Carbon reduction: a 10-year journey for CPC’s Petrochemical Business Division

Carbon reduction: a 10-year journey for CPC’s Petrochemical Business Division


November 2017

The Conference of the Parties 21 (COP21) will replace the Kyoto Protocol when it expires in 2020. It – COP21 - will require participating countries to each submit their own Intended Nationally Determined Contributions (INDC) to carbon reduction as an indication of their commitment to tackling global climate change. To show its determination in this respect, Taiwan’s present government has set the target of reducing greenhouse gas (GHG) emissions to 20% below those of 2005 by 2030. Going further, the aim is to lower annual GHG emissions to 50% of their level in 2005 before 2050.


In seeking to both abide by international climate change protocols and fulfill its corporate social responsibility (CSR) commitments, CPC’s Petrochemical Business Division (the Division) has devoted considerable effort to managing the issues of greenhouse gas emissions, energy saving and carbon reduction. In the decade from 2006 to 2016, the Division passed muster on 47 items in its plans for greenhouse gas emissions reduction that were assessed by the Taiwan Green Productivity Foundation. The resulting accumulated amount of carbon reduction is precisely 610,000 metric tons. This year there are 6 planned items relating to greenhouse gas emissions reduction under implementation: they include renewing the No.4 naphtha cracker tubing; changing the high-efficiency tray in the new No.3 naphtha cracker’s de-propane tower and resetting its ethylene product pump; using waste heat to preheat feedstock for the No.3 aromatic plant; and installing low power-consumption lighting and solar energy generating equipment. The resulting total amount of carbon dioxide emissions foregone will be approximately 7,000 metric tons.


The Division also participates in the corporate cooperation program for greenhouse gas reduction organized by Kaohsiung municipal government, whereby neighboring primary and secondary schools are helped in renewing energy-saving lamps and refurbishing air-conditioning plant. The cumulative amount of energy saved thus far equates to around 19,734 kilowatt/hours (kWh). Additionally, replacing the energy-saving fluorescent lamps in Kaohsiung Public Library’s Linyuan branch is scheduled for this year.


The Division’s plans for greenhouse gas emissions reduction in the future fall into three phases. In the short-term, the focus is on process and equipment optimization and improving energy efficiency; in the medium-term, it will be on accelerating the integration of the respective technologies involving cooling towers, low temperature waste heat and distillation; in the long-term, working towards the replacement of old equipment with new, more energy-efficient plant. CPC will continue to work in alignment with the Government's environmental policy and to be active in implementing carbon reduction measures that counter global climate change – working for the common good of all world citizens.
