Hi,

 

Undertaking final year design project to convert Natural Gas to Methanol.

 

I have been tasked with the mercury removal (around 20ppb).

I have extensively researched the removal methods and have concluded on using activated carbon with sulfur impregnation.

 

However, I am stuck with the design phase. I have struggled to get any data on equilibrium and the carrying capacity of the adsorbent material. Where would I be able to source such (isotherm) data?

Is is common for manufacturers to disclose this information to students?

 

Any help/direction would be greatly appreciated

Macdhui,

 

Consider this paper , probably known from you if you have done research on Internet . You may contact the author  ( email ).

 

Good luck!

.... have concluded on using activated carbon with sulfur impregnation.

This adsorbent removes mercury by a chemical reaction with the sulfur, thereby producing mercuric sulfide that remains in the adsorbent bed.

 

There are no isotherms because there is no reversible equilibrium, and this type of adsorbent can therefor not be regenerated for reuse.

 

If you had chosen a regenerative adsorbent of some sort of molsieve type, like UOP's HgSIV, then there would be isotherms, but I don't think manufacturers would share those with students.

Thank you breizh and PingPong, I will chase down this avenue and let you know how I go.
