Natural gas filter separators are used in various industries to remove impurities from natural gas. Natural gas is an important resource for many industries and it is important to keep it free of impurities. Filter separators help with this by removing particulate matter, water, and other impurities from the gas.
The function of a filter separator is to protect downstream equipment from solid particles and liquids that can damage or clog equipment. Separators are usually installed upstream of the equipment to be protected.
In this article, we will discuss the important role of natural gas filter separators. We’ll also briefly describe what it is and how it works.
Natural gas, also known as fuel gas, is a mixture of hydrocarbon gases, the main component of which is methane. It is a type of fossil fuel that can be used alone in underground reservoirs or mixed with crude oil in oil fields. It is very common in the manufacturing process of glass, plastic, steel, and more.
Natural gas can also be used as a fuel for heating applications, and many homes now use natural gas heating systems. Power generation is the largest consumer of natural gas. When natural gas is used to generate energy, its advantages are more obvious than other fuels. It burns cleaner and does not pollute the environment.
There are many liquid and solid pollutants in the initial state of natural gas. Only by removing these pollutants one by one, can natural gas reach the standard for industrial use.
Filter separators are used to filter liquids and solids from natural gas and are a universal solution. There are two types of filter separators, one is high pressure (≥500PSI), and the other is low pressure (<500PSI), the type of selection depends on process conditions and applications.
Generally, it will have several stages, depending on the filtering requirements. The first stage passes airflow into the filter cartridge, trapping solid particles and condensing any liquid from the gas into larger droplets. In the second stage, the moisture-laden gas enters the filter separator, and the heavier liquid is hit and dropped from the gas stream with the help of velocity loss and gravity, removing the coalesced liquid.
The efficient operation of natural gas power plants requires fuel gas, which requires the purification of raw natural gas and conversion into usable gas. This involves the removal of solid and liquid contaminants. Below are some of the products and processes involved in natural gas filtration:
The use of a single-cylinder or double-cylinder basket strainer is the first step in the pipeline purification of natural gas and is mainly used to remove more significant solid pollutants. Strainers can be made from various materials, although carbon steel is preferred. The strainer basket is mostly stainless steel, durable and reusable. Basket strainers can effectively remove solid contaminants (as small as 100 microns), and even smaller contaminants if specially designed are used.
Separators are mainly used to separate large liquid contaminants such as hydrocarbon oils, gels, and water from natural gas streams in pipelines. In the separator, the natural gas stream is forced through a series of devices such as inertial separators, vanes, and more. Because of these devices, the smaller droplets become large droplets, which settle and separate at the bottom of the vessel.
Coalescing filters is the final step in cleaning natural gas. Even though the basket filter removes the larger solid particles and the separator collects most of the liquid particles, there are still fine contaminants in the natural gas. At this time, a filter coalescer is required to remove the remaining solid and liquid contaminants as small as 1 micron or even smaller, and the effect can be as high as 99.9%.
Brother Filtration researches and manufactures a wide range of liquid, oil, and gas filtration products. Coalescer and separator filter series can meet the needs of removing particles in liquid and liquid gas, and separating particles in liquid and gas. It has a wide range of applications, not only for natural gas filtration but also for chemicals, fragrances, and different types of oils.
SP1.0 separator filter cartridge
SP1.0 elements are high-efficiency filter separator elements with molded fiberglass tubes made from graded fiberglass. The filter element removes particles as small as 1 micron without excessive differential pressure.
SP2.0 separator filter cartridge
SP 2.0 separator elements are effective in treating process water from a huge range of liquids, and can also be utilized for industrial use without requiring API authentication. Separator elements greatly improve production efficiency and minimize the equipment’s operating costs.
CLL1.0 coalescer filter cartridge(liquid from liquid)
CLL 1.0 coalescing filter elements are widely used in liquid/liquid separations in the chemical, flavor & fragrance, and biotech industries. Its coalescing medium contains a tapered layer-pore structure.
CLG1.0 coalescer filter cartridge(liquid from gas)
CLG1.0 series elements are designed to condense very fine liquid particles (droplets mainly composed of water, oil, and hydrocarbons) in natural gas. The filter element filters solid particles and liquid mist more efficiently.
CLG2.0 coalescer filter cartridge(liquid from gas)
The CLG 2.0 coalescing filter element is an inside-out flow high-efficiency filter capable of removing both liquid and solid contaminants. The filter media can be made of glass fiber, polyester, or polypropylene to meet different filtration needs.
