Dictionary
Condensate
mixture of light hydrocarbons in a liquid state.
Conversion
interrelation of light products (gases, petrol and gas oils) and residue, in relation to entry raw material, expressed in percentages. Conversion depends on the type of raw material, pressure, temperature and spatial velocity. Conversion also means transforming one product into another.
Cracking
chemical reaction of cracking big organic molecules and making small molecules under the effect of higher temperature. By cracking molecules of kerogen, bitumen and petroleum are produced, and by cracking oil, condensate and gas are produced.
Chemical compound
matters consisting of identical molecules made of atoms of several elements; matter consisting of more elements.
Cogeneration
simultaneous production of electrical power using gas and steam turbines.
Collector
perforated (porous) and<strong> </strong>permeable rock (deposit, layer) where fluids and gases can accumulate; when vaulted by impermeable rocks, can be a reservoir of petroleum and natural gas.
Compressor station
(CS), facility for compressing natural gas to a higher pressure, consists of necessary number of compressors with engines running on gas or electricity.
Condensation
transformation of vapours into liquid state by cooling.
Catalysts
chemical compounds that expedite chemical reactions but do not participate in these reactions.
Tar
the term ‘natural tar’ is sometimes used for heavy petroleum (bitumen) that has penetrated to the surface of the Earth; heavy residues discharged from gases during gasification of coal and wood, feedstock for chemical industry; deposits in chimneys where furnaces are fed with coal or wood.
Wheel grease
grease for oiling axles of horse-drawn and other vehicles; in the past, a product of simple refining of heavy petroleum from natural sources.
