Abstract

A feasibility study and investigation of a pilot plant for power generation and seawater distillation utilizing the energy generated by the combustion of oil shale in a fluidized bed is carried out. About 10.09 kg/s of oil shale is combusted by about 23.93 kg's of air at a temperature of around 500 °C in the fluidized bed of 5 m in diameter to generate power of about 12.55 MW. About 3.45 MW of that power is used to run the feed air compressor to the combustion bed at a velocity of around 28.4 m/s. Although about 0.18 MW is estimated to be consumed by the power plant water pump, a total of 0.6 MW is assumed to accommodate the running power required by all the pumps for circulating the water in the power plant and the multistage flash evaporator. This leaves about 8.5 MW (about one percent of current total Jordanian electricity demand) to generate electricity
A ten-stage flash evaporator makes use of the energy in the power plant condenser to heat up the brine water to produce about 30.3 kg/s (about 109 m/h) of distillate water when 350 kg/s of seawater part of which 60% re-circulated brine water is forced through the stages of the flash evaporator
