Abstract: An energy consumption analysis of the 3.20 Mt/a hydrotreating unit in Qingdao Refining ＆ Chemical Company was carried out based on the unit performance test data (under full capacity). Some energy saving measures were proposed based on the production status of the plant. Through adopting advanced technology, optimizing operation conditions, implementing technical renovation and enhancing management, the energy consumption of the plant was reduced significantly, in 2010 the energy consumption of the plant reached as low as 198.13 MJ/t, which is the new record of low energy consumption within the same type of units in Sinopec. It also provides energy saving thoughts for new unit design and existing unit revamping.

Key words: hydortreating, energy saving, measure, effect
