Applications

Sofis products and solutions are used in many applications, to guarantee safe valve operations and improve efficiency.

Heat exchangers in a refinery

Prevent over-pressurisation of heat exchangers

While heat exchangers must be maintained and tested in a live process, they are installed in parallel, allowing one to be maintained, while the other takes over the process. Changing over between heat exchangers requires strict adherence to procedures, to avoid hazardous mistakes. How to avoid accidents when changing-over heat exchangers ?

Hard-to-reach valves

Avoiding accidents when operating hard-to-reach valves

Manual valves are relatively inexpensive, simple to operate, and easy to install. They are present in large quantities across most process plants. Due to space constraints or other design or economic limitations, some manual valves may be positioned in difficult to operate spaces. This can result in valves being in an uncomfortable and even dangerous position for the operator to manoeuvre the handwheel or the lever. How to avoid accidents?

Pipeline pigging installation

Guaranteeing safe pigging operations

Pigging helps improve pipeline flow, increase operating efficiency, and reduce costs and downtime. The main benefit of this type of maintenance is that it can be carried out without interrupting the process in operation. However, pigging operations are also high-risk events. Since the operation is hazardous, pigging is to be carried out by experienced professionals. How can you prevent accidents and guarantee safe pigging operations?

Pump start up

Guaranteeing safe pump start up operations

In many industries, pumps are an essential part of processes. Industrial pumps are used to move many different types of products, including water, chemicals, petroleum, wastewater, oil, sludge and slurry. Industrial pumps are designed specifically for use in harsh or heavy-duty applications. Still, they can be damaged as a result of incorrect valve operations during pump start-ups. Correct operations are indispensable to guarantee a long life of pumps. avoid dangers and minimise plant downtime.

valve interlocks securing pressure relief valves

Safely isolating pressure relief valves

Relief valves require regular maintenance and calibration. Plants install spare relief valves in their process systems to maintain sufficient relief capacity when a pressure relief valve is taken offline for maintenance. Switchover procedures require that the spare pressure relief valve is commissioned before any relief valve can be taken offline for maintenance. Pressure relief valves are typically operated manually. This means that operations are prone to human error, leading to dangerous situations.

Valve interlocks are used to secure safe ethylene cracking.

Guarantee safe feedstock purification processes

Sieving and drying feed stock is necessary to avoid damage to your chemical manufacturing equipment. This process of regeneration is extremely dangerous, and it is critical that a correct line-up of valves is achieved before starting the regeneration process. Unfortunately, there are many accidents tied to this procedure. Safe feedstock purification processes prevent accidents, loss of containment and damaged pipes.

Ethylene process plant

Guaranteeing safe LDPE processes

The LDPE production process is complex and dangerous. It involves ultra-high pressure and medium temperature. During the LDPE production process, a small mistake can have disastrous consequences. Incorrect valve operations can lead to significant loss of containment, injuries, and considerable damage and disruption to the plant. Sequence control products like valve interlock systems offer s simple and effective way to guarantee safe LDPE processes, without the need to actuate the valves.

Corrosion in pipeline

Ensuring the removal of corrosion monitoring probes before pigging

Corrosion monitoring is an important tool in the battle against premature degradation of pipelines. The corrosion-related failures in pipelines costs billions of dollars in production losses, downtime, environmental contamination, injuries, and fatalities. To prevent damage to intrusive corrosion probes that have not been removed before initiating a pigging operation, these probes can be easily integrated into an interlocked valve operation sequence.
