Chemical Process Principles and Thermodynamics
Ideal gas law PV = nRT with R = 8.314 J/mol·K; use compressibility factor Z for real gases at high pressure or near saturation.
First law for steady open system: Q − W = ΔH + ΔKE + ΔPE; for adiabatic, reversible, negligible kinetic/PE changes, W = −∫V dP.
Entropy change ideal gas: ΔS = Cp ln(T2/T1) − R ln(P2/P1); ΔG = ΔH − TΔS determines spontaneity at constant T and P.
Phase equilibrium requires equality of fugacity of each component in all phases; Raoult's law is the ideal VLE limit, modified by activity coefficients for non-ideality.
Gibbs phase rule F = C − P + 2; for a two-component, two-phase system one intensive variable fixes the state.
Heat of reaction from formation enthalpies: ΔHrxn = Σνi ΔHf,i(products) − Σνi ΔHf,i(reactants); Hess's law applies to any path.
Carnot efficiency η = 1 − Tc/Th (absolute temperatures); real power cycles always fall below this limit.
Material balance on a control volume: accumulation = in − out + generation − consumption; use extent of reaction ξ to close balances on reacting systems.
Unit Operations and Separation Processes
Fick's first law: J = −D dC/dx; mass transfer coefficient correlations (Sherwood = f(Re, Sc)) link diffusion to convective transfer.
Distillation: relative volatility α = (y/x)A/(y/x)B; minimum reflux from pinch point on McCabe-Thiele diagram, minimum stages at total reflux by Fenske equation.
Kremser equation gives theoretical stages for absorption/stripping at constant L/V and constant equilibrium slope.
Heat exchanger design: Q = U A ΔTlm with correction factor F for multipass; ΔTlm = (ΔT1 − ΔT2)/ln(ΔT1/ΔT2).
Filtration: constant-pressure cake filtration follows V² vs t linearity from Darcy's law with specific cake resistance.
Drying: constant-rate period controlled by external heat/mass transfer; falling-rate period controlled by internal diffusion.
Centrifugation separation depends on Stokes settling velocity, proportional to particle diameter squared and density difference, inversely to viscosity.
Membrane processes: flux J = ΔP/(μRm) for pure solvent; concentration polarization reduces observed rejection.
Reaction Engineering and Reactor Design
Batch reactor time: t = ∫ dX/(−rA) from X=0 to X; CSTR volume V = FA0 X/(−rA); PFR volume V = FA0 ∫ dX/(−rA).
Arrhenius: k = A exp(−Ea/RT); plot ln k vs 1/T gives slope −Ea/R.
First-order conversion in CSTR: X = kτ/(1+kτ); in PFR: X = 1 − exp(−kτ), where τ = V/v0.
Selectivity and yield for multiple reactions depend on concentration level; CSTR favors low-concentration pathways, PFR favors high-concentration pathways.
Non-ideal flow diagnosed by residence time distribution; tanks-in-series model fits Peclet number to vessel dispersion.
Catalyst effectiveness factor η = actual rate/rate at surface conditions; Thiele modulus quantifies diffusion limitation.
Energy balance for adiabatic CSTR: T = T0 + (−ΔHr) X/(Σθi Cpi) with θi = feed ratio of species i to reference.
RTD variance for N equal CSTRs in series: σ² = τ²/N; large N approaches plug flow behavior.
Process Safety, Loss Prevention and HAZOP
HAZOP uses guide words (no, more, less, as well as, part of, reverse, other than) applied to node parameters (flow, pressure, temperature, level) to identify deviations.
Layer of protection analysis ranks independent protection layers; each IPL must be independent, specific, dependable, and auditable.
Flash point, autoignition temperature, and lower/upper flammability limits define fire and explosion hazards of flammable vapors.
Dow Fire and Explosion Index and Mond Index quantify inherent process hazard for plant layout and insurance decisions.
Relief sizing for gas: use API 520/521 equations; for liquid thermal expansion use API 521; two-phase relief requires DIERS methodology.
Bow-tie diagram links threats and preventive barriers to top event, then consequence mitigation barriers to outcomes.
LOPA target: required risk reduction = initiating event frequency × consequence severity divided by tolerable frequency.
SIL determination per IEC 61511 uses risk graph or LOPA; SIL 1 to SIL 4 correspond to PFDavg ranges 10⁻¹ to 10⁻⁴.
Nuclear Physics, Reactor Theory and Radiation Protection
Fission of U-235 releases about 200 MeV per event, mostly as kinetic energy of fission fragments and neutrons.
Six-factor formula: k∞ = ε p f η; effective multiplication keff = k∞ P(non-leakage fast) P(non-leakage thermal).
Four-factor formula for thermal reactors: k∞ = ε p f η; reactivity ρ = (keff − 1)/keff, expressed in pcm or dollars.
Delayed neutrons (β ≈ 0.0065 for U-235) enable reactor control; prompt criticality occurs when ρ > β.
