Question
Chapter 2, Problem 2.3aA
Interpretation Introduction
Interpretation:
By looking at the activity it should be mentioned if there is any MRF nearby.
It should be explained that if the MRF is present nearby then how does it sorts plastics and if it has any automated sorting equipment.
Concept introduction:
The recycling communities grew significantly under 1990 as they were working like the drop off stations for plastics. Soon it became significant in waste management and it has been noticed that around 2.12 million tons of plastic were recycled by this in 2009. The curbside recycling is helping in reclamation of plastics.

- 14.9. A forward feed double-effect vertical evaporator, with equal heating areas in each effect, is fed with 5 kg/s of a liquor of specific heat capacity of 4.18 kJ/kg K. and with no boiling point rise, so that 50 per cent of the feed liquor is evaporated. The overall heat transfer coefficient in the second effect is 75 per cent of that in the first effect. Steam is fed at 395 K and the boiling point in the second effect is 373 K. The feed is heated by an external heater to the boiling point in the first effect. It is decided to bleed off 0.25 kg/s of vapour from the vapour line to the second effect for use in another process. If the feed is still heated to the boiling point of the first effect by external means, what will be the change in steam consumption of the evaporator unit? For the purpose of calculation, the latent heat of the vapours and of the steam may both be taken as 2230 kJ/kgarrow_forwardExample(3): It is desired to design a double effect evaporator for concentrating a certain caustic soda solution from 12.5wt% to 40wt%.
