(PX) (PTA)
According to the law of equimolar ratio, the theoretical consumption of PX in PTA production can be calculated:
Theoretical consumption of PX/molecular weight of px (106) = 65438+PTA/molecular weight of PTA (166)
That is, the theoretical consumption of PX = 106/ 166==0.639, the actual consumption of PX is mostly around 0.65-0.66, the consumption of China's180,000-ton plant is 66.5 million tons, and the consumption of 225,000-ton PTA plant is lower than that of 80,000-ton plant, South Korea and Taiwan Province Province.
Raw material cost of PTA =0.655×PX. There are three kinds of PTA packages: one is 1 ton package, the other is 1.05 ton package, and the other is 1. 1 ton package. The cost of a packaging bag is generally 45-50 yuan. If it is packed by 1 ton,
Each packaging bag is calculated by 53 yuan/ton, that is, the packaging cost of PTA is in 45 yuan/ton. 7. The unit product maintenance and management costs are expected to be around 60 yuan/ton.
8. Total pre-tax cost of 8.PTA production: 0.655×PX price+1000.
Cost comparison between 90.53 million tons of new PTA project and foreign and domestic small and medium-sized PTA plants.
The average cost of PTA imported from abroad to China is about 0.655×PX price+130 USD/ton.
The direct processing cost of producing one ton of PTA in foreign PTA plants is generally $45/ton. Generally speaking, a PTA plant with a foreign investment of1530,000 years has a total investment of about 250 million US dollars, and the depreciation of unit products is about 43 US dollars/ton according to 10 years. If the financial cost is calculated according to the debt ratio of 60% and the average annual interest rate of 4%, the financial cost per unit product is about 1655. However, the freight and miscellaneous fees of foreign PTA imported to China are mostly 20-50 USD/ton, with an average of about 30 USD/ton, so the production cost of foreign PTA is mostly about 0.655×PX price+130 USD/ton, and the tax cost is mostly about 0.655×PX tax-included price+1350 yuan/ton.
The average cost of small and medium-sized PTA plants in China is about 0.655×PX price+1200 yuan/ton.
China's processing costs (including auxiliary materials costs, utilities, financial expenses and depreciation) are generally around 1.200 yuan/ton (both Jinshan and Jinan are 1.200 yuan/ton). If the processing cost of PTA is not included, it is about 8-840 yuan/ton (800-654.38+0 million tons). The annual depreciation of PTA production capacity in China is 29 million yuan.
Therefore, the newly-built 530,000-ton PTA project has more cost competitive advantages than domestic small and medium-sized PTA plants and foreign imports.
