Title:
MULTI-PHASE FLOWMETER
Document Type and Number:
WIPO Patent Application WO/2008/050522
Kind Code:
A1
Abstract:
In order to extract a part of three-phase flow from a pipe line (23), a pair of communication pipes
(13), which are connected to upper and lower streams of an orifice (12) provided in
the pipe line (23), and a gas-liquid extraction tank (14) are used. The flow of
slag stream or the like into the pipe line (23)causes a periodical change in a pressure
difference between before and after the orifice (12). This causes the extraction
of gas and liquid and the discharge of mainly gas to be simultaneously carried
out in the pair of communication pipes (13) and the gas-liquid extraction tank
(14). In the gas-liquid extraction tank (14), the gas and liquid are forcibly shaken,
for example, leftward, rightward, upward, and downward for stirring, whereby
a gas-liquid mixture, in which the proportion of the liquid phase is higher, stays.
The mixed liquid is extracted to remove gas from the gas-liquid mixture in which
the proportion of the liquid phase is higher, followed by storage in a liquid storage
tank (17). The mixed liquid in an amount necessary in a coriolis meter (38) is
flown from the liquid storage tank (17). As a result, in the coriolis meter (38),
the density can be measured with high accuracy.
