Rototherm has a significant offshore installation base across the North Sea, Middle East, South East Asia and Australia, working with key industry players, such as Shell, ExxonMobil and BP, demonstrating success in our designs and meeting the necessary process requirements. We ensure that the mechanical integrity of our systems are never compromised, which is why we maintain 100% record of successful operation and, in many occasions, this results in our team being brought in to replace malfunctioning RO designs that can lead to significant safety and cost implications for the user.
Multi-Stage ROs are typically required to reduce pressure down to atmospheric. This solution is increasingly common on offshore platforms where higher pressure drops and flow rates exist and control valves are expensive to install and maintain. For example, a multistage restriction orifice assembly is installed at the downstream of blow down valves. When blowdown valve opens to release the high pressure on its upstream, the RO at its downstream ensures that the flow is not excessive to overload the flare header. Usually the pressure drop in a blowdown circuit across an RO can be very high.
When designing a solution, Rototherm engineers always consider four critical factors:
• High pressure drop – ensuring that the required pressure drop is achieved with proven design
• Noise – achieving the lowest noise level (<85dBA according to international noise standards)
• Joule-Thompson Effect – considering the change in temperature across the assembly and subsequent impact on bore size and plate thickness
• Length – meeting the process requirements in the shortest overall length, especially when space is tight and limited.
