Gas Coolers

1. Determine if the package requires gas cooling if not already required by customer specifications.

Consider ambient conditions, anticipated operating conditions, geographical location, and customer

requirements.

2. The discharge gas temperature predicted by the Ariel Performance Program is the expected

temperature at the compressor cylinder discharge flange. Account for any heat loss between the

compressor cylinder and cooler inlet flanges and size the cooler accordingly.

3. Account for cooler fan power consumption when engine driven.

4. Cooler design and construction must comply with good engineering practice and industry standards

for heat exchangers.

5. Consider associated liquid condensates in the cooler design. This includes both heat load and

gas flow from top to bottom through the cooler sections.

6. Some applications require automated temperature control up to and including cooler bypass to

avoid excessive condensates and dense phase above critical point. Applications may include

heavy gases, CO2, acid gas, etc.
