Cat Feed Hydrotreater make-up compressor automatically shut down due to thermal overload. The shutdown caused excess acid gas loading at the refinery Sulfur Recovery Unit (SRU) which lead to increased Sulfur Dioxide emission from the SRU Thermal Oxidizer (THOX)
K7702 was restarted and SRU and CFHT operations were stabilized and efforts were made to reduce SRU THOX Sulfur Dioxide concentrations
