测量,甲烷下降:创新耀斑管理

April 28, 2021

Flare Stacks,那些从炼油厂,液化天然气,海上平台,化学和石化工厂戳出的可识别的火焰状管,表现出必不可少的安全角色任务。

They are an essential safety device to safely dispose of gas if another part of the facility has to be shut down suddenly. It is often methane-heavy vent gas, and methane packs a potent punch as it’s estimated to have at least 25 times the warming potential of carbon dioxide over a 100-year period.

Operators and regulators recognize the importance of achieving high combustion efficiency (CE) of flare gas in order to reduce these methane emissions. When properly burnt off, the gas converts to carbon dioxide and prevents raw methane from entering the atmosphere via the flare stack.

“对于我们境外的许多生产网站,我们的境外业务外,狂欢是甲烷的最大来源,”伦敦的环境科学家来自BP的彼得埃文斯表示,寻找更好的测量甲烷方法。“人们担心[天然气]泄漏,但在现实中,泄漏往往是涉及排放的小部件。提高耀斑上测量的准确性提供了更高的甲烷减少潜力。“

There’s a lot to measure: satellite data was used to estimate that1500亿吨of gas was flared by the industry in 2020, the highest level since 2009.

There are other significant contributors to methane in the atmosphere, including agriculture and landfill. But, says Evans, “We in the oil and gas sector can address the methane emissions that come from our operations because they are focused and localized in ways that they may not be for other industries.”

BP的野心是2050年或更快的净零公司,也是支持他人也可以到达那里。这项野心得到了10个目标,包括目标4.: “To install methane measurement at all our existing major oil and gas processing sites by 2023, publish the data, and then drive a 50% reduction in methane intensity of our operations”.

As part of that plan, BP is usingflare.iq.为了帮助更好地理解,衡量和最终降低甲烷排放。它是由巴格纳米特人,Baker Hughes公司开发的先进的耀斑控制和数字验证平台,以及该公司广泛的排放管理能力。亚博竞彩AppFLARE.IQ解决方案坐落在工厂的控制系统上,不断测量排放并提供实时数据,以便操作员可以确保耀斑在目标98%CE处运行。

Flare.IQ技术最初是为了帮助石油和天然气炼油厂符合美国的环保署规定。“例如,EPA要求您每15分钟监控您的爆发,以便符合符合要求,”埃文斯解释说。“FLARE.IQ等技术,服务价值链的一部分和那些类型的耀斑。”

大约两年前,埃文斯和他的团队开始的助教lking with Baker Hughes about BP’s ambitions around methane measurement and if flare.IQ could have value for upstream production facilities.

两家公司开始共同努力,并在2020年举行第一次试验,通过一些关于合作的横向思考来迅速部署。首先,埃文斯解释说,他们试图弄清楚如何对炼油厂控制系统进行物理适应。“我们正在努力升级技术挑战,了解如何升级硬件以测试这一新软件,”他说。

他的一个BP同事指出,他们需要运行计算所需的所有数据都已经流入云中。为什么他们不能抓住那个数据,将其处理到其他地方,然后将其归还给设施?埃文斯说,“使用云计算的力量使它成为一个更简单的部署 - 在很多网站上,我们可能永远不必访问安装flare.iq。这有点像在手机上下载一个新的应用程序 - 你不必去高街上的电话商店去做。“

“使用云计算的力量使其成为一个更简单的部署。”

The power of flare.IQ is that it takes real-time measurements and instantly turns them into information, so that operators can quickly tweak their combustion process if they need to improve their CE.

“这是一系列计算模型,将原始数据转化为在展示美国甲烷强度方面的输出,”埃文斯说,即地球化学博士学位,在技术管理中,埃文斯说,埃文斯说。“它为我们提供了关于耀斑的性能的实时数据,我们可以看出它是否没有达到我们需要它的标准。”

Flare.IQ的第一个试验网站是在北大西洋运营的FPSO(浮动生产储存和卸载)设施。对于就职为期六天试验,BP使用船舶现有的控制系统“从流量计中获取所有信息,运行FLARE.IQ算法并提供实时反馈,”埃文斯解释说。

数据显示出始终如一的燃烧性能标准,高于99%,符合其设计的方式。埃文斯说,Flare.IQ给BP的是绝对的验证。“船上的运营商对船只的信心充满信心,因为他们从Flare.iq获得了这一反馈时,他们可以看到耀斑的表现。如果有性能发生变化,因为组件需要维护,或者环境条件在耀斑上施加额外的压力,他们可以采取行动并在那里进行任何必要的干预措施。“

埃文斯说,埃文斯说,它全部交付,“通过先进的分析,而无需对耀斑建造或运营的方式进行广泛的变化,并且它还没有要求服务工程师出门并物理地改变系统上的任何内容”。

The value of swift, low-touch deployment to BP’s sustainability targets is immense. “It means it’s something we can adopt rapidly, and that matters,” he says. “We have to bring our emissions down while maintaining operational productivity to keep global supplies of energy where they need to be. The ability to use data that’s already in our systems is an important message beyond this technique … there’s a lot of things we can do with that data at a level of sophistication that historically we may not have done.”

耀斑。智商是罗尔d out to more BP facilities, Evans is excited about the potential. “The more you deploy, the more you learn,” he says. “There’s no such thing as too much data and the more we learn, the more we can understand the algorithms better, refine our systems and demonstrate the average efficiencies on a global basis of our flares as part of our reported values.”

同时,FLARE.IQ平台的能力也在增长。“在最新版本中,我们能够进行耀斑效率的远程验证,这意味着没有人力,没有基础设施,无需占用米,”巴克休斯的巴格纳格州巴格纳姆的副总裁Diadmaid Mulholland说。亚博竞彩App它是“启动立即行动......帮助那些经营耀斑的人快速采取有意义的行动。这是一个非常令人兴奋的空间,我们可以带来真正对环境影响的实际效率。例如,如果我们采取以70%的耀斑效率运行的设施,部署Flare.iq将实现98%+效率 - 排放量相当于从我们的道路上移除约34,000辆汽车。“

Evans is rightly proud of BP’s efforts to reduce methane emissions and says that industry as a whole is running ahead of regulations.

“Normally regulations are created first, and then industry works to meet those regulations,” he says. “BP and other resources companies, trade associations and other bodies that have been created, all recognize how important it is to reduce methane emissions to help address climate change. We are making commitments to our stakeholders and shareholders that are informing the regulators, who are only now starting to embody it in law. The order in which these things play out has actually switched, and the industry is moving faster than the regulators are.”
