ENCLOSURE FOR A COLUMN FOR LOW-TEMPERATURE DISTILLATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240035746 titled 'ENCLOSURE FOR A COLUMN FOR LOW-TEMPERATURE DISTILLATION

Simplified Explanation

The abstract describes an enclosure for a low-temperature distillation column. The enclosure consists of a distillation column with a circular cross-section, which is thermally insulated. The column contains liquid during operation and is connected to at least one pipe for liquid transport. The column is enclosed in a sealed parallelepipedal casing, with pulverulent thermal insulation filling the space between the column and the casing. Below the column, there is a liquid-retaining tank with a flat bottom and four side walls, designed to collect leaked liquid. The tank is made from stainless steel or aluminum, while the casing is made from carbon steel. The column rests on the tank's bottom through a stainless steel cylinder skirt, and the liquid-retaining space also contains pulverulent thermal insulation.

  • The enclosure is designed for a low-temperature distillation column with a circular cross-section.
  • The column is thermally insulated and contains liquid during operation.
  • At least one pipe is attached to the column for liquid transport.
  • The column is enclosed in a sealed parallelepipedal casing.
  • Pulverulent thermal insulation fills the space between the column and the casing.
  • A liquid-retaining tank is placed below the column to collect leaked liquid.
  • The tank has a flat bottom and four side walls, defining a liquid-retaining space.
  • The tank is made from stainless steel or aluminum.
  • The casing is made from carbon steel.
  • The column rests on the tank's bottom through a stainless steel cylinder skirt.
  • Pulverulent thermal insulation is also present in the liquid-retaining space.

Potential applications of this technology:

  • Low-temperature distillation processes in industries such as chemical, pharmaceutical, and petrochemical.
  • Production of high-purity liquids or separation of different components in a liquid mixture.

Problems solved by this technology:

  • Thermal insulation of the distillation column to maintain low temperatures.
  • Collection of leaked liquid to prevent loss and potential contamination.
  • Sealing of the enclosure to prevent heat exchange with the surroundings.

Benefits of this technology:

  • Improved energy efficiency by minimizing heat loss during distillation.
  • Enhanced product quality by maintaining low temperatures and preventing contamination.
  • Increased safety by collecting leaked liquid and preventing environmental hazards.


Original Abstract Submitted

an enclosure for a column for low-temperature distillation comprises a distillation column, which has a circular cross section and is to be thermally insulated, the column containing liquid during use, at least one pipe attached to the column for transporting a liquid, a parallelepipedal casing enclosing the column in a sealed manner, pulverulent thermal insulation filling the space between the column or columns and the casing, a liquid-retaining tank, which has a flat bottom and four side walls, defining a liquid-retaining space, the tank being arranged inside the casing below the column in order to collect liquid that has leaked from the column, the tank being made from stainless steel or from aluminium and the casing being made from carbon steel, the column resting on the bottom of the tank through a skirt, the skirt being a cylinder made from stainless steel and having the same diameter as the column, the liquid-retaining space containing pulverulent thermal insulation.
