Casing head gasoline is the liquid

A) Butane B) Propane C) Natural gas D) Gasoline separated from wet natural gas by compression

Discuss

Answer & Solution

Answer: Option D

Solution:

In petroleum refinery engineering, casing head gasoline is the liquid gasoline separated from wet natural gas by compression (Option D).

Casing head gasoline is obtained during the initial processing of natural gas. When natural gas is extracted from underground reservoirs, it often contains liquid hydrocarbons, including gasoline, which are separated from the gas stream by compression. This gasoline, known as casing head gasoline, is typically a mixture of hydrocarbons and is used as a fuel or as a feedstock in various chemical processes.

Therefore, the correct option is Option D: Gasoline separated from wet natural gas by compression.
