How measurement technology is advancing sustainability in the chemical industry

In the chemical industry, waste is often caused by inaccurate process control or faulty batches. Precise, reliable data from process instrumentation can help here. Sensors from VEGA monitor chemical reactions with high accuracy and minimise waste by-products.

One example is the dosing of raw materials: Level sensors measure the exact quantities of material in tanks and prevent overdosing, which wastes raw materials. In reactors, pressure sensors provide real-time data on critical parameters, ensuring that the internal processes are closely controlled. The result: less waste and greater efficiency.

VEGA sensors also make a difference in the storage of raw materials. They help to manage inventory levels, avoid material overflow and reduce losses.

Practical examples of resource conservation

• Pharmaceutical industry: Synthesis processes require maximum precision in order to produce high-purity active ingredients and avoid waste. VEGA sensors monitor these processes and ensure quality.
• Plastics production: Here, sensors ensure that mixing ratios are accurately maintained, thereby avoiding faulty production and thus material waste.

All in all, VEGA sensors promote an increase in efficiency, which generates both economic and ecological benefits.

Hydrogen: Precision and reliability for the energy transition
The use of hydrogen is central to the decarbonisation of the chemical industry and the energy transition. The special properties of hydrogen – such as low density and extreme pressures and temperatures – place high demands on measurement technology.

VEGA sensors, for example radar level transmitters, monitor hydrogen tanks that are operated under high pressure or at temperatures as low as -253 °C. They enable precise control of quantities in storage and are not affected by pressure and temperature fluctuations. Pressure sensors that can measure up to 1000 bar play a central role in the safe handling of compressed or liquefied hydrogen.

VEGA sensors also make an important contribution in electrolysis, the key technology for producing green hydrogen. They monitor critical parameters like pressure and temperature, thus enabling efficient and stable production.

CCS: CO₂ capture for a climate-friendly future
CO₂ capture and storage (CCS) is indispensable for reducing emissions in the chemical industry. VEGA sensors ensure that these processes run safely and efficiently.

• Capture: VEGA sensors monitor the conditions in the facilities that capture CO₂ from exhaust gases and ensure maximum efficiency with their accuracy and reproducibility.
• Transport: When liquefied CO₂ is transported in pipelines, the sensors continuously measure the pressure to detect leaks.
• Storage: When CO₂ is stored in underground caverns or rock formations, the sensors ensure that the greenhouse gas remains safely contained.
