Overview
Designed for use by a large utilities company in Germany, the plant produces hydrogen gas from water and mixes this with natural gas. This mixture is injected into the German gas grid for use by consumers.
ITI Group designed and installed a control and protection system that can be run autonomously while also monitoring safety critical data. The supervisory system provides a local and remote visualisation of the plant and key processes and alerts the utility company to any system anomalies. The control and protection system ensures a safe working environment for operators and provides an instant notification of alarms to key personnel. This enables the gas supplier to identify issues which could disrupt supply and improve customer service.
Fully integrated solution
TUV/CompEx certified engineering solution
Dedicated ITI team
Familiarity with the site and systems helped deliver the project on time and on budget
Safety First
Adhering to the clients’ functional safety and hazardous area assessments, the ITI solution employed Siemens fail-safe S7-300 F-rated PLC controllers and safety I/O modules with suitable SIL protection to meet a number of client defined Safety Instrumented Functions (SIFs).
Pepprl and Fuchs intrinsically safe barriers were used to provide a safe interface from the hazardous area signals which originated in Zone IIC T4.
A Siemens TP1500 15” Touchscreen running WinCC provides the operator with a holistic view of all processes.
Siemens GSM and GPRS modules provide access for remote monitoring of the process from the site in Germany.
All the equipment was housed within a number of control panels which were designed, built and tested in-house by ITI, including ATEX-certified panels.
Control hardware specification, design and build for numerous control panels
Compliance with Ex/ATEX requirements
Software specification, design and test, including safety and automated process area sequencing
