1、2010年第1期总第37卷综述整体多层包扎式高压容器应用于加氢反应器的前景刘栋，宋鹏云，胡明辅，朱孝钦，潘宁(昆明理工大学化学工程学院，云南昆明650224)摘要：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

2、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。关键词：加氢反应器；整体多层包扎式；综述中图分类号：TE966文献标识码：A文章编号：1006—0316(2010)01—0001—04Theprospectofapplicationofintegratedmultilayer—wrappedhighpressurevesselsforhydrogenationreactorLIUDong
