Auxiliary energies

Process chemicals (such as non-acid treatment, add treatment) and auxiliary electridty required for pumps vary for the six processes. Generally processes that require more auxiliary electricity require less chemical treatment. The evaporation processes generally require sulfamic or hydrochloric acid for dean-ing requirements depend upon the location. Reverse osmosis may require chlorine and cleaning agents such as detergents. [Pg.209]

For WTW analysis, it is a sufficiently accurate assumption, that natural gas mainly consists of methane (CFI4). Compressed natural gas is also referred to as CNG . Natural gas is extracted, processed, transported and distributed via pipeline to the filling stations, where it is compressed to about 25 MPa. Natural gas sources may vary for different countries. Depending on the source (natural gas quality) and the transport distance (e.g., 4000 km or even 7000 km from Russia, depending on the relevant gas fields) the auxiliary energy needs or energy losses, and hence the GHG-relevant emissions can vary. For the calculation of the energy requirement and GHG emissions for the supply of natural gas, a transport distance of 4000 km is assumed. [Pg.209]

Flow systems are developed mainly for liquid samples and their complexity can range from simple to very complex manifolds to deal with ultratrace amounts of the target analyte in complex matrices, which often require on-line separation/preconcentration steps. As a wide variety of chemical manipulations can be carried out in an FI manifold, the scope of the FI applications is enormous. Not only liquid samples, but also both gas and solid samples, can be also introduced into the liquid flow manifold if special adaptations are made. Gas samples simply require impermeable tubing. Solids can be either introduced into the system and leached with the help of auxiliary energy e.g. ultrasound) or introduced as slurries. [Pg.33]

Finally, the development of automated methods for wet decomposition of solid samples without human participation can only be achieved with the use of a robotic station [183]. Nevertheless, a number of auxiliary energies and commercially available modules can facilitate and/or accelerate this time-consuming step of the analytical process (i.e., obtain the analyte(s) from a solid sample in the form of a solution). [Pg.114]

Digestion. The influence of ultrasound on the dissolution kinetics of phosphate rock in HNO3 solutions [11] and variables affecting it (viz. particle size, reaction temperature, acid concentration, amplitude of US power) were studied by Tekin [12]. The term dissolution in the presence of auxiliary energy and an acid seems inappropriate in this case as the process is more like a true digestion. Another case in point is the dissolution of pyrite ores in acid and Fe2(S04)3 solutions, which is improved by 30% with respect to the absence of US energy [13]. [Pg.42]

Although liposomes can form spontaneously, they are rarely thermodynamically stable, so they usually require some auxiliary energy such as mechanical agitation, electric energy, US or combination of mechanical treatments. The main advantage of US assistance here is that it does not raise the temperature significantly. Ultrasonic energy has been used to assist the two most common methods of liposome preparation, namely ... [Pg.221]

Although analytical chemists have shown little interest in the use of ultrasound, its potential usually surpasses that of other, conventional auxiliary energies. Thus, ultrasound is of great help in the pretreatment of solid samples as it facilitates and accelerates operations such as the extraction of organic and inorganic compounds [2,3], slurry dispersion [4], homogenization [5] and various others [6-8]. [Pg.43]

As stated above, the use of ultrasound as auxiliary energy for leaching has been widely exploited for the extraction of a variety of analytes from different types of solid samples. While ultrasonic irradiation has been advantageously used over other methods to accelerate manual leaching of solid samples, this type of energy has scarcely been employed for pretreatment in continuous systems, even though it expedites the sampling process considerably. [Pg.54]

The answer is c. (Murray, pp 199-207. Scriver, pp 1521-1552. Sack, pp 121-138. Wilson, pp 287-317.) Muscle phosphorylase deficiency leads to a glycogen storage disease [McArdles disease (232600)] and, in young adults, an inability to do strenuous physical work because of muscular cramps resulting from ischemia. The compromised phosphorylation of muscle glycogen characteristic of McArdle s disease compels the muscles to rely on auxiliary energy sources such as free fatty acids and ambient glu-... [Pg.171]
