整体多层包扎式高压容器应用于加氢反应器的前景

加氢反应器的典型特点是高温、高压和临氢环境。目前典型结构是板焊式或锻焊式,存在制造周期长、成本高和焊缝容易产生裂纹等问题。整体多层包扎式高压容器是一种无深厚焊缝的高压容器,已成功应用于氨合成塔和尿素合成塔。分析了整体多层包扎式高压容器的技术进展,指出应用整体多层包扎方式制造加氢反应器可以明显降低成本、缩短制造周期,并可现场制造,将给加氢反应器的制造带来重大变化。从整体多层包扎式高压容器发展情况和其特性来看,其安全性是有可靠保障的,应用于加氢反应器是可行的。当然,需要从理论、设计、制造、材料、标准、规范等开展进一步的工作。

The prospect of application of integrated multilayer-wrapped high pressure vessels for hydrogenation reactor

The features of hydrogenation reactor are high temperature and high pressure,exposed to hydrogen atmosphere. Currently there are two typical structures of hydrogenation reactor. They are the welded hydrogenation reactor with thick plates and the welded hydrogenation reactor with the forgings. However,the manufacturing cycle is long,and the cost is high and its weld seams have the risk to crack easily. The integrated multilayer-wrapped high pressure vessel is a kind of high pressure vessel that has no profou...
