In systems where compressors separate the oil containing section from the compression chamber, monitoring the presence of liquid hydrocarbons is crucial. Liquid hydrocarbons can contaminate the compressed gas, potentially leading to hazardous situations or equipment malfunction. The oil used in the compressor can break down or leak into the gas stream, creating a risk of fires or other safety issues.

Monitoring for liquid hydrocarbons ensures that any leaks or excess oil in the compression chamber are detected early. This scrutiny is vital for maintaining compliance with safety standards and protecting both equipment integrity and personnel safety.

Gaseous hydrocarbons and high temperature are indeed important parameters to monitor in certain contexts. However, in this specific scenario, they do not address the direct concern of liquid hydrocarbons contaminating the compressed gas. Thus, the focus on liquid hydrocarbons is most pertinent for ensuring system safety and reliability in the context of the separation mentioned in the question.
