Title:
METHOD FOR OPERATING FLASH VESSEL
Document Type and Number:
WIPO Patent Application WO/2013/105453
Kind Code:
A1
Abstract:
If the height from a slurry outlet (4) of a flash vessel (10) to a managed liquid level position (S) is denoted as H1, the height from the managed liquid level position (S) to the top of the flash vessel tower is denoted as H2, and the diameter of the flash vessel (10) is denoted as D, 0.35D ≤ H1 ≤0.45D and 0.75D ≤ H2 ≤ 0.85D, and at the managed liquid level position (S), the slurry liquid level (8) is detected by at least one liquid level sensor (21), a slurry discharge valve (16), which is installed on a slurry discharge pipe (14) that leads out from the flash vessel (10), is opened when the liquid level sensor (21) detects that the slurry liquid level (8) has risen, and is closed when the liquid level sensor (21) detects that the slurry liquid level (8) has dropped. Appropriate valve opening and closing control is thus implemented, reducing troubles with a steam discharge pipe, the slurry discharge pipe, and the slurry discharge valve.
