    摘要: A valve is disposed in a line carrying an aqueous stream, the valve in the form of a permeable bed of particulate swellable polymer particles which imbibe organic materials and on contact therewith will swell to provide a positive shut-off and a polymeric structure which collapses on contact with organic liquid is disposed upstream of the permeable bed. Flow rates can be obtained which are higher than the flow rates with polymer particles alone.

    摘要: A package containing a hazardous liquid is provided. The package comprises a container which is generally impermeable to a hazardous liquid contained therein, the container being subject to discharge of its contents when subjected to impact. The container is disposed within a first jacket of a liquid permeable material of sufficient strength to contain fragments of the container on rupture thereof. A second jacket is provided over first jacket, the second jacket having at least an inner wall and outer wall, the inner wall being liquid permeable, a hazardous liquid swellable body being contained between the inner wall and outer wall and being generally co-extensive with the inner wall and the outer wall, and a third jacket of a hazardous liquid vapor impervious membrane. The package provides substantial improvement in safety when transporting a container containing a hazardous liquid.
