Contract made for the latest DeNOx systems that meet new environmental standards 2018-11-28





Sae-A STX Entech, a leading global EPC company, announced that it has won a contract for DeNOx systems at POSCO's Pohang and Gwangyang steam power plants. DeNOx systems are the auxiliary facilities for removing nitrogen oxides that occur during thermal power generation, and are now in the limelight due to their role in enabling facilities to comply with special measures for fine dust management that have emerged as a social issue since 2016. In particular, the facilities must be added to steam power plants that produce electricity with steam energy through thermal energy.


The contract, which will build a total of 15 DeNOx systems including 6 units in Pohang Power Plant and 9 units in Gwangyang Power Plant, will amount to 30 billion won in total. As a result, the two power plants will be capable of purifying nitrogen oxides that occur when they produce about 1,400MW of electricity. Along with road traffic, a thermal power plant is considered a major source of nitrogen oxides. It directly stimulates the respiratory system, causes cardiovascular disease, asthma, metabolic disease, and indirectly affects 50 percent of ultrafine particles (PM2.5) formation. According to a study by the University of California in the USA, reduction of nitrogen oxides by one ton would reduce 0.13 percent of fine dust in the atmosphere.


Since Sae-A STX Entech, divided from STX Heavy Industries and established in last August, joined the Global Sae-A Group and graduated from court receivership, it enjoyed the excitement of winning its first order after normalizing its management.


EPC is an acronym that is made up of the first letters of Engineering, Procurement, and Construction. Such EPC projects are implemented on a "turn-key" basis as a contractor who has won a large-scale construction or an infrastructure project provides the above three processes collectively. Even during the period of court receivership, Sae-A STX Entech has been considered a strong player in the industry, by winning contracts for EPC projects both home and abroad, including the Buk-Pyeong Thermal Power Plant and Iraqi Power Plant, etc.
