據ICIS網站6月29日消息 美國6月丙烯合約結算價較5月上漲0.5美分/磅，因生產問題導致現貨價格上漲。

6月聚合物級丙烯（PGP）合約定為26.5美分/磅（584美元/噸），化學級丙烯（CGP）價格為25.0美分/磅。

這是自去年9月合約價格達到39美分/磅以來的首次上調。

由于生產問題抑制了供應，現貨價格在整個月份上漲。

6月PGP交易價格為21.50-28.00美分/磅，而5月份為20.00-24.00美分/磅。

巴斯夫道達爾石化公司的裂解爐在德克薩斯州的亞瑟港仍處于關停狀態，乙烷只占裂解爐原料的四分之一左右，剩下的部分由分子量更大的丙烯原料組成，因此此次大修所需的丙烯供應量比美國平均裂解爐的丙烯供應量大得多。

6月4日，企業產品公司德克薩斯州蒙特貝爾維尤丙烷脫氫（PDH）裝置首次報道關停，PDH的丙烯產能為75萬噸/年。

最大的丙烯衍生物聚丙烯（PP）的需求顯示出逐步改善的跡象，尤其是在包裝行業，但由于家電和汽車行業的持續低迷，尚未恢復到危機前的水平。

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

美國主要丙烯生產商包括雪佛龍菲利普斯化學公司、企業產品公司、埃克森美孚公司、希爾資源公司和殼牌化學公司。

US June propylene contracts settle at an increase amid production issues

US June propylene contracts settled at a 0.5 cent/lb increase from May, as spot prices rose amid production issues.

The settlement puts June polymer-grade propylene (PGP) contracts at 26.5 cents/lb ($584/tonne) DEL (delivered) and chemical-grade propylene (CGP) at 25.0 cents/lb.

The settlement marks the first increase since September, when contract prices reached 39 cents/lb.

Spot prices rose throughout the month as production issues curbed supply.

Front-month PGP traded in June at 21.50-28.00 cents/lb, compared with 20.00-24.00 in May.

BASF Total Petrochemicals' cracker remains down at Port Arthur, Texas. Ethane only comprises around one-quarter of the cracker's feedslate. The remainder consists of heavier, propylene-yielding feeds, so the outage removes more propylene supply than at an average US cracker.

Enterprise Products' Mont Belvieu, Texas propane dehydrogenation (PDH) unit was first reported offline on 4 June. The PDH has a propylene capcity of 750,000 tonnes/year.

Demand for the largest propylene derivative, polypropylene (PP) is showing signs of gradual improvement, particularly in the packaging sector, but has not yet recovered to pre-crisis levels due to continued sluggishness from the appliance and automotive sectors.

The main outlet for propylene is as a feedstock for 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.
