石油圈中国石化新闻网讯 据安迅思新闻休斯敦1月3日消息，新的一年美国丙烯产能有望出现大幅增加，因为有一套新建丙烷脱氢（PDH）装置将建成投产，同时还有一些新建裂解装置将陆续投产，但丙烯下游衍生物产能仍保持稳定。
企业产品合伙公司（EPP）一套75万吨/年的新建PDH装置原计划是在2017年9月投产，但是受8月底超强飓风哈维的影响，该装置的开工时间被迫推迟至2017年11月份。虽然市场人士表示，该装置的开工活动已经在11月底开始，但是EPP在提交给政府的文件中表示，该装置的开工活动将持续到今年1月底，这也意味着该PDH装置正式投产要到今年2月份。
除了该PDH装置延期投产外，飓风哈维导致美国多个炼油厂和烯烃装置的丙烯生产非计划停工。虽然很多非计划停工在飓风过后的几周内恢复生产，但是一些烯烃装置一直停工至当年的11月份，其中有一套装置停工至12月份。 张春晓 摘译自 安迅思新闻

OUTLOOK ’18: US propylene production set to expand in 2018 -With the start-up of a new propane dehydrogenation (PDH) unit and several crackers, propylene capacity in the US is set to expand during 2018, while downstream capacity remains steady. Enterprise Products’ 750,000 tonne/year PDH unit had been expected to start-up in September prior to Hurricane Harvey. Effects from the hurricane delayed the unit’s commissioning schedule, and the company had said it expected to start up the unit in November. While market sources have said that start-up activities for the unit had begun in late November, the company said in a government filing that start-up activities could continue into late January. Aside from the delay in the PDH start-up, Hurricane Harvey in late August had caused multiple outages for propylene production from refineries and olefin units. Although many outages resolved in the weeks following the hurricane, several olefins units were offline into November and one into December.
