Amongst other things, energy, steam, water and operation gases are required for the production of chemicals. Waste has to be handled environmentally friendly. The analyzers of SICK monitors emissions of the power generation process and the internal supply and distribution of operation gases. In waste disposal the measuring devices monitor pollutants released into the air as well as into water.
Generally chemical industry parks include fossil-fueled power plants to produce electricity as well as steam. For these power stations the same national regulations regarding emission monitoring are applied as for other energy producers. The operational measurements for controlling the combustion and the flue gas cleaning facilities are identical, too.
In addition to electricity, power stations in chemical parks also produce steam for process applications. For internal balancing the distributed amounts of steam have to be measured with gas flow meters. For this purpose contact-free ultrasonic measurement is particularly suitable because it requires no restrictions inside the pipelines. Our solution:
In large chemical production plants (e.g. in interconnected operation of chemical parks) operating gases are distributed to the different facilities. Normally, billing is made based on volume measurements. A precise measurement in combination with a reduced maintenance effort is achieved by ultrasonic gas flow measurement devices. Our solution:
There are very strict national regulations to be complied with regarding waste disposal and the emission of air pollutants and sewage.
Monitoring of sewages
Manufacturing processes in the chemical industry require water for cooling of production facilities, which is taken from rivers. The discharged waste water has to be continuously monitored for pollutants (e.g. contaminations caused by production or by failures). Normally, waste water which has not to be cleared is fed back into the river. Water that has to be cleared has to pass a sewage treatment plant before feeding back into the river. The parameter to be controlled is the total organic carbon (TOC) of the waste water. Our solution:
Combustion of chemical residues (hazardous waste incineration)
Very often large chemical plants have own incinerators. These facilities work in compliance with the regulations of incinerators for hazardous waste. In this case, particularly high demands on emission monitoring devices are given. SICK is worldwide leading in supplying metrological equipment for monitoring of emission and process parameters in waste incineration plants. Our equipment has successfully passed the relevant approvals. Our solution:
