New Methods of Natural Gas Adjusting for Technological Purposes Based on Modern Filtration Materials

Abstract

Reservoir gas treatment technologies currently in use require significant investments in equipment and materials. Considering the foregoing, new technologies are sought for treatment and separation of components of extracted gas. They will guarantee compliance with gas quality requirements arising from applicable standards while at the same time lowering the costs of investment, service and environmental protection. Therefore, the purpose of this work was to develop an efficient mobile technology for natural gas treatment, on the basis of advanced filtering and coalescing materials and membranes, which eliminate the existing, economically non-viable processes and reduce the costs related to development of new reservoirs. The purpose of designed materials was removal of solid particles, water, higher hydrocarbons and nitrogen from natural gas. Presented integrated filtration and membrane system, characterized by a highly compact design enabling installation in container stations and transporting the system between specific points of production.

Material and Process Tests of Heterogeneous Membranes Containing ZIF-8, SiO2 and POSS-Ph

“…Gas mixture separation processes are carried out by a number of methods, including absorption [5,6], adsorption [7,8], cryogenic techniques [9,10], molecular screening [11,12] and membrane techniques [13][14][15]. Naturally, each of these methods has its advantages and disadvantages.…”

High filtration efficiency fluffy material: nano-fiber constructing gradient structure on recycled curved PET micro-fibers web

“…In order to decrease airflow resistance while keep the high FE, an ideal filtration material is elaborately designed with a kind of gradient structure which provides an effective surface area inside filtration materials [14]. On the other hand, the structure facilitates the pressure gradient, improves FE and reduces the airflow resistance [15][16][17][18][19][20]. Micro/nano-fibers, nanoparticles and multi-layer hybrid structure are used for the designing of the gradient structure.…”
