (24); and because the water sedimentation tank (28) is configured to receive the filtered water and the petroleum coke fines coming from the closed drainage water well (24) and separate the petroleum coke fines from the water collecting the fines from petroleum coke at the bottom of the water sedimentation tank (28), and conduct the petroleum coke fines to the closed suspension well (14) where they are mixed with the petroleum coke suspension; where the dehydration tanks (18, 20) include an upper cylindrical section and a lower conical section, the upper cylindrical section and the upper part of the lower conical section being provided with filter channels, especially internal sieves, and / or provided with the lower part of the lower conical section of a drilling configuration to draw accumulated water from the dehydration tanks (18, 20), and where tubes have been placed connecting the filter channels and / or the drilling configuration to the line (22 ) leading to the closed drain water well (24).
