烯烃干燥3A分子筛 裂解气干燥3a干燥剂 乙烷、丙烷、丁烷 烷烃干燥3A型分子筛

    产品介绍

    概述
    3A分子筛主要应用于烯烃工厂的乙烯、丙烯、丁二烯及乙炔等产品的干燥，采用3A分子筛进行裂解气的干燥，具有严格固定的分子筛孔径，使得所有烃类都不被吸附，而仅仅吸附水，因些再生时没有烯烃的聚合物生成，合分子筛可以长期保持很同的吸水容量，并且吸附床在低压冷却后加压时也不会变热，因而加压后可以立即切换为吸附作业，解决了用活性氧化铝聚合物污染的结果，有时聚合物的污染和积累，造成很大的压力降，必须重新更换干燥剂；以及裂解气经过脱硫、除去重烃类和压缩之后的深度干燥；在工业油脂脱水中采用3A分子筛可以得到其他干燥方法很难达到的脱水深度。许多天然气涤气装置都采用解吸油来回收乙烷、丙烷和丁烷，为了更加完全的回收这些物质，现在广泛采用低温涤气。但是在15度以下，解吸油中的水分很容易与烃类生产水化物，将系统堵塞。因些采用解吸油需要经常脱水，使水含量降到15PPM以下。用3A分子筛双床干燥装置可以充分满足这种要求，一般操作循环周期为8-24小时。

         我公司生产的3A分子筛的孔径为3A，主要用于吸附水，不吸附直径大于3A的任何分子，根据工业上的应用特点，我们生产的分子筛具有更快的吸附速度、更多的再生次数、更高的抗碎强度及抗污染能力，提高了分子筛的利用效率并延长了分子筛的使用寿命，是石油、化工行业中气液相深度干燥、精炼、聚合所必需的首选干燥剂。
