A thermoelectric generator includes a thermoelectric module and a micro heat exchanger. The thermoelectric module includes p- and n-conducting thermoelectric material pieces which are alternately connected to one another via electrically conductive contacts. The thermoelectric module is thermally conductively connected to a micro heat exchanger. The micro heat exchanger includes a plurality of continuous channels having a diameter of at most 1 mm, through which a fluid heat exchanger medium can flow.

Thermoelectric modules for an exhaust system

A process for preparing pure triethanolamine (TEOA) by continuously distillatively separating an ethanolamine mixture comprising TEOA and diethanolamine (DEOA), by distilling off DEOA in a distillation column (DEOA column) and supplying the resulting bottom stream comprising TEOA to a downstream column (TEOA column) in which the pure TEOA is withdrawn as a side draw stream, wherein the residence time of the ethanolamine mixture in the bottom of the DEOA column is &#x3c;20 minutes.
