Hi,

 

For Refinery Fuel Gas Treatment Unit & Amine Regeneration Unit, how to determine/evaluate or know Amine Total System Volume, .as we know liquid side of Amine Unit is almost closed with only makeup amine added to account for losses etc.

 

How do we determine Amine System for two different systems now.

 

Regards,

CHEMSTRONG

Makeup Amine Flow for ARU is Continuous or in batches here? for Amine Regeneration Unit ARU ?? 

 

Hi,

 

As far as i know the makeup as Fresh Amine is continuously (but with adjustable flow rate) added along the recirculating line between Amine (solvent) storage tank and Amine Filtration Package.

Thanks Sir,

 

 

What is the use of Amine Filtration Package ? 

 

Corrosion Inhibitor used for Amine Regeneration Unit (ARU) is based on Total Amine System Volume right ?  CI is added to avoid corrosion caused by Amine Salts right ??

 

CI Dosage will also depend upon Amine Recirculation Rate also ?

 

 

 

Thanks

 

Best Regards,

Hi,

 

Continuous Amine filtration in the relevant Package eliminates all solid scale, dissolved hydrocarbons and contaminants which can promote corrosion and foaming problems in the Gas Treating Unit.

 

Corrosion inhibitor may or may not be required based on a corrosion study; then if it's required the dosage rate will be specified upon the Amine type and Amine recirculation rate, concentration,...

Dear Fallah Sir,

 

Thanks for your reply and guidance.

 

I wanted to  know when we inject Corrosion Inhibitor in Amine Systems like Amine Regeneration System (ARU) , FGTU( Fuel Gas Treating Unit ),  what is the basis of injection: It will be always Amine System Total Volume ?  What is generally this value( Amine System Total Volume )  for Refinery ARU ? 

 

Suppose Dosage rate is X ppm based on Amine System Volume . Why they take always Amine System Volume and not Amine System Recirculation Rate here?

 

Also these systems are mostly Water based right ?

 

Please advice.

Dear Fallah Sir,

 

Amine System Volume: How can we estimate this value ?
