Natural-gas liquids: Gasoline condensed from natural gas by compression and cooling is known as which type of gasoline?

Introduction:Gas production streams can contain heavier hydrocarbons that condense as liquids under compression and cooling. The condensed gasoline-range material has a specific name in refining terminology.

Given Data / Assumptions:

• Source: Natural gas streams.
• Process: Compression and cooling.
• Product: Gasoline-range liquid hydrocarbon mix.

Concept / Approach:When separated from natural gas at the wellhead or gathering systems by pressure and temperature reduction, the gasoline-range liquid is called casing-head gasoline (a natural gasoline or condensate fraction).

Step-by-Step Solution:

Verification / Alternative check:Terminology in upstream/midstream operations distinguishes straight-run (from crude distillation), polymer gasoline (polymerization), and reformate (catalytic reforming) from this natural-gas-derived fraction.

Why Other Options Are Wrong:

• Polymer gasoline: Produced via polymerization of olefins, not gas condensation.
• Unleaded gasoline: Refers to additive policy, not origin.
• Straight-run gasoline: From crude distillation, not gas plants.
• Reformate gasoline: From catalytic reforming of naphtha.

Common Pitfalls:Confusing “condensate/natural gasoline” with straight-run or reformate due to overlapping boiling ranges.

Final Answer:Casing-head gasoline
