MOSCOW (MRC) -- EXERGY, a leading provider of new-generation organic rankine cycle power plants, has been awarded - through its parent company Nanjing TICA Thermal Technology - a new contract for the development of a 5.8 MWe waste heat recovery project in China. The final customer is Jiangyin Xingjia New Material Co., a company engaged in the chemical industry, manufacturing purified terephthalic acid (PTA), polyester fiber, polyester film, synthetic resin, according to Hydrocarbonprocessing.
EXERGY’s contract includes the engineering and supply of two ORC units, 2.9 MWe each, that will be part of the new customer’s investment in a greenfield polyethylene terephthalate (PET) production facility located in Jiangyin, in the Jiangsu Province.
The waste heat recovery system will exploit the exhausted low-pressure steam, generated from the PET manufacturing process, to feed an efficient ORC cycle utilizing the radial outflow turbine technology and a non-flammable refrigerant as working fluid. The project will be completed by the end of 2022 and once in operation it will produce a total of 5.8 MW of clean electricity and help save the emission of approximately 17,000 tons of CO2 and the consumption of 8,500 tpy.
We remind that, as MRC reported before, on 21 January 2021, Fujian Baihong Petrochemical started up its new PTA line at Jinjiang, China. The new line with the capacity of2.5 million mt/year of PTA was running at half of its capacity after the start-up.
We also remind that Hengli Petrochemical (Dalian) Co. Ltd. is expected to lead the global planned and announced PTA capacity additions during the period 2019 to 2023, contributing around 22% of the global growth by 2023. Hengli Petrochemical (Dalian) Co. Ltd. is expected to add a capacity of 5.00 million tonnes per annum (mtpa) from two planned projects by 2023.
PTA is used to produce PET, which is used in the manufacturing of plastic bottles, films, packaging containers, in the textile and food industries.
According to MRC's ScanPlast report, the estimated PET consumption in Russia increased to 56,960 tonnes in September 2021, up by 10% year on year. Russia's overall PET consumption reached 592,560 tonnes in the nine months of 2021, up by 12% year on year.
