据世界天然气网站5月14日消息 霍尼韦尔称，全球风投液化天然气公司将使用霍尼韦尔环球油品公司（霍尼韦尔UOP）的一系列技术，在路易斯安那州卡梅伦地区的Calcasieu Pass液化天然气出口设施液化前清除天然气中的各种污染物。
霍尼韦尔UOP在声明中称，该公司将为该综合设施提供工程设计、采购和制造服务。该综合设施建成后每年将生产1000万吨液化天然气，用于出口至亚洲、欧洲和其他地区的市场。
霍尼韦尔UOP天然气处理和氢气业务副总裁兼总经理本·欧文斯在谈到该项目时表示：“与传统的现场施工系统相比，通过以模块化的形式交付该技术，我们可以降低施工和安装成本。”
该项目将包括一个霍尼韦尔UOP除汞装置（MRU）和三条独立的生产线，每个生产线由一个酸气脱除装置（AGRU）和分子筛脱水装置组成。
这些模块化装置将每天从16亿标准立方英尺的天然气中去除水、汞、二氧化碳和硫，从而可以使其液化并安全地通过远洋船只运输给客户。
汞在大多数天然气中以低浓度自然存在。为了保护液化天然气的低温设备，必须采用有效的除汞工艺。
其他自然产生的污染物，如硫化氢和二氧化碳，通常被称为酸性气体，在液化之前必须从天然气中清除。天然气通过AGRU中的胺溶液进行处理。在处理后，利用UOP分子筛脱水天然气，以除去所有的水，以防止低温液化过程中的冻结。

Honeywell UOP tech chosen for Calcasieu Pass LNG
Honeywell said that Venture Global LNG will use a series of technologies from Honeywell UOP to remove various contaminants from natural gas prior to liquefaction at its Calcasieu Pass LNG export facility in Cameron Parish, Louisiana.
Honeywell UOP will provide engineering, procurement and fabrication services for the complex which, when completed, will produce 10 million tons per annum (mtpa) of liquefied natural gas (LNG) for export to markets in Asia, Europe and other locations, the company said in its statement.
Speaking of the project Ben Owens, vice president and general manager of Honeywell UOP’s gas processing and hydrogen business said, “by delivering this technology in modular form, we can reduce construction and installation costs compared with traditional field-constructed systems.”
The project will include a Honeywell UOP Mercury Removal Unit (MRU) and three separate trains each consisting of an Acid Gas Removal Unit (AGRU) and molecular sieve dehydration unit.
Taken together, these modular units will remove water, mercury, carbon dioxide and sulfur from 1.6 billion standard cubic feet per day of natural gas so it can be liquefied and safely transported to customers Mercury occurs naturally in small concentrations in most natural gas. Effective mercury removal processes are necessary to protect cryogenic equipment used to liquefy natural gas.
Other naturally occurring contaminants such as hydrogen sulfide and carbon dioxide, often referred to as acid gases, must be removed from natural gas before it can be liquefied. The natural gas is treated by passing it through an amine solution in the AGRU. After being treated, the natural gas is dehydrated using UOP molecular sieves to remove all the water to prevent freezing in the cryogenic liquefaction process.
