Expert onsite Support during Catalyst loading and Activation
1. Primary Reformer Loading Supervision Using
a) Convectional Sock Loading Method
b) Unidense loading Method
2. HTS/MTS/LTS Loading Recommendation (GRAB Loading) and Supervision of the same.
3. MTS/LTS Catalyst Reduction in presence of Online Hydrogen Analyzer which saves customer time and provides accurate analysis on real time basis
4. Supervision for Ammonia Synthesis Catalyst loading and Activation.
A Clariant Group Company
1. MTS/LTS Catalyst reduction now becomes much smother simpler and faster with use of our In-house Custom made H2 gas analyzer which gives H2 & CO2 analysis on real time basis.
2. Saving on an average up to 6-8 hours of total reduction time. Which means early startup and production after completion of Reduction.

Reforming Catalyst
1. Higher TWT of Primary reformer in a Toyo designed naphtha based Ammonia plant
2. Sulphur poisoning of Primary reformer in a KBR designed Ammonia plant
3. Steam Starvation of Primary Reformer in Hydrogen Refinery in southern India
4. Higher Hydrocarbons passed over to non alkalized catalyst in a hydrogen refinery in east India
5. BFW tubes failure leading to water ingress in Reformer tubes in a hydrogen refinery in central India
6. Higher loaded volume of Secondary reformer leading to high CH4 slip than design
7. Improper mixing of Air and process gas in Secondary reformer leading to higher CH4 slips
