Application fields of thermal oil plants
The chemical industry is one of the most important industries in Germany. In terms of turnover it is behind the vehicle construction and mechanical engineering just behind the electrical and electronics industry at fourth place, in terms of the persons employed at fifth place. The sector primarily produces intermediate goods for almost all production areas.
In the chemical industry, the availability of process heat in the high temperature range plays an important role. Thermal oil systems, for example, are used for the heating of polymerization plants, poly-condensation plants, for spinning head heating and for manufacturing polyester fibres, but also in the sector of plastic extrusion, the temperature control of kneaders, dryers, suction filters and reactors.
Example: Reactor heating
At H&R AG, a manufacturer of chemical-pharmaceutical specialty products based on crude oil and precision plastic parts in Salzbergen/Germany, reactors serve for the production of highly purified paraffin for medical products. H&R (1.550 employees worldwide, annual turnover of more than 1 billion EURO) disposes of one of the oldest but at the same time most modern lubricant refinery of the world.
Together with heat 11, the company installed a new plant for the heat supply of two high-pressure hydrogenation plants in 2013. In this process, unusual solutions were found. True to its motto “Oil is far too good for burning!” the medium-sized chemical specialist processes crude oil to more than 800 different products.
High value is set on the production plants being always on the latest state of the technology. The reactors newly installed in the course of a production expansion and increase in output of the two hydrogenation plants serve the production of highly purified paraffin and white oils for the pharmaceutical, cosmetics and food industry.
