Studying the Possibility of Replacing Petrochemical Products with Natural Gas in Public Transport Sector(In case of the taxis of the city of Tehran )

The rapid increase in petrol consumption in years, as well as the current restrictions regarding meeting the increasing demand for petrol with production or via import, has made executive officials, including the Ministry of Oil, warn about the current trend. They have announced that if the current situation goes on, we will be faced with a crisis. Meeting such a demand is not possible both technically and financially, and we will soon encounter a dead lock situation while the increasing import of petrol is a burden to the annual budget. The availability of rich resources of natural gas in the country as an alternative to petrol to be used in public transport has made this issue one of the priorities of the energysector. The were five scenarios assumed for the plan and the plan was studied in terms of whether or not implementing the plan would be economically beneficial in either of those scenarios. The current study analyzed the scenario in which the modification the taxis of Tehran(into running on natural gas) has been taken into consideration. Model results were analyzed according to the main scenario and the results showed that replacing natural gas with petrochemical products in the public transport is considerably beneficial, and that such a plan is economically justifiable.
