Hello all,
Does anybody know the common practice used for draining an unloading arm which contains and transfers Volatile Organic Compounds (for example LPG, propylene, ethylene) and which is installed in a breasting island (away from land but not necessarily too far)?
I searched the web and found some practices like the following:
1. Drainage of the VOC into the sea.
2. Venting of the VOC in the atmosphere.
3. Pressurization of the arm and purging of the VOC to the plant (that accepts the substance).
4. Drainage of the arm in berth slop systems or transfer to a land slop system.
Thank you in advance,
Chris
