摘要

Based on space arrangement, size and running parameters of equipments and pipes in CH4-CO2 reforming with carbonaceous catalyst, this paper establishes calculation model of frictional resistance and local resistance, analyzes pressure loss of equipments and pipes by model, and optimizes the size of some equipments and pipes.The result shows that O2 accumulator tank, reheating furnace and O2 pipes have much pressure loss.After optimization, total pressure loss of system reduced from 8260.6 Pa to 3289.9 Pa.When entrance pressure is 40 MPa,exit pressure was 0.0367 MPa.%基于重整反应系统的设备和管道尺寸、空间布置和设计运行参数等基础数据,研究并建立了主要设备、管道摩擦阻力和局部阻力计算模型,采用该模型分析了系统内各设备、管道和管道元件的压降,并对压降较大的设备和管道进行了尺寸优化.研究和优化结果表明,重整反应系统中,氧气缓冲罐、加热炉、氧气管道0G101～OG104等设备压降较大.对设备和管道的尺寸进行优化后,系统总压降由8 260.6 Pa降低到3 289.9 Pa;当系统入口压强P1=40 Mpa时,系统出口压强P2=0.036 7 Mpa.
