If air is used, then a single pass with respect to each feedstock is used and no recycle to the reactor (Fig. 10.4a).-Thus the process operates at near stoichiometric feed rates to achieve high conversions. Typically, between 0.7 and 1.0 kg of vent gases are emitted per kilogram of dichloroethane produced.  [c.283]

Once the life-cycle inventory has been quantified, we can attempt to characterize and assess the eflfects of the environmental emissions in a life-cycle impact analysis. While the life-cycle inventory can, in principle at least, be readily assessed, the resulting impact is far from straightforward to assess. Environmental impacts are usually not directly comparable. For example, how do we compare the production of a kilogram of heavy metal sludge waste with the production of a ton of contaminated aqueous waste A comparision of two life cycles is required to pick the preferred life cycle.  [c.295]

Adsorption. Adsorption of pollutants by passing the gas through a bed of solid is most suitable when the concentration of pollutant is very low. Materials such as activated carbon, silica gel, or alumina can be used as adsorbent. Activated carbon is the most common adsorbent for organics removal. The adsorptive capacity of the adsorbent (expressed as kilograms of pollutant removed per kilogram of adsorbent) depends not only on the properties of both the adsorbent and the pollutants but also on temperature and pressure. Adsorptive capacity decreases with increasing temperature and increases with increasing pressure.  [c.305]

For fuels it is quite usual to employ kilocalories per kilogram as a measure of calorific value while for foods the unit used is kilocalories per gram. This, however, is often abbreviated to Calories , so that a value for carbohydrates of 4-1 Calories per gram is 4100 calories per gram.  [c.77]

The calorimetric techniques give the weight gross heating value (GHV ) to determine the net heating value (NHV j), the weight hydrogen content of the fuel must be known. If the latter is expressed as a percentage, the mass of water A/produced during combustion of one kilogram of fuel is written  [c.180]

If one imagine.s that the fuel is used in the liquid state in the form of droplets —as in the case of fuel injection— the specific energy of the motor fuel (SE) is expressed in kilojoules per kilogram of air utilized, under predetermined conditions of equivalence ratio (stoichiometry for example). The SE is none other than the NHY /r quotient where r represents the previously defined stoichiometric ratio.  [c.186]

Even A2.4.63 fails at concentrations above about 0.1 M, and the mean activity coefficient for NaCl shown in figure A2.4.6 [2] demonstrates that in more concentrated solutions the activity coefficients begin to rise, often exceeding the value of unity. This rise can be traced to more than one effect. As we shall see below, the inclusion of ion-exclusion effects for all the ions gives rise to this phenomenon. In addition, the ion-ion interactions at higher concentrations caimot really be treated by a hard-sphere model anyway, and models taking into account the true ion-ion potential for solvated ions at close distances are required. Furthennore, the number of solvent molecules essentially iimnobilized in the solvent sheath about each ion becomes a significant fraction of the total amount of solvent present. This can be exemplified by the case of sulphuric acid given that each proton requires four water molecules for solvation and the sulphate ion can be estimated to require one, each mole of H2SO4 will require 9 mol of water. One kilogram of water contains  [c.580]

Writing — j for the kinetic energy of each election amounts to taking our unit of mass as the mass of the election instead of the kilogram (which is an arbitrary unit anyway) and defining h, the unit of angular momentum, as 1. The same thing can be done with the units of charge in an electrical potential, leaving V = l/r or V = .Zjr for multiply charged species. See Me Quarrie (1983) for a table of atomic units and their SI equivalents. The atomic unit of energy in this system is the hartree, h = 4.2359 x 10 joules, and the energy of the ground state of the hydrogen atom is exactly h. Be careful not to confuse the unit h with Planck s constant h.  [c.173]

Plutonium has assumed the position of dominant importance among the trasuranium elements because of its successful use as an explosive ingredient in nuclear weapons and the place which it holds as a key material in the development of industrial use of nuclear power. One kilogram is equivalent to about 22 million kilowatt hours of heat energy. The complete detonation of a kilogram of plutonium produces an explosion equal to about 20,000 tons of chemical explosive.  [c.204]

Using the data in the table scientists, students, and others that are familiar with the periodic table can extract infomiation conceming individual elements. For instance, a scientist can use carbon s atomic mass mass to detemiine how many carbon atoms there are in a 1 kilogram block of carbon.  [c.219]
