Basic terms in air separation: Rectification column – a tower used for the fractional distillation of multi-component mixtures. A cryogenic rectification column is a tower that carries out the rectification process at low temperatures, thereby separating liquid air into components such as oxygen and nitrogen. A single rectification column is a column that performs one stage of rectification; it is a device consisting of a column and a condenser-evaporator. A double rectification column is a tower used for secondary distillation; it is a device composed of a lower column, an upper column, and a condensation evaporator. The lower column is the tower in two-stage distillation where air is initially separated. The upper column is the column in two-stage distillation where air undergoes final distillation. Oxygen column: a distillation tower used to produce high-purity oxygen. Nitrogen column: a distillation tower used to produce high-purity nitrogen. A sieve-tray column (perforated tray column) is a type of column that contains tray plates with sieve holes; rising steam passes through these holes to come into contact with the liquid, allowing for mass and heat transfer between the gas and liquid phases. A bubble cap tray column is a type of column equipped with bubble cap trays; rising steam passes through the gaps between the bubble caps to come into contact with the liquid, enabling mass and heat transfer between the gas and liquid phases. A packed column is a tower in which packing is filled inside; it is a type of tower where mass and heat transfer occur through the packing. The rectifying section is the part of a distillation column used to continuously increase the concentration of the low-boiling-point components. The stripping section is the section of a distillation column used to continuously increase the concentration of high-boiling-point components. A tray facilitates mass and heat transfer between the gas and liquid phases, thereby enabling the separation of the components in the gas-liquid mixture. Circular flow tray: A tray in which the liquid flows circumferentially into the overflow trough. Counter flow tray: A tray in which the liquid flows into the overflow channel in opposite directions. A bubble cap tray is a tray with numerous bubbles arranged in an orderly pattern. A sieve tray is a tower tray covered uniformly with small holes. An overflow downcomer is a channel that allows liquid to flow from one tray to the next in a tower. Single overflow: there is only one liquid flow channel per tray. Double overflow: there are two overflow channels on each tray. Multi-overflow: Each tray has two overflow channels. An overflow weir is a device used to maintain a certain height of liquid layer on the tray; a baffle is placed before the liquid flows from the tray into the overflow channel, and this baffle is known as the overflow weir. Packing increases the contact area between the gas and liquid phases, enabling mass and heat transfer in order to separate the components of the gas-liquid mixture. A heat exchanger is a device used to facilitate heat exchange between two fluids, one hot and the other cold. A plate-fin heat exchanger is composed of basic components such as partition seals, fins, and flow guide vanes, which are stacked and arranged in various ways to be brazed together into a single unit (the plate bundle), with end caps and connections installed at the fluid inlet and outlet. The plate bundle core is composed of basic elements such as partitions, seals, fins, and guide vanes, which are stacked and arranged in different ways to be brazed together into a single unit. Partition plate: a metal plate located between two flow channels, also known as the primary heat transfer surface. The seal strip side bar is a metal strip placed on both sides (ends) of each channel fin for sealing purposes. A fin is a secondary surface used for heat exchange between hot and cold fluids. A plain fin is a type of fin made from thin metal sheets, featuring a smooth rectangular cross-section channel. Perforated fin: a flat fin with holes punched in it. 3.8 Perforated fin: a flat fin that features holes drilled through it. Serrated fin: a type of fin in which the fins are cut and bent at regular intervals, causing the flow channels to be offset from each other. Corrugated fin: a type of fin that is stamped into a wavy shape. A distributing fin is a type of large-pitch porous fin that evenly directs the fluid to the flow channels of the fins or collects it within the head. A plate-fin type reversing heat exchanger is a device in which air and contaminated nitrogen gas are alternately used for heat exchange, thereby removing moisture and carbon dioxide impurities from the air. The warm section of a plate-fin type reversing heat exchanger refers to the part of such a heat exchanger unit that is separated from the other part by the outlet for recirculating air; the section with higher temperatures is known as the warm section. The cold section of a plate-fin type reversing heat exchanger refers to the portion of such a heat exchanger unit that is separated from the other part by the outlet for recirculating air; the section with lower temperatures is known as the cold section. Main heat exchanger: The primary heat exchanger in air separation units, used to recover the cooling capacity of the product gas in order to cool the feed air. A tubular heat exchanger is a type of heat exchanger in which heat is transferred between two fluids, hot and cold, through the tube walls. A shell and tube heat exchanger is a type of tubular heat exchanger that consists of many tubes arranged in series and fixed to upper and lower parallel tube sheets; the tube bundle is placed inside a cylindrical shell. One of the fluids flows inside the tube, while the other flows between the tubes. A coiled pipe heat exchanger is a type of tubular heat exchanger in which several tubes fixed at both ends to tube sheets are wound in layers around a central tube; spacers are placed between each layer of coils (the thickness of these spacers determines the gap between the tubes, which forms the air flow channels), and the coil bundle is in close contact with the outer tube. One fluid flows within the tube, while the other fluid flows between the layers of the coil. A subcooler is a heat exchanger that further cools saturated liquid without causing a phase change. A liquid air subcooler is a heat exchanger that further cools the oxygen-enriched liquid air at its saturation temperature without causing any phase change.

A liquefier is a heat exchanger that converts gases into liquids. An oxygen/air liquefier is a heat exchanger that utilizes the air from the lower tower to recover the cooling capacity of the nitrogen gas returning back, thereby liquefying the air. A pure nitrogen/air liquefier is a heat exchanger that utilizes the air coming from the lower column to recover the cooling capacity of the reflux oxygen, thereby liquefying the air. A waste nitrogen/air liquefier is a heat exchanger that utilizes the air coming from the lower tower to recover the cooling capacity of the returning waste nitrogen gas, thereby liquefying the air. A condenser is a heat exchanger that converts steam into liquid. A vaporizer is a heat exchanger that converts liquid into gas. A condenser/evaporator is a heat exchanger that provides reflux liquid and rising vapor to a distillation column, along with facilitating changes in the phase state of the fluids. A liquid jet evaporator is a device that uses steam to directly heat the liquid being discharged, causing it to vaporize rapidly. A cooler is a heat exchanger that typically uses water or air as a coolant to cool liquids. A precooler is a heat exchanger that uses the cooling capacity of the returning gas or external cooling to pre-cool the feed air. A regenerator is a type of regenerative heat exchanger in which heat exchange takes place between hot and cold fluids through a packing as an intermediate medium; it is also used to remove moisture and carbon dioxide from the air, operating in a periodic alternating manner. A filter is a device used to remove solid particles and oil mist from liquids or gases. An air filter is a device that uses mechanical methods to filter solid particles out of the air. A dry band filter is a device that uses plush fabrics woven from nylon fibers or fibers such as cotton and wool to filter dust and oil mist contained in the air. A chain filter is a filtration device in which the dust contained in the air gets attached to the oil film on the mesh as it passes through; as the chain rotates, the dust that has attached becomes washed away as it passes through the oil tank, and a new layer of oil film is applied. A bag filter is a device that uses bag filters to remove dust and oil mist contained in the air. A Raschig ring filter is a device for filtering solid particles from gases, consisting of an insertion box containing Raschig rings inside a steel housing; these rings are coated with a filtering oil with a low freezing point.
