IOCL keeps catalyst regeneration tender technically demanding
IOCL has retained the core engineering burden in its catalyst micro-regeneration unit tender.
The latest clarification allows only limited configuration flexibility.
It does not dilute metallurgy, analyzer, pressure, temperature or process-safety requirements.
The unit is intended for light naphtha isomerization, catalytic reforming and continuous catalytic reforming studies.
It includes liquid and gas feed systems, reactors, gas/liquid separation, online analyzers, interlocks and emergency provisions.
Bidders asked for clarification on material of construction for liquid lines, valves, fittings and reactor internals.
IOCL said the technical specification prevails.
That keeps the cost-sensitive metallurgy requirement intact.
This matters because the additive dosing system must handle corrosive chemicals including DMDS, DEDS, CS2, CCl4, PCE and methylene chloride.
IOCL has given limited flexibility on analyzers.
Single analyzers with multiple ranges or cells may be considered.
But CO, CO2 and O2 measurement requirements still remain strict.
The company also kept regeneration pressure and temperature within the original specification range.
The vendor must design the reactor system accordingly.
HAZOP responsibility also remains with the vendor.
The study must be conducted by a certified HAZOP professional, and recommendations must be incorporated.
Relief is mainly commercial and interface-related.
CO generated during regeneration will be handled through IOCL’s blower system.
Payment is clarified as 90% on supply and acceptance, with the balance after installation and commissioning.
The key point is simple.
IOCL has opened the door to configuration flexibility, not engineering-risk dilution.
