What is the cost of recovering ethane from gas fields, in yuan per ton? What is the relationship between ethane prices and natural gas and propane prices? Personally, I think ethane requires cryogenic separation, so its price should be higher than that of methane and propane. What do you all think?
The price of ethane is largely influenced by supply and demand; gaseous ethane is transported to ethylene plants, creating a buyer’s market.
The natural gas ethane recovery unit requires few additional devices compared to the LPG recovery unit, and the degree of refrigeration needed is not significantly increased either. The additional investment and operating costs are low. Its price is sometimes higher than that of LPG and sometimes lower, but it is definitely higher than that of natural gas; otherwise, there would be little point in carrying out such recovery. At present, multiple such units are in the design and construction phase at various oil fields operated by CNPC.
