Abstract:

Based on the statistical analysis of the historical operation data and the simulation results of the steady-state model, the analysis of the purification equipment and the public system was carried out to analyze the low-load operation conditions of the high-sulfur natural gas purification plant in this paper. In the process, the relationship between the energy consumption and the running load was clarified. Then, the advanced method of energy saving in the internal structure of the natural gas purification plant was put forward based on the optimization of the load distribution with the lowest unit cost. Further, the whole plant production self-use gas and the power consumption were studied with the change of the load. Energy-matching relationship of main devices with common system was determined. Meanwhile, the advanced practice of saving the common system was proposed, as well as the guiding opinions for the low-load energy-saving operation of the domestic high-sulfur natural gas purification plant.
