A numerical prediction model for the calculation of mercury partitioning in natural gas processing facility was considered and established as the technology to contribute proper handling of small amount of mercury in natural gas and oil. In the construction of the prediction model, at first, mercury solubility in natural gas components and chemicals which are used for gas processing was measured by lab experiment. Then, tuning of parameters in the prediction model based on equation of state was conducted by using measured mercury solubility data. As a result, it was found that the prediction model could properly reproduce mercury contents in the production process which mainly processes hydrocarbons.

[2E19] Evaluation of crude oil emulsion type and stability by electrokinetic properties

○Xingjuan Hao¹, Sadia Afrin¹, Mai Shimokawara², Yoshitake Kato², Ryuta Kitamura², Yogarajah Elakneswaran¹ (1. Hokkaido University, 2. Japan Oil, Gas and Metals National Corporation (JOGMEC))

The formation of crude oil emulsion is a complicated process with different types of transformation. In this study, the formation process of crude oil emulsion was divided into three stages. The type and stability of crude oil emulsion were investigated mainly based on electrokinetic property and resolved water. The effect of various brine conditions including pH, ion composition, and ionic strength on crude oil emulsion formation and stability was investigated. Moreover, the influence of crude oil properties especially total acid number/base number (TAN/TBN) ratio and asphaltenes content on emulsion formation and stability was evaluated.

[2E20] INPEX's biodiversity conservation activities

○Natsuki Kawaguchi¹, Shione Yamamoto¹, Wataru Nojiri¹, Naoto Sasaki¹ (1. INPEX Corporation)

石油・天然ガス事業活動は、生物多様性や地域コミュニティが依存する自然環境及び社会環境に影響を与える可能性がある。当社は、新規開発事業においては、環境・社会影響評価 (ESIA: Environment Social Impact Assessment) を通じて事業活動が生物多様性に及ぼす影響を予測・評価し、「負の影響」を低減するための対応策を策定・実行している。一方、既存事業においては、「正の影響」を創出するような取組みを検討・実行している。本講演では、当社の生物多様性保全の取組みについて紹介する。

[2E21] China and India's pathway to net-zero

○Mika Takehara¹ (1. Japan Oil, Gas and Metals National Corporation )

China and India are the world's largest consumers of coal and oil. In September 2020, Chinese President Xi Jinping declared that China aims to "peak its emissions before 2030 and become carbon neutrality by 2060".China is reducing coal and shifting to renewable energy. India is under pressure to set a net-zero target but is resisting it, as economic development and population growth will lead to higher energy consumption. It is expected to take a moderate approach to climate change while making efforts to transition to renewable energy.

[2E22] Considering climate change response of oil and natural gas industry toward decarbonized society

○Masaru Ihara¹ (1. JOGMEC)

気候変動を巡る欧米中を中心とした国際政治ゲームに呼応する形で、さまざまな研究機関で脱炭素に向けたシナリオが公表され大きな議論になっている。GHG排出削減に対するエネルギー転換や炭素制約のある未来戦略を考察し、抽出した内外の石油・天然ガス・エネルギー企業の気候変動対応を探り、2050年カーボンニュートラルの実現可能性を考える。
