May I ask what the cost of producing vinyl acetate using different processes is approximately?

All I know for now is that when the price of vinyl acetate monomer (VAM) reaches 5,600–5,900 yuan per ton, it has dropped below the cost threshold for all domestic enterprises that use the calcium carbide process as well as those that use the natural gas process; it is also approaching the cost level of enterprises that use the ethylene process. In that case, the calcium carbide-acetylene method must be the most costly. The cost of the natural gas-acetylene method is likely around 6,000 yuan per ton. So, what is the cost of the vapor-phase ethylene method (used by Nanjing Selenis)? And what are the costs of the ethylene production methods used by Beijing Dongfang Petrochemical Co., Ltd. and Shanghai Petrochemical Corporation? Please advise!
