随着我国炼油工业的不断发展,加氢、重整装置的处理能力不断扩大,主要设备反应器的直径和高度也在不断扩大。为避免在高温、高压下反应器的氢腐蚀,目前我国均采用反应器内壁衬内保温衬里的冷壁反应器。我厂原用火山灰水泥隔热混凝土作内保温衬里,但此混凝土线收缩大,原料来源也有困难。因此,我们针对此问题,结合材料的容重、导热系数,强度要求等性能,选用
With the continuous development of China’s oil refining industry, the processing capacity of hydrogenation and reforming units is constantly expanding, and the diameter and height of major equipment reactors are also constantly expanding. In order to avoid the hydrogen corrosion of the reactor under high temperature and high pressure, at present our country adopts the cold wall reactor lined with the inner lining of the reactor. Our factory originally used volcanic ash cement insulation for insulation lining, but the contraction of the concrete line, raw material sources are also difficult. Therefore, we address this issue, combined with the bulk density of materials, thermal conductivity, strength requirements and other properties, selection
