The company has ammonia production capacity is 600,000 tons/year and methanol is 250,000 tons/year. It is divided into two systems and can be operated separately. Due to the upgrading of the ammonia system,the new installations is scheduled to be put into operation in June 2019,and the complete set of ammonia system currently will be sold. Now the equipment will be online auction processing in the near future. Interested parties can contact Mr. Chen +86 13319399057 or Miss Xiao +86 15170039260 to register, and then arrange to see the goods and bid.
