Product Name: Ferrous Sulfide Solid Passivation and Deodorization Cleaning Agent
Technical Specifications:
Appearance | White powdery solid |
pH (1% aqueous solution) | 7-9 |
Density (20°C) | ≥1.0g/cm3 |
Performance and Application: This product is a white powdery solid. It is primarily used for the passivation cleaning of ferrous sulfide scale inside petrochemical equipment during shutdowns for maintenance, as well as for hydrogen sulfide deodorization. It prevents ferrous sulfide from spontaneously igniting upon contact with air and mitigates hazards posed by malodorous gases like hydrogen sulfide to personnel and the environment, ensuring maintenance proceeds smoothly.
Usage Instructions: This product is a solid. Used as a passivation cleaning agent for ferrous sulfide and a deodorant for foul gases, it can be pre-diluted to a 10% liquid solution for standby use, depending on the specific field equipment and process. During use, add the diluted liquid product at 5%-10% of the system volume. Increase the dosage if hydrogen sulfide levels within the system are excessive. The optimal effect is achieved approximately 12 hours after the product is fully added.
Packaging, Storage, and Transportation:
(1) This product is packaged in plastic woven bags, 25 kg/bag.
(2) Store this product in a cool, dark, well-ventilated warehouse, away from ignition sources and high temperatures. Storage temperature should not exceed 30°C.
(3) Store separately from flammable materials, combustibles, reducing agents, acids, alkalis, and other incompatible substances. Avoid mixed storage.
