Description

煤直接液化模拟方法及装置 Direct coal liquefaction of a method and apparatus

技术领域 FIELD

[0001] 本发明涉及煤化工领域,具体而言,涉及一种煤直接液化模拟方法及装置。 [0001] The present invention relates to coal chemical industry, particularly, to a simulation method and a direct coal liquefaction apparatus.

背景技术 Background technique

[0002] 在煤化工领域中,煤直接液化技术是在高温高压条件下,利用供氢溶剂和催化剂, 使氢元素进入煤及其衍生物的分子结构中,从而将固体煤转化为液化燃料的先进的洁净煤技术。 [0002] In the field of coal chemical industry, the direct coal liquefaction technology under high temperature and pressure conditions, the use of hydrogen-donating solvent and a catalyst, and hydrogen elements into the molecular structure of coal derivatives, whereby solid coal into the liquefied fuel advanced clean coal technology. 通过煤直接液化技术,不仅可以生产汽油、柴油、液化石油气和喷气燃料油,还可以提取轻质芳烃(苯、甲苯和二甲苯混合物,简称为BTX),以及生产乙烯、丙烯等重要烯烃。 By direct coal liquefaction technology, not only can produce gasoline, diesel, jet fuel and LPG, light may be extracted aromatic hydrocarbons (benzene, toluene and xylene mixtures, referred to as the BTX), and the production of ethylene, propylene and other important olefins.

[0003] 煤直接液化的过程是一个复杂的物理过程和化学过程的结合,其中包含小分子从煤大分子网络结构中的脱离、煤中大分子键的断裂、活性基碎片的稳定、溶剂的供氢、聚合反应等。 [0003] The direct coal liquefaction process is a combination of a complex physical and chemical processes, wherein the coal comprises a small molecule from the macromolecular network structure from coal macromolecules bond cleavage, fragments stable reactive groups, the solvent for hydrogen, the polymerization reaction or the like. 一直以来,对煤直接液化反应过程的模拟方法是,在获得大量试验数据的基础上, 推导合适的反应动力学模型及其模型参数,再通过编程拟合获取煤直接液化反应过程的模拟结果。 Conventionally, simulation of direct coal liquefaction reaction process is to obtain a large amount of test data on the basis of the derived appropriate kinetic model and the model parameters, and then fitting the acquired simulation program directly through the coal liquefaction reaction process. 但是,由于在反应模型推导过程中,采用的动力学模型较少,因此模拟出的结果也仅包含气体、油品、沥青烯等产物;把反应过程模拟当作黑箱来处理,只能获取最终的反应结果,而无法获知反应过程进行中各产物浓度、反应器内部温度等信息;一般很少考虑反应器结构、气含率等操作条件对模拟结果的影响,即使考虑也仅仅采用编程者手动计算并写入程序的方式实现,缺乏便捷性;模拟结果具有单一性,一般只是输出产品收率。 However, since the reaction in the model derivation, less dynamic model used, and therefore only the results of simulated also contain gas, oil, asphaltenes and other products; the reaction process simulation treated as a black box, only to obtain the final the results of the reaction, the reaction process can not know each product concentration, temperature and other information inside the reactor; rarely consider the impact of operating conditions of the reactor structure, the gas holdup on the simulation results, even considering only be programmed manually using calculated and implemented writer manner, the lack of convenience; simulation results is unitary, generally only output product yield.

[0004] 随着流程模拟技术的发展,在流程模拟软件中,借鉴强大的物性及热力学数据库, 采用用户自定义模块,通过用户后台编程的方式也可实现模拟煤直接液化工艺的反应单元。 [0004] With the development of technology, process simulation, process simulation in software, draw a strong and thermodynamic properties database, using the user-defined modules, user background may also be implemented programmatically simulate the reaction section of a direct coal liquefaction process. 但是,同样地,这种处理方式也是把反应单元作为黑箱进行处理,无法获得反应过程中反应器内部温度、浓度等信息。 However, in the same manner, this approach is the reaction unit are processed as a black box can not be obtained during the reaction the internal temperature of the reactor, the concentration of other information. 并且,随着煤种、反应动力学模型改变,需重新调整计算模型,并编写反应子程序接口,因此使用起来相当不便。 Also, as coal, reaction kinetic model change, the need to re-adjust the model calculation, and write subroutine interfaces the reaction, and therefore rather inconvenient to use. 同时,因为上述所有工作均基于流程模拟软件进行,因此需购进成熟的商业化流程模拟软件,而这种软件价格非常昂贵,因此大幅提升了该方法的使用成本,这在一定程度上也阻碍了该方法的应用和推广。 At the same time, because all of the above are based on process simulation software, and therefore need to purchase mature commercial process simulation software, and the software is very expensive, and therefore greatly enhance the use of the cost method, which is also hampered to some extent, the application and promotion of the method.
