Light hydrocarbons leakage

Vented risers should be provided on most cooling towers to release only light hydrocarbon leakage from the cooling water before the spray header. No ignition or source of spark should be within 30 m of the vented riser. 

Schumacher (1996) contended that long-term leakage of hydrocarbons can establish locally-anomalous redox zones that favour the development of a diverse array of chemical and mineralogical changes. The bacterial oxidation of light hydrocarbons can... 

If gland oil leakage becomes excessive, either because of a defective seal or excessively high gland oil pressure, the vacuum bottoms pump will lose suction. The gland oil, which consists of a relatively light hydrocarbon, flashes on contact with the hot resid product. The evolved vapor gases up the pump.
