BASTILLE Dey,,,,,,,,,,,,,,

TANGGAL 14 Juli adalah hari kemerdekaan Prancis yang lebih dikenal dengan "Bastille Day", sebagai simbol berakhirnya era kerajaan dan dimulainya pemerintahan republik.

Kalo orang-orang di perancis nyebutnya Fête Nationale ("National Celebration") ato juga disebut quatorze juillet ("14 July")

Nah,,semalam,,alias malam senen tadi,,kita2 yang di BSP juga ngadain party bastille day. Lho,kok bisa,,,,ya jelas lah,wong yang ngadaain perusahaan,kita mah tinggal nikmatin ajah,lumayan bisa cuci-cuci mata liatain mbak2 penyanyi n dancer2nya. Tapiiiiii,,mbak2 penyanyi n dancernya semalam gak se-hot mbak2 yang taon taon kemaren,,gak tahu nih yang milih band ama dancernya sapa..

Emmm.....dari tadi tulisana ajah,,,,yah,biar asik kita kasih gambar2nya liputan semalam okeh......


nah ini potonya mas aji(yang pake batik) n mas muso(yang sebelahnya lah...)....dua bapak ini seniorku ditempat kerjaan,,,,.....2 bapak ini bela2in gak nonton motoGP n mantengin nih acara bastille day dari awal...(kayaknya sih,,abis, aku dateng ke acaranya ditengah2 acara...)



OKeh,,,nih kita kasih poto2nya lagi...

ini poto mbak penarinya,,,gak tahu nih dia nari apaan,,,,gerak2 terus mbakanya,,,,susah betul mau di poto..........


lanjottt lage...................

hiya....ininih....bapak2(tua betul kayaknya,dipanggil pak....) lagi show off,,nyanyi2 didepan,,dengan mengusung nama band mereka GASoil Band,,,,,tuh ada mas aji yang ikut2an joget,,,,,wak,,wak,,,wak,,,,,,,

karena waktu yang blum memungkinkan untuk menyelesaikan liputan bastille daynya sekarang,,,,,,,,liputan beserta potonya dilanjutin di next post aja yah,,,dah jam % sore nih,,,mo mandi dulu,,sholat ashar(keasikan ngeblog mpe lupa solat,,,)maem,,,trus kita kerja malem,,,,,

ALarm bodoh......................

What the hack hah...........

"eeeeemmmmmmmmmmmmm..............."
"............................................."
"eeeeemmmmmmmmmmmmm..............."
"............................................"
"eeeeemmmmmmmmmmmmm..............."

(ceritanya diatas itu suara alarmnya fire/gas leak, mirip gak ya...)

ah shit,,,apa pula ini.tumben jumat alarmnya jam 11.
Biasanya juga jam 1/2 12..ada yang gak beres nih..
"ada kebakaran di PPa,harap segera kumpul ke muster point...",,,suara kontrol dari radio....
ah,,ada2 saja,,paling juga exercise,,tapi masa hari jumat,,jam 11 lagi exercisenya...

"taik emang orang2 ini,,anda komunis kah pak,,,kelaut ajah dah....." batinkuhhh

dengan bersemangat kukelilingi dulu process,,sapa tahu masih ada orang2 kerja yang didalam...

baru mau menancap sepeda naik tanjakan,,rasanya udah malas,mana panas lagi.kayaknya juga dah gak ada orang lagi process.dari pada kepanasan mending langsung turun aja ke posko ikutan baris di muster point.


panas.....panas...............panas...........(kejadian ini berlangsung lumayan...1/2 jam berjemur dibawah terik matahari......).


setelah setengah jam berjemur, dan berkacamata hitam kayak bule2 yang lagi dipantai,,,akhirnya terdengar suara alarm bodoh lagi....

"eeeeeeeemmmmmmmmmmmmmm......................"
"keadaan emergency telah teratasi,keadaan telah aman,para pekerja sudah bisa kembali ketempat masing-masing...."ini katanya orang kontrol,,,tapi lewat toa,,gak lewat radio ngomongnya....
abis itu ada suara..."ting....tung.............."

alarmnya sekali ajah,,,,gak banyak2,,,soalnya udah abis suaranya buat alarm bodoh yang pertama tadi......


"ahh...selesai juga akhirnya........."
"saatnya makan..............."

untuk berita...eh cerita selanjutnya kita lanjutkan nanti yah,,,,okeh.!

OIL REFINING

Okeh,,,mari kita berdongeng ria tentang oil refiining,ni cerita tentang minyak,,dari mana asalnya,apa aja komponennya,gimana ngolahnya..mau jadi apa ntar,bisa dibaca di postingan ini.
Sebenarnya tak bikin postingan ini mah kalo sewaktu2 dirikuw mau baca2 tentang oil=lengo.jadi gak bingung lagi cari filenya di falshdisk.
Tapi ini bukan hasil penelitian saya. bahannya tak ambil dari postingan nya bank jay,

Yang mau baca2 sebelum tidur silahkan.......
Siapa tahu bisa ngantuk dan tertidur dengan pulas setelah baca dongeng minyak ini......hehehe....
okeh,,,,,


Crude Oil
On average, crude oils are made of the following elements or compounds:
• Carbon - 84%
• Hydrogen - 14%

• Sulfur - 1 to 3% (hydrogen sulfide, sulfides, disulfides, elemental sulfur)
• Nitrogen - less than 1% (basic compounds with amine groups)
• Oxygen - less than 1% (found in organic compounds such as carbon dioxide, phenols,
ketones, carboxylic acids)
• Metals - less than 1% (nickel, iron, vanadium, copper, arsenic)
• Salts - less than 1% (sodium chloride, magnesium chloride, calcium chloride)

Crude oil is the term for "unprocessed" oil, the stuff that comes out of the ground. It is also known as petroleum. Crude oil is a fossil fuel, meaning that it was made naturally from decaying plants and animals living in ancient seas millions of years ago -- anywhere you find crude oil was once a sea bed. Crude oils vary in color, from clear to tar-black, and in viscosity, from water to almost solid.

Crude oils are such a useful starting point for so many different substances because they contain hydrocarbons. Hydrocarbons are molecules that contain hydrogen and carbon and come in various lengths and structures, from straight chains to branching chains to rings.

There are two things that make hydrocarbons exciting to chemists:

• Hydrocarbons contain a lot of energy. Many of the things derived from crude oil like gasoline, diesel fuel, paraffin wax and so on take advantage of this energy.
• Hydrocarbons can take on many different forms. The smallest hydrocarbon is methane (CH4), which is a gas that is a lighter than air. Longer chains with 5 or more carbons are liquids. Very long chains are solids like wax or tar. By chemically cross-linking hydrocarbon chains you can get everything from synthetic rubber to nylon to the plastic in tupperware. Hydrocarbon chains are very versatile!

The major classes of hydrocarbons in crude oils include:

• Paraffins
 general formula: CnH2n+2 (n is a whole number, usually from 1 to 20)
 straight- or branched-chain molecules
 can be gasses or liquids at room temperature depending upon the molecule
 examples: methane, ethane, propane, butane, isobutane, pentane, hexane

• Aromatics
 general formula: C6H5 - Y (Y is a longer, straight molecule that connects to the
benzene ring)
 ringed structures with one or more rings
 rings contain six carbon atoms, with alternating double and single bonds between the
carbons
 typically liquids
 examples: benzene, napthalene

• Napthenes or Cycloalkanes
 general formula: CnH2n (n is a whole number usually from 1 to 20)
 ringed structures with one or more rings
 rings contain only single bonds between the carbon atoms
 typically liquids at room temperature
 examples: cyclohexane, methyl cyclopentane

• Other hydrocarbons

 Alkenes
• general formula: CnH2n (n is a whole number, usually from 1 to 20)
• linear or branched chain molecules containing one carbon-carbon double-bond
• can be liquid or gas
• examples: ethylene, butene, isobutene

 Dienes and Alkynes
• general formula: CnH2n-2 (n is a whole number, usually from 1 to 20)
• linear or branched chain molecules containing two carbon-carbon double-bonds
• can be liquid or gas
• examples: acetylene, butadienes

From Crude Oil
The problem with crude oil is that it contains hundreds of different types of hydrocarbons all mixed together. You have to separate the different types of hydrocarbons to have anything useful. Fortunately there is an easy way to separate things, and this is what oil refining is all about.
Different hydrocarbon chain lengths all have progressively higher boiling points, so they can all be separated by distillation. This is what happens in an oil refinery - in one part of the process, crude oil is heated and the different chains are pulled out by their vaporization temperatures. Each different chain length has a different property that makes it useful in a different way. To understand the diversity contained in crude oil, and to understand why refining crude oil is so important in our society, look through the following list of products that come from crude oil:

• Petroleum gas - used for heating, cooking, making plastics
 small alkanes (1 to 4 carbon atoms)
 commonly known by the names methane, ethane, propane, butane
 boiling range = less than 104 degrees Fahrenheit / 40 degrees Celsius
 often liquified under pressure to create LPG (liquified petroleum gas)

• Naphtha or Ligroin - intermediate that will be further processed to make gasoline
 mix of 5 to 9 carbon atom alkanes
 boiling range = 140 to 212 degrees Fahrenheit / 60 to 100 degrees Celsius

• Gasoline - motor fuel
 liquid
 mix of alkanes and cycloalkanes (5 to 12 carbon atoms)
 boiling range = 104 to 401 degrees Fahrenheit / 40 to 205 degrees Celsius

• Kerosene - fuel for jet engines and tractors; starting material for making other products
 liquid
 mix of alkanes (10 to 18 carbons) and aromatics
 boiling range = 350 to 617 degrees Fahrenheit / 175 to 325 degrees Celsius

• Gas oil or Diesel distillate - used for diesel fuel and heating oil; starting material for making
other products
 liquid
 alkanes containing 12 or more carbon atoms
 boiling range = 482 to 662 degrees Fahrenheit / 250 to 350 degrees Celsius

• Lubricating oil - used for motor oil, grease, other lubricants
 liquid
 long chain (20 to 50 carbon atoms) alkanes, cycloalkanes, aromatics
 boiling range = 572 to 700 degrees Fahrenheit / 300 to 370 degrees Celsius

• Heavy gas or Fuel oil - used for industrial fuel; starting material for making other products
 liquid
 long chain (20 to 70 carbon atoms) alkanes, cycloalkanes, aromatics
 boiling range = 700 to 1112 degrees Fahrenheit / 370 to 600 degrees Celsius

• Residuals - coke, asphalt, tar, waxes; starting material for making other products
 solid
 multiple-ringed compounds with 70 or more carbon atoms
 boiling range = greater than 1112 degrees Fahrenheit / 600 degrees Celsius

You may have noticed that all of these products have different sizes and boiling ranges. Chemists take advantage of these properties when refining oil. Look at the next section to find out the details of this fascinating process.

The Refining Process
As mentioned previously, a barrel of crude oil has a mixture of all sorts of hydrocarbons in it. Oil refining separates everything into useful substances. Chemists use the following steps:

1. The oldest and most common way to separate things into various components (called fractions), is to do it using the differences in boiling temperature. This process is called fractional distillation. You basically heat crude oil up, let it vaporize and then condense the vapor.

2. Newer techniques use Chemical processing on some of the fractions to make others, in a process called conversion. Chemical processing, for example, can break longer chains into shorter ones. This allows a refinery to turn diesel fuel into gasoline depending on the demand for gasoline.

3. Refineries must treat the fractions to remove impurities.

4. Refineries combine the various fractions (processed, unprocessed) into mixtures to make desired products. For example, different mixtures of chains can create gasolines with different octane ratings.

The products are stored on-site until they can be delivered to various markets such as gas stations, airports and chemical plants. In addition to making the oil-based products, refineries must also treat the wastes involved in the processes to minimize air and water pollution.

Fractional Distillation
The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. The steps of fractional distillation are as follows:

1. You heat the mixture of two or more substances (liquids) with different boiling points to a high temperature. Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius.

2. The mixture boils, forming vapor (gases); most substances go into the vapor phase.

3. The vapor enters the bottom of a long column (fractional distillation column) that is filled with trays or plates.
• The trays have many holes or bubble caps (like a loosened cap on a soda bottle) in them to allow the vapor to pass through.
• The trays increase the contact time between the vapor and the liquids in the column.
• The trays help to collect liquids that form at various heights in the column.
• There is a temperature difference across the column (hot at the bottom, cool at the top).

4. The vapor rises in the column.

5. As the vapor rises through the trays in the column, it cools.

6. When a substance in the vapor reaches a height where the temperature of the column is equal to that substance's boiling point, it will condense to form a liquid. (The substance with the lowest boiling point will condense at the highest point in the column; substances with higher boiling points will condense lower in the column.).

7. The trays collect the various liquid fractions.

8. The collected liquid fractions may:
• pass to condensers, which cool them further, and then go to storage tanks
• go to other areas for further chemical processing

Fractional distillation is useful for separating a mixture of substances with narrow differences in boiling points, and is the most important step in the refining process.

Very few of the components come out of the fractional distillation column ready for market. Many of them must be chemically processed to make other fractions. For example, only 40% of distilled crude oil is gasoline; however, gasoline is one of the major products made by oil companies. Rather than continually distilling large quantities of crude oil, oil companies chemically process some other fractions from the distillation column to make gasoline; this processing increases the yield of gasoline from each barrel of crude oil.

Chemical Processing
You can change one fraction into another by one of three methods:
• breaking large hydrocarbons into smaller pieces (cracking)
• combining smaller pieces to make larger ones (unification)
• rearranging various pieces to make desired hydrocarbons (alteration)
