Abstract
PURPOSE: To perform with good operation stability hydrogenation of an olefin produced by the thermal cracking of heavy oil and to reduce energy cost required, by controlling operation temp. by the circulation of part of used gas.
CONSTITUTION: Circulation gas 4 is added to gas mixt. 3 consisting of raw material gas 1 obtd. by the thermal cracking of heavy oil and hydrogen 2, and the resulting gas 5 is passed through hydrogenating column 10 and desulfurizing column 12 after heated at furnace 6, to perpare refined gas 13. Part 14 of the refined gas is sent to the next step, and the rest is supplied to heat exchanger 16 as circulation gas 15 and sent to compressor 21 after cooled at cooler 18. Pressurized gas 22 obtd. is mixed with said circulation gas 4 after heated at said heat exchanger 16 and then added to the gas mixt 3. An amt. of the gas returned is controlled by mean of valve 24 placed in by-pass line 23.
