Technology - Ammonia Refrigeration for Refinery process

An advanced ammonia refrigeration unit recovers gasoline and liquefied petroleum gas (LPG) from refinery fuel gas header streams. This waste heat-powered technology cools the waste stream, causing the condensation of valuable liquid products that would otherwise remain in the stream. In addition, this technology raises the column capacity of fluid catalytic crackers by reducing the burden of overloaded wet-gas compressors. This technology is also applicable to main stream industrial refrigeration operations.
Benefits
1. Delivers temperatures as low as -50°F.
2. Payback time of 2 years.
3. Decreases annual CO2 emissions, indirect CDM benefit.
4. Increases refinery throughput.
