Control of the outlet temperature of the steam generator in the sulfur plant
Thread Content
Regarding the sulfur exhaust stream, after the process gas exits the hydrogenation reactor, it enters a steam generator to be cooled. The temperature of the process gas upon exiting the steam generator is around 160 degrees. Is it acceptable if the outlet temperature is reduced to 120 or 130 degrees? There should be no issues if the temperature is lower, right? I appreciate everyone’s active participation. Thank you
The temperature is low; what about the pressure and temperature of the steam? The saturated temperature of steam at 0.4 MPa is 152 degrees.
How much pressurized steam do you produce? Generally speaking, if the steam pressure remains unchanged, such a low temperature of the process gas indicates that there is a leak in the tube bundle.
A lower level has no impact; if there are problems, it indicates that there is an issue with your hydrogenation reactor
It depends on the amount of steam pressure generated; generally, low-pressure steam with a pressure of around 0.35 MPa is produced, at a temperature of about 152°C. The impact on the heat exchanger must be taken into consideration, as there is a limit to the temperature difference between the hot and cold fluids. The smaller the temperature difference, the larger the heat exchange area required.
