据世界天然气2月2日消息称，石油和天然气服务提供商贝克休斯与俄罗斯诺瓦泰克签署了一项协议，以减少后者天然气和液化天然气生产中的碳排放。
两家公司将合作开发和实施贝克休斯为诺瓦泰克LNG项目提供的创新压缩和发电技术解决方案。
贝克休斯在声明中表示，该协议将从一个试点项目开始，在天然气液化的主要工艺中引入混合氢，以减少包括诺瓦泰克的亚马尔液化天然气设施在内的液化天然气设施的二氧化碳排放。
贝克休斯将提供工程和涡轮机械设备，将亚马尔液化天然气现有的天然气液化生产线改造为使用混合氢，而不是仅仅使用原料气中的甲烷。
诺瓦泰克董事长Leonid Mikhelson表示：“氢技术在降低全球温室气体排放水平方面前景广阔，需要进一步开发和改进这些技术，以适应北极气候条件下的作业。”
贝克休斯董事长兼首席执行官Lorenzo Simonelli补充说：“我们正与诺瓦泰克公司合作，推出首款液化天然气生产核心脱碳解决方案——涡轮驱动液化过程。”
俄罗斯最大的独立天然气生产商诺瓦泰克每年的产量超过770亿立方米，每年约90亿立方米销往国际市场。
位于西伯利亚北极海岸的由三条生产线组成的Yamal LNG项目于2017年运输了第一批LNG货物，并于2018年达到其目前设计的满负荷生产能力。
混合氢为天然气行业减少液化天然气涡轮机械设备(液化过程的主要机械驱动设备)的排放提供了重大机遇。

Baker Hughes, Novatek in LNG production decarbonization pact
Oil and gas service provider Baker Hughes has signed a deal with Russia’s Novatek to reduce carbon emissions from the latter’s natural gas and LNG production.
The two companies will cooperate on the development and implementation of innovative compression and power generation technology solutions from Baker Hughes for Novatek’s LNG projects.
The agreement will begin with a pilot program to introduce hydrogen blends into the main process for natural gas liquefaction to reduce carbon dioxide emissions from LNG facilities, including Novatek’s Yamal LNG complex, Baker Hughes said in its statement.
Baker Hughes will provide engineering and turbomachinery equipment to convert existing natural gas liquefaction trains at Yamal LNG to run on hydrogen blends rather than solely run with methane from feed gas.
Leonid Mikhelson, Novatek’s chairman said, “Hydrogen technologies have great prospects to reduce the level of global greenhouse gas emissions, and further work is required to develop and adapt these technologies for operations in Arctic climatic conditions.”
Lorenzo Simonelli, chairman and CEO, Baker Hughes added, “We are working with Novatek to introduce the first solution for decarbonizing the core of the LNG production – the turbines driving the liquefaction process,”
Novate, Russia’s largest independent natural gas producer, delivers more than 77 billion cubic meters per year (bcm/yr) with about 9 bcm/yr of LNG sold in international markets.
The three-train Yamal LNG project, located on the Siberian Arctic coast, shipped its first LNG cargo in 2017 and reached full capacity under its current design in 2018.
Hydrogen blends present significant opportunities for the natural gas sector to cut emissions for LNG turbomachinery equipment, the main mechanical driver of the liquefaction process.
