Air compressor piping: Moisture separators are typically installed immediately after the intercooler to remove condensed water before the next compression stage.
Correct Answer: after the intercooler
Introduction / Context:Intercoolers drop the temperature of compressed air between stages, causing water vapor to condense. Proper placement of moisture separators protects downstream stages and equipment.
Given Data / Assumptions:
- Multi-stage compressor with intercooling and (often) an aftercooler before storage.
- Cooling the air below its dew point condenses water that must be removed.
Concept / Approach:Because most condensation occurs where temperature is reduced sharply, the separator is placed right after the intercooler. This removes liquid water before the air enters the next compression stage. A second separator is commonly used after the aftercooler before the receiver, but the primary, definitive location is after the intercooler.
Step-by-Step Solution:
Compression raises temperature and reduces relative humidity.Intercooling reduces temperature; water condenses.Install separator immediately after the intercooler to capture condensate.Dryer or aftercooler and a final separator may follow before storage.Verification / Alternative check:P&IDs for typical compressor packages show knock-out pots/separators downstream of each cooler.
Why Other Options Are Wrong:
- Before intercooler: Little to no condensation yet; ineffective.
- Between aftercooler and receiver: Often used as an additional separator, but the question asks generally—first essential location is after the intercooler.
- Before first stage suction: Unrelated to condensation removal from compressed air.
Common Pitfalls:Assuming a single separator is sufficient; multi-stage systems usually need separators after each cooler.
Final Answer:after the intercooler
