I Preface
For the sulfur content of crude oil processing in the refinery increases and the equipment is in the long-term operation, the amount of ferrous sulfide deposited in the equipment and pipelines increases. Because of the ferrous sulfide’s features of spontaneous combustion, it frequently leads to oil refining equipment damage or accidents in the downtime, which causes the economic loss from hundreds of thousands yuan to millions yuan directly or indirectly.
To prevent the ferrous sulfide spontaneous combustion and ensure the safety of the staff and equipment during the refinery maintenance, our company has developed KX-A ferrous sulfide efficient handling agent based on absorbing the domestic advanced technology. It can better settle all the problems caused by ferrous sulfide spontaneous combustion during the refinery equipment maintenance.

II Acting mechanisms
For the strong activity and complex reactions of ferrous sulfide, the complex agent mixed with a certain percentage of other active ingredients is going to be made into KX-A ferrous sulfide efficient handling agent.

III Product features
1 . It can be react with iron sulfide rapidly.
2 . It is simple to use. Little change on the existing processes of the device is available.
3 . The ferrous sulfide settlement time is short, 10~12 hours generally.
4 . It is safe to deal with raffinate. The system of sour water or oily waste water emission in the factory is available without secondary pollution.

VI Suggestions and services
For the different crude performances and different equipment internal structure in each refinery, agent dosage should be considered when KX-A ferrous sulfide efficient handling agent is settled. Scientific ratio can achieve the best results and reduce the cost. We can provide high quality service based on the factory requirements, including technical advice and on-site technical services.
