安庆石化新检测手段保障LPG产品无争议出厂
安庆石化 LPG产品 液化石油气 中国石化
2023/4/29
为提高检验分析准确度、分析效率，保障液化石油气（简称LPG）产品无争议出厂，安庆石化积极探索，使用改进的烃组成分析进样方式，采用替代的硫检测方法，目前已完成2500余罐次的高效分析。
为了确定管道泄漏参数对泄漏过程的影响规律，基于管道开裂面积，结合管道和输送介质的基本性质，以编制的计算模拟软件为基础，进行管输LPG泄漏扩散模拟研究。采用控制变量法，将开裂孔口形状简化为圆形，改变孔径从而改变开裂面积，研究不同开裂面积下LPG泄漏规律。研究结果表明，开裂面积越大，泄漏持续时间越短，泄漏过程中初始泄漏速率就越大，且达到平缓泄漏所用的时间越短。

地下罐 泄漏 渗流 数学模型
2013/6/20
研究液化石油气（LPG）埋地储罐泄漏、LPG渗流扩散的影响因素对其事故的预防、预测、应急等具有重要意义。为此， 分析了导致LPG埋地储罐泄漏的影响因素，重点对LPG在渗流扩散过程中的影响因素进行分析，利用CFD（Computational Fluid Dynamics）模型对LPG在各种地下环境中的渗流扩散过程进行数值模拟，讨论渗透率、孔隙度、水饱和度、重力、扩散到外界环境的出口位置等因素对LPG...
随着我国汽车保有量的不断增长，汽车尾气排放污染已成为城市的重要污染源，而使用LPG（主要成分是C3H8和C4H10，我国的LPG中C4H10含量比较大）则可大大降低污染。对电喷发动机上分别使用汽油、纯C3H8和75% C3H8+25%C4H10三种燃料进行了对比试验。结果表明：与汽油燃料发动机相比，尽管C3H8燃料发动机的功率下降11%、转矩下降7.3%，75% C3H8燃料发动机的功率下降5.8...
随着我国国民摩托车保有量的不断增长，摩托车尾气排放污染已成为城市机动车排气污染的一个不容忽视的部分。减小摩托车排气污染的理想清洁燃料首选LPG。为解决摩托车LPG发动机动力性下降的问题，分析了LPG的物化特性，并进行了LPG进气道气态喷射、进气道液态喷射和缸内液态直接喷射的对比试验。结果表明，液态LPG缸内直接喷射发动机的最大扭矩较燃用汽油时提高约10%，能有效解决LPG常规供应方式发动机动力性下...
