中化新网讯 近日，标普全球大宗商品洞察烯烃与衍生物部门主管乔伊斯·李表示，尽管聚对苯二甲酸乙 二醇酯(PET)需求强劲，有望长期支撑乙二醇市场实现稳定增长，但短期内市场仍需消化新增产能，才 能逐步迈向供需再平衡。与此同时，政策面的波动预计将进一步加剧目前供过于求的局面，给乙二醇价 格带来下行压力。 乔伊斯·李表示，近年来，乙二醇年新增产能持续超过需求，导致工厂平均开工率降至60%以下。目 前，产能增速是需求增速的两倍。要恢复至约80%的正常开工率，2030年前恐难以实现。2019年的乙二 醇市场，北美、中东和中国呈三足鼎立之势，占比相当。但过去五年间，中国成为产能扩张的主要推动 力，目前其产量已占全球总量的一半。近期变化推动中国乙二醇自给率从不足50%提升至75%以上。随 之而来的是中国乙二醇进口总量大幅下降。关于乙二醇可变成本曲线，乔伊斯·李指出，中东和北美地 区采用乙烷作为原料的生产商，其生产成本最具竞争力;紧随其后的是中东、北美及中国生产商。 由于供过于求的局面预计将持续，标普旗下的普氏能源资讯估计，北美地区运营乙烷裂解装置的生产 商，可能要到2027至2028年才能接近盈亏平衡点。而东北亚和西欧地区的 ...
