Book Description
Excerpt from Distillation of Resinous Wood by Saturated Steam Table 3 gives the conditions of the distillations and the results obtained. Under Size of chip the length parallel to the grain is given first. The probable error in the determinations of yields is apparently.' about 7 per cent and is due to difficulties in sampling, in regulating evaporation during the preparation of material, and in Obtaining comparable end points in different distillations. An exam; ple of results which must be due to such errors is seen in runs 23 and 24. The chips ln 1un 24 are larger than those in run 23, and the yield probably should be less, and certainly not greater, from the larger chips; yet the yields obtained from run 23 are 5 per cent less than those 110111 run 24. A similar example IS shown 1n runs 30 and 31. It might be thought that some of these variations in yields were due to incomplete distillation caused by the steam channeling through the charge ln such a way that it never touched part of the wood; but in several runs, after all possible 011 had been distilled under one set of conditions, the top of the retort was removed, the charge was well stirred, and the d1stillation continued under the same conditions as before, without any indications that the stirring had discovered undis tilled material. It seems probable, therefore, that with a retort of the shape and size used the effect of incomplete distillation clue to incomplete contact between the steam and the chips is negligible.
