Repsol’s industrial complex in Sines is one of the most advanced in Europe and incorporates digital technologies and solutions with the aim of improving energy efficiency, electrifying processes, and promoting the circular economy.
The energy company also seeks to optimise the efficiency of fuel loading and unloading processes, as well as to ensure safety in product transfer operations.
For this reason, Repsol has relied on Montrel to manufacture three automated skids: one for unloading isopentane tanks, another for loading and unloading hexene trucks, and a third for unloading butene trucks with vapour recovery.
This project consolidates Montrel’s position as one of the leading suppliers of skids for loading and unloading petrochemical products.
OUR WORK
The scope of the contract awarded to Montrel covers the engineering, manufacturing, functional testing and supply of three skids with local and remote operating capabilities for the control and automation of three liquid loading and unloading systems.
The main components include pumps, compressors, programmable logic controllers (PLCs), human-machine interfaces (HMIs), discharge arms and buffer tanks, ensuring safe, efficient and reliable operation of the transfer processes.
The system developed by Montrel guarantees maximum safety and efficiency in industrial operations thanks to its intelligent and automated design.
The local PLC continuously monitors process conditions, ensuring total control over each operating parameter. If an interlock signal is activated, such as a local emergency stop, a disconnected coupling or a pump failure, the system automatically executes a safe shutdown, closing valves and stopping the process to ensure the safety of people and the working environment.
Repsol has also awarded Montrel the commissioning of the three skids, to verify, validate, and document that all equipment is safe, functional, and fully prepared for start-up.

ADDED VALUE
This project reinforces Montrel’s commitment to energy efficiency, sustainability and operational safety, as the built-in butene gas recovery system allows the remaining gas to be utilised once the liquid transfer is complete, optimising process performance.
State-of-the-art equipment has also been incorporated, including custom-made discharge arms, which significantly reduce the risk of spills or leaks compared to manual transfer operations.
”Our advanced automation at Repsol's new polyolefin logistics platform redefines liquid transfer with flow control using PID ramps and vapour recovery, setting a standard for operational efficiency, precision, and total safety through constant process monitoring.
