Applications

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

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.

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.

Operator opening a large valve

Facilitate safe and ergonomic operation of large manual valves

Process facilities have many large valves spread across the facility. It is important to ensure that they are operated safely and correctly to prevent accidents, and to comply with health and safety guidelines and normsSometimes operational hazards go unnoticed and only become known when an incident occurs, leading to human injury, lost man days and other associated risks and costs. How can you guarantee effortless operation of large manual valves, to create a safer working environment, and minimize interruptions or shutdowns?

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?

Valve interlocks installed on a chemical offloading installation

Ensuring safe line-ups during chemical offloading in the water industry

The offloading and transfer of hazardous chemicals is a common operation carried out at water treatment and wastewater treatment plants. The operation involves road tankers transferring highly hazardous chemicals into the plant for use in the drinking water or sewage treatment process. If done incorrectly, this process can potentially have dangerous health, safety, and environmental consequences. Mechanical interlocks can provide engineered control measures to control the processes of the opening and closing of system valves, and the connection of hoses to plant fill points.

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.

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.

Radioactive level gauge

Prevent dangerous exposure to radiation sources

Gamma radiation is very penetrating and is scattered by dense materials. It is used for measuring the thickness of materials such as metals, detecting fill height or measuring density by detecting scattered radiation. To guarantee that radiation sources will not expose operators to radiation, they can be incorporated into a system of valve interlocks. This can either be a single, simple device, operated by rotating a handle or lever, or by multiple sources, operated using pneumatic actuators.

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.

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?
