***guyz...may napulot lang ako sa wikipedia....hmm...nakakatuwa at may history ang ating course....taralets read it.....heheh!!***

Chemical engineering as a discipline is a little over a hundred years old. Historically, it grew out of mechanical engineering towards the last part of the 19th century, in response to the specialized needs of chemical processing. Before the advent of the industrial revolution (18th century), the demand for industrial chemicals was largely met by batch processing, which is something like cooking – one added the needed ingredients at the beginning of the process into a vessel, arranged a sequence of conditions such as temperature, pressure etc., tested the quality of the product after sufficient time, and if deemed good enough, stopped the process, opened the vessel and took out the contents, finally subjecting them to further purification steps in order to get a saleable product answering to a set of specifications. In such processing, small batch-to-batch variations in quality could not be eliminated, but the process could be operated with even a limited level of understanding of how chemistry operated on a large scale.

The industrial revolution led to an unprecedented escalation in demand, both with regard to quantity and quality, for bulk chemicals such as sulfuric acid and soda ash. This meant two things: one, the size of the activity and the efficiency of operation had to be enlarged, and two, serious alternatives to batch processing, such as continuous operation, had to be examined. This created the need for an engineer who was not only conversant with how machines behaved, but also understood chemical reactions and transport phenomena (how substances came together to react, how the required conditions could be acheived, etc), and the influence the equipment had on how these processes operated on the large scale. Thus, chemical engineering was born as a distinct discipline; distinct from both mechanical engineering on one hand and industrial chemistry on the other.

The set of 12 lectures that George Davis presented at the Manchester Technical School in 1887 can be regarded as the forerunner of chemical engineering syllabi as a separate discipline. This organisation of course material came to be the hallmark of chemical engineering. Shortly thereafter, the Chemistry department of the Massachusetts Institute of Technology started the first four-year program in chemical engineering called Course X (ten). Other programs soon followed.

These early programs married industrial chemistry with mechanical engineering, with the emphasis most decidedly on engineering. But chemical engineers still needed to clearly define their activity as something more than a mishmash of chemistry and engineering. To emphasize their identity and thus help the growth of their profession, chemical engineers formed the American Institute of Chemical Engineers in 1908. For the other established branches of engineeering, there were ready associations in the mind of the common man: mechanical engineering meant machines, electrical engineering meant circuitry, and civil engineering meant structures. So what symbolized chemical engineering? The answer, provided by Arthur D. Little to the President of AIChE, was to emphasize the approach chemical engineers took to the design and analysis of processes rather than a process or a product. The concept of Unit operations was developed to emphasise the underlying unity among seemingly different operations. For example, the principles are the same whether one is concerned about separating alcohol from water in a fermenter, or separating gasoline from diesel in a refinery, as long as the basis of separation is generation of a vapor of a different composition from the liquid. Therefore such separation processes can be studied together as a unit operation (in this case called distillation). The concept has stood the profession in good stead in its phase of growth, and has even been used to understand the way the human body functions.

In the early part of the last century, a parallel concept called Unit Processes was used to classify reactive processes. Thus oxidations, reductions, alkylations etc. formed separate unit processes and were studied as such. This was natural considering the close affinity of chemical engineering to industrial chemistry at its inception. Gradually however, the subject of chemical reaction engineering has largely replaced the unit process concept. This subject looks at the entire body of chemical reactions as having a personality of its own, independent of the particular chemical species or chemical bonds involved. The latter does contribute to this personality in no small measure, but to design and operate chemical reactors, a knowledge of characteristics such as rate behaviour, thermodynamics, single or multiphase nature, etc. are more important. The emergence of chemical reaction engineering as a discipline truly signaled the severance of the umbilical cord connecting chemical engineering to industrial chemistry, and served to cement the truly unique character of this discipline.

*ang kool nitong story...sorry kung mushy pero inspiring naman toh eh...heheh!*

The cheerful girl with bouncy golden curls was almost five.Waiting with her mother at the checkout stand, shesaw them: a circle of glistening white pearls in a pink foil box. "Oh please, Mommy. Can I have them?Please, Mommy, please?"Quickly the mother checked the back of the little foil box and then looked back into the pleading blue eyes of her little girl's upturned face."A dollar ninety-five. That's almost $2.00. If you really want them, I'll think of some extra chores for you and in no time you can save enough money to buy them for yourself. Your birthday's only a week away and you might get another crisp dollar bill from Grandma."

As soon as Jenny got home, she emptied her penny bank and counted out 17 pennies. After dinner, she did more than her share of chores and she went to the neighbor and asked Mrs. McJames if she could pick dandelions for ten cents.On her birthday, Grandma did give her another new dollar bill and at last she had enough money to buy the necklace. Jenny loved her pearls. They made her feel dressed up and grown up. She wore them everywhere - Sunday school, kindergarten, even to bed.The only time she took them off was when she went swimming or had a bubble bath. Mother said if they got wet, they might turn her neck green.

Jenny had a very loving daddy and every night when she was ready for bed, he would stop whatever he was doing and come upstairs to read her a story.One night when he finished the story, he asked Jenny, "Do you love me?""Oh yes, Daddy. You know that I love you." "Then give me your pearls.""Oh, Daddy, not my pearls. But you can have Princess - the white horse from my collection. The one with the pink tail.Remember, Daddy? The one you gave me. She's my favorite.""That's okay, Honey. Daddy loves you. Goodnight." And he brushed her cheek with a kiss.About a week later, after the story time, Jenny's daddy asked again, "Do you love me?""Daddy, you know I love you.""Then give me your pearls.""Oh Daddy, not my pearls. But you can have my baby doll. The brand new one I got for my birthday. She is so beautiful and you can have the yellow blanket that matches her sleeper.""That's okay. Sleep well. God bless you, littleone. Daddy loves you"And as always, he brushed her cheek with a gentle kiss.

A few nights later when her daddy came in, Jenny was sitting on her bed with her legs crossed Indian-style. As he came close, he noticed her chin was trembling and one silent tear rolled down her cheek."What is it, Jenny? What's the matter?" Jenny didn't say anything but lifted her little hand upto her daddy.And when she opened it, there was her little pearl necklace. With a little quiver, she finally said,"Here, Daddy. It's for you."With tears gathering in his own eyes, Jenny's kind daddy reached out with one hand to take the dime-store necklace, and with the other hand he reached into his pocket and pulled out a blue velvet case with a strand of genuine pearls and gave them to Jenny. He had them all the time. He was just waiting for her to give up the dime-store stuff so he could give her genuine treasure.

So it is with our Heavenly Father. He is waiting for us to give up the cheap things in our lives so that he can give us beautiful treasure.Isn't God good? Are you holding onto things which God wants you to let go of?Are you holding on to harmful or unnecessary partners, relationships, habits and activities which you have come so attached to that it seems impossible to let go of?Sometimes it is so hard to see what is in the other hand, but do believe this onething..............

God will never take away something without giving you something better to take its place.

kung sinabi mo noon ako'y iyong mahal
di sana ay tayo na ang nagkatuluyan
at sinabi ko noon ikaw ang mahal ko
ito'y tapat at may dalang walang hanggang pangako
ngunit di nagkatotoo
may iba kang nakita
kaya't nakapagtataka
ba't ako'y hinahanap mo pa
kung tayo'y magkikita muli
pwede bang magtanong sayo
ang tibok ba ng puso mo'y nagbago
kung sinabi mo noon ikay may pagtingin
di sana ay wala ng makakapaghadlang sa atin
nung sinabi ko noon na ikaw lang ang mahal
ang nasa isip ko ito'y magtatagal
ngunit di nagkatotoo
may iba kang nakita
kayat nakapagtataka
bat ako'y hinahanap mo pa
kung tayo'y magkikita muli
pwede bang magtanong sayo
ang tibok ba ng puso mo'y nagbago
