20090253940 | Method and Apparatus for Producing Purified Methyl Isobutyl Ketone - This invention relates to a method of producing purified methyl isobutyl ketone (MIBK) comprising subjecting a feed stream containing MIBK and impurities to a first distillation procedure from which acetone is recovered. The bottom product of the first distillation procedure is fed to a liquid-liquid separator and an organic phase from the said liquid-liquid separator is fed to the top region of a second distillation column to produce an overhead product. The said overhead product is condensed and fed to the said liquid-liquid separator. A bottom product containing MIBK is withdrawn from the second distillation column. This bottom product is fed to a third distillation column, high boiling impurities are withdrawn as a bottom product, and purified MIBK is also withdrawn. The invention also relates to an apparatus used in such a method. | 10-08-2009 |
20100222612 | Method and Apparatus for Producing Purified Methyl Isobutyl Ketone - This invention relates to a method of producing purified methyl isobutyl ketone (MIBK) comprising subjecting a feed stream containing MIBK and impurities to a first distillation procedure from which acetone is recovered and a bottom product containing MIBK and impurities is withdrawn. This bottom product is fed to a second distillation column, where a vapour overhead product is withdrawn, condensed and fed to an overhead liquid-liquid separator. Part of an organic phase from the overhead liquid-liquid separator is fed to the second distillation column and part is fed to a third distillation column. A vapour overhead product is withdrawn from the third column which is condensed in the same said condensor. The condensed product is fed to the same said overhead liquid-liquid separator, and purified MIBK is withdrawn from the third distillation column. This invention also relates to an apparatus used in such a method. | 09-02-2010 |

20110115166 | METHOD AND COMPOSITION FOR SEALING PASSAGES - A method of sealing a passage in a body with a sealing composition comprising (a) a major proportion of a latex emulsion or colloid; and (b) a minor proportion of lauric acid or a laurate compound; and (c) at least one further selected additive, ideally a latex coagulation inhibitor, wherein said composition is pumped into said passage where it is set or coagulated to form a seal. Advantageously, the laurate compound is ammonium laurate and coagulation is conveniently induced by adjusting pH of the sealing composition from alkaline to acidic pH range. The method is particularly well suited to sealing in faulty formations or sealing sites and may be used in sealing within salt mines which contain brines. | 05-19-2011 |

20150303662 | TRANSMISSION STATION FOR FEEDING IN ELECTRICAL ENERGY AND WIND FARM COMPRISING SUCH TRANSMISSION STATION - The invention relates to a transmission station for feeding locally provided electrical energy, in particular provided by one or more wind power installations, into a grid. According to the invention, it is proposed for a housing of the transmission station to feature a first, accessible room and a second room that is connected to the outside world by means of an exhaust pipe, with such first room and second room being connected to each other by means of a joint recess, with such control unit closing the joint recess, and with one casing of the control unit being open in the area where the recess is closed and/or showing a predetermined breaking point that is adapted to fail if an electric arc occurs inside the control unit. | 10-22-2015 |
