高压加氢设备是炼油厂中的关键设备之一。以往,加氢反应器多属冷壁结构形式,即在反应器内壁衬上100毫米厚的大颗粒珍珠岩混凝土保温层,壳体本身的壁温不致过热。这种结构不可避免地使反应容积减少,从而降低了有效空间的利用。如果衬里不好,尤其在接管处,局部地方会发生过热而处于高温状态,影响安全生产。随着我国现代化建设对石油制品 High-pressure hydrogenation equipment is one of the key equipment in the refinery. In the past, hydrogenation reactor is mostly cold-wall structure, that is, the reactor wall lining 100 mm thick perlite concrete insulation layer, the shell itself wall temperature will not overheat. This structure inevitably reduces the reaction volume, thereby reducing the effective space utilization. If the lining is not good, especially at the takeover, overheating occurs in some places and is in a hot state, affecting safety in production. With the modernization of China’s petroleum products
