State of the art technology for safe deposit removal
Background
The fast, efficient and safe cleaning of heat exchangers during shutdown is a primary requirement of petrochemical industry to meet tight timeline of shutdown and start-up. The release of hazardous compounds (e.g. H2S), combustible gases (LEL) or the development of pyrophoric iron sulphide (FeS) should be avoided as far as possible.
Objectives
- No hazardous or combustible gases (e.g. H2S LEL, etc.) after cleaning and decontamination
- Removal and elimination of pyrophoric iron sulphide (FeS)
- Successful cleaning of the outer tube bundle surface and inner surface of the shell
- Less time for total cleaning
- No mechanical cleaning requirement
