Optimization of Liquid Seal Device for Drain Systems Containing Sand on Offshore Platforms

Abstract

Abstract:

Drain system is one of the most important systems on offshore platforms. In order to prevent the turbulent flow of combustible gas which comes from different regions, U-tube liquid seal device is often used in open drain pipes. When the drain system contains sand, the U-tube will get clogged frequently and is difficult to clean. To solve this problem, the optimization of U-tube liquid seal device is performed according to the principle of liquid seal. Moreover, a new Y-tube liquid seal device is designed, which is more suitable for drain systems which contain sand on offshore platforms. The Y-tube liquid seal device, with the function of sealing and settling, can easily be cleaned, and provides more advantages than U-tube liquid seal device.

Key words: offshore platform, drain system, U-tube liquid seal device, Y-tube liquid seal device
