美国7月丙烯合约价格上涨6美分/磅

据ICIS网站7月31日消息 美国7月丙烯合约结算价较6月上涨6美分/磅，因生产问题持续，现货价格升至一年高位。

7月聚合物级丙烯（PGP）合约收于32.5美分/磅（716美元/吨），化学级聚丙烯（CGP）交货价为31.0美分/磅。

此次合约价格是自2018年6月以来最大的单月涨幅，当时合约价格较上月上涨8美分/磅。

7月PGP期货价格为29.5-39.0美分/磅，而6月为21.5-28.0美分/磅。

影响美国PGP生产的停机事件包括：位于德克萨斯州自由港的陶氏丙烷脱氢（PDH）装置、位于德克萨斯州巧克力湾的英力士裂解装置、位于德克萨斯州Point Comfort的美国福尔摩沙塑料公司的裂解装置以及德克萨斯州亚瑟港的巴斯夫道达尔裂解装置。

此外，由于乙烷在美国蒸汽裂解原料中所占份额比以往任何时候都要大，而且随着寒冷月份对丙烷和丁烷的加热需求增加，预计不会动摇，因此丙烯的共生产量也有所减少。

裂解乙烷生产乙烯和有限的副产品，而裂解丙烷、丁烷和其他分子量较大的原料生产丙烯和其他化学品。

此外，由于汽油需求低迷、美国炼油厂利用率持续走低，导致炼油厂级丙烯（RGP）产量下降，可以使用分离装置将RGP升级至PGP。

尽管美国丙烯供应面临一些短期至中期生产限制，但可能足以满足2020年下半年缓慢复苏的需求。

全球经济放缓可能意味着今年剩余时间对丙烯及其衍生物的需求疲软，如果冠状病毒病例继续激增，需求可能进一步疲软。

丙烯的主要出口是作为聚丙烯（PP）的原料。丙烯还用于生产丙烯腈（ACN）、环氧丙烷（PO）、一些醇类、异丙苯和丙烯酸。

美国主要丙烯生产商包括雪佛龙菲利普斯化学、企业产品公司、埃克森美孚、希尔资源和壳牌化学。

US July propylene contracts rise by 6 cents/lb as production issues persist

US July propylene contracts settled at a 6 cent/lb increase from June as spot prices rose to one-year highs amid ongoing production issues.

The settlement puts July polymer-grade propylene (PGP) contracts at 32.5 cents/lb ($716/tonne) DEL (delivered) and chemical-grade propylene (CGP) at 31.0 cents/lb.

The settlement marks the largest month-on-month increase since June 2018, when contract prices rose 8 cents/lb from the prior month.

Front-month PGP traded in July at 29.5-39.0 cents/lb, compared with 21.5-28.0 cents/lb in June.

Outages affecting US PGP production include: Dow's propane dehydrogenation (PDH) unit in Freeport, Texas; INEOS's cracker in Chocolate Bayou, Texas; Formosa Plastics Corporation USA's cracker in Point Comfort, Texas; and BASF Total's cracker in Port Arthur, Texas.

Also, co-production of propylene was reduced as ethane's share of the US steam cracking feedslate is greater than it has ever been and is not expected to falter as heating demand for propane and butane rises in the colder months.

Cracking ethane produces ethylene with limited co-products, while cracking propane, butane and other heavier feeds yields propylene, among other chemicals.

Furthermore, continued low US refinery utilisation amid depressed gasoline demand has resulted in less refinery-grade propylene (RGP) production. RGP can be upgraded to PGP using a splitter.

Although US propylene supply faces a few short-to-medium-term production constraints, it is likely to be sufficient to meet slowly recovering demand in the latter half of 2020.

A slow global economy likely means demand weakness for propylene and its derivatives for the remainder of the year, with the possibility of further weak demand if coronavirus cases continue to spike.

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.
