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?

ESD valve

Prevent failure of emergency and plant protection valves

ESD, HIPPS, and other fail-safe or critical valves typically incorporate an actuator that must stroke the valve in the event of an irregular process condition. If the critical valve does not perform its function at the time of the distressed event, the consequences to life, property and the environment can be catastrophic. Partial stroke testing helps determine the likelihood that an  emergency shutdown valve will operate on demand.

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.
