Engineering Consultancy Services for Projects – TT Gantry 4 Bay Extension & 2500KL IFR Tank Construction with Allied Facilities at HPCL, Hassan Terminal

Hindustan Petroleum Corporation Limited (HPCL) - Hassan Terminal was commissioned in 2003 over an area of 102.82 Acres owned by HPCL. The products handled are MS and HSD. Products are received through pipeline from MRPL through PMHBL. It caters to the product requirement of 14 districts of Karnataka.

HPCL has received order from Government of India for commencing 20% ethanol blending with 80% Motor Spirit which is 20% EBP. To meet the 20% ethanol blend requirements, HPCL decided to check the adequacy and augment the ethanol system for 20% ethanol blend with increased storage capacity of ethanol. In order to handle the future growth in throughput of the Terminal, augmentation of TTG by 4 additional bays with bottom loading facility is planned. HPCL awarded the Detailed Engineering contract to iFluids Engineering to implement the augmenting facilities related to 20% EBP.

The existing Infrastructure for handling Ethanol:

  • Terminal has a tankage of 1020 KL in six underground tanks. Two tank farms of 3 tanks each (6 X 180 KL)
  • 4-Bay Ethanol gantry for Ethanol unloading by gravity unloading from trucks
  • Delivery to Loading Gantry is done through submersible pump for each UG tank
  • Pipeline network to Connect Ethanol unloading gantry – Tank farm – TT loading bay gantry

Proposed Ethanol tankage Infrastructure:

  • One No. 17 m Dia. x 12 m Ht. (2500 KL pumpable Qty) IFR Above ground tank with dyke
  • Pumps for Unloading Ethanol to AG tank & UG tanks (Existing)
  • Loading Pumps for delivering to TTG from AG tanks
  • Additional pumps for existing UG tanks for 2400 LPM
  • Pump house
  • Roads around tank farm
  • Fire hydrant network, MEFG, Sprinkler system, FOAM pourer system etc.
  • Drainage system, electrical system, miscellaneous civil works etc.
