Hydrogen sulfide (h2s) leakage and dispersion from a sulfide recycle installation in different wind speeds are simulated by implementing a 3D Computational Fluid Dynamics (CFD) model. h2s concentrations of monitor points which represent dispersion…
A new time-frequency analysis method of Hilbert-Huang transform applied in Pipeline leak detection is proposed. Choosing the negative pressure wave signal from dynamic pressure transmitter as research object, the dynamic pressure signal is decomposed…
In this work, we propose and efficient structure for decision feedback equalization (DFE). The proposed structure makes use of the power-of-two quantization concept to completely eliminate the real multiplications in the DFE's update equations. The…
In the field of transportation of petroleum and its products by pipe line, the 24-inch and 20-inch lines, built by War Emergency Pipelines, Inc., from Texas to the Middle Atlantic Coast as emergency war projects, rank as world record breakers. The…
Important hydraulic characteristics of liquid pipelines and pumps that are necessary to assist the power engineer in evaluating optimum drive characteristics are reviewed. Typical pipeline pumping stations are developed with characteristic curves at…
AEC Pipelines has expanded the capacity of its bitumen blend Cold Lake pipeline from 130000 barrels/day (bpd) to 185000 bpd by the installation of a new midpoint booster pump station utilizing a 3500 HP adjustable speed drive. The unit is a variable…
The installation and use of a 3500 HP adjustable-speed drive on a crude-oil/natural-gas pipeline is described. The unit presented is a variable-frequency induction motor drive using gate turn-off thyristors. It increased the capacity of the pipeline…
