Wd02-302 high temperature corrosion inhibitor

 【Product description】

　　In the process of oil refining, when the temperature is higher than 230 ℃, sulfur and naphthenic acid will produce chemical corrosion. Sulfur reacts with Fe to form FES protective film. When naphthenic acid exists in the system, naphthenic acid reacts with iron to form iron naphthenate with surface activity, which can dissolve the FES film and promote the further corrosion of sulfur. Wd02-302 high temperature corrosion inhibitor can modify the metal surface and form a stable and dense chemical film on the metal surface, so as to prevent the corrosion of sulfur and naphthenic acid to the metal and control the corrosion of high temperature sulfur and naphthenic acid.

 【purpose】

　　It is used to inhibit the corrosion of sulfur and naphthenic acid in the middle and lower part of fractionator and bottom tray of oil refining unit.

　【Usage and dosage】

　　1. The recommended dosage is 10 ~ 50 µ g / g. The pre film period is 7 ~ 10 days, and it is added at the rate of 30 ~ 100 µ g / g; Make the corrosion inhibitor form a good anti-corrosion film on the equipment surface, and then gradually reduce the addition amount to normal.

　　2. Injection point: in front of atmospheric heating furnace and atmospheric and vacuum side line, the original agent is added.

　【Packaging and storage】

　　1. 200L iron drum packaging, or packaging according to customer requirements, away from fire sources, and stored in a cool and dry warehouse.

　　2.The shelf life is 24 months.
