Description
Technical field
The utility model relates to technical field of petrochemical industry, especially a kind of temperature control system of the regenerating continuous reforming catalyst chlorine adsorption tanks that maximize.
Background technology
Modern industry fast development constantly increases the demand of aromatic hydrocarbons, and the increasingly stringent requirement of particularly Environmental protection, catalytic reforming gasoline becomes one of blend component of New standard gasoline middle ideal with its high-octane rating, low alkene and low-sulfur.A large amount of hydrogen of catalytic reforming accessory substance are again for improving oil quality, and the industry of development hydrogenation provides a large amount of cheap hydrogen source.Therefore, catalytic reforming, as the important oil refining process producing high-knock rating gasoline and aromatic hydrocarbons, plays more and more important effect in oil refining, chemical engineering industry.
Catalytic reforming unit presses catalyst regeneration mode, is mainly divided into semi regeneration to reform and CONTINUOUS REFORMER two class.Due to the advantage of CONTINUOUS REFORMER in reaction depth, maximization etc., current new device selects the type substantially.
CONTINUOUS REFORMER improves reaction severity under high temperature, low pressure, obtains high aromatic hydrocarbons or high-octane rating oil.But be thereupon that catalyst knot carbon is fast, cause loss of catalyst activity.Therefore, CONTINUOUS REFORMER adopts the mode of catalyst on-line regeneration to recover catalyst activity.
In order to obtain effective aromatic hydrocarbons or high-octane rating oil, require that reforming catalyst has two large functions: metal center facilitates hydrogenation and dehydrogenation reaction, and the alumina support after chlorination and acid centre facilitate isomerization and cracking reaction.Burn in catalyst regeneration process and the chlorine of catalyst can be made to run off, the loss of chlorine can be reduced by chlorine adsorption tanks, one, to guarantee in outer exhaust that chlorine is little, free from environmental pollution, two, muriatic injection rate can be reduced, reduce production cost.
Along with CONTINUOUS REFORMER maximizes, chlorine adsorption tanks also amplify thereupon, often occur chlorine adsorption tanks thermo-field thoery in process of production, exceed interlocking value, affect equipment safety and run.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiency in above-mentioned background technology, a kind of temperature device of the regenerating continuous reforming catalyst chlorine adsorption tanks that maximize is provided, there is structure simple, run feature easily, improve the security of device, ensure that produce safe and orderly carries out.
The technical solution adopted in the utility model is as follows: a kind of temperature control system of the regenerating continuous reforming catalyst chlorine adsorption tanks that maximize, it is characterized in that: comprise adsorption tanks, nitrogen pipeline and temperature control valve, the temperature detection part of described temperature control valve is connected with the inner chamber of adsorption tanks, the valve part of temperature control valve is arranged on nitrogen pipeline, one end of nitrogen pipeline connects source nitrogen, and the other end accesses described adsorption tanks.
As preferably, described adsorption tanks are connected with process fluid and R1301 pipeline.
The beneficial effect that the utility model has is: it is simple that the utility model has structure, run feature easily, be compared with the prior art, nitrogen addition can be regulated by temperature control valve, utilize the temperature of external cold nitrogen cooling chlorine adsorption tanks, improve the security of device, ensure that produce safe and orderly carries out, thus improve the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, the temperature control system of a kind of regenerating continuous reforming catalyst chlorine adsorption tanks that maximize that the utility model provides, comprise be connected with process fluid 2, the existing adsorption tanks of adsorption tanks 1(of pipeline 4 of dropping a hint, R1301 pipeline 3), also comprise nitrogen pipeline 5 and temperature control valve.The temperature detection part 6-1 of described temperature control valve (outsourcing) is connected with the inner chamber of adsorption tanks by connecting pipe 7 thus is detected the temperature of adsorption tanks inside, the valve part 6-2 of temperature control valve is arranged on nitrogen pipeline, one end of nitrogen pipeline connects source nitrogen (normal temperature or low temperature nitrogenous source), and the other end accesses described adsorption tanks.
Operation principle of the present utility model is: the temperature being detected adsorption tanks by the temperature detection part of temperature control valve, and according to the aperture of temperature control valve door section detected, thus control nitrogen add speed, make the temperature in adsorption tanks remain on zone of reasonableness.
The foregoing is only preferred embodiment of the present utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
