Converting Natural Gas to CNG: The Process
A multitude of procedures are involved in converting natural gas to compressed natural gas (CNG). The first step is to collect and pre-treat the gas. Natural gas is taken from subsurface deposits and transferred to a central processing plant via pipes. The gas is pre-treated at the facility to eliminate impurities such as water, hydrogen sulfide, carbon dioxide, and other pollutants. This guarantees that the gas fulfills quality criteria and avoids damage to the equipment during compression.
Following pre-treatment, the gas undergoes dehydration. Water vapor is commonly found in natural gas and must be eliminated to prevent corrosion and device problems. Dehydration is accomplished through processes like adsorption or absorption. To eliminate the water vapor, the gas is passed through a desiccant substance such as molecular sieves or glycol.
The gas is ready for compression after it has been pre-treated and dehydrated. Compression is an important stage in the conversion of natural gas to CNG. It entails employing compressors to considerably boost the pressure of the gas. This compression enhances the gas’s energy density, allowing it to be held in smaller volumes. Depending on the needed storage pressure for CNG, the gas is normally compressed to roughly 3,000 to 3,600 psi or higher.
Following compression, the CNG is stored in high-pressure cylinders or tanks designed specifically for gas storage. These storage systems are constructed of reinforced materials that can sustain high pressure. CNG storage cylinders are typically cylindrical in shape and can be installed within the vehicle or at separate recharging facilities. The transportation cylinders are built to resist pressures ranging from 3,000 to 3,600 psi.
When CNG is required to fuel automobiles, it can be dispensed directly from refueling stations’ storage cylinders. Specialized equipment is used at the stations to manage pressure and safely transfer CNG from storage tanks to vehicle fuel tanks. To ensure effective and safe refueling, specialist dispensers are used, which are outfitted with safety precautions and pressure-reducing equipment.
The procedures of converting natural gas to CNG include gas gathering and pre-treatment, dehydration, compression, storage, and dispensing/filling. These procedures ensure that natural gas is filtered, compressed, and stored at high pressure, allowing it to be used as a cleaner-burning transportation fuel.
