Crude oil is an important raw material, from which numerous intermediate and end products are made using complex procedures. In the process, unwanted components need to be removed. These include sulfur, nitrogen and oxygen, salts, trace metals and water. In some of these processes, contaminant gases are released which, depending on their concentration, can cause corrosion damage to critical components.
|Contaminant gases||Sources||Viledon ChemControl pellets|
|Sulfur dioxide (SO₂)||Boilers, Cracking unit regeneration, Treating operations, Flares||CCP 104, CCP 108, CCP 210, CCP 310, CCP 810, CCP 840|
|Nitrogen oxides (NOₓ)||Flares, Boilers||CCP 104, CCP 108, CCP 210, CCP 810|
|Hydrogen sulfide (H₂S)||Sour crudes, Liquid wastes, Pumps, Crude tower, Cracking operations, Rearranging and combining processes, such as reformers and alkylation units, Hydrogeneration||CCP 104, CCP 108, CCP 210, CCP 310, CCP 810, CCP 840|
|Chlorine (Cl₂)||Caustic unit||CCP 310, CCP 510, CCP 610, CCP 840|
Particularly at risk are sensitive areas such as switchgear, control rooms or process control systems. Any build-up of corrosion on the conductive copper and silver components of technical devices threatens process efficiency, increases maintenance costs and results in expensive repairs and unplanned downtime.
Freudenberg Filtration Technologies develops customized solutions to meet the specialist needs of the Petrochemical Industry, including the processing of coal into liquid or gaseous hydrocarbons. Our solutions ensure reliable protection against corrosion resulting from the harmful gases released during the key process steps of petrochemicals.
