Low temperature and deep cooling i子還ndustry - A+K application 資友solutions

The LNG is transported by s學金ea from the origin to the use新場r, where it is received 機短and stored at a receiving station. When些哥 unloading, the LNG is collected b黃得y the ship's deliver什章y pump through the discharge 間好arm and its branch pip暗場e to the main pipe, and through the黃鄉 main pipe to the LNG 市算storage tank. In this proces姐城s, it is usually necessary to畫畫 install flowmeters in the mai湖照n pipe for metering.

Current problems: th綠生e flowmeter used in the early d跳秒esign of the project is a照東 branch force mass flowmeter, but due t身舞o the structural limitations of器對 the mass flowmeter itsel信黃f, the maximum diameter can only b呢和e DN250, and it is ne數美cessary to use multiple paralle慢動l to meet the measuremen爸新t requirements, which will br姐坐ing greater pressure loss and cost inc姐小rease, resulting in economic losses如街 for the owner.

In the flow measurement of l要問ow temperature fluid, gener船相ally avoid the use of木姐 flange sealing structure, be美短cause of the reason 了放of thermal expansion and contraction o現讀f some leakage is di國件fficult to control, a站技nd the structure of the "A+K b很物alance flowmeter" is the throttle個舊 parts and pressure port inte公志gration, the measurement of l章老ow temperature fluid when the whole 不來flowmeter and pipe is weld票是ed, no leakage point, to solve 慢金the problem of the flow meter at金區 very low temperature紅吧 leakage is difficult to control.

Cryogenic fluids are usu筆器ally stored in a saturated state i自兵n an insulated storage vessel. In t高林he transfer, pump pressure, se習遠nd out, start the process舞火, and repeated pressure, p司秒ressure. In this process, the 鐘東extremely low tempera費麗ture fluid in the sat姐裡urated state changes into th也動e supercold state and the boiling 們玩state, and the state i森身s easy to change. Th開路erefore, flowmeter design needs到動 to take measures to 答店avoid or mitigate the impact of 黑家this process.
