High pressure calorimeter

该提案要求获得资金以获得高压量热计。高压（高达20mpa）下的量热法提供了一种独特的能力，可以获得与各种应用相关的过程和系统的热力学性质。近年来，高压量热法已成为研究天然气水合物相变的一种非常有用的工具。例如，我们可以得到在水合物抑制化学物质存在下天然气水合物的熔化曲线。这些曲线告诉我们发生相变的确切条件。这些信息对于设计安全和经济的石油和天然气运输设施是有用的。我们也可以研究类似于地球上自然存在的水合物或人工水合物的行为。这些信息有助于扩大从地球水合物中提取天然气的过程。

This proposal requests funds to obtain a high pressure calorimeter. Calorimetry under high pressure (up to 20 MPa) offers a unique ability to obtain thermodynamic properties for processes and systems relevant to a variety of applications. In recent years, high pressure calorimetry has become an extremely useful tool to study gas hydrate phase transitions. For example, we may obtain melting curves of gas hydrates in the presence of hydrate inhibiting chemicals. These curves inform about the exact conditions where the phase transition occurs. This information is useful in the design of safe and economic facilities for the transport of oil and gas. We may also study the behaviour of naturally occurring or artificial hydrates resembling those that occur naturally in the earth. This information, aids the scale up of processes considered to extract natural gas from the earth's hydrates.
