The Dalin Refinery became operationally independent from the Kaohsiung Refinery in 1996. After expansion, there are 4 offshore mooring buoys as well as large and small wharves for handling both imports and exports, holding the daily capacity of up to 400,000 barrels of crude now. The Taoyuan Refinery came on stream in 1976; after engineering modifications and the addition of the second topping unit, its daily refining capacity now amounts to 200,000 barrels of crude. In 2020, the total of refined products was 8,256 kiloliters of gasoline, 1,715 kiloliters of aviation fuel, 5,558 kiloliters of diesel, 2,245 kiloliters of fuel oil, and 367 kiloliters of LPG.
Taiwan’s increasingly stringent standards of environmental protection are largely in response to the demands of its people out of concern for their quality of life. At the same time, they exhibit increasing demand for a diverse range of oil-derived products and CPC has moved to enhance the quality of those goods and increase their value. Going further, the company has, in recent years, raised the production value of its products by building additional and more technologically- advanced refining facilities such as reforming units, isomerization units, and gasoline/diesel desulfurization plant, an aviation fuel processing facility, together with n-alkane, alkylation and residual fluid catalytic cracking (RFCC) units. CPC also plans to build VDU, SDA units and aromatic hydrocarbon extraction units in order to offer domestic consumers even better products and improve its production efficiency.
High value refining Reduced emissions
In response to the EPA’s call for certain reductions in the area of fuel quality in 2011: of the sulfur content of gasoline and diesel fuel to under 10ppmw, of the
aromatic hydrocarbon content of gasoline and diesel fuel to 35vol% and of the alkene content of gasoline to 18 vol%, CPC constructed a 30,000 barrels per day gasoline pyrolysis and hydro-desulfurization unit at the Taoyuan Refinery by 2008, a 20,000 barrels per day gasoline pyrolysis and hydro-desulfurization unit at the Dalin Refinery by 2009 and a 40,000 barrels per day diesel hydro-desulfurization unit at the Dalin Refinery by 2010. Furthermore, an 18,000 barrels per day gasoline pyrolysis and quality improvement unit was moved in 2011 from the Kaohsiung Refinery to the Dalin plant.
In 2006, CPC began increasing its heavy oil conversion rate by construction of RFCC unit with capacity of an 80,000 barrels per day at the Dalin Refinery and completed its testing and kicked off its volume production in 2013. Olefin produced by the RFCC unit in the Dalin Refinery after completion of the construction can be not only be provided to downstream businesses of the industry directly, but also used as the raw material of alkylated gasoline. CPC completed testing of the unit and kicked off its volume production in the mid 2013; its operation has increased the value of our product and improved gasoline quality. In addition, to cope with the problem of acid gas generated in the production process and reduce the emission of the pollutant, CPC invested in the construction of a sulfur plant with a daily output of 250 tons, which started to produce qualified sulfur products at the end of June 2014.
In addition, CPC carried out an expansion of the No. 3 Hydro-desulfurization Unit at the Dalin Refinery to increase its high-sulfur crude refining capacity which increased from 30,000 to 40,000 barrels per day, lower the cost of crude oil procurement cost and stabilize the quality of the RFCC-unit’s feedstock. The expanded unit began production in March 2017.
