據(jù)《美國(guó)化學(xué)周刊》6月15日消息，美國(guó)企業(yè)產(chǎn)品公司（Enterprise Products）正評(píng)估在得克薩斯州博蒙特附近投資50億美元建設(shè)乙烷裂解裝置。該裝置的乙烯生產(chǎn)能力為200萬(wàn)噸/年，將建在企業(yè)產(chǎn)品公司位于該州博蒙特附近內(nèi)奇斯河上的博蒙特海洋西部碼頭設(shè)施。提交給得克薩斯州當(dāng)?shù)毓賳T的一份申請(qǐng)減稅的文件估計(jì)，建設(shè)工作將于2024年第二季度開(kāi)始。企業(yè)產(chǎn)品公司發(fā)言人表示，該公司尚未做出最終投資決定，對(duì)該決定或投資時(shí)間表的進(jìn)一步評(píng)論還為時(shí)過(guò)早。

去年12月，企業(yè)產(chǎn)品公司聯(lián)合首席執(zhí)行官和公司負(fù)責(zé)石化業(yè)務(wù)的高級(jí)副總裁表示，該公司一直在考慮建造一個(gè)裂解裝置，以供應(yīng)那些不想自己建造裂解裝置的衍生品生產(chǎn)商。

企業(yè)產(chǎn)品公司目前沒(méi)有乙烯生產(chǎn)資產(chǎn)，但經(jīng)營(yíng)著一個(gè)乙烯出口終端以及存儲(chǔ)和管道資產(chǎn)，作為乙烯制造商的公開(kāi)市場(chǎng)存儲(chǔ)和交易中心。

當(dāng)前企業(yè)產(chǎn)品公司的博蒙特海洋西部碼頭包括三個(gè)深水碼頭和一個(gè)駁船碼頭，為原油和相關(guān)產(chǎn)品的進(jìn)出口提供便利。

該公司在休斯敦航道的Morgan’s Point設(shè)施運(yùn)營(yíng)著一個(gè)乙烯出口碼頭，設(shè)計(jì)產(chǎn)能為100萬(wàn)噸/年的乙烯。該公司最近表示，該終端的實(shí)際出口能力達(dá)到設(shè)計(jì)能力的125%。企業(yè)產(chǎn)品公司已宣布計(jì)劃到2023年下半年將出口終端擴(kuò)大50%，到2025年將其擴(kuò)大一倍，達(dá)到200萬(wàn)噸/年以上。

企業(yè)產(chǎn)品公司已經(jīng)告訴投資者，美國(guó)乙烯經(jīng)濟(jì)性支持石化擴(kuò)張，大量的乙烷供應(yīng)可以支持投資。今年4月，企業(yè)產(chǎn)品公司在一次投資者活動(dòng)上表示，按照目前的經(jīng)濟(jì)性，在美國(guó)新建一套150萬(wàn)噸/年的乙烷裂解裝置比歐洲的石腦油裂解裝置多產(chǎn)生10億美元的利潤(rùn)。

其他油氣中游企業(yè)也在考慮進(jìn)入乙烯生產(chǎn)領(lǐng)域。Energy Transfer Partners今年5月表示，該公司也在評(píng)估墨西哥灣沿岸的一個(gè)裂解裝置項(xiàng)目。該公司表示，在做出最終投資決定之前，正與客戶進(jìn)行談判，以確保達(dá)成長(zhǎng)期收費(fèi)協(xié)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(kāi)的油氣中游公司獲得了一份合同，該公司將在美國(guó)新建一套世界級(jí)規(guī)模的烯烴裝置。KBR表示，這套位于墨西哥灣沿岸的設(shè)施每年將能夠生產(chǎn)240萬(wàn)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.
