Abstract

PURPOSE: To prevent the deterioration by heat and coking and generate diluted steam efficiently, by covering the heat transfer surfaces with oil films in a specific heat exchanger provided after a quick cooling heat exchanger, and carrying out the heat exchange.
CONSTITUTION: A high-temperature gas 23 after a decomposition furnace is once cooled in a quick cooling heat exchanger 11 to 400W500°C and recovered as high-pressure steam 19 at 80W120kg/cm2. The decomposition gas 23 after the quick cooling heat exchanger 11 is passed through heat transfer tubes 3 in an oil quencher 13 to carry out the heat exchange through the heat transfer tube walls and oil film flowing down thereon with water 25 introduced from a supply water port 4 to the shell side of the heat exchanger 11 to become a diluting steam 20 at 8W10kg/cm2, which is discharged from an outlet 5. The decomposition gas after the oil quencher 13 is cooled in an oil fitting 14 and fed to the decomposition tower.
