Abstract: A process  is  disclosed  for the removal of basic heterocyclic nitrogen compounds  from a petroleum crude oil or fraction thereof which comprises treating the petroleum crude oil in a distillation zone to form a distillation bottoms  stream which is rich in basic heterocyclic nitrogen compounds.   This  stream is passed without cooling or heat removal to a two-phase extraction zone with an extractant consisting essentially of an aqueous solution of a lower carboxylic acid and preferably having from 1 to 15 carbon atoms.  The extractant complexes the basic heterocyclic nitrogen compound to produce a stream of petroleum crude oil or fraction thereof having a smaller content of heterocyclic nitrogen compounds and a stream comprising the lower carboxylic acid extractant with an increased quantity of basic heterocyclic nitrogen compounds.  Both of these streams are passed to distillation without heating.  The stream of petroleum crude having the smaller  content  of  heterocyclic nitrogen compound is distilled into an overhead stream and a bottoms stream, the latter of which is hydrotreated to the product of this invention.  The stream comprising the higher nitrogen content is passed, without heating, to a distillation zone wherein a stream very high in nitrogen content is removed and an extractant recycle stream is recovered.  The extractant recycle stream is then recycled to the extraction zone.

Abstract: A powder-filled welded steel tube has a tube wall (1) with a welded longitudinal seam (6) and is wound into a coil for despatch. To reduce the risk that the seam opens when the tube is twisted, e.g. on uncoiling, the tube wall is provided with a continuous longitudinal groove (5). Preferably the groove (5) is symmetrical and directed radially inwards. In the continuous manufacture of such tube, a metal strip is formed into an open channel, powder is introduced into the channel, the channel is closed and the edges welded to form a closed tube. The diameter is then reduced and the finished product is coiled. The longitudinal groove (5) is rolled in continuously during the diameter reduction of the powder-filled welded tube.
