The food and water that nourish our bodies. The clothing that keeps us warm. The fuel that powers our vehicles on the roads, across the oceans and in the air. Chemicals are the building blocks of our everyday lives - and of the global economy. Safe, efficient oversight of chemical plants and processes represents one of the most pressing challenges in the development of a sustainable future. That's why chemical operators must protect every infrastructure investment with rugged, reliable measurement technology. Siemens has an array of high-performance field instruments to monitor the health...

Ethylene plant Raw material storage Floating roof tanks are used to store large quantities of naphtha, a petroleum product. Each tank is comprised of an open-topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. Tank level monitoring ensures continual availability of raw material for ethylene processing - a challenging task carried out by Siemens radar level instruments mounted on top of the still pipe. M, Level: SITRANS LR250 • Compact, radar-based level measuring device for use in...

Natural gas pre-treatment The typical modern ammonia-producing plant first converts natural gas into gaseous hydrogen in a process known as reforming. During the natural gas pre-treatment, the process stream is compressed, pre-heated and desulphurized. Siemens devices allow for the adjustment of process components in the correct ratio via defined interaction of flow and compression. S Flow: SITRANS F O delta p • Differential pressure measurement with SITRANS P320/ P420 results in universal flow monitoring for liquids, gases and vapors • Provides accurate results even with high temperatures...

Pre-clean and compression of air As a first step in the air separation process, the air is sucked in, pre-filtered of dust and compressed to about 6 bar. This creates heat and requires a first cooling interval. For maximum efficiency, the pre-cleaning and compression unit must be kept within a very specific range of operating parameters. Siemens measurement devices help to maintain an ideal environment for the process at all times, even under the most difficult conditions. H Temperature: SITRANS T series • Modular design makes it possible to customize the TS500 temperature sensor for most...

Batch stirred tank reactor Batch stirred tank reactors (STRs) generate a homogenous substance distribution, which results in high product yields and selectivities. STRs are generally used for the small-scale production of high-priced products and therefore require very accurate monitoring with Siemens field devices during the manufacturing process. S Pressure: SITRANS P420 • Easy-to-install pressure transmitter with automatic commissioning and self-adjustment of zero and span • New data logging function with up to 1500 measuring points - ready for digitalization • High accuracy of <0.04% 3...

Feed hoppers and metering deck In order to prepare the feed properly for the mixing process, exact measurement of the various ingredients including pigments, solvents, binders and additives is necessary. This often takes place at a central metering deck, where the liquids and powders are measured separately. Accurate flow and weighing instruments from Siemens assure consistently high levels of product batch quality and reproduction. S Flow: SITRANS F C MASS 2100/FCS300 with FCT030 • Coriolis flow system for direct control of valves in dosing applications • Wide range of sensor sizes...

Feedstock delivery Biogas processing starts with the transportation of renewable feedstock from the storage facility to the digester feeding system. Overfilled storage tanks and line blockage are significant concerns throughout the transportation process - but these challenges can be overcome with the right combination of Siemens flow, level and weighing instrumentation. S Flow: SITRANS F M MAG 5100W with MAG 6000 • Cost-efficient electromagnetic flow system capable of measuring aqueous slurries with short lead times • Accuracy of <0.4 % of flow rate • EPDM or NBR hard rubber liner for...
