The invention relates to the technical field of coal chemical and petrochemical equipment, in particular to a low-pressure thermodynamic equilibrium method of a pressure reduction system. The method comprises the following steps that I, the pressure reduction system is determined; II, upstream operation is performed; and III, downstream operation is performed. The low-pressure thermodynamic equilibrium method is applicable to the pressure reduction system under working conditions of the high temperature and the high pressure, the hardware and maintenance costs can be reduced, and the safety and the reliability of the system can be improved; and most pipelines and equipment belong to the low-voltage level, the potential safety accident rate is low, and the hardware and maintenance costs arelow. 本发明涉及煤化工与石油化工设备技术领域，具体公开了种减压系统的低压热力平衡方法，包括以下步骤：、确定减压系统；二、上游操作；三、下游操作。本发明低压热力平衡方法适用于高温高压工况下的减压系统，能够降低硬件及维护成本，并提高系统安全可靠性，且大部分管线及设备均为低压等级，潜在安全事故率低，硬件及维护成本低。
