WebThe block flow diagram of a typical hydrotreater is shown in Figure 2 below. The feedstock from the upstream processing unit of a refinery is first heated in the furnace and then sent to the reactor for hydrotreating. The effluents from the reactor are separated in a high and/or low-pressure separator into hydrogen gas and liquid product. Diesel oil may be either a direct cut from the atmospheric distillation column or a mixture of light cycle oil from the fluid catalytic cracker (FCC) unit and heavy cycle oil from the delayed coker. These cuts contain 1–2% sulfur (10,000–20,000 ppm) — much higher than the fuel requirement of 10–15 … Meer weergeven Petroleum refineries transform crude oil into useful fuels and products while satisfying technical, government, and safety requirements.
