Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
Most venturi systems operate with an L/G ratio of 0.4 to 1.3 L/m 3 (3 to 10 gal/1000 ft 3). [4] L/G ratios less than 0.4 L/m 3 (3 gal/1000 ft 3) are usually not sufficient to cover the throat, and adding more than 1.3 L/m 3 (10 gal/1000 ft 3) does not usually significantly improve particle collection efficiency.
This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte [2] with negatively charged carboxylic groups in the main chain. It is a polymer made up of chains of acrylate compounds.
Canisters are commonly filled with silica gel and other molecular sieves as desiccants in drug containers to keep contents dry Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5]
Aspen Plus, Aspen HYSYS, ChemCad and MATLAB, PRO are the commonly used process simulators for modeling, simulation and optimization of a distillation process in the chemical industries. [1] [2] Distillation is the technique of preferential separation of the more volatile components from the less volatile ones in a feed followed by condensation ...
The first type of lithium bromide absorption heat pump unit is a high-temperature heat source (steam, high-temperature hot water, fuel oil, gas) as the driving heat source, lithium bromide solution as the absorbent, and water as the refrigerant, and the low-temperature heat source (such as waste hot water) is recycled and used.

In high energy physics experiments, an absorber is a block of material used to absorb some of the energy of an incident particle in an experiment. Absorbers can be made of a variety of materials, depending on the purpose; lead , tungsten and liquid hydrogen are common choices. [ 1 ]
