During the maintenance period, both the tube side and shell side of the exhaust gas heater were inspected, and no blockages were found; the surfaces of the heat exchange tubes were smooth and quite clean. Then why, after operations resumed, couldn’t the inlet temperature of the hydrogenation reactor be raised above 230?℃
Is sulfur production normal? What is the hydrogen content? Is the pH of the quench water acceptable? Has the small solvent load increased? Try increasing the hydrogen gas volume
