What are the downstream impacts from processing sludge following a tank cleaning with a P43®?
A centre mounted P43® wa permanently installed in tank number C3 at the Irish Refining Companies, Whitegate Refinery. The tank remained unmixed for five months. During this period, approximately two cargos per month were transferred in and out of the 150,000 barrel tank for processing in the refinery. Because the tank was unmixed, approximately 3 feet of sludge accumulated in the tank bottom. During the fifth month of operation as the tank was being filled, flow from the tank inlet was diverted to the P43®, thereby utilising the tanker cargo pumps to operate the P43®. In the nine hours during which the tanker was discharging to the tank, the sludge was completed resuspended in the overhead oil. As expected, the crude in the tank was off specification in BS and W and could not be directly processed. To circumvent this problem, crude from the tank with the P43® was blended with crude from another tank, tank C2, in a one-to-one ratio so that composite crude was within specifications for p
