Dense phase is a favorable condition for transporting carbon dioxide (CO2) and natural gas as well as carbon dioxide injection into crude oil reservoir for enhanced oil recovery. Pipelines have been built to transport CO2and natural gas [1] in the dense phase region due t...
This paper built the forecasting model that can predict the temperature, pressure and flow along natural gas pipeline according to pipe flow equations. Improved Euler method is used to solve these equations. The changes of gas velocity and temperature along pipeline are included to improve the accur...
In this study the coupled pipe-soil vibration model under the pigging action is proposed, and a three-dimensional symmetric pipe-soil vibration finite element model is established through ABAQUS. The influence of the pig running velocity and the friction coefficient of the inner surface on the ...
Whatever the pipeline system, there is the need to determine if the natural gas received at the wellhead has a high sulfur content and a high carbon dioxide content (sour gas), a specialized sour gas gathering pipe must be installed. Sour gas is extremely corrosive and dangerous, thus its ...
The precise measurement of the flow rate of natural gas is of vital economical importance since natural gas contributes highly to the total energy mix. In this paper we report about a laser Doppler velocity profile sensor specifically designed to suit the measurement conditions at the optical test...
Natural Gas Pipe Size app can perform calculations using metric or imperial units. ### Features - Provides required pipe diameter for a pipe section in an instant; - Recommended diameter is displayed as a standard DN or nominal NPS; -
The ultrasonic gas flow meter uses sound waves to establish the velocity of gas flowing in a pipe. At no-flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections are the same. Whereas, when gas… Learn More Vortex Flow Meter A vortex flow meter...
Clean gas with low to medium velocity,used such as biogas flow meter,LPG gas flow meter,nitrogen gas flow sensor. Standard Gas measurement in closed pipe-Turbine flow sensor(GB/T18940-2003) Gas flow meter Size & connection Flange type ...
Thus, velocity calculation requires more pressure and temperature sensors, especially for gas pipelines. Furthermore, if the method is applied to field or long distance pipelines, the time difference calculation requires the data be well synchronized, as presented in Fig. 1. Fig. 1 indicates that...
