Alternatives for Natural gas Transmission from South-Pars Gas Field to India, NGH, CNG and PNG

The worldwide consumption of natural gas is rapidly increasing. It is predicted the natural gas demand increases at an average rate of 2.4 percent annually until 2030 in the world. However this rate of increase is higher for some countries with fast growing economy like India. To satisfy such a demand, there are some plans to transport natural gas from south pars gas field, the largest Iran's natural gas field, to India. There are many possible technologies for transporting gas from production fields to consuming markets. These technologies include pipelines (PNG), Liquefied Natural Gas (LNG), Compressed Natural Gas (CNG), Natural Gas Hydrates (NGH), Gas to Liquid (GTL), Gas to Commodity (GTC) and Gas to Wire (GTW), i.e. electricity. Gas transmission projects are sensitive to technology selection and depending on the capacity and distance; chosen technology may affect the economy of the entire project noticeably. In this work the feasibility of transporting 100 MMSCMD natural gas from port Assaluyeh in southern Iran to India using some alternative technologies such as PNG, CNG and NGH has been investigated. The results show for this case, PNG is the best cost effective method and CNG and NGH are the other options respectively.
