催化重整新装置的建设和老装置的扩能改造

CONSTRUCTION OF NEW CATALYTIC REFORMING UNITS AND CAPACITY EXPANSION OF OLD ONES

我国催化重整的加工能力将面临一个大提高时期 ,在老装置改扩建和新装置建设中 ,应注意如下一些问题 :①新建装置究竟选择半再生重整工艺还是连续重整工艺 ,主要的决定因素是对重整汽油辛烷值和氢气产量的需要 ,装置规模也是重要因素。UOP公司和法国石油研究院的两种连续重整技术的水平相当 ,选择时应视具体情况而定。建议推广具有我国自主知识产权的“逆流移动床重整”技术。②在老装置改扩建中 ,应充分利用现有的设备尤其是投资较高的加热炉和压缩机 ,处理量提高的幅度应以少更换或少改动高投资设备为原则进行确定 ;半再生重整装置改为连续重整时 ,可采用分步实施的方法。③应重视扩大重整原料来源、应用新型设备 。

In construction of new catalytic reforming units and capacity expansion of old ones,following problems should be noted: (1) For a new reforming unit,selecting semi regeneration or continuous catalyst regeneration reforming process depends on the requirements of the octane number of reformed gasoline, the hydrogen yield and processing capacity of the unit.The counterflow moving bed reforming process with the intellectual property of our own should be preferred.(2) In capacity expansion of the old units,the existing equipment,especially expensive heaters and compressors, should be fully utilized. The semi regeneration reformers can be converted into CCR units in steps.(3)Enough attentions must be paid to feedstock sources expanding, application of new equipment and utilization of small scale semi regeneration reformers.
