Automation for Vapor Recovery Units
VRU units recover hydrocarbon vapors and liquefy them again. MCS is not the manufacturer of these units, but a specialist for their control systems and visualization.
What we do on VRU units
- Modernization of control systems, often from S5 or older S7 systems to current Siemens platforms.
- Modernization of HMIs with WinCC-based operator interfaces.
- Automation adjustments when compressors, membrane stages, absorbers, pumps or sensors are changed during the plant lifecycle.
Why VRU work needs rare expertise
VRU projects are classic brownfield engineering: existing processes must be understood, documented and developed further while protective functions remain intact. Add hazardous-area constraints, often short shutdown windows and the combination of S5 experience, process understanding and current Siemens competence.
