Two technologies of Yulian were patented
Yanchang Petroleum Group Yulin Refinery declared two technologies of "a deaerator and fixed discharge expansion vessel combined with waste steam recovery device" and "medium pressure deaerated water pump outlet pressure control system", which has been authorized by the State Intellectual Property Office for utility model patents, which is the first time that Yulin Refinery has participated in patent application and has been successful
.
The former not only effectively recovers the steam emitted by the thermal deaerator and the fixed discharge expansion vessel, reduces the energy consumption of the production device, but also completely solves the noise pollution in the steam emptying process and eliminates the potential safety hazards on site; The latter reduces the pressure twice through two pressure reducing valves on the pressure control line, so that the pressure gradient of the pressure control line is reduced, which effectively solves the leakage problem
caused by the pressure drop of the pressure control line is too large.
Since the application of the two technologies, the working environment has been significantly improved, potential safety hazards have been eliminated, the comprehensive energy consumption of the device has been greatly reduced, the inspection and maintenance costs have been saved, and the stable and high operation
of the device has been promoted.
