Solving the "Long Flowing Water" Problem of Mechanical Sealing Cooling System

Recently, Shaanxi Yanchang Petroleum (Group) Yulin Refinery implemented energy-saving technical transformation on the mechanical seal system of the depentane oil pump of the DCC naphtha hydrogenation unit, which solved the problem of long water flow in the mechanical seal cooling system and the total energy consumption of the equipment.
Achieve "dual control" of volume and intensity
.

According to reports, since the de-pentane oil pump was put into use, the mechanical seal cooling system has used circulating water for cooling.
The circulating water is cooled by the mechanical seal cavity and discharged directly to the open ditch to be sent to the water supply and drainage workshop
.

In response to the above problems, the joint third workshop conducted an in-depth investigation on the energy consumption reduction solution of the old energy-consuming equipment, combined with the actual operation of the equipment, and formulated a washing and cooling plan for the mechanical seal auxiliary system
