The engineering task
A wet gas is compressed and then cooled to a specified temperature. Compression raises temperature and water-vapour partial pressure; subsequent cooling condenses part of the moisture.
Aftercooler and separator are coupled: cooler temperature and pressure drop determine condensate rate and separator gas volume. Liquid carry-over can damage downstream compressor stages or users.
Required design data
- Gas composition, humidity and suction state
- Suction/discharge pressure, efficiency and stages
- Aftercooling temperature and utility
- Allowable droplet carry-over and holdup time
Technical solution approach
Calculate compression
Determine specific work, power and discharge temperature including efficiency.
Balance aftercooling
Balance sensible cooling and condensation together; the final state provides gas and condensate rates.
Size the cooler
Match area, utility flows and pressure drops to the required outlet temperature.
Size the separator
Design gas area, droplet removal and condensate holdup for maximum load.
Protect the system
Blocked outlet, loss of cooling and pressure-control failure define relief requirements.
Expected deliverables
Suitable SOL ALPHA modules
The modules form a technically plausible toolchain. Their final selection and sequence will be confirmed during the later calculation against the applicable code and project conditions.
