Independent Cooling Water Advisory for Saudi Arabia — Refining & Petrochemical Integrated Complexes

Saudi Arabia's refining, petrochemical, and upstream assets operate some of the world's largest and most thermally complex cooling water systems. Industrial Water Advisory delivers independent, vendor-neutral expertise for the integrated complex operators and engineering teams that manage these critical systems.

From Jubail Industrial City and Yanbu to the Ghawar and Shaybah upstream fields, Saudi Arabia's industrial base operates recirculating cooling water systems under extreme ambient temperatures, high TDS makeup water, and demanding reliability standards. The kingdom's Vision 2030 industrial expansion and the ongoing buildout of NEOM and downstream petrochemical projects are creating new demand for independent water program governance.

Program Challenges

Cooling Water Challenges in Saudi Arabia

01

High Ambient Temperature & Thermal Stress

Saudi Arabia's extreme summer ambient temperatures push cooling tower approach temperatures to limits that challenge conventional treatment programs. High skin temperatures in exchangers accelerate scaling and require specifically calibrated inhibitor and biocide programs.

02

High TDS & Brackish Makeup Water

Many integrated complexes in Jubail and Yanbu rely on desalinated or partially treated seawater-derived makeup. Competing ion interactions — particularly between sulfate, bicarbonate, and calcium — require sophisticated saturation modeling beyond standard LSI calculations.

03

Multi-Vendor Management Across Integrated Complexes

Large integrated complexes in Saudi Arabia frequently operate with multiple chemical service vendors across interconnected cooling circuits. Independent oversight of vendor performance, program consistency, and contract compliance is a growing requirement.

04

Corrosion Under Insulation & System Integrity

The combination of high ambient humidity in coastal sites and intermittent cooling system operation creates CUI and microbiologically influenced corrosion risks that require independent assessment separate from the chemical treatment vendor.

05

Vendor RFP for Long-Term Service Contracts

Multi-year chemical service contract cycles at Saudi Arabia's major refining and petrochemical complexes benefit from independent technical input on specifications, performance guarantees, and evaluation criteria.

Eliminated Calcium Phosphate Deposition in Ethylene Compressor Intercoolers — Payback Under 2 Days

An ethylene production facility was experiencing calcium phosphate deposition in compressor intercooler cooling water circuits, creating a direct threat to unit reliability. The incumbent service vendor had not identified the root cause, and routine cleaning cycles were masking the underlying program failure.
What We Did
  • Identified phosphate over-treatment combined with high calcium makeup water as root cause through Competing Ion Saturation Modeling
  • Redesigned inhibitor program to eliminate excess phosphate while maintaining corrosion protection
  • Recalibrated cycles of concentration to reduce calcium loading at the intercooler heat flux
  • Established deposit coupon program in the compressor intercooler circuit for ongoing monitoring
Results Achieved
  • Calcium phosphate deposition eliminated in the compressor intercooler circuits
  • Payback on the independent advisory engagement achieved in under 2 days of avoided production loss
  • Compressor intercooler cleaning interval extended significantly, reducing maintenance burden
  • Inhibitor spend reduced through elimination of excess phosphate dosing
