Sulfur Recovery Unit

For educational purpose, the better information I have seen is in the GPSA and the other book I have mentionned.

For professional purpose, the claus unit design is a very specific area and I do not think it is possible to design a claus unit if you do not work in a company which has a serous experience in the area.

However, here are some information : heat and material balance is usually done with the software SULSIM. It is dedicated to CLAUS units but it does not give you the sizing of the equipment.

For the sizing of the furnace, the waste heat boiler etc., homemade tools baqsed on empirical data are used. I have seen that the following document: "Design Manual for Amoco sulfur recovery technology" is widely used but I do not have it. Design software like TASC or others are useless because of the complexity of sulphur condensation process (what do you have in the gas phase, S8, S2 ? nobody knows exactly) and the high temperature (around 1200°C and the inlet of the waste heat boiler, no commercial software can handle that).

When it comes to detailed design, experience in claus units is necessary because of the high temperatures, acid gases, liquid sulfur handling etc.

If you some questions do not hesitate.
