BR&E ProMax 天然气处理工艺流程模拟软件

ProMax是由美国布莱恩研究与工程公司(BR&E)开发,原名TSWEET和PROSIM,是一款强大的工艺流程模拟软件。目前,Promax在世界范围内广泛的应用于天然气加工处理石油炼制等石油化工行业中。ProMax完全按照C++语言面向对象的原则进行设计,这使其能够与Microsoft Visio,Excel和Word等完美的结合在一起,大大扩展了其前身TSWEET 和PROSIM的能力。

Promax在业内以下列几个过程模拟而著称:

(1)天然气处理

ProMax可模拟关于天然气液化(LNG)、天然气的轻烃回收(NGL)、液化石油气的(LPG)的回收和分馏等工艺,并还能进行富氦天然气回收、天然气脱氮及公共工程(蒸汽、冷却水、热油)等一系列工艺的模拟操作。

(2)气体/液体脱硫

在过去的30年里,TSWEET模拟软件的出色表现而在脱硫行业内取得的了很高的声誉,由于BR&E掌握了完整的气液平衡数据,再加上精通多套实际 工程的操作数据,根据这些数据总结及修正了适合脱硫体系的热力学方程,这使得其在脱硫工艺过程中,模拟的数据更加的接近实际工程数据;ProMax可采用 的化学吸收溶剂有MEA、DEA、TEA、DGA®、MDEA、Piperzaine、DIPA、Sulfinol、混合胺及碳酸钾盐等,物理溶剂有 DEPG (Coastal AGR)、NMP(Purisol®)、并还在煤化工行业的低温甲醇洗工艺(Rectisol®)也有突出性能;除了基本的溶剂吸收发外,还可以模拟膜分离法脱碳的工艺。

(3)甘醇法脱水/水合物预测

ProMax在脱水模拟中能够使用EG、DEG、TEG和甲醇。ProMax几乎可以模拟任何关于脱水的单元,包括汽提塔,再生塔等;同样能够准确的预测BTEX和挥发性物质;在ProMax中可以计算干天然气水含量,绘制水合物曲线相图,以及优化甘醇的循环流量。

(4)硫磺回收与尾气净化

硫磺回收已成为全球重点关注的可以减少污染排放的问题之一。ProMax包含了一整套反应动力学模型,如平推流及搅拌,平衡、转换和Gibbs自由能反应模 型。此外,可模拟多种硫磺回收及尾气净化工艺过程,例如 Claus,Selectox®,COPETM,Ultra®,Sulfreen®,SCOT®,SUPERCLAUS®,MODOP®和CBA®。还可 根据酸气中H2S的含量来设定工艺流程的安排,如直流法、分流法、硫循环法、预热酸气法等。

(5)碱法处理酸气

ProMax 提供了改进的热力学方程Caustic-treating-PR/SRK,可以更准确的模拟碱法处理酸气工艺,可以利用NaOH或Na2CO3溶液吸收去 除液态烃或天然气中的酸性气体,如H2S、CO2、硫醇等;如处理只含有硫醇的液体或气体时,碱液还可以在再生塔中进行加热再生或氧化再生。

(6)酸性水处理

ProMax中可以优化蒸汽流率,对不同的汽提方法、回流或不回流系统进行评估;还可对酸液或碱液进行pH值控制;还对酸性水汽提中的氨液精制工艺模拟有很好的准确性。

(7)石油炼制

ProMax可以模拟单一或多种成分的混合油在炼油装置上的应用;根据TBP建立石油的虚拟组分;ProMax可对常、减压蒸馏塔,汽提塔及热泵循环进行建模模拟。

(8)化学过程与反应器

目前ProMax收录了2300多种纯组分,50多种热力学方程,同时还为化学过程提供了一系列强大和灵活的反应器模型,包括平推流反应器,连续搅拌釜,转化率反应器,平衡反应器和Gibbs自由能反应器。
ProMax不仅能进行复杂的化工工艺的模拟建模,还能对反应设备进行设计与校核,如蒸馏塔、吸收塔、硫磺冷凝器、换热器、分离器、管道系统等。

(9)换热器的设计与核算

ProMax 将模拟结果和用户提供的信息相互整合,可以设计计算各种换热器,如管壳式、双管、翅片管、管板式和紧凑式换热器。ProMax可提供与换热器软件HTRI 的接口,可将ProMax的数据完全导入到HTRI中;ProMax还提供了30多种传热液体进行换热设计。

(10)各种塔板的水力学计算

ProMax可以对板式塔、乱堆/规整填料塔、塔内构件等进行设计和核算。在ProMax中,用户可以通过查看塔板的详细数据,从而确定每个产品流中各组分的回收率及优化塔性能。

(11)容器定型

ProMax可以对两相或三相的立式或卧式的分离器进行设计和校核

(12)管道系统

ProMax可对管道系统进行工艺模拟;可对管网系统定义环境温度、管道材质、保温层,计算经济流速、管道压降等。

英文介绍:

ProMax is a powerful and versatile process simulation resource. Its level of flexibility is difficult to describe in one simple document. To enable better understanding of ProMax, particular abilities of ProMax are detailed within what we call a Process Focus..

(一)Amine Sweetening

For over two decades, TSWEET was known as the industry standard for simulating amine sweetening facilities. In an effort to better serve our clients, BR&E has now incorporated TSWEET into ProMax. This union has significantly enhanced the capabilities of our software, especially in the area of amine sweetening. Benefits include more complete thermodynamic models, calculation of more thermo-physical properties and better integration with hydrocarbon packages and unit operations. These benefits allow you to model many more processes such as complex absorber / stripper configurations, three-phase flashes and oils in amine units. The following amines are available either individually or as blends: MEA, DEA, DGA, MDEA, DIPA, TEA, and AMP. ProMax also introduces BR&E’s new Electrolytic-ELR model. This new model is a significant improvement to the NRTL acid gas model in TSWEET. The sweetening package also continues TSWEET’s unprecedented ability to model selective absorption using CO2 kinetics.

(二)Glycol Dehydration

BR&E is the leader in predicting the performance of both glycol dehydration and hydrate suppression systems. Benefits include rigorous predictions for water content, hydrate formation temperature, water dew point and CO2 freeze out. The best in industry BTEX solubility predictions from PROSIM have been carried forward into ProMax.

(三)Crude Oil Refining

Characterize single or multi-component oils and blends for use in common refining applications.

Atmospheric and Vacuum Towers

Complete Oil Characterization and Blending

Three Phase Columns

Side Strippers and Pumparounds

Analyze operational problems

Choose from Assay Types

(四)NGL Fractionation / LPG Recovery

Model separation processes such as cryogenic, refrigeration, J-T, lean oil and other common gas processing applications. You can also model:

NGL and LPG fractionation trains

Refrigeration systems

Plant utility systems, such as steam, cooling water and hot oil

Nitrogen rejection units

Helium recovery units

Others

(五)Caustic Treating

With the improved electrolytic property packages available in ProMax, caustic treating may be modeled to predict the absorption of acid gas compounds and sulfur species such as H2S, CO2, and mercaptans from liquid or vapor streams.

(六)Sulfur Recovery/ Tailgas Cleanup

ProMax  will contain a complete reactor suite that allows simulation of various sulfur recovery and tail gas cleanup plants.

Claus sulfur recovery

Selectox/Recycle Selectox

COPETM

Ultra

Sulfreen

SCOT

SUPERCLAUS

MODOP

CBA

There are a number of Claus sulfur recovery unit configurations available. For example, acid gas bypass, hot gas bypass, enhanced oxygen, catalytic burners and more.

(七)Sour Water Stripper

A much improved sour water stripper model is now available in ProMax. The electrolytic property packages now contain more component interaction data than previously available in TSWEET. Virtually any flow configuration is possible in ProMax.

(八)Pipelines / Gathering System Networks

Specify ambient conditions and overall heat transfer coefficient Calculate pressue drop for horizontal, vertical and inclined flow Obtain results for one, two and three phase flow Select from a wide range of correlations Perform backward calculations.

(九)Reactor Applications

There are numerous refinery and chemical reactor processes which can be modeled with ProMax reactors. The degree of model detail depends on the complexity of the reactions, the availability of any required kinetic or equilibrium information, and the availability of required input information.
