摘要

由于风或降水的天气冷却作用，未隔热的近大气层储罐顶部气体空间中的蒸汽会收缩和冷凝。最新版本的 API 2000 和 ISO 28300 标准建议对非隔热储罐进行工程审查。如果使用最先进的文献模型进行审查，则顶层空间会被假定为蒸汽饱和状态。在本文中，作者首次提出了一种方法，用于解决近大气压储罐中部分饱和单组分顶部空间的热吸入问题。通过与公开文献中涉及饱和封头空间储罐的现有测量结果进行比较，可以推断出这种简化方法倾向于最大限度地减少对透气要求的过高估计。

Breathing of partially saturated headspaces in near-atmospheric storage tanks

Vapors in the gaseous headspaces of uninsulated near-atmospheric storage tanks contract and condense due to weather cooling by wind or precipitation. The latest editions of API 2000 and ISO 28300 standards recommend engineering reviews for uninsulated hot tanks. If those reviews are performed using the state-of-the-art literature models, headspaces are assumed saturated with vapors. However, vapors in the headspaces of tanks with frequent turnovers are seldom saturated, and condensation may be overestimated.

In this paper the authors present the first method to address thermal inbreathing of partially saturated single-component headspaces in near-atmospheric storage tanks. The comparison with available measurements from the open literature involving tanks with saturated headspaces infers that this simplified approach tends to minimize overestimation of the inbreathing requirements.

期刊介绍： The broad scope of the journal is process safety. Process safety is defined as the prevention and mitigation of process-related injuries and damage arising from process incidents involving fire, explosion and toxic release. Such undesired events occur in the process industries during the use, storage, manufacture, handling, and transportation of highly hazardous chemicals.
