Automatic Reactor Sampling:

S2 Engineering offers an innovative Automatic Reactor Sampling system designed to address one of the highest risks in reactor processes—sampling process media at elevated temperatures. Traditional sampling methods often lead to spillovers, exposure, and various quality-related issues, posing significant risks to both personnel and product integrity.

Our advanced sampling system operates automatically under vacuum, pulling a pre-established sample quantity directly into a sealed container within a closed-loop system. This ensures that the operator remains fully isolated from the product media, significantly reducing the risk of exposure and contamination.

The system is powered by an optical sensor and features a clear sampling pot, allowing operators to visually monitor the sampling process at all stages. Additionally, the design facilitates integration with distributed control systems, making operation seamless and efficient. Unlike conventional systems, our sampling system is easy to clean, fast to operate, and minimises risk, thereby ensuring both safety and product quality.

Chemical Resistant Reactor Solutions:

S2 Engineering offers a range of high chemical-resistant reactor solutions, including chemical-resistant vessel charging systems. One example is our StanCoat high chemical-resistant coating, which is applied to the S2 Reactor Charging Isolator (Glove Box) and supporting systems, providing superior protection against corrosive substances. These solutions are not only effective for highly corrosive applications but are also conducive for food-grade environments.

A specific application example includes the handling of Hydrogen Bromide (HBr), a highly explosive and corrosive liquid. The HBr is received in a drum and transferred into a glove box (50Kg capacity). Inside the glove box, the drum is opened and a vacuum is applied inside the reactor to safely draw the product from the drum directly. Additionally, the system is equipped with nitrogen purging to ensure safe operation.

S2 Reactor Manufacturing:

S2 Reactors are meticulously manufactured by a skilled and highly experienced team of coded welders, engineers, and quality professionals. Our manufacturing process begins with the rigorous inspection of raw materials, ensuring full material traceability throughout the production cycle.

After fabrication and machining, all welds are subjected to Non-Destructive Testing (NDT) to verify joint integrity, in accordance with the latest ASME and international pressure vessel standards. We perform 100% static testing on every pressure vessel/assembly before dispatch and can also conduct dynamic testing of the equipment if required, ensuring the highest standards of safety and performance.

These comprehensive manufacturing practices and specialised solutions ensure that S2 Reactors meet the most stringent quality standards, delivering reliable, durable, and high-performing solutions for industrial processes.
