Method of cleaning of gases and sulphur-bearing gas extraction

Invention relates to removal of sulphur-bearing gases from unrefined gases. Note here that removed sulphur-bearing gases are processed gases at high regeneration pressure. This allows the feed of sulphur-bearing gases into storage with lower costs for compression. Unrefined gas is fed to absorption tower to it to be cleaned of sour gas components with the help of physical absorbent. Absorbent saturated with sulphur-bearing gases and those suitable for use is, then, fed in high-pressure stripping tower for evaporation of the portion of absorbent and production of extraction steam. Extraction steam is used for separation of co-absorbed gases suitable for use. The latter are output from high-pressure stripping tower top end. Absorbent contained in vapours of stripping tower top end is liquefied and derived back into high-pressure stripping tower. Absorbent flow from bottom end of said tower is fed to high-pressure regeneration tower for separation of sulphur-bearing gases and derivation at high pressure in regeneration tower top end. Regenerated absorbent is derived from said bottom end into absorption tower.

Magnetically controlled sorbent agent for bilirubin elimination from biological fluids

Invention refers to medicine and is applicable for treating endogenous intoxication caused by high plasma bilirubin concentrations accompanying various pathologies. Substance of a method: a surface of a magnetically controlled sorbent agent is coated with hydrophobic ligands either in the form of 3-mercaptopropionic acid methyl ester, or in the form of polymeric octadecylhydrosilicic acid, or in the form of polymeric hydrosilicic acid, containing covalently attached octadecyl ligands. Magnetite micro- and nanoparticles are presented by Fe3O4. The total bilirubin recovery rate in the sorbent agent is determined by a lyophilised bovine serum dry powder. The bilirubin content is determined by formula: AB(%)=100-(A460 nm test/A460 nm reference)×100, wherein AB(%) is a percentage of the absorbed bilirubin; A460 nm test is an optical density of the solution contacted the sorbent agent; A460 nm reference is an optical density of the solution before contact with the sorbent agent; 460 nm is a wave length whereat bilirubin has the maximum optical absorption.

Method of producing adsorption element

Invention relates to methods of producing an adsorption element. The method includes preparing a starting composition of a crystalline adsorbent selected from zeolite, silica gel or a combination thereof, mixing with a polymer binder in form of polymers of fluorinated derivatives of ethylene. A rheological additive is added to the obtained mixture. The suspension of adsorbent powder and the polymer binder in the rheological additive is moulded into a raw article of given shape. The raw moulded article is either subjected to heat treatment in a vacuum or is exposed to a microwave field until the rheological additive is removed. The end surfaces of the adsorption element are then coated with the suspension of the adsorbent and the polymer binder in the rheological additive or the rheological additive and the adsorption elements are exposed under normal conditions in an air atmosphere. The end surfaces of at least two adsorption elements are brought into contact and the point of contact is either subjected to heat treatment or is exposed to a microwave field.
