(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.
Commercial hexane contains a mixture of hexane isomers (n-hexane, 2-methyl pentane, 3-methyl pentane, 2,3-dimethylbutane), cyclohexane, methyl cyclopentane,pentane and heptane isomers The n-hexane content varies from 20 to 80%. (IPCS 1991)
