Preventive steam trap checks at bp

bp saves costs through proactive replacement of steam traps

The bp Rotterdam refinery is one of the largest and most advanced oil refineries in Europe. Here crude oil is processed into a wide range of products, including gasoline, diesel, kerosene and basic chemicals essential for various industries. Steam and condensate systems are essential in the refining process. Steam is used for various purposes, including keeping pipes at temperature, powering turbines and in the process to strip light components from heavier components. KLINGER plays a crucial role in the maintenance of the bp Rotterdam refinery's steam and condensate systems. With our technical expertise, we help the refinery operate efficiently and safely, contributing to the overall performance and sustainability of the facility.

The challenge

With it becoming increasingly important to deal properly with energy savings in the process industry, bp has been proactively improving the steam and condensate system in recent years. bp has done this by preventively measuring steam traps to see if they are functioning, leaking (internally) or clogged. Leaking steam traps result in (internal) steam leaks which causes water hammer and higher condensate back pressure and operational costs (fuel & CO2). Clogged steam traps lead to significant problems such as reduced heat transfer, pipe corrosion and erosion in appendages. These two failure mechanisms increase maintenance and operational costs by causing many steam leaks in the production units. There was a need at the refinery to be more predictable and proactively replace steam traps even before it visibly caused operational problems. This underlines the importance of regular maintenance and inspection to ensure safe and reliable operation of industrial plants.

The solution

Two years ago, bp Rotterdam and KLINGER sat down together to revive a new preventive maintenance strategy for the steam traps . After ten years of performing only visible corrective maintenance, a comprehensive survey was conducted on three assets to assess the individual condition of the steam traps . This analysis revealed that a significant number of steam traps were leaking or just plugged, highlighting the need for the steam trap survey conducted by KLINGER. These inspections on the three assets were the starting point for a major corrective maintenance program aimed at replacing and modernizing the existing steam traps.

"Furthermore, the steam traps strategy not only increased operational efficiency but also improved safety."

The result

Replacing and upgrading leaking and plugged steam traps has resulted in fewer visible steam leaks at the refinery, resulting in reduced maintenance costs due to less frequent need to use clamps on occurred pinholes. In addition, it has resulted in a more stable process within the refinery. Operating costs have also been reduced due to lower fuel consumption and CO2-emission costs. Furthermore, the steam trap strategy has not only increased operational efficiency but also improved safety. In winter, the operating environment is safer because there is no slipperiness due to iced condensate, and in summer there is no slipperiness due to algae growth caused by condensate leaks.
