Post by md.jahangiralam » Sun Jan 21, 2018 10:00 am

I am experiencing Cold Box Perlite Unloading and Refilling to facilitate leak detection and repairing of piping leakage inside of cold box.

Seeking experience sharing from the group members with similar job experience.

Thanks

@ahsansarfraz, Cold Box manufacturer is Costain Engineering, England. And also aluminium was welding carried out.

@PKS1964, Perlite unloading and refilling was carried out by ourselves, but welding was carried out by external welder of Fives Cryogene, France. Regarding procedure perlite unloading and refilling is very usual only process isolation and purging/handover is important which will vary depending on process configuration. Perlite condition was good after being used for 25 years. Only partial make up is provided.
