Oxidations in the heterogeneous gas phase of fixed or fluidised bed reactors are often used for production of bulk chemicals.
Molecular oxygen is the major oxidant used in these reaction steps. Depending on the applied process either - pure oxygen (e.g. for production of vinylacetate); oxygen enriched air (e. g. for production of acrylonitrile); or air (e.g. for production of maleic or phthalic anhydride) can be used as a gaseous oxidant.
Fluidized bed oxidations are often operated by means of oxidized air, because of its high nitrogen content , which provides an effective fluidized gas stream for solid particles
The addition of pure oxygen to the oxidation air or the direct oxygen injection into the reactor can reveal considerable benefits to the customer:
- Higher plant capacity
- Backup of air compression
- Relief of waste gas treatment
- Enhanced flexibility of plant operation
In addition, the realisation of such an oxygen system comes along with remarkable low investment costs. We offer the optimum solution regarding process knowledge, equipment and gas supply systems.
