at the Taoyuan Refinery, completed in 2008; a 20,000-barrel-per-day cracked gasoline dydrodesulfurization plant at the Dalin
Refinery, completed in 2009; a 40,000-barrel-per-day diesel hydrodesulfurization plant at the Dalin Refinery, completed in 2010;
and relocation of the 18,000-barrel-per-day cracked gasoline quality improvement plant from the Kaohsiung Refinery to the Dalin
Refinery in 2011. All of those facilities duly completed pilot operation and are now in mass production.
Additional facilities include an 80,000-barrel-per-day residue fluid catalytic cracking (RFCC) facility at the Dalin Refinery begun in
2006, which started pilot operation in November 2012, completed performance testing and began mass production in 2013. At
that same location, construction of a 14,000-barrel per day alkylation plant able to take advantage of the plentiful supply of crude
butane feedstock from the refinery's heavy fuel oil conversion facility began in 2008; this plant, designed to boost the quality of
gasoline, duly completed performance testing and began mass production in 2013. In order to eliminate acidic process fumes and
reduce pollutant emissions, CPC constructed a new sulfur plant with a daily output of 250 tons; this plant began producing sulfur
meeting the required quality standards during pilot operation at the end of June 2014. To meet the increased need for low-sulfur
fuel oil feedstock following operation of the heavy fuel oil conversion facility at the Dalin Refinery, CPC is planning to build a third
heavy fuel regenerated hydrodesulfurization plant, with investment slated for March 2017.
