Desulfurization reactor assembly with disposable self-sealing sorbent vessel

A desulfurization reactor assembly having first and second sections, the first section comprising a plenum base including a vapor inflow pathway, a vapor outflow pathway, and a throughflow pathway for passage of heating medium therethrough for heating of vapor in the inflow and outflow pathways;

• the second section comprising two pieces and including a shell within which is seated a disposable self-sealing sorbent vessel, the sorbent vessel containing desulfurization sorbent therein and having a self-sealing normally closed inlet to the vapor inflow pathway and a self-sealing normally closed outlet from the vapor outflow pathway, and the shell and sorbent vessel being spaced apart and creating a heating medium throughflow pathway therebetween;
• all pathways in the second section aligning with the corresponding pathway in the first section when the sections are functionally engaged;
• and the first section incorporating structure therein for causing and maintaining opening of the normally closed pathways in the vessel of the second section whenever the sections are functionally engaged and until disengagement therebetween.
