Challenge
Chemical production processes generate gas mixtures that are often vented unused, even though they contain valuable components. At the same time, these gases place high demands on safety, monitoring and plant design.

Solution
By using reciprocating compressors, process gases can be compressed in a targeted manner and returned to the production cycle.

The compressors are designed for demanding gas compositions and enable safe and continuous operation under industrial conditions.

Implementation in Taiwan
In a plant for the production of ethylene glycol, various process gases such as methane, carbon dioxide and ethylene are recovered.

The piston compressor used compresses these gas mixtures and ensures their reliable return to the process. Safety-related requirements, such as ATEX compliance and continuous monitoring, are consistently taken into account.

Results

• Recirculation of valuable process gases into the production cycle
• Reduction of emissions and resource losses
• Safe operation through optimised plant design
• Continuous process monitoring and high plant availability
