Na mmalite 1990s, Sinopec ji ihe fọrọ nke nta ka ọ bụrụ ijeri yuan 10 iji webata 3 sets nke 50,000 tons / year caprolactam mmepụta osisi, nke e wuru na Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. na Shijiazhuang Refinery. N'ikpeazụ, ụlọ ọrụ Sinopec weghaara teknụzụ isi nke mmepụta caprolactam - nkwadebe nke cyclohexanone oxime dị ka ihe nrịbama, ma mee usoro teknụzụ ọhụrụ zuru oke maka mmepụta caprolactam green na Baling Petrochemical.
