Modelling and optimization of an existing onshore gas gathering network using PIPESIM.

Pakistan has limited natural gas reserves, and most are found onshore. This article reports on the problems of an onshore gas gathering network (GGN) analysed through steady-state simulation modelling using PIPESIM software. The research methodology incorporates a comprehensive steady-state hydraulic analysis considering fluid flowing velocity limitations, liquid holdup and slugging along with other issues faced by gas gathering networks.

Analysis of processed natural gas injection on hydrate formation in high pressure refrigerated condensate lines.

Natural gas and condensate are exposed to hydrates formation at high pressure and low temperature in the presence of traces of water. Hydrates formation results in blockage of pipelines and equipment leading to plant shutdown and production losses. This study intends to find a novel hydrate prevention process for high pressure refrigerated condensate (HPRC) lines.

Numerical Simulation of the Performance of SbSe Solar Cell via Optimizing the Optoelectronic Properties Based SCAPS-1D.

Antimony trisulfide (SbSe), a non-toxic and accessible substance, has possibilities as a material for use in solar cells. The current study numerically analyses SbSe solar cells through the program Solar Cell Capacitance Simulator (SCAPS). A detailed simulation and analysis of the influence of the SbSe layer's thickness, defect density, band gap, energy level, and carrier concentration on the devices' performance are carried out.
