Material and Energy Balances Review ChE 160 SI – Becca Fall 2016

Exam Notes Calculator 50/50 calculations and programming Cumulative (including matlab functions)

Broad Topics ChemE professional problem format Material balances Energy balances Engineering economics Write down: Everything you remember about these topics on the front Topics you’re questionable about or don’t quite remember on the back Write for at least 1 minute

Specific Topics Problem presentation General closed energy balance General material balance equation E bal assumptions Internal E (U) vs enthalpy (H) Mat. balance assumptions I, P, F, A, n, i Continuous vs batch APR Degrees of Freedom EUAC Process flow diagram Cash flow diagrams Recycle and Bypass General open energy balance

What is the standard chemical engineering problem presentation format? Diagram Given Find Assume Solution Analysis

General material balance equation In – Out + Generation – Consumption = Accumulation In – Out = 0

Degrees of Freedom # Unknowns # Components or material balances # Physical constraints (x1 + x2 = 1) # Process specifications

General Energy Balance Equations Closed Q - Ws = ΔKE + ΔPE + ΔU Open Q - Ws = ΔKE + ΔPE + ΔH

Energy Balance Term Cancellation Q = 0 System and surroundings have same T or if the system is perfectly insulated (adiabatic) W = 0 No moving parts, electrical currents, radiation ΔKE = 0 System is not accelerating ΔPE = 0 System does not rise or fall (no change in height) ΔU = 0 No ΔT, no phase change, no reaction

Engineering Economics I, P, F, A, n, i APR EUAC = Equivalent Uniform Annual Cost Net present value Cash Flow Diagrams

How did that go?
