U35 Upgrade

The purpose of the intervention is to finalize the installation of the gas dehydration skid (Package 30-UZ-3502) definitive through the revamping of the temporary Unit 30-UZ-3502 whose function is to implement Unit 35 to allow proper drying of the regeneration gas coming from the Molecular Sieve Unit (Package 30-UZ-3501). 

The proposed unit treats the gas through absorbers in order to remove the water from the gas leaving Unit 35 regeneration cycle, to reach the sales specification. 

Therefore, Package 30-UZ-3502 involves the removal of water from the gas used to regenerate the adsorption tower. 

The dehydrated gas will be sent to the fuel gas line inside the system (Unit 60) for the gas to be injected into the SNAM network in compliance with appropriate sales specifications (water dew point of -32°C at 2,1 barg).
