Chart Industries pioneered the use of BAHX for cryogenic gas processing in the 1950s and we’ve produced over 13,000 units since. A Chart BAHX is a highly efficient, all brazed and welded compact heat exchange device that offers distinct advantages versus other heat exchanger types. They are designed in accordance with the world’s pressure vessel codes and deployed globally. Our principal design and manufacturing facility is in La Crosse, Wisconsin. Notable Chart firsts include the introduction of vacuum brazing, Core-in-Kettle® and mercury tolerant construction. Additionally, we are continually innovating and investing in our technology and capacity to remain the market leader enabling our customers to maximize their opportunities.

Plate fin heat exchangers are essential for cryogenic gas processing applications including Air Separation, LNG liquefaction, Nitrogen Rejection, Natural Gas Liquids (NGL) Recovery, Propane Dehydrogenation, Hydrogen Recovery and other low temperature natural gas and petrochemical processes. In addition to stand-alone units Chart offers fully assembled and tested battery assemblies and Cold Boxes.

Cold Box

Cold box Phases

Single plate fin heat exchangers can be supplied pedestal mounted and insulated locally in the field. However, when the service requires multiple units assembled in series and/or parallel and ancillary process equipment such as vessels and drums, a cold box is the most efficient solution.

从外部上讲,冷箱是一种由碳钢制造而成的壳体,并配有法兰连接,方便在现场连接至生产工艺管道。It's best described as a process module incorporating all the following:

  • Supports and houses
    • heat exchangers
    • piping
    • other related cryogenic equipment
    • insulation material
  • Provides inert atmosphere
  • Modular assembly, includes instrumentation
  • Multiple services in a single piece of hardware
  • Complete, compact package

Chart 的主要冷箱制造地位于美国路易斯安那州新伊比利亚市,这座滨海而建的工厂占地 40 英亩,并可直通美国两岸水道和墨西哥湾。

冷箱制造由美国美国威斯康星州拉克罗斯市和德克萨斯州伍德兰德市的设计和工程团队提供支持。

Core-in-Kettle®

Chart’s patented Core-in-Kettle®, introduced in 1989, further extends the use of Brazed Aluminum Heat Exchanger technology in a range of petrochemical and natural gas processes as an alternative to traditional shell and tube kettle reboilers. 外部容器采用了一个或多个铝钎焊热交换器取代管束,并提供比等效釜式和壳管式装置多 10 倍的传热面积和多 20 倍的“UA”。

The superior heat transfer performance can be utilized to produce a significantly more compact unit for new installations, or considerably more performance can be provided to existing installations by replacing the tube bundle with a BAHX retro-fitted into the same shell. 这是解决加工厂瓶颈问题的特效解决方案。

铝钎焊热交换器结构可实现低至 2°F (1°C) 的低温差,从而显著降低功耗并减少压缩机功率。

Core-in-Kettle® 采用什么工作原理?

  1. The warm process stream fluid enters the heat exchanger through steel inlet nozzle(s) on the vessel shell. 入口喷嘴通过铝至不锈钢过渡耦合连接至交换器的铝制入口管。
  2. 在 BAHX 中,热流逆着冷流流动时逐渐冷却下来。
  3. 冷流作为液体或两相流体直接从蒸馏塔(或膨胀阀,若使用制冷剂)进入容器。
  4. BAHX 芯体外部形成液面以产生液压头,从而驱动冷流流过芯体。
  5. 芯体上方的分离空间使液体和蒸气分离。
  6. 被冷却的热流则离开 BAHX 和容器。
  7. 冷流蒸气过出口喷嘴排出容器,而液体则回流再循环。
  8. 容器外壳设有检修孔。

Continuous Innovation

We continually innovate to enable our customers to meet their challenges and to further optimize the performance and longevity of our equipment. Before you purchase your next BAHX, ask us about the following design and construction features:

Mercury Tolerant Construction - under certain conditions liquid elemental mercury can have a detrimental effect on unprotected BAHX. Chart’s proprietary solution combines multiple design, material selection and fabrication features that work in tandem with guard beds to protect against attack. Since pioneering the technology in the 1980s Chart has supplied >800 mercury tolerant units with no reported field failures.

Smart Layer - patent pending, is a predictive maintenance solution intended to provide prior warning that a plate fin exchanger is getting towards the end of its normal service life. Once triggered, Smart Layer™ enables the unit to function normally while the requisite corrective action is planned, thereby avoiding the significant cost and upset of an emergency shutdown.

Support Services

Increased awareness, attention to operating data and process control will improve plant safety and reliability. Through Chart Lifecycle, we offer pro-active services intended to maintain the health and performance of your heat exchanger fleet to mitigate the risk of plant downtime and financial impact of lost production and revenue.
