Description
Technical field
The utility model is related to a kind of novel hydrogenation experimental rig, relate in particular to that a kind of laboratory uses small-sized or
Medium-sized hydrogenation test apparatus.
Background technology
Small-sized or medium-sized hydrogenation test apparatus are that technical staff often uses for evaluating catalyst, analoging industrial device
Experimental rig, be engaged in the R＆D institution of hydrogenation using relatively broad.The process CIMS of small test device is simple, treatment
Amount is smaller, is per hour highest 200mL, and hydrogen is recycled, but oil is not circulated, and can typically be only used to catalyst preliminary assessment.In
Type experimental rig process CIMS is complicated, and treating capacity is bigger than normal, is per hour highest 3L, and hydrogen circulation, oil can also be recycled, can
For basic data evaluation is done by refinery.Meanwhile, medium-sized hydrogenation plant wears distillation column system, operates more complicated.Evaluating catalyst
In, qualified light naphthar and bottle coal diesel product can be directly distilled out in fractionating column, so as to accelerate experiment progress.
These small-sized or medium-sized hydrogenation test apparatus generally all include reactor, high-pressure separator, circulating hydrogen compressor,
Low pressure separator and aeration tower.The structure of wherein aeration tower is relatively simple, generally includes high pressure barrel, stainless steel helices and liquid
Level controller.The effect of the stainless steel helices of filling is the area for increasing gas-liquid contact in cylinder.The Main Function of aeration tower is
Wash the H contained in high score gas off2S、NH3、NH4HS or (NH4)2S, to prevent the ammonium salt (NH under high temperature in gas phase4) HS or
(NH4)2S separates out crystallization and blocking pipeline at low temperature in vapor delivery line, and causes the generation of the improper stoppage in transit of device.
Typically, since the structure of aeration tower is different, will cause two kinds of uncertainties occur：One kind is small inflow,
Gas passes rapidly through filler, and water attack is worn, and the fast water of gas is slow；Another kind is that gas is taken a shortcut, and gas and water do not fill in aeration tower
Tap is touched, and is not reaching to wash the H in gas off2The effect of S.In small-sized or medium-sized hydrogenation test apparatus, the injection rate of washings

Gas in contain ammonium salt, device will be caused to occur two kinds of phenomenons in operation：(1) when aeration tower gas returns to mixed hydrogen tank
Mixed hydrogen tank suction line is caused to block and low point of airway blockage；(2) when middle- scale device operating needs out fractionating system, oil is steady
Determine tower and when atmospheric tower is distilled, often result in stabilizer and atmospheric tower top gas circuit NH4Salt crystallization causes the experiment cannot to enter
Row is processed after must fractionating system be stopped transport.Frequently improper stoppage in transit greatly affected entering for normal assays process
OK.

The secondary gas washing of tower, has reached H in abundant washing high score gas2S and NH3Deng purpose, so as to solve device operating in NH4
Salt blocks the problem of gas circuit pipeline.But NH when the utility model has device long-play4Salt is easily in gas-liquid mixed
The problem of device bottom accumulation, and set up air and liquid mixer and can also improve improvement cost and operating pressure, high-temperature gas and washing
Water mixes for a long time, and gas-liquid easily causes pipeline fluctuation, and tolerance and water are whard to control, the deficiency such as gas washing effect difference.
