Q1 (20 points) What is the difference between steady state and unsteady state process? (20 points) Q2 (60 points) Draw the Block Diagram (BD) for the following chemical process: 1. The raw materials (toluene and hydrogen) are added to a reactor 2. The product is transferred to a gas separator", and the "mixed gas" and "mixed liquids" are separated 3. The "mixed liquid" goes to a "distillation column" and the product (benzene) is separated 4. The remaining "toluene" is sent back to the "reactor" for further processing. Requirements and rubric: Correct drawing and streams connections (30 points) Components and stream labeling (15 points) Correct labelling of each block (15 points) 03 (20 points) Explain the following chemical process. Specify the raw materials (6 points), products (4 points) and unit operations (10 points). Raw Biogas Fresh Solvent Recycled Solvent Absorber Concentrated Gas Treated Gas Spent Solvent Stripper Steam
