???? 據ICIS網站3月30日消息 由于墨西哥灣沿岸的產量從2月中旬的冬季風暴造成的中斷中恢復，大多數市場參與者的美國3月份丙烯合同結算價比2月份下降了18.5美分/磅（408美元/噸）。

????3月份的環(huán)比降幅為2008年以來最大的一個月，此前一個月的環(huán)比增幅為有史以來最大。

????然而，聚合物級丙烯（PGP）和化學級丙烯（CGP）的價格分別為70.0美分/磅和68.5美分/磅，仍遠高于三年來的平均水平（分別約為43.0美分/磅和41.5美分/磅）。

????截至目前，3月份的PGP期貨交易價格為53-85美分/磅，2月份為85-125美分/磅。

????隨著冬季風暴導致的停產，美國丙烯供應繼續(xù)放緩。然而由于庫存低和需求強勁，市場緊張狀況持續(xù)存在。

????盡管大多數丙烯生產廠已恢復生產，但開工率仍低于風暴前的水平。

????然而，冠狀病毒疫苗的加速推出和被抑制的需求預計將擴大第三季度的季節(jié)性需求上升。如果事實證明是這樣，丙烯市場將從流化催化裂化（FCC）裝置獲得大量供應。

????隨著經濟的重新開放和美國新的經濟刺激方案刺激了工業(yè)品的消費，對大多數丙烯衍生物的需求保持健康。

????丙烯的主要出口是作為聚丙烯（PP）的原料。丙烯還用于生產丙烯腈（ACN）、環(huán)氧丙烷（PO）、一些醇、異丙苯和丙烯酸。

????美國主要的丙烯生產商包括雪佛龍菲利普斯化工公司、企業(yè)產品公司、埃克森美孚、希爾資源公司和殼牌化工。

????US March propylene contract prices plummet as production recovers from winter storm

????US March propylene contracts for the majority of market participants settled at an 18.5 cents/lb ($408/tonne) decrease from February as Gulf Coast production recovered from disruptions caused by mid-February's winter storm.

????Coming just one month after the largest-ever month-on-month increase, March's month-on-month decrease is the steepest since 2008.

????However, at 70.0 cents/lb for polymer-grade propylene (PGP) and 68.5 cents/lb for chemical-grade propylene (CGP), prices remain well above the three-year averages of around 43.0 cents/lb and 41.5 cents/lb, respectively.

????Front-month PGP thus far in March has traded at 53-85 cents/lb, compared with 85-125 cents/lb in February.

????US propylene supply continues to loosen as production ramps up following winter-storm related shutdowns; however, market tightness persists due to low inventories and strong demand.

????While most propylene-producing plants are back online, operating rates remain below pre-storm levels.

????However, accelerating roll-outs of coronavirus vaccines and pent-up demand are expected to amplify Q3's seasonal demand upswing. If this turns out to be the case, the propylene market will get an influx of supply from fluid catalytic cracking (FCC) units.

????Demand for most propylene derivatives remains healthy as re-opening economies and a new US stimulus package are spurring consumption of manufactured goods.

????The main outlet for propylene is as a feedstock for polypropylene (PP). Propylene is also used to produce acrylonitrile (ACN), propylene oxide (PO), a number of alcohols, cumene and acrylic acid.

????Major US propylene producers include Chevron Phillips Chemical, Enterprise Products, ExxonMobil, Flint Hills Resources and Shell Chemical.
