Product Name: Ferrous Sulfide Vapor Phase Passivation Cleaning Agent

Technical Specifications:

Performance and Application: This product is a colorless to light yellow transparent liquid. 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 to personnel and the environment, ensuring maintenance proceeds smoothly.

Usage Instructions: This product is a concentrate. Used as a vapor phase passivation cleaning agent for ferrous sulfide and a deodorant for foul gases, it can be diluted to a concentration of 10%-15% for passivation cleaning, depending on the specific field equipment and process. After the main process feed is withdrawn during the maintenance phase and the column steaming (steam blowing) stage begins, the cleaning agent is introduced with the steam into all parts of the system to passivate ferrous sulfide and eliminate hydrogen sulfide gas. During passivation cleaning, it is advisable to lower the lower explosion limit (LEL) of various gases.

Packaging, Storage, and Transportation:
(1) This product is packaged in plastic drums: 25 kg/drum, 1 ton/drum, or as required by the customer.
(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, and other incompatible substances. Avoid mixed storage.
(4) The storage area should be equipped with leak emergency handling equipment and suitable containment materials.

Safety Precautions:
(1) This product is slightly corrosive. Avoid inhalation and ingestion. Operators must wear protective goggles, acid-alkali resistant gloves, protective masks, and work caps. If necessary, wear acid-alkali resistant protective clothing.
(2) Do not eat, drink, or smoke while working. Ensure adequate ventilation or local exhaust. Wash hands thoroughly with soap and water after handling.
(3) Prevent impact during handling. Ensure seals are intact and prevent damage to packaging and containers. In case of a leak, dilute and flush with copious amounts of water or cover with sand/soil.
(4) Avoid rough handling during loading and unloading. Ensure containers do not leak, collapse, fall, or become damaged. Prevent the solution from splashing and causing injury during handling.
