Fugitive emissions in liquefied natural gas transmission, storage, and distribution: Canadian solutions for transportation and remote power generation

拟议的研究将侧重于消除液化天然气（LNG）传输、储存和分销业务中的逸散排放。液化天然气可以用作运输燃料，也可以用于偏远地区的热电联产。我们将通过建立准稳态和时间相关的热力学模型来研究传输、存储和分配操作。这些模型将使用来自我们合作伙伴现场的仪器和现场设备的数据进行验证（已经专门创建了一个工业联盟来支持拟议的研究）。计算流体动力学（CFD）将应用于模拟和最小化油罐车到储罐运输过程中的传热和逸散排放。这些模型将包括储罐和配药设备的特点，在加油站。最后，我们将把这些努力联系起来并转化为优化液化天然气分销链和加油系统的设计。提出的改进措施旨在减少或消除原料甲烷的排放，同时简化操作并降低成本。预期的研究突破可以立即转移给我们的财团合作伙伴，从而提高加拿大天然气行业的安全性和竞争力。

The proposed research will be focused on eliminating fugitive emissions from liquefied natural gas (LNG) transmission, storage, and distribution operations. LNG can be used as fuel for transportation, and for combined heat and power generation in remote locations. We will study transmission, storage, and distribution operations by developing quasi-steady-state and time-dependent thermodynamic models. These models will be validated using data from instrumented, field equipment at our partners' sites (an industrial consortium has been created specifically to support the proposed research). Computational fluid dynamics (CFD) will be applied to simulate and minimize heat transfer and fugitive emissions in tanker-truck to storage-tank transfers. These models will incorporate the storage tanks and dispensing equipment featured at refueling stations. Finally, we will link and translate these efforts to optimise the design of LNG distribution chains and refueling systems. The proposed improvements aim to reduce or eliminate venting of raw methane while simplifying operations and reducing costs. The expected research breakthroughs can be transferred to our consortium partners immediately - thereby enhancing the safety and competitiveness of Canada's natural gas sector.
