In Hong Kong, town gas is produced at two production plants. Major supplies of 98% come from the Tai Po Plant, with the Ma Tau Kok Plant making up the rest.
The Tai Po Plant is located in the Tai Po Industrial Estate, covering an area of 11.71 hectares. It has a maximum supply capacity of 9.6 million standard cubic metres of gas a day.
What is Town Gas?
Town gas, produced from naphtha and natural gas, is a clean, safe and reliable gaseous fuel. With about half the density of air, it rises and will dissipate in the air if leakages occur. A special odour has been added to town gas so that it can be detected easily.
