日前,四川维尼纶厂成功将老区装置醋酸乙烯(VAC)产品的丙酮含量降至目标值范围。这标志着川维厂VAC装置成功停运硫酸洗涤工序,实现了安全、环保和降本多重目标。硫酸洗涤乙炔是天然气乙炔法合成VAC的第一道工序,也是控制产品中丙酮等杂质含量的关键工序,其间会产生大量的废硫酸。受市场需求和环保要求影响,废硫酸的销
Recently, Sichuan Vinylon Factory successfully dropped the acetone content of VAC products in the old area to the target value range. This marks the VAC plant in Chuanwei plant successfully shut down sulfuric acid washing process, to achieve multiple goals of safety, environmental protection and cost reduction. Sulfuric acid is the first process of acetylene synthesis acetylene VAC synthesis process, but also control the content of acetone and other products in the key process, during which will produce a lot of waste sulfuric acid. Affected by market demand and environmental requirements, the sales of waste sulfuric acid
