    摘要: A method of treating gas containing water in order to remove at least part of the water from the gas, including feeding the natural gas to be treated by a first line, with a liquid fraction containing at least an aqueous phase is fed via a second line in the presence of a solvent into a contact zone, so as to bring the gas into direct contact with the liquid fraction over at least a portion of the contact zone. The solvent is a non-hydrocarbon compound other than water, and simultaneously, the gas is cooled in the presence of the solvent in order to condense at least one liquid phase consisting essentially of water in a mixture with the solvent. The non-condensed gaseous phase is separated from the condensed liquid phase, from which the solvent has essentially been removed

    摘要: The present invention presents an antigenic peptide whose amino acid sequence comprises a fragment of the caseinomacropeptide (CMP) sequence, which peptide is characterized in that it carries at least one epitope of CMP. These peptides exhibit no or little cross-reactivity with K-casein. When these peptides are used as immunogens, they make it possible to obtain specific anti-CMP antibodies. Also disclosed is a process for detecting the presence of cow's milk CMP in milk and milk products, using the above antibodies. Further presented are diagnostic reagents for the assay of CMP, which reagents are characterized in that they comprise at least one peptide, antigenic composition, or anti-CMP antibody of the present invention.

    摘要: A process for simultaneously exchanging material and for exchanging heat, material change being effected between a gas phase and at least one liquid phase by contact and passage in opposite directions of the gas phase and of the at least one liquid phase and heat exchange being effected between a compartment (I) and another compartment (II). In compartment (I) a plurality of spacer plates defining material exchange passages are arranged and the material exchange is effected by causing the at least one liquid phase to flow over a substantially vertical or inclined wall of a corrugated spacer plate having perforations and by causing at least a fraction of the gas phase to traverse simultaneously said perforations in a substantially ascending direction to contact said at least one liquid phase. The heat exchange is effected by circulating a heat exchange fluid in the compartment (II) which has a common wall with the compartment (I).

    摘要: A method and device for separating a continuous phase from at least one dispersed phase, with the phases having different densities. A mixture of the phases to be separated is supplied into a device including at least one cylindrical chamber vertically disposed and at least one static helically-shaped member is accommodated in the chamber. At least one face of the helically-shaped member is formed by a helicoidal surface. A maximum free path of a dispersed phase particle in a radial direction prior to colliding with the helically-shaped member is less than one quarter of a peripheral diameter of the member and, preferably, less than one tenth of an internal diameter of the chamber. The method and apparatus are capable of separating an aqueous phase from an organic phase such as, a petroleum fluid, with the mixture to be separated also possibly including a gaseous phase and a solid phase.
