| Abstract: | Ever since the high sulfur crude oil was processed, the corrosion in the medium pressure hydrocracking unit is becoming increasingly serious with eacb passing day. The high pressure heat exchanger tubes have failed, the fractionator furnace feed line reducers became thinner, naphtha column overhead air cooler tubes experienced corrosion failure after desulfurization and H2S in dry gas after desulfurization was over specification. The corrosion and corrosion mechanisms are analyzed. The measures for reduction of risks are described, which provides good information for effective operation management. |
