中文摘要 | 液化天然氣成份分析為換算熱值之主要參考依據。並可提供發電廠核算 發電效率,燃料處確保採購品質所仰賴之精確分析。 本試驗技術的建立除根據ASTM,GPA之相關規範外,並參考中油公司永安液化 天然氣廠與海外廠商所簽訂的分析技術規範。本文介紹內容包括:液化天然氣的 採樣方法、利用氣體層析法分析天然氣的程序、以及台電方面與中油公司永安廠 化驗室會同採樣進行實驗室間比對分析。比對結果符合相關規範之重覆性與再現 性之規定,確認本試驗室對液化天然氣之成份分析能力已達相當之水準。 |
英文摘要 | The component analysis is an essnetial base for calculatingthe heating value of liquified nature gas(LNG). This analysisensures the quality of purchased LNG, and also assists thepower plant of Taipower to calculate its efficiency. In addition to following the related specifications ofASTM and GPA, We also refer the technique to the methodspecified on the purchasing contract between China PetroleumCompany(CPC) and its LNG supplier from abroad. This article introduces the sampling method of LNG, theprocedure of analyzing LNG by using gas chromatography(GC), and comparision of the test results with that performed by the Yung An LNG plant of CPC. From the repeatibilityand reproducibility of test results, it proves that our analysistechnique has fulfilled the related standard requirements. |
