摘要:
简单介绍了低温乙烷储罐的相关工艺流程，针对低温乙烷储罐设置了超压呼阀和真空吸阀防止储罐本体超压破坏和真空失稳。依据API 2000—2014《常压和低压储罐放空》和GB 51156—2015《液化天然气接收站工程设计规范》，对低温乙烷储罐在各种工况下产生乙烷蒸发气量及设备运行的补气量分别进行计算，并对可能组合工况流量进行分析，从中选择最大量作为设计依据。计算结果表明，20 000 m3低温乙烷储罐超压呼阀设计质量流量为36 700 kg/h，真空吸阀设计质量流量为3 240 kg/h，火炬系统泄放量为2 414 kg/h。可为低温乙烷储罐的安全可靠运行提供保障，也可为类似液化烃低温储罐设计提供参考。
Abstract:
This article provides a brief overview of the process for low-temperature ethane storage tanks, highlighting the installation of pressure relief valves and vacuum suction valves to prevent damage from overpressure and tank collapse due to negative pressure. Based on the guidelines of API 2000—2014 "Venting Atmospheric and Low—pressure Storage Tanks" and GB 51156-2015 "Code for Design of Liquefied Natural Gas Receiving Terminals", the ethane evaporation rates under different operating conditions and the air replenishment required for equipment operation were calculated. The flow rates under different combined operating scenarios were analyzed to select the maximum flow rate as the design basis. The calculation results indicate that the design flow rate for the pressure relief valve of a 20 000 m3 low-temperature ethane storage tank is 36 700 kg/h, while the design flow rate for the vacuum suction valve is 3 240 kg/h and the venting capacity of the flare system is 2 414 kg/h. These findings not only ensure the safe and operation of low-temperature ethane storage tanks, but also provide reference for the design of similar low-temperature liquefied hydrocarbon storage tanks in the future.
