Description
Technical field
The utility model relates to the evaluation of light hydrocarbon gas phase, is specifically related to a kind of light hydrocarbon gas phase evaluating apparatus.
Background technology
In commercial plant, industrial gasses are common sulfur removal technologies with the desulfurization of gas phase mode.But in laboratory evaluation device, under some normal temperature and pressures, be gas and slightly pressurization or cooling are just easy to the raw material of liquefaction, as propylene, butane or liquefied petroleum gas (LPG), conventionally in liquid mode, be stored in steel cylinder, for these raw materials, with the desulfurization of gas phase mode, often exist desulfurized effect apparently higher than the problem of desulfurizing agent virtual rating, show desulphurizing ability excessively strong, the problem that time of break-through is long, evaluation result can not real embodiment desulfurizing agent in the application level of commercial plant.
Research discovery, an one main cause is, before desulfurization, these liquid are after gasification is for gas, and the composition of gas comprises sulfur-bearing situation, does not obviously conform to the sulfur-bearing situation of liquid in whole steel cylinder, such as sulfur content in gas is low, the sulfocompound that of gasifying is more easily desulfurized agent and removes.
Such as, in common evaluating apparatus, steel cylinder mouth connects reduction valve, liquid gasifies in steel cylinder, after reduction valve, gas connects mass flowmeter, enter to be equipped with again the reaction tube of desulfurizing agent, the shortcoming of this common mode is, the sulfur content of gas is usually less than the sulfur content of liquid in steel cylinder, reason is that liquid when gasify in steel cylinder, the boiling point of most sulfocompounds is far above the boiling point of liquid, gasification is still-process, in gasification, most of sulfocompound has been stayed in liquid, gasification is not out, the sulfocompound that of gasifying is also more easily desulfurized agent and removes, so measured desulfurizing agent desulphurizing ability is strong and time of break-through is long.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the true desulphurizing ability and the time of break-through that provide a kind of evaluation result can accurately embody and reflect desulfurizing agent, real embodiment desulfurizing agent is at the light hydrocarbon gas phase evaluating apparatus of commercial plant application level.
The utility model solves the technical scheme that its technical matters adopts:
Described light hydrocarbon gas phase evaluating apparatus, comprise steel cylinder, in steel cylinder, being equipped with under normal temperature and pressure is gas and slightly pressurization or cooling are just easy to the raw material of liquefaction, steel cylinder is connected successively with liquid feed pipe with pressure, gasifier, decompressor, flow controller, the reaction tube that desulfurizing agent is housed, H2S detector, and gasifier, decompressor are co-located in thermostat.
Described flow controller preferred mass flowmeter.
Research finds, gasifier, decompressor are co-located in thermostat, make liquid in gasifier continuously, stably gasification.In gasification, enter each component in the liquid in gasifier, comprise sulfocompound, all all gasifications, so, as long as the sulfur-bearing situation of the liquid flowing out continuously from steel cylinder is identical with the sulfur-bearing situation of liquid in whole steel cylinder, so, the gas after gasification just can reflect the sulfur-bearing situation of liquid in whole steel cylinder.Thereby, the reaction tube institute air inlet body sulfur-bearing situation that desulfurizing agent is housed is identical with the sulfur-bearing situation of liquid in whole steel cylinder, so evaluation result can accurately embody and reflect true desulphurizing ability and the time of break-through of desulfurizing agent, can real embodiment desulfurizing agent in commercial plant application level.
Further research is found, gasifier internal volume be equipped with desulfurizing agent the desired gas per minute of reaction tube charge flow rate standard state volume 0.5-5 doubly, preferably 1-2 times time, liquid gasifies more stable in gasifier, cost is lower, effect is better.
The beneficial effect that the utility model has is:
The utility model is co-located on gasifier, decompressor in thermostat, make liquid in gasifier continuously, stably gasification, guaranteed the accurate of evaluation result, can accurately embody and reflect true desulphurizing ability and the time of break-through of desulfurizing agent, the application level of real embodiment desulfurizing agent on commercial plant.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, liquid feed pipe with pressure; 2, thermostat; 3, flow controller; 4, the reaction tube of desulfurizing agent is housed; 5, H2S detector; 6, decompressor; 7, gasifier; 8, steel cylinder.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, described light hydrocarbon gas phase evaluating apparatus, comprise steel cylinder 8, in steel cylinder 8, being equipped with under normal temperature and pressure is gas and slightly pressurization or cooling are just easy to the raw material of liquefaction, steel cylinder 8 is connected successively with liquid feed pipe 1 with pressure, gasifier 7, decompressor 6, flow controller 3, the reaction tube 4 that desulfurizing agent is housed, H2S detector 5, and gasifier 7, decompressor 6 are co-located in thermostat 2.
Described flow controller 3 is mass flowmeter.
The utility model is co-located on gasifier 7, decompressor 6 in thermostat 2, make liquid interior continuously at gasifier 7, stably gasification.In gasification, enter each component in the liquid in gasifier 7, comprise sulfocompound, all all gasifications, so, as long as the sulfur-bearing situation of the liquid flowing out continuously from steel cylinder 8 is identical with the sulfur-bearing situation of liquid in whole steel cylinder 8, so, the gas after gasification just can reflect the sulfur-bearing situation of liquid in whole steel cylinder 8.Thereby, 4 air inlet body sulfur-bearing situations of reaction tube that desulfurizing agent is housed are identical with the sulfur-bearing situation of liquid in whole steel cylinder 8, so evaluation result can accurately embody and reflect true desulphurizing ability and the time of break-through of desulfurizing agent, can real embodiment desulfurizing agent in commercial plant application level.
When gasifier 7 internal volumes be equipped with desulfurizing agent the desired gas per minute of reaction tube 4 charge flow rate standard state volume 0.5-5 doubly, preferably 1-2 times time, liquid is more stable in the interior gasification of gasifier 7, cost is lower, effect is better.
