On March 5th, a news came from Liaoyang Petrochemical Company that the two scientific research achievements of the liquid ammonia analysis sampling device and the liquid ammonia analysis and evaporation device independently developed by the company successfully passed the review of the State Intellectual Property Office and obtained the patent for utility model.

In view of the deficiencies of the existing technology, two patents enable the sampling operation to be completed by switching the valve and switching the connection. The evaporation process is reduced from 5 to 8 hours to 30 minutes, and real-time sampling and real-time analysis are realized, which not only ensures the analysis of data. The timeliness and accuracy of the evacuation also avoided the risk of safety and environmental protection and drastically increased the efficiency of liquid ammonia analysis.
