Title: Isoprene purification process
Inventor: HILL ARTHUR BENJAMIN
IPC: C07C7/00
Filed: 1965-10-18
Abstract: Isoprene is separated from a C5 hydrocarbon mixture by a straight distillation followed by two extraction distillations; in the straight distillation isopropylacetylene, dimethylacetylene, methylethylacetylene and pentadiene-1,4 are separated overhead, the bottoms are extractively distilled to separate C5 mono-olefins and the extract is extractively distilled in the presence of further solvent to separate isoprene as overhead from methylethylacetylene, cyclopentadiene, propylacetylene, piperylene and allylacetylene in the extract.  The solvent may be acetone or acetonitrile and may contain water.  The extract is preferably removed near the bottom of extractive distillation columns, the solvent separated and returned to the bottom of the extraction column and bottoms then recycled from the bottom to the top to supply the solvent.

Abstract: 969,246. Centrifugal separators. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov. 29, 1962 [Dec. 29, 1961], No. 46699/61. Heading B2P. The oxide and salt content of steam generated in a high-pressure boiler 1 is reduced by dividing the steam into two partial streams 15, 16, condensing the stream 16 in a heat exchanger 6 by means of feed water 11 as coolant, bringing the condensate 17 into contact with the stream 15 and leading the mixture into a centrifugal separator 8 where separation into purified steam 20 and water 22 takes place. The purified steam is led to a superheater 9 while the separated water 22 may be directed together with the feed water 11 via line 13 and tubes 14 to the steam drum 5. Alternatively, the separated water is passed through a preheater for combustion air before it is returned to the boiler. The mixer 7 in which the steam and condensed water are brought into contact may be in the form of an ejector or it may contain a liquid atomizer or it may be of the type described in Specification 953,597. Blow-down water 23 from the steam drum 5 is passed through a preheater 10 for combustion air 4 and may then pass through a water turbine driving feedwater pumps. The purified steam 20 may be split into two further streams and further purification is achieved by condensing, mixing and separation in a second centrifugal separator. Specifications 715,912 and 746,631 also are referred to.
