India's premier gas firm GAIL India Limited is imitating billionaire Mukesh Ambani-led Reliance Industries Ltd in planning to import ethane from the US to replace natural gas and naphtha as feedstock at its petrochemical plants. "In a bid towards diversification of the feedstock, GAIL is looking to import ethane from ethane-surplus countries with matured export terminal infrastructure through water borne transportation to India and transport it further through GAIL's pipeline systems to demand centres," the company said in a tender document. It sought quotes to hire a very large ethane carrier for 20 years starting mid-2026 for importing ethane from the US. The ship with capacity of 80,000 to 99,000 cubic metres is targeted to take deliveries from US ports of Marcus Hook, Nederland, Morgan's Point or Beaumont and deliver ethane at Dahej or Hazira in Gujarat or Dabhol in Maharashtra. GAIL has a petrochemical plant at Pata in Uttar Pradesh, and is also looking to set up another unit at Usar in Maharashtra. GAIL had to cut down on run rate at Pata after the government diverted gas supplies from the plant to city gas suppliers. This led to its profitability being impacted and so now the company is looking to supplement the feedstock with ethane. Reliance Industreis had in 2014 announced ethane plans in 2014 and started importing the feedstock from the US in 2017. It is importing 1.6 million tonnes per annum of ethane and is using six VLECs for transporting it to India. With ethane replacing propane and naphtha used in ethylene production, Reliance is estimated to have saved about USD 450 million annually. GAIL India explores up to 26-pc equity stake in US
