G: what is the emptying line for.

Hi Fakhr
Welcome to the Forum.
Given your posts so far with direct questions about Sabroe plant you are involved with.
I am assuming "Flooded / LPR / Wet return" type Industrial plant is not your Speciality?
In the UK and & Ireland there has to be a PID (Pipework and Valve diagram for the relevant equipment displayed in or near to the plant room.
So that the Emergency services etc. can identify the flow of a system and its relevant Isolation Valves.

May I suggest you speak to your employers about some training with Sabroe or Others!

Here's the PID. Also please explain the vessel encircled in black. it has something to do with the lubrication oil, 1/4'' dia pipe is connecting and leaving all compressors to this vessel. Oil separator is just below every compressor. also each compressor block has its own oil cooling system. i think its an additional cooling system for the compressor?
