Summary
In the evaporation the concentration of the feed (product) is usually increased by boiling out (evaporating out) solvent which is usually water (GEA 2012). The concentrate (evaporator end product)…

From the cooler the acetic acid stream containing paracetamol and water (product) enters evaporator for concentration (increasing its concentration) by removal of certain portions of water from the product. Consider the flow diagram below;
According to mass balance principle, mass of materials entering a system is equal to the mass of materials leaving the system assuming that there are neither losses within the system nor losses associated with the processes under which the materials entering the system undergo (Wacharawichanant 2012). This can be expressed mathematically as shown below,
As of the case of processing paracetamol, the rate of mass of products (paracetamol) entering the evaporator is equal to rate of mass of mass of concentrate leaving the system plus rate of mass of vapour leaving the system. Mass balance can be expressed mathematically as shown below, (consider Figure 1)
The mass of the products from cooler, (the mass of Acetic acid + Water + paracetamol) was 2319 Kg per hour (Kg/hr) (From L-37) of the Engineering line diagram (report 2). After evaporation the mass of the concentrate obtained per hour was 1380.85 Kg per hour. Therefore, the mass of the vapour (acetic acid vapur) assuming that no loss occurred as a result of evaporation process can be calculated as follows.
In order that required quantity of paracetamol per year is obtained, and assuming other factors are constant, the product from the cooler should be fed at rate of 2319 Kilograms per hour or 55656 Kilograms per day (assuming that the plant will work 24 hours per day).
A measure of concentration process that takes place in the evaporator is what is known as evaporation ratio, and it is calculated as shown above. When concentrating the solution F (dilute paracetamol) at a steady rate, the concentration rate starts ...Download file to see next pagesRead More

...? Determinants of Substance Abuse School: Determinants of Substance Abuse Substance abuse has remained a major concern among groups of all ages. Throughout an ordinary day in 2006, the following numbers of youths took the following substances: 7,970 took alcohol, 4,348 took illicit drugs, 4082 smoked cigarettes and 2517 took pain relievers without a doctor’s prescription (Johnston et al., 2010). The smoking of marijuana increased across learners, including those of 8th, 10th and 12th grade, during the time between year 2009 and 2010. Among 12th grade students, the smoking of marijuana was at its peak, because 6.1 percent of school seniors consumed marijuana (UDHHS, 2010). In 2009, people between 18 and 25 had the highest levels... Determinants...

...Discuss the Processes that must Occur at the End of a PRESYNAPTIC AXON to Cause the Release of a Neurotransmitter and then the Effects the Neurotransmitter has on the POSTSYNAPTIC NEURON to Cause that Neuron to form Action Potentials. The transmission of information at chemical synapses involves the release of a neurotransmitter from a presynaptic cell, diffusion across the synaptic cleft, and binding of the neurotransmitter to specific receptors on the postsynaptic membrane to produce a change in membrane potential. In chemical synapses, there is a gap between the presynaptic cell membrane and the postsynaptic cell membrane, known as the synaptic cleft. Information is transmitted across the synaptic...
