Reduce chilling temperature to condense more propane and heavier components from sales gas without changing the refrigeration compression and equipment to operate under vacuum; accomplish this in a minimal footprint.
Modeling showed that adding a SUPERCHANGER Shell And Plate exchanger downstream of the chiller could reduce gas temperature to improve the propane recovery from 3 to 5% and lower the GHV of the sales gas.
- Installing a SUPERMAX Shell And Plate exchanger improved propane recovery by 13%.
- Reduction of the sales gas GHV by 2%, to contractual levels.
- The extra exchanger had a footprint of only 0.5 m2 (5 ft2), well within the required maximum available footprint of 1 m2 (10 ft2).
