據(jù)油價(jià)網(wǎng)休斯頓報(bào)道，由于全球液化天然氣需求在可預(yù)見(jiàn)的未來(lái)將繼續(xù)增加，供應(yīng)“更綠色LNG”可能會(huì)讓生產(chǎn)商在這個(gè)蓬勃發(fā)展的市場(chǎng)上占據(jù)優(yōu)勢(shì)。法國(guó)油氣巨頭道達(dá)爾公司和德國(guó)西門(mén)子公司天然氣和電力部門(mén)時(shí)下正在合作進(jìn)行研究，這兩家公司屆時(shí)都將從中受益匪淺。

減少LNG液化設(shè)施的溫室氣體排放，提高LNG液化廠可靠性、可維護(hù)性、遵守法規(guī)和減少開(kāi)發(fā)成本是兩家公司這項(xiàng)研究的目標(biāo)。隨著政府嚴(yán)格的法規(guī)和企業(yè)指令的出臺(tái)，脫碳LNG的生產(chǎn)可以滿足對(duì)這種燃料的更多需求。作為最清潔的化石燃料，歐盟委員會(huì)將其視為減少排放和應(yīng)對(duì)氣候變化的極佳替代能源。

正如我們看到的綠色氫，一些國(guó)家已經(jīng)開(kāi)始承諾投資數(shù)十億美元來(lái)應(yīng)對(duì)氣候變化。為了實(shí)現(xiàn)這些目標(biāo)，美國(guó)一直特別青睞LNG，這是因?yàn)槊绹?guó)國(guó)內(nèi)的天然氣供應(yīng)充足，足以增加出口。

麥肯錫公司預(yù)測(cè)，到2035年底前，全球天然氣和LNG市場(chǎng)將繼續(xù)以每年3.6%的速度擴(kuò)大。

法國(guó)能源巨頭道達(dá)爾公司近年來(lái)一直在擴(kuò)大其能源投資組合，其中LNG被列為優(yōu)先項(xiàng)目。5月份，道達(dá)爾公司為莫桑比克的一個(gè)LNG項(xiàng)目籌集了150億美元，用于計(jì)劃在6月份的簽約。這個(gè)項(xiàng)目的投資額將擴(kuò)大到230億美元，成為非洲迄今最大的私人投資，項(xiàng)目融資將與大約20家銀行綁定。這個(gè)項(xiàng)目將把天然氣冷卻成液體用于出口。

西門(mén)子公司看到了LNG的巨大潛力，并采取了另一個(gè)主要聯(lián)盟。西門(mén)子公司為巴西里約熱內(nèi)盧的綜合LNG發(fā)電項(xiàng)目新聯(lián)合循環(huán)發(fā)電廠找到了股權(quán)投資伙伴。西門(mén)子公司與巴西Prumo物流公司和石油巨頭英國(guó)石油公司各擁有項(xiàng)目公司Gas Natural Acu (GNA)的三分之一的股份。

西門(mén)子公司將受益于探索在滾動(dòng)系統(tǒng)中燃?xì)廨啓C(jī)壓縮生產(chǎn)線的新研究。西門(mén)子公司旗下總部位于休斯頓的天然氣和電力部門(mén)生產(chǎn)用于發(fā)電的產(chǎn)品，如燃?xì)夂驼羝麥u輪機(jī)、發(fā)電機(jī)、渦輪機(jī)組件和定制OEM電廠解決方案。

這項(xiàng)新研究將考慮使用燃?xì)廨啓C(jī)和電動(dòng)驅(qū)動(dòng)的壓縮生產(chǎn)線，結(jié)合已證明的單混合制冷和雙混合制冷技術(shù)，用于動(dòng)力傳動(dòng)系統(tǒng)和電力系統(tǒng)的冷卻功能。另一個(gè)正在探索的方法是開(kāi)發(fā)旨在提高現(xiàn)場(chǎng)發(fā)電設(shè)施效率的技術(shù)；這可能包括熱回收系統(tǒng)、進(jìn)氣口空氣冷卻、輔助燃燒、可再生能源整合和電池存儲(chǔ)。

西門(mén)子公司能源石油天然氣部門(mén)首席執(zhí)行官Thorbjoern Fors說(shuō)：“該部門(mén)將通過(guò)應(yīng)用久經(jīng)考驗(yàn)的設(shè)備解決方案以及在項(xiàng)目的早期概念開(kāi)發(fā)和前端工程設(shè)計(jì)時(shí)通過(guò)向客戶提供金融、技術(shù)開(kāi)發(fā)和戰(zhàn)略支持來(lái)致力于支持LNG工業(yè)減少碳排放的努力。”“我們很自豪能夠繼續(xù)與道達(dá)爾公司合作，努力實(shí)現(xiàn)LNG廠排放的最低水平，并實(shí)現(xiàn)LNG生產(chǎn)的最高可持續(xù)性。”

作為協(xié)議的一部分，西門(mén)子公司將在LNG廠設(shè)計(jì)中研究探索液化和發(fā)電的可能性。最終的目標(biāo)是實(shí)現(xiàn)LNG的脫碳生產(chǎn)。但這兩家公司表示，其他效率也是總體目標(biāo)的一部分。這將包括利用數(shù)字化和自動(dòng)化平臺(tái)來(lái)優(yōu)化LNG廠設(shè)計(jì)，實(shí)現(xiàn)無(wú)縫項(xiàng)目執(zhí)行。

西門(mén)子公司認(rèn)為，人工智能、數(shù)字雙胞胎和預(yù)測(cè)分析等數(shù)字技術(shù)的應(yīng)用，為L(zhǎng)NG開(kāi)發(fā)商和運(yùn)營(yíng)商提供可觀的收益以及提高其設(shè)施的經(jīng)濟(jì)可行性。參與北極圈內(nèi)的哈默菲斯特LNG廠的西門(mén)子公司已經(jīng)能夠轉(zhuǎn)移LNG廠的計(jì)劃外停機(jī)時(shí)間。西門(mén)子公司開(kāi)發(fā)了一種先進(jìn)的數(shù)字系統(tǒng)，可以對(duì)整個(gè)系統(tǒng)進(jìn)行監(jiān)控并迅速做出反應(yīng)，以保證系統(tǒng)有效運(yùn)行。

Energy Giants To Bring Greener LNG To The Market

As global LNG demand continues to grow into the foreseeable future, supplying ‘greener LNG’ could give producers an edge in this burgeoning market. French oil and gas giant Total and Siemens Gas and Power division are conducting studies that could greatly benefit each company.

Reducing greenhouse gas emissions at LNG liquefaction facilities, and improving plant reliability, maintainability, regulatory compliance and development costs, are targets for the study. Decarbonizing LNG production can feed into more demand for the fuel with stringent government regulations and corporate mandates kicking in. Being considered the cleanest fossil fuel, the European Commission sees it as an excellent alternative energy to reduce emissions and combat climate change.

As we’re seeing with green hydrogen, several countries have started committing billions of dollars in a bid to combat climate change. The US has been particularly fond of LNG to meet these targets — and as the domestic gas supply is ample enough to grow exports.

McKinsey & Co. forecasts that the global gas and LNG market will continue to expand 3.6 percent each year through 2035.

Total has been expanding its energy portfolio in recent years, with LNG being prioritized. Last month, Total was able to round up $15 billion for an LNG-project in Mozambique for a signing scheduled in June. It will be expanding to $23 billion and make up Africa’s largest private investment yet, binding in about 20 banks. The project will chill natural gas into a liquid for export.

Siemens sees great potential in LNG, having taken on another major alliance. The company found equity investment partners for a new combined cycle power plant for the integrated LNG-to-Power project in Rio de Janeiro, Brazil. Siemens owns one-third of project company Gás Natural A?u (GNA) with Brazil logistics company Prumo Logística S.A. and oil major BP.

Siemens will benefit from the new study’s exploration of gas turbine compression trains in rolling systems. Its Houston-based Gas and Power unit produces products for power generation, such as gas and steam turbines, generators, turbine packages, and tailored OEM power plant solutions.

The new study will look into using gas turbine- and electric-driven compression trains in conjunction with proven single-mixed refrigerant and double-mixed refrigerant technologies for the coolant function in drivetrain and power systems. Another method being explored is developing techniques to improve the efficiency of onsite power generation facilities; that might include heat recovery systems, inlet air chilling, supplementary firing, renewables integration, and battery storage.

“Siemens Gas and Power is committed to supporting the LNG industry’s efforts to reduce carbon emissions through the application of proven equipment solutions and by providing financial, technical development, and strategic support to customers in the early concept development and pre-front-end engineering design (FEED) stages of projects,” said Thorbjoern Fors, CEO for Siemens Energy Oil & Gas Division. “We are proud to continue these efforts by partnering with Total to drive towards the lowest possible plant emissions profile and attain the highest degree of sustainability in LNG production.”

As part of the agreement, Siemens in conducting studies to explore possible liquefaction and power generation in plant designs. The endgame here will be hitting targets for decarbonizing LNG production. But other efficiencies are part of the overall goals, according to the two companies. That will include leveraging digitalization and automation platforms to optimize plant design and achieve seamless project execution.

Siemens thinks that application of digital technologies, such as artificial intelligence, digital twins, and predictive analytics, offer substantial gains for LNG developers and operators to improve the economic viability of their facilities. Participating in the Hammerfest LNG plant above the Arctic Circle, Siemens has been able to divert unplanned downtime in the plant. Siemens developed an advanced digital system that monitors and rapidly responds to the entire system to keep it operating efficiently.
