Degassing, also known as degasification, is the removal of dissolved gases from liquids, especially water or aqueous solutions. There are numerous methods for removing gases from liquids. There are numerous methods for removing gases from liquids.
[2] [3] For example, before casting aluminium alloys, argon bubbles are injected into liquid aluminium using a rotary degasser. The argon bubbles rise to the surface, bringing with them some of the dissolved hydrogen. The degassing step reduces the occurrence of hydrogen gas porosity. In the steel making process, this method is used very ...
Compared savings from dynamic degassing over reboiler degassing. In the case of a traditional base load power plant, cycling is much less frequent—in some cases, only twice annually for maintenance. Compared with measuring only cation conductivity, the cost savings from an accelerated start-up using degas conductivity is potentially very large.
Random column packing is the practice of packing a distillation column with randomly fitting filtration material in order to optimize surface area over which reactants can interact while minimizing the complexity of construction of such columns. Random column packing is an alternative to structured column packing.
For example, at ambient temperature and pressure and considering air and water as working fluids, a bubble column is classified as a large-diameter if it has a hydraulic diameter greater than 0.15 m. [3] Due to the very high gas velocity, the annular flow regime is not usually observed in industrial bubble columns.
The amount of heat entering the column from the reboiler and with the feed must equal the amount heat removed by the overhead condenser and with the products. The heat entering a distillation column is a crucial operating parameter, addition of excess or insufficient heat to the column can lead to foaming, weeping, entrainment, or flooding.
Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for example antibiotics, citric acid, vitamin E, and insulin.
For example, the measurement of product conductivity is a typical way to monitor and continuously trend the performance of water purification systems. The electrolytic conductivity of ultra-high purity water increases as a function of temperature ( T ) due to the higher dissociation of H 2 O in H + and OH − with T .
