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.**

拟议的研究将侧重于消除液化天然气(LNG)输送、储存和分配作业中的逃逸排放。液化天然气可用作运输燃料，也可用于偏远地区的热电联产。我们将通过建立准稳态和随时间变化的热力学模型来研究输电、储存和配电操作。这些模型将使用来自我们合作伙伴现场仪器设备的数据进行验证(专门为支持拟议的研究而成立了一个工业联盟)。将应用计算流体力学(CFD)来模拟和最小化油罐-卡车-储罐运输过程中的热传递和逃逸排放。这些型号将包括加油站配备的储油罐和分配设备。最后，我们将把这些努力联系起来并加以转化，以优化液化天然气分销链和加油系统的设计。拟议的改进旨在减少或消除生甲烷的排放，同时简化操作和降低成本。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。**
