(7) From (8), it is evident that an error is induced at every time-step due to the truncation of the Taylor series, this is referred to as the local truncation error (LTE) of the method. For the forward Euler method, the LTE is O(h2). Hence, the method is referred to as a first order technique.
Abstract. An integrated thermal recovery process using a solvent of a pentane or hexane or both as an additive to, or sole component of, a gravity-dominated process for recovering bitumen or heavy oil from a reservoir. A pentane-hexane specific solvent fraction is extracted at surface from a diluent stream.
Pentane is more volatile than heptane so there will be more pentane in the vapor mixture. Remember, on these plots we are using x to represent the mole fraction of n-pentane (the more volatile component) and 1- x to represent the mole fraction of n-heptane in the liquid.
