Hydrogen of high purity is required for various applications in chemical and petrochemical production processes. Usually, hydrogen purity is monitored by measurement of traces of carbon monoxide and carbon dioxide by means of IR-photometers, often in potenially explosive atmospheres. Solutions for this application are analyzing systems based on analyzer S720.The special design of the NDIR gas analyzer S720 allows a sum measurement of CO and CO2 at a measuring range of 0 - 50 ppm with only one IR module. The flameproof enclosure and the functional, low-maintenance gas conditioning provide a high degree of safety which is required for hazardous areas Zone 1. Our solution:
Sulfuric acid is one of the most important basic chemicals. During production according to the contact process SO2 is catalytically converted to SO3. The SO2 concentration in the process is in the higher vol% range. Its continuous monitoring is made photometrical with S700 at room temperature or with MCS300P at higher temperatures. The emission of the process can be monitored with SICK measuring technology. Our solution:
Methyl acrylate is required for the production of absorbers and is a primary product of polymers. Acrolein is formed as an intermediate product in acrylic acid production. For process optimization, its concentration time course is monitored with a gas analyzer. Our solution:
Methyl cellulose is mainly used as glue.It is also used as thicking agent or stabilizer in food industry. The production of methyl cellulose is continuously monitored, e.g. by measurement of chloromethane and dimethyl ether. Our solution:
