Grasys has unrivalled experience in development and manufacture of air and gas separation equipment. In engineering and scientific developments our specialists lean against the experience gained in equipment operation and new business challenges of our customers. Through this process Grasys is pleased to offer customers equipment that best meets their needs and the use of which results in substantial cost savings.
R&P Co. Grasys is an expert in membrane gas separation. Our profound experience in designing membrane equipment and expertise in technology ensures that the Customer will arrive at the most cost-effective result while enjoying individual approach to resolving gas separation challenges.
Grasys has launched the first manufacturing facility for hollow fiber gas separation membrane elements in Russia. This is unmatched high-tech production, the only one in Russia and the CIS.
Adsorption technology is based on absorbing certain substances by molecular sieves, and thus air mixture separation is ensured.
Exceptional comprehension of adsorption technology enables Grasys to develop high performance PSA generators. We employ the pressure swing adsorption (PSA) technology to produce advanced PSA generators for nitrogen, oxygen, hydrogen purification units, and gas drying.
The principle of air separation using cryogenic plants is based on air liquefaction and its following separation by low-temperature rectification into nitrogen, oxygen (argon, neon, helium, krypton, xenon). A cryogenic plant is a sophisticated technical product that consists of atmosphere air compression and treatment equipment, heat exchangers, fractionation towers, cryogenic pumps, and a host of other things.
Compression is the industrial processing and gas treatment technology serving to increase its pressure using compressor. Compressors are used to compress air, hydrocarbon gases, pure gases, and others.
Grasys offers the Customers both air compressor units and plants in modular design and compressor units for hydrocarbon gas compression.
An effective solution for deep desulfurization of natural and associated petroleum gas. The basic chemical process is technically simple and totally environmentally-green. Desulfurization units convert H₂S into elemental, recyclable, harmless sulfur.
Alkali purification is an assisted technology to be used as a final desulfurization unit to remove residual content, most particularly mercaptans, from gas that has previously been purified from hydrogen sulfide using liquid-phase hydrogen sulfide oxidation technology.
