Most of the basic chemicals, which are used in chemical industry, are produced in-house. Production processes are monitored with continuous analysis technology in order to ensure the product quality and trouble-free production processes. Compliance with environmental regulations is very important and thus also the use of the appropriate measuring devices.
Monitoring of the Hydrogen Purity in Pressure Swing Adsorption Plants
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. Best solution 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 application in hazardous areas Zone 1. Our solution:
Production of Sulfuric Acid according to the Contact Process
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 photometrically with GMS800 at room temperature or with MCS300P at higher temperatures. The emission of the process can be monitored with SICK measuring technology. Our solution:
-
SO2-measurement: NDIR analyzer GMS800 or analyzer MCS300P
-
Emission monitoring: Customized analyzer systems MKAS
Production of Acrylic Acid
Methyl acrylate is required for the production of absorbers and is an 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:
Production of Methyl Cellulose
Methyl cellulose is mainly used as glue. However, it is also used as thicking agent or stabilizer for a variety of applications in food industry. The production of methyl cellulose is continuously monitored, e.g. by measurement of chloromethane and dimethyl ether. Our solution:

Fertilizers are still major products of the chemical industry worldwide. Basically fertilizers consist of nitrates and phosphates. Nitrates are made of nitric acid and ammonia. Phosphates are produced by decomposition of phosphate minerals with sulfuric acid. The basic products for the production of fertilizers are:
Production of Ammonia
Ammonia is produced by a catalytical reaction according to the Haber-Bosch process. Basic materials are nitrogen and hydrogen. The NH3 emissions of the production facilities are continuously monitored. Our solution:
Production of Nitric Acid
Emission monitoring plays an important role in the production process of nitric acid. Whereas components such as NO and NO2 were monitored in the past, the focus now has been shifted to the reduction of greenhouse gases and monitoring of N2O. Our solution:
