摘要： The present invention provides a process for recovering ditrimethylolpropane from a still residue obtained by extracting and then distilling off trimethylolpropane from a reaction solution obtained by reacting n-butyraldelhyde with formaldehyde in the presence of a basic catalyst, wherein the still residue is distilled to remove high-boiling components therefrom, and the resultant distillate is subjected to crystallization. When the above process is combined with the acid decomposition, it becomes possible to decompose a linear formal compound obtained from 2 molecules of TMP contained in the still residue as crude TMP and one molecule of formaldehyde, so that di-TMP having a higher purity is obtained.

摘要： A mechanical water still (10) includes an impervious dome-like upper surface (12) and a membrane base (14) that is coupled (26) to the impervious dome-like structure (12) to form, when inflated, a chamber (20). The membrane base (14) supports a water pervaporation process therethrough. A water collection well (16) has an opening into which water droplets condensed from the water pervaporation process collect. The water collection well (16) is sited within the membrane base (14) and generally extends outwardly and downwardly from the membrane base (14), as shown in FIG. 1. In use, a contaminated water source (24) is brought into, ideally, complete contact with the membrane base (14), with the water collection well (16) arranged both to act as a heat sink into the water source (24) and to provide stability to the water still (10) when floating and immersed in the water source (24).

摘要： A system and method of forming a mixture from two elements according to which the elements are introduced into a vessel and mixed in the vessel before being discharged from the vessel. The flow rate of one of the elements is controlled to maintain a constant level of the mixture in the vessel and the flow rate of the other element is controlled to maintain a predetermined ratio of the flow rate of the latter element and the discharge flow rate.
