2. Comparison of Processes
먼저 기존의 추출 방법에 대해 알아보자.
2.1. Steam distillation
Steam distillation이란 끓는점이 높고, 물에 거의 녹지 않는 유기화합물에 수증기를 불어넣어, 그 물질의 끓는점보다 낮은 온도에서 수증기와 함께 유출되어 나오는 물질의 증기를 냉각하여, 물과의 혼합물로서 응축시키고
Oil Sand 분리공정의 효율성을 높일 수 있다고 판단된다.
2. 4 아스펜 Simulation
위에서 언급한 오일샌드로부터 bitumen을 추출하는 2가지 방법은 물리적인 힘을 가하는 방법이므로 아스펜으로 simulation하기 힘들었다. 따라서 upgrading공정에 대하여 아스펜으로 simulation을 해보았다. 공정도 자체를 그리는 것은
위 그림은 Oil Sands에 Bacteria를 넣어줌으로써 Bacteria가 oil과 water의 interface에서 oil을 degradation 할 수 있도록 해주는 것이다. Bacteria는 oil과 같은 hydrocarbon을 degrade시켜서 methane gas를 배출한다. Oil Sands가 전부 degradation되어 methane gas로 변하고 나면 우리는 단순히 이 천연가스를 뽑아내기만 하면 될 것이다. 이
FPSO란?
종래의 해양 시추 작업은 고정된 플랜트에서 Oil의 시추 및 정제를 거친 뒤 육상 저장 설비에 보내어 저장하는 방식이었다.
이러한 방식은 플랜트가 시추 및 Well fluid의 정제를 모두 담당하기 때문에 생산 설비를 설치함으로써 플랜트의 덩치가 커지게 되고, 육상 설비에 긴 파이프라인을 연결

For this reason, since the start of the operation for the first nuclear power plant in Gori in 1978,
The nuclear power plants currently supply about 40% of the electricity penetration rate of total domestic. As electricity penetration rate by nuclear power plant is increasing, amount of radioactive waste generated in the operation process of nuclear power plants is rapidly incre

What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments

Tubular type
Advantage: do not need air sealing & formed on strong support ->mechanical property is great & resistance from heat is great
Disadvantage: power density is small
Economical characteristic
Do not use expansive catalyst
Do not need reforming
Do not need electrolyte supplement
Price is cheaper than others
Technical characteristic
simple process cause
