Natural gas processing is the process of removing water vapor, hydrogen sulfide, mercaptan, and carbon dioxide from natural gas. The main equipment includes dehydration unit, desulfurization unit, decarbonization unit, and light hydrocarbon recovery unit.

In addition to absorption and adsorption, membrane dehydration unit is gaining popularity in natural gas dehydration plants. This process involves using semi-permeable membranes to selectively remove water vapor from the gas stream. The membranes allow water molecules to pass through while retaining the dry gas. Membrane dehydration is known for its simplicity, compact footprint, and low energy consumption. It is particularly suitable for small-scale gas processing operations and applications where space and energy efficiency are critical. However, membrane dehydration may not be as effective in achieving extremely low water content levels compared to absorption and adsorption methods.

Natural gas dehydration plants, also known as gas drying units or drying plants, are essential facilities in the natural gas industry. They are responsible for removing water vapor from natural gas to prevent corrosion, hydrate formation, and other issues that can arise during transportation and processing. There are several dehydration processes employed in these plants, each with its own advantages and limitations. Understanding the differences between these processes is crucial for selecting the most suitable method for a specific application.

  The low-temperature BOG first enters the cold box to be reheated to room temperature and then enters the BOG compressor for pressurization. The pressurized BOG enters the liquefaction cold box, is cooled, liquefied, and supercooled in the plate-fin heat exchanger, and returns to the LNG storage tank as an LNG product after throttling for the LNG plant.

The gas decarbonization plant is planned to be powered by mains electricity. The electricity of the natural gas purification device is mainly used for MDEA circulation pumps, instrumentation and control systems, etc. Fuel gas is mainly used for thermal oil furnaces. 

The recovery of light hydrocarbons from associated gas in oil fields is a crucial process in the oil and gas industry. Associated gas, which is often found alongside crude oil, contains valuable components such as natural gas liquids (NGL) and liquefied petroleum gas (LPG). Recovering these light hydrocarbons not only maximizes the value of the gas stream but also helps in reducing greenhouse gas emissions. In this article, we will explore the importance of NGL and LPG recovery from associated gas and the technologies involved in this process.

The LNG process technology has been making significant strides in the natural gas processing industry, with recent developments showcasing the innovative advancements in LNG plant technology. As the demand for natural gas continues to rise globally, the focus on efficient and sustainable LNG processing technology has become paramount. One of the latest breakthroughs in LNG process technology is the development of advanced liquefaction processes that enhance the efficiency and environmental performance of LNG plants.
