Improving Efficiency, Reliability
& Emissions Performance Across
Oil & Gas Operations

Flue gas cooling and waste heat recovery

For more than 100 years, LJUNGSTRÖM has supported the oil and gas industry with engineered heat transfer systems, waste heat recovery technologies, and advanced manufacturing solutions designed for the most demanding process environments.

As refineries, gas processing plants, and petrochemical facilities face rising fuel costs, aging infrastructure, and increasing emissions pressure, LJUNGSTRÖM helps operators recover lost energy, reduce operational risk, and extend the life of critical assets—without disrupting production.

LJUNGSTRÖM Solutions
for Oil & Gas Facilities

High-Efficiency
Heat Transfer Solutions

LJUNGSTRÖM is a trusted provider of air preheaters, flue-gas heat exchangers, and gas-gas heating systems engineered for harsh oil and gas service.

Our systems help oil and gas operators:

  • Reduce stack temperatures and flue-gas heat loss
  • Improve fired heater, boiler, and process efficiency
  • Lower fuel gas consumption
  • Increase overall energy efficiency using existing assets

By capturing energy that would otherwise be lost, facilities unlock measurable fuel savings and emissions reductions.

Modernization for Aging
Power Plant Equipment

Many oil and gas facilities operate equipment that is 30–50+ years old. LJUNGSTRÖM specializes in targeted modernization and life-extension solutions that improve reliability without full system replacement.

We support:

  • Replacement and upgrades of heat transfer internals, bearings, seals, and structural components 
  • Early identification of degradation to prevent unplanned outages 
  • Reduction of collateral damage to downstream process and emissions equipment 
  • Upgrade planning aligned with turnarounds and maintenance windows  

This proactive approach reduces forced outages, improves unit availability, and stabilizes long-term performance. 

Advanced Manufacturing Built for Oil & Gas Operations 

LJUNGSTRÖM’s vertically integrated advanced manufacturing capabilities eliminate supply-chain uncertainty for critical oil and gas components. 

Benefits include: 

  • Shorter and more predictable lead times 
  • Precision manufacturing of large, complex, and custom components 
  • Tight quality control from engineering through fabrication 
  • Reduced execution risk during turnarounds and critical repairs 

With in-house manufacturing, oil and gas operators receive fit-for-purpose components built to perform in corrosive, high-temperature, and fouling-prone environments. 

Designed for Harsh Oil & Gas Process Environments 

Oil and gas systems operate under extreme thermal, chemical, and mechanical stress.  

LJUNGSTRÖM products are engineered to withstand: 

  • High temperatures and thermal cycling 
  • Corrosive flue gases and process streams 
  • Fouling, erosion, and particulate loading 
  • Continuous operation in critical process units 

Supporting Emissions Reduction
and Energy Efficiency Goals 

Improving heat transfer efficiency is one of the fastest and most cost-effective ways to reduce emissions in oil and gas operations. Efficiency improvements today create flexibility for tomorrow’s regulatory and operational demands. 

LJUNGSTRÖM solutions help facilities: 

  • Reduce CO₂ emissions through lower fuel consumption 
  • Improve energy intensity metrics 
  • Support compliance with tightening environmental regulations
  • Prepare for future carbon reduction and capture initiatives  

LJUNGSTRÖM Products for Oil & Gas

Air Preheaters for
Refinery & Process Heaters 

LJUNGSTRÖM air preheaters improve thermal efficiency in fired heaters, boilers, and process units by recovering heat from flue gas to preheat combustion air. 

Designed to: 

  • Lower stack temperatures and heat loss 
  • Reduce fuel gas usage 
  • Improve heater efficiency and stability 
  • Reduce CO₂ emissions  

Heat Transfer Internals (Baskets, Seals & Structural Components) 

Degraded internals are a leading cause of efficiency loss and operational instability in oil and gas units. 

LJUNGSTRÖM manufactures replacement and upgraded internals to: 

  • Restore heat transfer performance 
  • Reduce air-to-gas leakage 
  • Improve draft control and combustion stability 
  • Extend equipment life without full replacement 

 

Guide & Support Bearings
