Description
本発明の別の利点および特徴は、添付の図面を参照して考慮されるとき、以下の発明を実施するための形態から明らかになるであろう。
指標特性=f(密度crude oil,FTIRIcrudeoil)(2);
指標特性=K+X1*DEN+X2*DEN2+X3*DEN3+X4*FTIRI+
X5*FTIRI2+X6*FTIRI3+X7*DEN*FTIRI(3);
式中:
DEN=原油サンプルの密度;および
K、X1〜X7は、FTIRからの炭化水素データの線形回帰分析を用いて得られる、予測される特性の定数である。
FTIRI=[maxtransAM]−[maxtransの最小値]の通り計算した。したがって、原油AMのFTIRIは、[108.797]−[94.935]=13.862である。
