Question 1 of 27070

Which of the listed substances is used as an adsorbing agent in the shipboard dehydration of refrigeration systems?

🔍 Key Concepts

• Difference between adsorption and absorption in drying systems • Common materials used in refrigeration system dehydrators/driers • Which substances are glycols/salts versus solid desiccants

💭 Think About

• First, decide which choice represents a solid material commonly packed in driers, rather than a liquid additive • Think about what you would physically find inside a filter‑drier canister used to remove moisture from refrigerant • Ask yourself which of these materials works by trapping water on its surface instead of mixing with it

✅ Before You Answer

• Identify which options are liquid glycols used as antifreeze or corrosion inhibitors, not solid drier media • Identify if any option is a salt used in absorption systems, not as a solid adsorbing desiccant in the refrigerant line • Confirm which option is well‑known as a granular or bead‑type drying agent (desiccant) used in many industrial driers
