Wet Gas

The article deals with one of the important tasks of modern flow measurement, which is related to the measurement of the flow rate and the amount of wet gas. This task becomes especially important when it becomes necessary to obtain information about the separate amount of the dry part of the gas that is contained in the form of a mixture in the wet gas stream. The paper presents the principle of operation and structure of the invariant system for measuring the flow rate of wet gas, which is based on the combined use of differential pressure flowmeters and Coriolis flowmeters. The operation of the invariant wet gas flow rate measurement system is based on the simultaneous application of the multichannel principle and the partial flow measurement method. Coriolis flowmeters and the differential pressure flowmeter are used as the main elements of the system. The proposed measurement system does not offer applications for gases with abundant drip humidity. The article provides information about the test results of the proposed invariant system. The estimation of the metrological characteristics of the invariant system when measuring the flow rate of wet gas is given. The obtained test results of the invariant wet gas flow rate measurement system are relevant for natural gas production, transportation, and storage facilities.

Aiming at the problems of flare gas flow monitoring on offshore oil platform, a flare gas flow measurement system is designed. This system is integrated in the whole flare control system and reaches the effective monitoring of flare gas flow. Besides it adopts ultrasonic flow-meters for the more accurate flow-meter data and adopts hot-cap method for the realization of being installed without halting production. Results indicate that the design could offshore oil platform improve the efficiency and safety of production in offshore oil platform.

A résume of the theory of fluid flow measurement is given in a concise manner. The statistical method of evaluating overall system accuracy is discussed and the standard deviation values for various sources of error are quantified. The results of calculations using the formulae and quantitative data are presented graphically to indicate the accuracies for different methods of measurement at different rates of flow. Other likely sources of error are discussed.

Static Conditions

In this paper, 16–pairs of ultrasonic sensors have been used. The system is capable of visualising the internal characteristics of liquid and gas flow, and provides the concentration map of the corresponding liquid and gas flow. The investigations were based on the transmission and reception of ultrasonic sensors that were mounted circularly on the surface of test pipe. Three experiments were carried out on the test pipe to simulate the horizontal flow of liquid (water) and gas (air) with three static conditions. The results showed that as the distance between the transmitting sensor and receiving sensor increases, the ultrasound will consume a longer travel time to reach to the target. Keywords: Ultrasonic, ultrasonic tomography, liquid and gas flow, flow measurement system
