One of the principal issues of air pollution from ships is the oil vapour emission.
船舶装卸运输石油时,油气蒸发是船舶大气污染的主要问题之一。
With compressed air temperature drop, the excess oil vapour condenses into liquid oil, to make the powder coating system problems.
随着压缩空气温度降低,多余的油蒸气将凝结成液体油,从而使粉末涂装系统出现问题。
When oil vapour condenses again, countless minute particle are formed, which are suspended in the air.
当油气再次冷凝时,会形成无以计数的悬浮在空气中的颗粒。
If oil steam affects the system, can use special (very expensive) steam directly from the oil filter in the compressed air to remove oil vapour adsorption.
如果油蒸气影响涂装系统,可以采用特种(非常昂贵)的油蒸气过滤器直接从压缩空气中吸附油蒸气加以去除。
The pollution of oil vapour emitted in loading and unloading of petroleum products and its control technologies are described.
介绍了石油产品装卸过程产生的油气污染及其治理方法、工艺过程与技术特点。
The basic theory, technology and operating process of adsorption and de-adsorption in the oil vapour recycle system is introduced, and then application and benefits of the system is analyzed.
