South Korea: Daesan Complex To Develop Its Polymer Capacity For Durable Applications The Hanwha Total Petrochemical (HTC) joint venture is commissioning a new polypropylene line at the Daesan integrated refining and petrochemical complex in South Korea, adding a further 60% to its production capacity, which now totals 1.1 million tons a year. At the same time, the start-up of a fourth propane furnace will increase ethylene production capacity by 10% to 1.5 million tons a year. These projects were carried out safely and successfully, and were completed on time and on budget. They mark the culmination of investments totaling $1.3B, announced in 2017 and 2018, to expand production capacity at the Daesan complex. They also take advantage of abundant, cost-advantaged propane feedstock from the United States.
