Not to mention the environmental pollution problem, risks of fire and explosion causing damage to people and properties, the current situation of exhausting traditional fuel sources is also gradually pushing the world to the brink of an energy crisis.
So what is the solution for businesses about an optimal energy source?
With a simple composition that is easy to remove harmful compounds (such as SOx, NOx, CO2, benzene and aromatic hydrocarbons...), CNG when burned reduces emissions of up to 80% of toxic gases into the environment compared to other fuels...
Compressed Natural Gas (CNG) is natural gas with the main composition of CH4 – Methane (88%), colorless, odorless, non-toxic, extracted from natural gas fields or associated gas in the oil exploitation process, going through the treatment to remove impurities and heavy components, and then transported by pipeline to the compressor plant. At the compressor plant, the natural gas is compressed to a pressure of 200 - 250 barg to increase storage capacity, reduce transportation costs. At the consumption place, CNG is reduced to the required pressure (usually below 3 barg) by the PRU (Pressure Reducing Unit).
CNG is our CNG Vietnam’s main product. We provide comprehensive energy solutions, ensuring environmental friendliness, reducing emissions with outstanding performance and maximum cost savings. Particularly, CNG Vietnam’s solutions aim to address the country’s top concerns and are in line with the global trend.
Natural gas is taken from the gas supply system of PetroVietnam Gas Corporation (PVGas) or the gas pipeline system of PVGas D, goes to the compressor station (Phu My compression station - Southeastern region; Tien Hai, Thai Binh compression station - Northern region) with the pressure of 22 barg. Gas flow is controlled by the inlet metering system.
Gas is led into CNG compressor station and compressed from the pressure of 14-22 barg to 200-250 barg and refill the specialized tanks.
The compressors and control systems are designed in compliance with international standards and Vietnam’s standards and regulations ensuring safe operation and tested annually.
The compressor station in Phu My (Ba Ria - Vung Tau) has a capacity of 220 million Sm3/year and the compressor station in Tien Hai (Thai Binh) has a capacity of 110 million Sm3/year.
After being compressed and filled into the specialized tanks (composite, steel) with the tank’s volume of 18-40 m3/tank, CNG is transported to customer’s sites. The tanks and trailers are complied with the strict regulations of dangerous and flammable goods transport.
The tank trucks take CNG to the customer’s sites (PRU), then gas is taken from tank trucks with pressure of 200-250 barg (on trailer) going through PRU system, pressure is reduced by 2 stages (stage 1: pressure reduced to 60 barg, stage 2: pressure reduced to 2-7 barg) to supply customers upon request.
PRU system is designed and installed in compliance with international standards and Vietnam’s standards and regulations, ensuring absolute safety.
From the PRU’s outlet, the gas is piped to the customer’s furnace system.
