How to operate and maintain a sulfur unit in thermal standby mode
Thread Content
I would like to ask the teachers: One of our two sulfur treatment units is in operation, while the other is to be kept in hot standby mode, ready to receive acidic gas. How can the hot standby state be established and maintained? What are the things to keep in mind? Thank you!
Maintain the temperature with fuel gas to ensure that the conditions for introducing acidic gas are met at any time
Should the exhaust hydrogenation process and sulfur production be connected or separated?
Is the exhaust gas from the SCOT process? Pre-sulfidation is required for the first start-up of the hydrogenation catalyst or when a new catalyst is installed; hydrogenation and sulfur production are carried out separately. Drive the vehicle normally, just as with combustion at fuel gas and air equivalence or at 95–99% chemical equivalence, and maintain the temperature of all equipment at operating levels. For sulfur recovery, it is necessary to keep the temperature of each reactor at or above the sulfur dew point temperature
What is the dew point temperature of sulfur, approximately?
