What are the safety precautions for water treatment operations in new atmospheric and vacuum distillation units?

Firstly, when the oil pump draws in water, its specific gravity increases significantly, which can cause the pump to trip due to excessive current. If it does not trip, the motor may get damaged; therefore, it is essential to control the pump’s discharge volume and current properly； Secondly, in the case of new installations, there is often a lot of slag and other debris in the pipelines, which can easily clog the filters at the inlet of the pumps as well as those on the flow meters. It is necessary to clean these filters promptly to prevent impurities from entering the pumps and flow meters and damaging their delicate internal components, thereby avoiding delays in starting up the equipment ； Thirdly, during water intermodal transport, media and components that cannot come into contact with water must be properly isolated, such as by using blind flanges, as manual valves still pose a risk of leakage ； Fourth, after the water transport process is completed, the water must be removed completely. Additionally, the dehydration process using hot oil should be carried out slowly and carefully, to prevent a sudden rise in pressure due to residual water, which could damage the equipment.
