Application example 2
Gas expansion in an ammonia production plant.
The ammonia production in a Polish chemical factory is directly supplies with natural gas over a double-stage Spilling gas expander.
The natural gas is pre-heated with steam before entering the both expansion stages and can therefore enter the production process with high gas temperatures of approx. 35 °C after the machine.
Benefits for the customer
- Cost saving by reduced external electricity purchase
- Increased operating efficiency due to energy utilisation of natural gas
