大型塔顶空冷器入口管线柔性设计

Flexible Design of Large-scale Air Cooler Inlet Pipeline Located on Top of the Tower

炼油化工装置的大型化引发的塔顶空冷器入口油气管道设计难以解决的问题,即塔顶油气管道热膨胀导致空冷器管嘴产生过大的作用力。本文介绍了塔与多达16片空冷器之间油气管道的设计,运用CAESARⅡ软件对该空冷器油气管道进行应力分析,提出设置类似π补偿器的独特管线布置方案,结果显示整个管系受力明显改善,空冷器管嘴受力控制在应力要求的范围内,保证了设备的安全运行。

With the upsizing development of petrochemical unit, the design of oil and gas pipelines at the entrance of air cooler located on top of the tower is difficult to be solved, the thermal expansion of the pipelines results in excessive force in the air cooler nozzle. The design of the oil and gas pipelines between the tower and up to 16 of bays air coolers was introduced. The stress analysis of the oil and gas pipelines was carried out by using CAESAR Ⅱ software. It was proposed to set up a unique pipeline arrangement similar to the π compensator, the results indicated the force of the entire pipeline system was improved and the force in the air cooler nozzle was in the controlled range of the stress requirements to ensure the safe operation of the equipment.
