Safety improvements in a Methanation reactor

Authors


Abstract

A 35-year-old Methanator vessel required replacement due to High Temperature Hydrogen Attack (HTHA). The opportunity was taken to upgrade the over temperature protection system to meet the requirements of IEC 61511. An additional Layer of Protection was added to reduce demand on the High Temperature Trip system. © 2009 American Institute of Chemical Engineers Process Saf Prog 2009
