PTA集装箱的水平灌装工艺

Horizontal Filling Process for PTA Containers

为了使用集装箱内衬袋大吨位装运散装PTA(精对苯二甲酸)产品,灌装问题亟待解决。为此,福建福海创石油化工有限公司自主研发了水平灌装工艺系统。该系统具体操作为:将20GP尺寸的PE内衬袋放置于同尺寸的集装箱中,集装箱水平放置于托架上,通过重力式水平灌装系统的进料管,物料水平进入集装箱尾部,利用PTA粉料的重力产生的流速及其流化特性,实现以水平方式向集装箱内灌装。该系统不仅实现了全封闭作业,还显著提高了灌装效率,有效节省了包装材料,达到了低碳环保的效果。据统计,每吨PTA能节省包装成本和运输成本约60元,经济和社会效益显著。

In order to transport bulk PTA(purified terephthalic acid)products in large tons using container liner bags,the issue of filling needs to be addressed.To this end,Fujian Fuhaichuang Petrochemical Co.,Ltd.has independently developed a horizontal filling process system.The specific operation of the system is to place a 20GP sized PE liner bag in a container of the same size,place the container horizontally on a rack,and use the feed pipe of the gravity based horizontal filling system to horizontally fill the material into the rear of the container.By utilizing the flow rate and fluidization characteristics generated by the gravity of PTA powder,the material is filled into the container in a horizontal manner.This system not only achieves fully enclosed operation but also significantly improves filling efficiency,effectively saving packaging materials and achieving low-carbon environmental protection.According to statistics,it saves approximately RMB 60 per ton of PTA in packaging and transportation costs,resulting in remarkable economic and social benefits.
