PTT Public Company Limited (PTT), a Thai state-owned oil and gas company and one of the country’s biggest corporations, has commenced a 15-year project to purchase compressed biomethane gas (CBG) from Universal Adsorbents & Chemicals (UAC) for supply to two refueling stations in Chiang Mai, commencing 2012 according a report by The Nation. “If this works commercially, PTT may expand the volume purchased from UAC in order to reduce NGV imports,” Punnachai Footrakul, vice president for NGV marketing at PTT is quoted as saying.
Akkapon Pinkaew, Engineer for PTT’s NGV Business & Product Development Division, confirmed to NGV Global that UAC will be purifying biogas from dung and wastewater from Mongkol and Sons pig farm in Chiang Mai. After purification onsite, the biomethane gas will be transported by truck to the refueling stations, approximately 50 kms away.
Plant construction is expected to commence in May, at a cost of THB 100 million (USD 3.34 million). Once commissioned the plant is expected to produce 6-8 tonnes per day, or 3,000 tonnes per year, reported to be enough to fill 500 compact cars or 40 transportation trucks. The biomethane could replace diesel imports of 2.2 million litres per year or liquefied petroleum gas (LPG) imports of 1,600 tonnes, which would save the country Bt21 million (approx USD 700k) .
Kitti Jivacate, president and CEO of UAC, said talks were underway with two companies to cooperate in a similar new project in the South.
