Abstract:

 The accuracy of process calculation of LPG loading pump is related to the efficient operation of LPG loading facilities. However, there are deviations both in the calculated pump head and the NPSHa based on the existing process calculation model, thus affecting the actual production of LPG loading facilities. Therefore, it is important to modify the process correlations of loading facilities to reduce the adverse impact of calculation deviation on actual production. Taking the LPG loading facilities of a factory in northwestern China as the example, this paper corrects the process correlations of LPG loading facilities and optimizes the process calculation model and process parameters of LPG loading pump based on theoretical analysis and practical operation experience.  The results show that the operation effect of the loading pump is improved in actual production after optimization.
