Output gas

If the back pressure on the outlet side of the compressor is equal to the fixed Output pressure, then there is no expansion of the output gas in the initial portion of the expansion tank or the initial portion of the pipeline. [Pg.487]

The heat integration of this configuration includes the utilization of the heat generated from the combustion of calcium sulfide in the first chemical loop in the regeneration of the calcium-based sorbent in the second chemical loop (Andrus et al., 2005). The output gas... [Pg.580]

The transmitter and thermocouple have a combined steady-state gain of 0.5 units and negligible time constants. Assuming the solenoid switch to act as a standard on-off element determine the limit of the disturbance in output gas temperature that the system can tolerate. [Pg.346]

Thus the cell is about 127% efficient in terms of power consumption per output gas volume and 175% efficient in terms of current consumption per output gas volume. Surely overunity. [Pg.39]

In a process called direct thermolysis, at a high enough temperature thermal energy is sufficient to split water into hydrogen and oxygen. Only one reaction is involved in this process, that of equation (2.3.1). In Fig. 2.6, if the input water and output gas mixture are at the same temperature To, the minimum work input required to effect water splitting at temperature Tr can be written [60]... [Pg.56]

Cons Throughout this investigation, the risks for data misinterpretation when HT experiments are carried out without satisfactory control of T P conditions were pointed out, possibly combined with physico-chemical side effects like support-induced reaction products adsorption, which may change markedly the output gas concentration and, therefore, the final ranking of performances. [Pg.265]

Perhaps the most efficient and convenient methods for providing a supply of dry oxygen-free inert gas employs BTS catalyst (BASF) in conjunction with molecular sieves. The catalyst is a pelleted form of finely divided copper on an inert support and is used in a system like that shown in Figure 6.7. The nitrogen passes through molecular sieves, BTS catalyst, and another column of molecular sieves. The output gas will have an oxygen and water content each below 1 ppm in a carefully built system. The three-way stopcocks in the inlets are used to bleed the regulators and inlet lines when the cylinders are... [Pg.265]

For injection of gas tracer, a similar system was used with oxygen as tracer. The concentration of oxygen in the output gas was monitored with a paramagnetic analyser. The liquid phase (water) was first saturated with oxygen in the tank (2) before introduction into the column. Preliminary analyses of the feed gas and output gas have shown that absorption or desorption of the tracer was negligible up to a pressure of 1.3 MPa. [Pg.681]

Fig. 21.1. Heat transfer flowsheet for single contact, sulfur burning sulfuric acid plant. It is simpler than industrial plants, which nearly always have 4 catalyst beds rather than 3. The gaseous product is cool, S03 rich gas, ready for H2S04 making. The heat transfer product is superheated steam. All calculations in this chapter are based on this figure s feed gas composition and catalyst bed input gas temperatures. All bed pressures are 1.2 bar. The catalyst bed output gas temperatures are the intercept temperatures calculated in Sections 12.2, 15.2 and 16.3. Fig. 21.1.

Fig. 21.1 s catalyst bed input and output gas enthalpies can be calculated directly on our heatup path-equilibrium curve worksheets, Table 21.1. Table 21.1 s 3rd catalyst bed input gas enthalpy is, for example ... [Pg.236]

Table 21.1. Bottom half of Table O.l s 3rd catalyst bed heatup path-equilibrium curve intercept worksheet. Input and output gas enthalpies are shown in rows 43 and 44. Note that they are the same. This is because our heatup path calculations assume no convective, conductive or radiative heat loss during catalytic SO2+V2O2 —> SO3 oxidation, Section 11.9. 1st and 2nd catalyst bed enthalpies are calculated similarly - using Tables J.2 and M.2. [Pg.238]

These enthalpies are conveniently used to calculate the amount of heat that must be removed to cool a catalyst bed s output gas to a specified temperature. [Pg.241]

Both calculations also estimate the fraction of economizer input gas that must be bypassed around the economizer to achieve a specified output gas temperature. [Pg.243]
