炼油厂低温热水系统分布在炼油厂各个装置、原油罐区、生活区等地方。在装置日常运行中 ,常有油品泄漏到低温循环热水中 ,对正常生产造成影响。判断泄漏部位常用的方法是测定热水中油的馏程和密度 ,来猜测泄漏油属何种油。此法分析需要一定量的油样 (1 0 0ｍＬ)。一般方法是放
Refinery low-temperature hot water systems are located in various installations, crude oil tank areas, living areas and other places in the refinery. In the daily operation of the device, it is common for oil products to leak into the circulating hot water at low temperature, which will affect the normal production. The common method for determining the site of a leak is to determine the distillation range and density of the oil in the hot water to guess what type of oil is leaking. This method requires a certain amount of oil sample (100mL). The general method is to put
