Technology for Reduction of Coke yieldand Increase in Distillate Yield
Refineries all over the world are increasingly processing heavier crudes for maximization of refinery margins. As a result of this, Delayed Coking Units have gained importance for bottom of the barrel upgradation for improved profitability. However, high yield of low grade coke from the process is a bottleneck in improving the refinery margin further. To enhance the profitability in thermal cracking
process, IndianOil R&D has developed Ind-CokerAT technology, for residue upgradation with lower coke make & superior distillate yields in comparison to a conventional Delayed Coker technology. Apart from significant improvement in the GRM, ease of integration with existing Delayed Coker unit & its implementation with minimum investment provide an additional advantage.
Ind-CokerAT R
Salient Technology Features Operational flexibility due to Dual mode operation (either Ind-CokerAT or Coker mode) Automatic Top & Bottom un-heading valve for enhanced safety Refinery waste sludge can be processed for its disposal

Major Benefits Reduction in Coke yield & increase in distillate yield compared to conventional Delayed Coker Unit Higher conversion of low-value residues to distillates with minimum capital investment Processing of wide range feedstocks - offers flexibility for enhancing refinery margin through
processing of cheaper crudes Cost effective technology can be add-on to any existing Delayed Coker Unit for better margins Technology can be provided for grassroot unit for better margins
Commercial Experience Wide operating experience with commercial Delayed Coker units Excellent technical support and troubleshooting expertise Commercially demonstrated in one of the IndianOil refineries with 3 MMTPA unit capacity (Coke
yield reduction by ~ 5.0 wt% with corresponding distillate yield increase by ~ 4.0 wt%)
Upcoming units Ind-CokerAT technology along with revamp of Delayed Coker of 0.662 MMTPA - commissioning in
one of the Indian refineries by 2021-22
