摘　　要：合理确定GHA70A型罐车对二甲苯加热卸车终温对应的加热时间,可以有效地降低加热蒸汽消耗量,起到节能降耗的目的.由于PX罐车加热的现场实验费时、费事且耗资,因此建立了罐车加热过程中的二维模型,应用计算流体软件FLUENT对罐车温度场进行数值模拟分析.PX加热的数值模拟温度与实验温度相对误差最大值为2.87%,说明该数值模型用于分析PX罐车加热过程是可靠的.利用模拟分析方法获得加热蒸汽压力为0.3 MPa时,罐车内PX的平均温度与加热时间的关系式,从而可以准确地确定现场加热时间,有效地指导现场加热实际操作.Reasonably determining the heating time corresponded to heating unloading terminal temperature of GHA70Apara-xylene tanker can effectively reduce steam consumption and achieve the purpose of saving energy and reducing consumption.Due to the PX tanker heating field experiment is time-consuming,laborious and costly,two-dimensional model of the tanker in heating process is established and the numerical simulation analysis of temperature fields is conducted by the computational fluid software FLUENT.Comparison of the numerical simulation and experimental temperatures show that the maximum relative error is 2.87%,indicating that the numerical model used to analyze the PX tanker heating process is reliable.While the heating steam pressure is 0.3 MPa,the relationship between the average temperature of PX and heating time can be obtained by the method of simulation analysis,which can accurately determine the spot heating time and effectively guide the actual operation.
