(PDF) RECOVERY OF PETROLEUM COKE FROM LIME

Nowadays, due to its low price and high calorific value Petroleum coke (petcoke) is a quite fair alternative energy source for such plants. Unburned carbon is the main byproduct of lime calcination process which has significant calorific value and can be reused in system. This byproduct is thrown out by heat flux from flue of vertical furnace.

Removal of sulfur from petroleum coke with lime - Berg, Lloyd

1990-4-13  Petroleum pitch has a has a viscosity of about 350 Centistokes at 350° F., the temperature at which it should be heated in order to pump it into the furnace. We found that with coarse fluid petroleum coke, about 40% coke, 60% pitch was a mixture that could still be pumped. With dry sawdust, 25% sawdust, 75% pitch was pumpable.

2000-11-20  The petroleum coke may have a very high content of sulphur, up to 6-7 per cent. Petroleum coke alone, or mixed with residual oil, will be used as fuel. As stringent demands are put on the SO2 emissions, it was necessary to combine sulphur removal by limestone addition to the CFB with a tail end desulphurisation system, hence the use of NID.

Petroleum Coke - an overview ScienceDirect Topics

Petroleum coke can be fired in combination with coals or heavy oils in circulating fluidized bed boilers; alternatively, it can be fired as the sole fuel. Some examples of petroleum coke firing in fluidized bed boilers are shown in Table 5.16. Other examples of CFB boilers firing petroleum coke alone or in combination with other fuels include installations at the Nova Scotia Power Pt.
