Elemental sulfur clogs the heat exchanger
Thread Content
Dear colleagues, have you ever encountered a situation where steam contains elemental sulfur, and after passing through a graphite heat exchanger, this elemental sulfur blocks the channels of the heat exchanger? What are the good solutions for dealing with this issue? Considerations from both equipment and technical perspectives would be appreciated. Thank you!
Options such as separating elemental sulfur from the steam or raising the temperature of the heat exchanger above the sulfur crystallization temperature should be considered
Secondary steam always cools down, and it’s difficult to keep it at its melting point. Is there any way to remove sulfur?
What kind of process is it? I would appreciate guidance from those who know more. Thank you.
Could you explain the specific operating conditions of graphite heat exchangers? so as to provide targeted suggestions.
The secondary steam contains sulfur vapor; after condensation and heat exchange, elemental sulfur precipitates, causing blockages in the graphite block channels
Regular steam purging of the tube side (medium side) should be carried out, using a steam pressure of 0.4 MPa and a temperature of 151 degrees. At this temperature, the viscosity of the molten sulfur film is relatively low, making it easier to remove.
