  "abstract": "The present invention relates to an insertion device for inserting at least one packing section for a gas/liquid separation column into a cylindrical casing, comprising a base provided with retaining means which are configured to grip a packing section and which are arranged uniformly around a main axis, characterized in that the insertion device comprises at least two fastening means secured to the base, said fastening means being configured to fasten the insertion device to the casing. The invention also covers an insertion system for inserting at least one packing section into a cylindrical casing, comprising such an insertion device, and a method for inserting at least one packing section into a cylindrical casing that is implemented by such an insertion system.",
  "claims": [
    "1. An insertion device for inserting at least one packing section for a gas/liquid separation column into a cylindrical casing, the insertion device comprising: a base provided with retaining means which are configured to grip a packing section and which are arranged uniformly around a main axis; at least two fastening means secured to the base, said fastening means being configured to fasten the insertion device to the casing.",
    "2. The insertion device according to claim 1, wherein the fastening means are arranged uniformly around the main axis.",
    "3. The insertion device according to claim 1, wherein at least one fastening means and one retaining means are arranged on one and the same peripheral member of the base.",
    "4. The insertion device according to claim 1, wherein the fastening means each comprise a retractable cylinder, a hook and a drive assembly mechanically connecting the retractable cylinder to the hook.",
    "5. The insertion device according to claim 1, wherein the drive assembly comprises at least one connecting rod and a crank which are configured to drive a pivoting movement of the hook according to a linear movement of the retractable cylinder.",
    "6. The insertion device according to claim 5, wherein the hooks are able to pivot between a retracted position and a deployed position.",
    "7. The insertion device according to claim 1, wherein the hooks in the retracted position are set back from the retaining means with respect to the main axis.",
    "8. The insertion device according to claim 7, wherein at least one fastening means and one retaining means are arranged on one and the same peripheral member of the base, wherein the pivoting movement of the hooks takes place at a face of the peripheral member that is opposed to the retaining means.",
    "9. An insertion system for inserting at least one packing section for a gas/liquid separation column into a cylindrical casing, the insertion system comprising: a bearing structure; and an insertion device according to claim 1, the insertion device being borne by the bearing structure in such a way that the fastening means are configured to fasten the insertion device to the casing.",
    "10. The insertion system according to claim 9, wherein the insertion device is configured in its entirety to carry out a translational movement relative to the bearing structure.",
    "11. The insertion system according to claim 9, wherein the insertion device is configured in its entirety to carry out a rotation relative to the bearing structure.",
    "12. A method for inserting at least one packing section for a gas/liquid separation column into a cylindrical casing that is implemented by an insertion system according to the preceding claim, the method comprising: gripping a packing section by the retaining means of the insertion device; rotating the insertion device in its entirety with respect to the bearing structure; moving the insertion system up to the casing by means of the bearing structure; positioning the packing section at an inlet of the casing; fastening the insertion device to the casing using the fastening means; and pushing the packing section into the casing."

  "description_excerpt": "The present invention relates to the field of gas/liquid separation columns and to their assembly, and it more particularly concerns a device for inserting packing sections into a casing in order to form said gas/liquid separation columns.\n\nGas/liquid separation columns have been known for many years and make it possible, for example, to carry out a separation of various chemical elements involved in the composition of a homogeneous fluid, for example by distillation or by absorption.\n\nThe manufacture of a gas/liquid separation column comprises in particular a step of inserting a plurality of packing sections for a gas/liquid separation column into a casing. The packing sections are particularly used in the columns to ensure the exchange of material and of heat between a rising gas and a descending liquid. These packing sections, which consist, in particular, of several superposed corrugated strips, are often referred to as “packs”. The packing sections are conventionally stacked on each other, possibly with interposed separators, in order to help separate the components of the fluid along the axial dimension of the column.\n\nJP H01 242102 describes a device for inserting at least one packing section into a cylindrical casing, comprising a base provided with retaining means which are configured to grip a packing section and which are arranged uniformly around a main axis.\n\nIt is known for packing sections to be inserted into a vertically held casing, the force of gravity greatly facilitating the progression of the packing section inserted into the casing.",
