Petrochemicals And Energy

• Inert protection and purge

Storage tank and pipeline protection: cover flammable liquid with nitrogen to prevent explosion.

Reactor purge: Before chemical production, nitrogen is used to replace oxygen to avoid accidental combustion.

LNG Liquefied natural gas: nitrogen is used for pre-cooling equipment and pipeline drying.

• Oil refining and cracking

Catalytic cracking: nitrogen as a catalyst transport medium.

hydrogen desulfurization: After the reaction, the system uses nitrogen to purge the residual hydrogen.
