April 21, 2024 — On April 21, the first line of Hualu Hengsheng's BDO unit, with an annual capacity of 120,000 tons, was operating stably. The second line, also with a capacity of 120,000 tons, began maintenance on April 8 and is expected to last for 25 days. Chempricehub's analysis of 1,4-butanediol shows a supply-demand score of +1. The article indicates that Hualu Hengsheng's second-line 120,000-ton BDO unit has been under maintenance since April 8 for 25 days, resulting in an approximately 50% reduction in supply (while the first-line 120,000-ton unit remains in stable operation). The tight supply may drive up the spot price of 1,4-butanediol, but the stable operation of the first line partially alleviates the pressure, resulting in a generally moderate positive impact. A score of +1 indicates a generally favorable outlook.
