據《美國化學周刊》6月15日消息,美國企業產品公司(Enterprise Products)正評估在得克薩斯州博蒙特附近投資50億美元建設乙烷裂解裝置。該裝置的乙烯生產能力為200萬噸/年,將建在企業產品公司位于該州博蒙特附近內奇斯河上的博蒙特海洋西部碼頭設施。提交給得克薩斯州當地官員的一份申請減稅的文件估計,建設工作將于2024年第二季度開始。企業產品公司發言人表示,該公司尚未做出最終投資決定,對該決定或投資時間表的進一步評論還為時過早。
去年12月,企業產品公司聯合首席執行官和公司負責石化業務的高級副總裁表示,該公司一直在考慮建造一個裂解裝置,以供應那些不想自己建造裂解裝置的衍生品生產商。
企業產品公司目前沒有乙烯生產資產,但經營著一個乙烯出口終端以及存儲和管道資產,作為乙烯制造商的公開市場存儲和交易中心。
當前企業產品公司的博蒙特海洋西部碼頭包括三個深水碼頭和一個駁船碼頭,為原油和相關產品的進出口提供便利。
該公司在休斯敦航道的Morgan’s Point設施運營著一個乙烯出口碼頭,設計產能為100萬噸/年的乙烯。該公司最近表示,該終端的實際出口能力達到設計能力的125%。企業產品公司已宣布計劃到2023年下半年將出口終端擴大50%,到2025年將其擴大一倍,達到200萬噸/年以上。
企業產品公司已經告訴投資者,美國乙烯經濟性支持石化擴張,大量的乙烷供應可以支持投資。今年4月,企業產品公司在一次投資者活動上表示,按照目前的經濟性,在美國新建一套150萬噸/年的乙烷裂解裝置比歐洲的石腦油裂解裝置多產生10億美元的利潤。
其他油氣中游企業也在考慮進入乙烯生產領域。Energy Transfer Partners今年5月表示,該公司也在評估墨西哥灣沿岸的一個裂解裝置項目。該公司表示,在做出最終投資決定之前,正與客戶進行談判,以確保達成長期收費協議。
今年3月,總部位于休斯敦的KBR公司宣布,它已從一家未公開的油氣中游公司獲得了一份合同,該公司將在美國新建一套世界級規模的烯烴裝置。KBR表示,這套位于墨西哥灣沿岸的設施每年將能夠生產240萬噸輕烯烴。

Enterprise Products plans $5-billion US ethylene investment
Enterprise Products is evaluating a $5-billion investment in an ethane cracker near its Beaumont, Texas, site, according to filings with local officials. The plant would have capacity for 2 million metric tons/year (MMt/y) of ethylene. It would be built at Enterprise's Beaumont Marine West terminal facility on the Neches River near Beaumont, Texas. A filing with local Texas officials requesting a tax abatement estimates that construction will start in second-quarter 2024. The company has not made a final investment decision and further comment on decision or investment timelines would be premature, said an Enterprise spokesman
In December, Enterprise co-CEO Jim Teague and Chris D’Anna, the company’s senior vice president of petrochemicals, told that the company had been considering building a cracker to supply derivative producers who don’t want to build a cracker themselves.
Enterprise does not own ethylene production assets today but operates an ethylene export terminal as well as storage and pipeline assets that serve as an open market storage and trading hub for ethylene makers.
Enterprise’s Beaumont Marine West terminal today includes three deepwater docks and one barge dock that facilitate the exporting and importing of crude oil and related products.
The company operates an ethylene export terminal located at its Morgan’s Point facility on the Houston Ship Channel with nameplate capacity to load 1 MMt/y of ethylene. The company said recently that the terminal is operating at 125% of nameplate. Enterprise has announced plans to expand the export terminal 50% by the second half of 2023 and double it to more than 2 MMt/y by 2025.
Enterprise has told investors that US ethylene economics support petrochemical expansion with significant supplies of ethane available to support investment. At current economics a worldscale 1.5 MMt/y ethane cracker generates $1 billion more in profit than a European naphtha cracker, Enterprise said at an investor event in April.
Other midstream players are also considering entering into ethylene production. Energy Transfer Partners said in May that it was evaluating a cracker project along the Gulf Coast, as well. The company said it was in discussions with customers to secure long-term tolling agreements prior to a final investment decision.
In March, KBR (Houston, Texas) announced that it has secured a contract from an undisclosed midstream company for a world-scale US olefins plant. The Gulf Coast facility will be able to produce 2.4 million metric tons of light olefins annually, KBR says.
