An example process flow diagram for this system. Lean, water-free glycol (purity >99%) is fed to the top of an absorber (also known as a "glycol contactor") where it is contacted with the wet natural gas stream. The glycol removes water from the natural gas by physical absorption and is carried out the bottom of the column.
The desiccant helps to prevent the condensation of moisture between the panes. Another use of zeolites is in the "dryer" component of refrigeration systems to absorb water carried by the refrigerant, whether residual water left over from the construction of the system, or water released by the degradation of other materials over time.
Schematic representation of a twin tower desiccant compressed air dryer. Desiccant dryers, sometimes referred to as absorption dryers, operate by absorbing water vapor into a porous media with a high affinity for water. [12] [13] These types of dryers are also referred to as absorption systems or getters. Because these dryers get and hold the ...
The blue silica gel in the space below the platform is used as the desiccant. Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity.
Clarke Chapman boilers are made in both 'dry back' (as for the Cochran) and 'wet back' forms. [9] The wet back or "Victoria" [10] (illustrated) has the combustion chamber entirely surrounded by water. This increases the heating surface and reduces lost heat, but it also makes the boiler more complex to manufacture and makes tube cleaning more ...
The first patent for an oxygen scavenger used an alkaline solution of pyrogallic acid in an air-tight vessel. [7] [8]Modern scavenger sachets use a mixture of iron powder and sodium chloride. [8]
Adsorption of water in sodium aluminosilicate which is FDA approved (see below) used as molecular sieve in medical containers to keep contents dry and as food additive having E-number E-554 (anti-caking agent); Preferred for static dehydration in closed liquid or gas systems, e.g., in packaging of drugs, electric components and perishable ...
Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation. The temperature or condition of steam required for ...
