Petro Chemistry

To understand the field of petrochemistry it’s important to comprehend what petroleum is and where it comes from. Over millions of years, natural changes in organic materials have produced petroleum which has accumulated under the earth’s surface. Petroleum rich areas are generally found in regions that support retention, such as porous sandstones. Crude oils are naturally occurring liquids made up of various hydrocarbon compounds that differ in appearance and composition. Average composition rates are 84% carbon, 14% hydrogen, 1%-3% sulphur, and less than 1% each of nitrogen, oxygen, metals and salts. Depending on the sulphur content crude oils are either categorised as sweet or sour.
