2S separates out crystallization and blocking pipeline at low temperatures in the gas phase pipeline, and causes the generation of the improper stoppage in transit of device.
In testing apparatus running, the gas that height branches away enters in the scrubber tower from scrubber tower top with after the washing water of injection (or alkaline detergent solution) mix, by the promoting the circulation of qi liquid separation of going forward side by side of the stainless steel filler in the scrubber tower.Because the unreasonable structure of scrubber tower, will cause occurring two kinds of uncertainties: a kind of is that flooding quantity is little, and gas passes filler fast, and water attack is worn, and the fast water of gas is slow; Another kind is that gas is taken a shortcut, and not fully contact in scrubber tower of G﹠W does not reach the H that washes off in the gas
2The effect of S.
In small-sized or medium-sized hydropyrolysis experiment device, the injection rate of washing water is bigger usually, generally accounts for more than the 25wt%～50wt% of oil inlet quantity.Yet on-stream discovery, because the structure of scrubber tower is unreasonable, washing water and high score gas contacting in scrubber tower is insufficient, washing water are to H in the high score gas
