每一款燃氣發動機對燃氣都會有相關的要求：氣體流量、氣體壓力、含水量、硫化氫及有機硅化物含量等。如果燃氣的特性達不到相關要求，則需要根據燃氣的特性和燃氣發動機的要求對氣體進行預處理。

　　Every gas engine has specific requirements for the gas, including gas flow rate, gas pressure, water content, hydrogen sulfide and organic silicide content. If the characteristics of the gas do not meet the relevant requirements, it is necessary to preprocess the gas according to its characteristics and the requirements of the gas engine.

　　燃氣預處理系統所需主要步驟及組件：

　　Main steps and components required for gas pretreatment system:

　　01. 氣體收集系統

　　01. Gas collection system

　　包括儲氣罐（井）和管道網絡。

　　Including gas storage tanks (wells) and pipeline networks.

　　02. 初步處理

　　02. Preliminary processing

　　包括冷卻和凝結，因為收集的氣體通常溫度較高，所以通過冷卻器降低溫度，使水蒸氣凝結成液態水，可以去除一部分水分。

　　Including cooling and condensation, because the collected gas usually has a high temperature, reducing the temperature through a cooler can condense water vapor into liquid water, which can remove some moisture.

　　03. 過濾

　　03. Filtration

　　過濾和去除顆粒物，使用顆粒過濾器，去除氣體中的顆粒物，防止它們對下游設備造成損害。

　　Filter and remove particulate matter, using a particulate filter to remove particles from the gas and prevent them from causing damage to downstream equipment.

　　04. 脫硫

　　04. Desulfurization

　　使用活性炭或氧化鐵，用于去除硫化氫（H2S），因為硫化氫在燃燒過程中產生有害的二氧化硫（SO2）從而腐蝕設備。如果采用卡特彼勒燃氣發電機組，若氣體H2S在150PPM以上，均需要對其進行脫硫處理。

　　Use activated carbon or iron oxide to remove hydrogen sulfide (H2S), as H2S produces harmful sulfur dioxide (SO2) during combustion, which corrodes equipment. If Caterpillar gas generator sets are used, desulfurization treatment is required for gas H2S above 150PPM.

　　05. 干燥

　　05. Drying

　　使用冷凍干燥機或吸附干燥機，進一步去除氣體中的水分，防止在后續處理和使用過程中產生腐蝕或堵塞。

　　Use a freeze dryer or adsorption dryer to further remove moisture from the gas, preventing corrosion or blockage during subsequent processing and use.

　　06. 去除有機硅

　　06. Removing Organosilicon

　　去除有機硅化合物，使用活性炭吸附，去除有機硅化合物（如硅氧烷），這些化合物在燃燒過程中會生成硅氧化物，導致發動機和其他設備積垢。

　　Remove organic silicon compounds, use activated carbon adsorption to remove organic silicon compounds (such as siloxanes), which can generate silicon oxides during combustion, leading to engine and other equipment fouling.

　　07. 壓縮和增壓

　　07. Compression and Boosting

　　使用羅茨風機，將燃氣壓縮、增壓到所需的工作壓力，以便于進入燃氣發電機組。

　　Use Roots blower to compress and boost the gas to the required working pressure for entering the gas generator set.

　　08. 最終凈化

　　08. Final Purification

　　使用拋光過濾器，進行最后的凈化步驟，確保氣體在進入發電設備前達到所需的純度標準。

　　Use a polishing filter for the final purification step to ensure that the gas meets the required purity standards before entering the power generation equipment.

　　根據需要，選擇以上一種或多種的氣體處理方式。經過氣體預處理過程，獲得能滿足不同發動機需求的氣體成分，使之能在發動機內正常地燃燒。

　　Choose one or more of the above gas treatment methods as needed. After the gas pretreatment process, gas components that can meet the needs of different engines are obtained, allowing them to burn normally inside the engine.

　　通過這些步驟和設備，垃圾填埋氣可以被有效處理，轉化為一種清潔且高效的能源，用于發電或其他工業用途。這不僅有助于減少溫室氣體排放，還能將廢物轉化為有用的資源。

　　Through these steps and equipment, landfill gas can be effectively processed and converted into a clean and efficient energy source for power generation or other industrial purposes. This not only helps reduce greenhouse gas emissions, but also transforms waste into useful resources.
