Design approaches

Having converted the VOC-recovery problem into a heat-transfer task we now proceed to develop the design procedure. [Pg.251]

The design procedure starts by identifying the minimum utility cost for a given heat-transfer driving force. Next, the fixed and operating costs are traded off by iterating over the driving forces until the minimum total annualized cost TAC is attained. [Pg.251]

It is beneficial to develop the enthalpy expressions for the gaseous VOC-laden stream as its temperature is cooled from T to some arbitrary temperature, T, which is below T . Assuming that the latent heat of the VOC remains constant over the condensation range, the enthalpy change (e.g., kJ/kmole of VOC-ftee gaseous stream) can be approximated through [Pg.251]

CHAPTER TEN Sjnrilhesis of tieal lnduced separation network [Pg.252]

For each value of P, Eq. (I0.3b) is used to determine y which in turn is employed in Eq. (10.7) to calculate T. As can be seen from Fig. 10.3, for a given T the value of Q is determined graphically. In addition, the outlet temp re for the gaseous stream leaving the network, T , is identified. [Pg.252]

CHAPTER TEN Synthesis of heat lnduced separation network [Pg.252]

The next step is to screen the candidate refrigeiants with the bbjecdve of mini-miztng the udlity cost. This step can be accomplished by examining the cost of [Pg.252]


How closely a design approaches minimum energy is largely determined by the raw materials and catalyst system chosen. However, if reaction temperature, residence time, and diluent are the only variables, there is still a tremendous opportunity to influence energy use via the effect on yield. Even given none of these, there is stiU wide freedom to optimize the heat interchange system (see Reactor technology). [Pg.83]

Eig. 2. Microstmctural design approaches for composite interfaces (a) mechanically weak coating (b) porous interface and (c) ductile interface. [Pg.48]

A recent addition to the model-based tuning correlations is Internal Model Control (Rivera, Morari, and Skogestad, Internal Model Control 4 PID Controller Design, lEC Proc. Des. Dev., 25, 252, 1986), which offers some advantages over the other methods described here. However, the correlations are similar to the ones discussed above. Other plant testing and controller design approaches such as frequency response can be used for more complicated models. [Pg.729]

The design approach is particularly feasible for those reactions in which chemical and pore diffusion rates are most important. For flow related phenomena semi-empirical, dimensionless correlations must be relied on. Therefore in this book scale-up will be used in the more general sense with the airri of using methods that are fundamentally based wherever feasible. [Pg.1]

The development of the probabilistic design approach, as already touched on, includes elements of probability theory and statistics. The introductory statistical methods discussed in Appendix I provide a useful background for some of the more advanced topics covered next. Wherever possible, the application of the statistical methods is done so through the use of realistic examples, and in some cases with the aid of computer software. [Pg.135]

What are the best guess maximum and minimum limits of the load current and are there any intermittent characteristics in its current demand such as those presented by motors, video monitors, pulsed loads, and so forth Always add 50 percent more to what is told to you since these estimates always turn out to be low. Also what are the maximum excursions in supply voltage that the designer feels that the circuit can withstand. This dictates the design approaches of the cross-regulation of the outputs, and feedback compensation in order to provide the needs of the loads. [Pg.2]

A Generalized Design Approach to Power Supplies Introducing the Building-block Approach to Power Supply Design... [Pg.8]

The only function of the voltage feedback loop is to hold the output voltage(s) at a constant value. Complications arise in areas such as transient load response, accuracy of the output(s), multiple outputs, and isolated outputs. All of these individually can be nightmares for the designer, but if the design approaches are understood then each factor can easily be satisfactorily addressed. [Pg.75]

The purpose of this book is not to advance the bastions of academia, but to offer the tried and true design approaches implemented by many engineers in the power held. It offers advice and examples which can be immediately applied to the reader s own designs. [Pg.276]

When an installation is being planned, it is recommended that the API Standard 618 be reviewed in detail. The pulsation level for API 618 at Design Approach 1, the outlet side of any pulsation control device regardless of type, should be no larger than 2% peak-to-peak of the line pressure, or the value given by the following equation, whichever is less... [Pg.84]

For those installations where a detailed pulsation analysis, API 618 Design Approach 2 or 3, is required,. several consulting companies offer these services. Until the 1980s, the most common method was to perform the pulsation analysis on the analog simulator of the Pipeline and Compres.sor Research Council of the Southern Gas Association. The... [Pg.85]

The theory relating stress, strain, time and temperature of viscoelastic materials is complex. For many practical purposes it is often better to use an ad hoc system known as the pseudo-elastic design approach. This approach uses classical elastic analysis but employs time- and temperature-dependent data obtained from creep curves and their derivatives. In outline the procedure consists of the following steps ... [Pg.200]
