Esfahan Refinery – Package “C” Offsite & Utilities

The National Iranian Oil Engineering and Construction Company (NIOEC) initiated the Esfahan Refinery Upgrading Project to address de-bottlenecking and upgrading needs at the Esfahan Refinery. The project’s ultimate objectives are to reduce or minimize fuel oil production, increase gasoline production, and upgrade the refinery’s products to meet international standards. These objectives will be achieved through the installation of new units and the de-bottlenecking/revamping of existing units.

To achieve these goals, the project has been divided into five separate sub-projects and contracts:

1. Contract A: RHU, RFCC, and PRU units.
2. Contract B: All upgrading and revamping work within the existing refinery area.
3. Contract C: Interconnecting piping and networks, flare system, and utilities.
4. Contract D: Diesel Hydrotreating Units, SRU, TGTU, Amine Treating, Sour Water Stripping, Gasoline Hydrotreating, and LPG Merox.
5. Contract E: HPU and PSA units.

Contract C, awarded to Tehran Raymand Consulting Engineers, is primarily responsible for supplying and distributing the required utilities for the OSBL (Outside Battery Limits) process units, designing the flare system and gathering networks, and interconnecting process and utility piping. This involves the following engineering activities:

A. Basic and Detailed Process Design:

• Newly added units where the basic design had not been performed by the original designer, including the new Nitrogen Generation Package (Unit 81).

B. Endorsement, Development, and Detailed Design:

• Procurement Engineering Services for utility units, including:
  • Unit 35: Flare System
  • Unit 41: Steam & Power Generation
  • Unit 42: Water System
  • Unit 43: Fuel System
  • Unit 44: Plant & Instrument Air System
  • Unit 45: Interconnecting & N2 Distribution
  • Unit 46: Waste Water Treatment
  • Unit 50: Tankage
  • Unit 80: Nitrogen

C. Interface Management

D. Field Engineering Services
