Balance and energy

Using the digital simulation approach to steady-state design, the design calculation is shown to proceed naturally from the defining component balance and energy balance equations, giving a considerable simplification to conventional text book approaches. [Pg.253]

We first obtain the appropriate forms of the material-balance and energy-balance equations (12.3-3 1 and 12-3-29, respectively) for use in the above algorithm. [Pg.306]

In this book, both material balances and energy balances are treated on a macroscopic basis, The general macroscopic energy balance for any system is as follows ... [Pg.35]

In a minimum unit HEN the intermediate stream temperatures and heater loads, and thus the breakpoint locations, are uniquely determined by the energy balance and energy recovery constraints. Thus for given supply temperatures and flow rates, the Arm violations (and surpluses) and load violations (and surpluses) in each exchanger k are also uniquely determined. [Pg.39]

For the feasibility test, stream split constraints (Bl) are linear In particular, each g,y is constant since the feasibility test is for specified supply temperatures. Also note that the energy balance and energy recovery constraints are not included in this feasibility test they are used to determine constants aijh cijh and vk, in the stream split, load, and A7 constraints. [Pg.43]

The species (methane and carbon dioxide) mass balance and energy conservation in the cylindrical ring element at steady state lead to the following 2D partial differential equations ... [Pg.36]

Many symptoms of aluminum toxicity are similar to those of Alzheimer s disease and osteoporosis. This suggests that long-term accumulation of aluminum in the brain may contribute to the development of Alzheimer s disease. In addition, an unidentified protein not found in normal brain tissue has been discovered in the brain tissue of Alzheimer s patients. Because aluminum is excreted by the kidneys, toxic amounts of aluminum also may impair kidney function. People who worked in aluminum smelting plants for long periods have been found to experience dizziness, impaired coordination, and losses of balance and energy. Accumulation of aluminum in the brain was cited as a possible cause for these symptoms as well. This has caused concern, especially as it relates to neurotoxicology (Alzheimer s disease).19-21... [Pg.63]

From mass balance and energy balance calculations, the raw material and energy costs are... [Pg.302]

Combination of the material balance Equation 3.30 and the selected equations, which relate the flux vectors for all species to their concentrations, gives a set of equations to be solved subject to the appropriate boundary conditions at the particle surface. If particles cannot be considered as isothermal, the energy balance and energy flux equations are also required. [Pg.53]

Steam turbines with electrical generators are used to recover the power from high pressure steam when the plant steam balance requires additional low pressure steam. As such, they provide more energy-efficient pressure regulation than a simple pressure control valve. Admission or extraction of steam to a header between stages, and/or condensation of exhaust steam fulfill additional steam balance and energy recovery needs. [Pg.56]
