Schematic diagram of thermal power plant. Fluid catalytic cracking fcc is one of the most important conversion processes used in petroleum refineriesit is widely used to convert the high boiling high molecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline olefinic gases and other products. The solar updraft tower sut is a design concept for a renewable energy power plant for generating electricity from low temperature solar heat. The resulting convection causes a hot air updraft in the tower by the chimney effect. Sunshine heats the air beneath a very wide greenhouse like roofed collector structure surrounding the central base of a very tall chimney tower.
Cracking of petroleum hydrocarbons was originally done by thermal cracking which has been almost.
