• Natural Gas:
Natural Gas is a naturally occurring hydrocarbon gas at low pressure. It’s a mixture consisting mainly of methane. in which Methane the largest proportion of natural gas may account for 85%, 10% for Ethane and smaller amounts of propane, Butane and other gas. Natural gas is widely used worldwide and it provides about 25% of energy in all areas. In Vietnam. Natural gas is a new fuel that supplied to the consumers through the pipelines, has many advantages in terms of technology, environment and economy compared to other traditional fuels.
In terms of technology, Natural gas has high gross heating value, high combustion efficiency, easy adjustment of the combustion chamber temperature, operation / maintenance of the system easily. The gross heating value of natural gas is provided by PV GAS D in the range of 38 to 42 MJ/SM3.
In terms of environment, using Natural gas will reduce the impact of environmental pollution, the content of COx, SOx and NOx in emissions is lower than the emissions generated when burning the same amount of other fuels. In all of the fossil fuels, Natural gas causes the least harm to the environment.
In terms of economic, the price of natural gas supplied by PV GAS D in Viet Nam is more competitive than traditional fuels such as DO, FO, LPG ​​(converted in the same unit of heat). On the other hand, using Natural Gas as fuel will significantly reduce investment costs for storage, tanks and maintenance costs,  as well as increase the life of the equipment.
With above-mentioned advantages as well as capability/gas resources in Vietnam,
PV GAS D has been supplying Natural Gas to industrial consumers not only in Phu My - My Xuan - Go Dau Industrial Zones in Ba Ria - Vung Tau and Dong Nai Provinces, but also other industrial zones in Nhon Trach(Dong Nai Province), Hiep Phuoc (Ho Chi Minh City) and Tien Hai (Thai Binh Province).
  • CNG (Compressed Natural Gas)
CNG (Compressed Natural Gas) is natural gas that is compressed under high pressure (up to 250 barg). CNG is contained in a dedicated tank and transported to the consumer in the tractor (CNG trailer).
CNG has full of the characteristic of natural, including:
CNG has the high gross heating value which in the range of 38-42 MJ/SM3, high combustion efficiency, easy to adjust the combustion chamber temperature, easy to operate/ maintain the system.
In terms of environment, using CNG will reduce the impact of environmental pollution, the content of COx, SOx and NOx in mission is lower than the emission generated when burning the same amount of fuel. In all of the fossil fuels, CNG causes the least harm to the environment.
In terms of economic, CNG supplied by PV GAS D is more competitive than other traditional fuels such as DO, FO, LPG ​​( converted in the same unit of heat). PV GAS D is the leading CNG producers for distribution to customers in industrial zones. On the other hand, using CNG will significantly reduce investment costs for storage, tanks and maintenance costs, maintenance as well as increase the life of the equipment.
  • Maintenance and repair services for gas facility and equipment
    • Carrying out the inspection, maintenance, repair, upgrade and revamp of systems and equipment in the gas transportation, gas distribution, and gas storage systems in gas facilities.
    • Providing technical services for inspection, maintenance, and upgrade of technological equipment, control systems, power supply systems, etc. for gas storage facilities and industrial plants.
    • Conducting the inspection and testing of pressure equipment, tanks, heat exchangers, pipelines, etc.
    • Conducting the calibration, testing, and installation of measuring technology equipment, metering systems, etc.…
    • Conducting the design, fabrication, and installation of mechanical structures, engineering pipelines, tanks, etc.
    • Leasing workshop and specialized maintenance equipment.
Providing equipment, spare parts for replacing chemicals and fuels to be used in oil and gas industry and other industries, etc.
  • Providing Co-generation solutions for city gas sector:

Co-generation system is a system of combined power generators to produce cold water (cold air), hot water, steam, etc. to office buildings, commercial buildings, hospitals, shopping centers, etc. in an urban area.
A co-generation system comprises of: Power generators that use natural gas , heat recovery equipment which recover waste heat from generators, chilling water systems with absorption chillers, hot water supply systems (if needed), steam production system, etc.
In the co-generation technology, natural gas is supplied to the generator to meet local power demand, high-temperature exhaust gas (450-550 °C) will be recovered to produce superheated steam, supplying energy to the generator tank of absorption chillers to produce cold water. On average, waste heat from a 1-MW gas turbine may be sufficient to produce 750RT of cold water or 2.2 ton per hour of superheated steam at 8bar.

Economic benefits: reduce investment costs, save electricity costs, save operating costs and increase system reliability.
Social benefits: improve energy efficiency and environmental friendliness, contribute to promoting the national target program on energy saving and efficiency, reduce load on the grid system, reduce investment in developing energy supply systems, ensure energy security, and protect the environment; Proper exploitation of energy resources and sustainable socio-economic development are factors contributing to the development of city gas market and modernization of the country.

  • LNG (Liquefied Natural Gas): LNG is natural gas which is liquefied after being cooled down to 162oC below zero and removed foreign materials. LNG has mainly methane in its component.

Because it accounts for only 1/600 of the volume of natural gas under standard conditions (15oC, 1 atm), LNG is a convenient gas product for storage and transportation from production facilities to consumption markets in the world. Today, LNG is mainly transported by LNG tanks with capacities ranging from 170,000 m3 to 260,000 m3, in which the most common load being from 155,000 m3 to 170,000 m3.

After being transported to the consumption markets, LNG is recovered to gas state when it passes through gas recycling equipment and then it’s pumped into the pipeline for distribution to the consumers. LNG is used similarly as dry gas to meet the gas demand of power plants, industrial households and urban areas. Currently, in many countries of the world, LNG is also used as fuel for transportation vehicles such as ships, trains and heavy trucks, to minimize environmental pollution.

In addition, LNG can be transported by tankers, trains, coastal vessels with capacities of 2,500 12,000 m3 for distribution to gas consumers, coastal markets, and offshore islands.
