ON DEMAND - Discover how Atlas Copco's innovative Compander technology combines multi-stage turbo compressors and radial expansion turbines into a single, compact, and cost-effective integrally geared machine. This webinar highlights the key technical features of the Compander and presents real-world case studies from the petrochemical industry, highlighting significant operating cost savings in process gas compression.
Learn how integrating expansion turbines recovers substantial power from off-gas streams — power that would otherwise be wasted when vented through a valve. Compared to standalone turbine trains, the Compander's integrated design offers an economically attractive solution with a superior cost-saving ratio.
As energy and CO2 emission costs rise, maximising waste energy recovery becomes essential. See how the Compander can help your operations stay efficient and sustainable.
Case studies overview:
- Hydrogen peroxide production: a four-stage air compressor with inter-cooling and two parallel expander stages mounted on a common pinion effectively recovers energy from a nitrogen stream to power the compressor, reducing energy consumption.
- Phenol production: a three-stage air compressor paired with a single expander stage processes oxygen-depleted air from the reactor, optimising energy use within the system.
- Nitric acid production: a three-stage air compressor and two series-mounted expanders on separate pinions efficiently manage hot gas streams from the oxidiser reactor, reducing waist energy losses.
The objective is to demonstrate how companders provide an economically attractive and efficient approach to combine integrally geared compressors with turboexpanders. This allows process and plant designers to fully leverage waste energy recovery, improving process efficiency and reducing energy costs, especially considering rising energy prices and emissions-related expenses.
