This study aims to shed light on natural gas as an important and promising energy source. This energy source is the fastest-growing source in the world due to the increasing global demand. In this paper, the rates of growth in global demand for natural gas according to the latest reports since 1984, as well as the gas specifications required for transport and storage, acid gases, including absorption, desorption, Cryogenic and separation by membranes, are discussed with the advantages and disadvantages of each method. Focusing are presented. In addition to the primary treatment processes that take place on the gas, the most important of which is the removal of acid gases. Processes for removing on the membrane separation process as the most promising process in this field and reviewing all the research that is discussed in details of this process.

Engineering and Technology Journal, 2017, Volume 35, Issue 1, Pages 33-36

In this research was the study of the impact of silver nanoparticles solution on the structure and properties of the morphological membrane fibrous hollow PVDF through a dip PVDF Hollow fiber membrane in silver nanoparticle solution preparation via using laser ablation method. The characteristics of membrane and silver Nano particle solution and was examined using X-ray diffraction (XRD)and Scanning Electron Microscopy (SEM) also using laser particle size analyzer for Silver nanoparticles (AgNPs ) to measurement particle size to AgNPs.

Membranes have gained an important place in chemical technology and are used
in a wide range of applications. This investigation has studied the effect of operating
conditions such as temperature, trans-membrane pressure and solute concentration
on the separation performance of (PVC/ PS) hollow fiber membrane, which was
prepared in the laboratory from 15% (PVC) and 2% (PS) using phase inversion
method. An attempt was done to investigate the ability of PVC/PS hollow fiber
membrane for ultrafiltration application. A (PVP) solute was used to measure (PVP)
rejection of prepared membrane.
The predicted flux was found to increase from (18.88 l/m2.hr) to 33.05 l/m2.hr)
when the operation temperature was increased from (10Ž) to (30Ž).While it
increased from (28.57 l/m2.hr) to (263.36 l/m2.hr) when the operation pressure was
increased from (1bar) to (3bar). It was also found to decrease from(17.97 l/m2.hr) to
(12.20 l/m2.hr) with increase solute concentration from (1000ppm) to (2500ppm).
The rejection efficiency was equal to (99.93%) when using (2500ppm) solute. This
is considered within UF range.
