Recently, the dimethyl succinate tower of the 120,000-ton-per-year 1,4-butanediol unit in the Qingyang Tongxin 500,000-ton-per-year light hydrocarbon deep processing project, undertaken by the Northwest Branch of China National Chemical Engineering Sixth Construction Co., Ltd., was successfully hoisted. PriceSeek analysis of 1,4-butanediol, with a long-short rating: -1.5. The successful hoisting of the project indicates smooth progress in the construction of 1,4-butanediol production capacity, with expectations of an additional 120,000 tons per year of new supply in the future, which may exert downward pressure on spot market prices. Considering the current market supply and demand, capacity expansion will intensify competition and limit upward price potential, thus warranting a generally strong bearish rating.
