Dry methane is supplied by a compressor and precooling system to the cooler of a Linde liquid-methane system (Fig. 9.6) at 180 bar and 300 K. The low-pressure methane leaves the cooler at a temperature 6 K (6°C) lower than the temperature of the incoming high-pressure methane. The separator operates at 1 bar, and the product is saturated liquid at this pressure. What is the maximum fraction of the methane entering the cooler that can be liquefied?
Discuss the consequent effects on the real and reactive power losses, and on the voltage drop across the series impedance of the transmission system.
Consider a 1-bit version of the digital comparator shown in Figure P6.1.41. Note that the operation of this circuit is such that whichever output is 1 gives the desired magnitude comparison.
Compute the eddy-current loss in this core when the frequency is 750 Hz and the maximum flux density is 0.8 T.
Develop expressions for the mole fractions of the reacting species as functions of the reaction coordinates for the two reactions.
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
