Safety valves devices have been proven over time; they however have the tendency to “flutter” – characterized by intense high frequency opening and closing of valves – or they tend to deviate from the intended operating conditions. They are sized assuming the worst case scenario and are such over dimensioned in most cases. They are the limiting factor in the operation of a technical plant. more

Rupture disk devices in technical plants prevent unsafe over pressurization of vessels, tanks and other apparatus. Once the burst-pressure is reached, the busting disk is activated making an opening to the relief line. The flow resistance in the relief line must not be too high during relief – this may otherwise increase the pressure upstream of the rupture disc device further. more

In the chemical industry, PLC interlock systems, which are adaptable to processes, are increasingly being used to protect chemical reactors. However, the complexity of designing PLC interlock systems is currently very high. The aim of SmartHIP is to reduce this effort by developing a modular kit, which allows to parametrize a process safely and is applicable for different reactor types and processes at the same time. more
