Compressors convert mechanical energy into pneumatic energy through compression. Pistons, vanes, and other mechanisms are used to compress air and gas, by increasing the pressure from initially lower pressure to higher pressure. Both compressed air and compressed gas are used for various purposes in the manufacturing, petroleum, chemical, power, mining, food and beverage, pharmaceutical, and medical industries. Compressors can be categorized into several types based on functionality and design. However, the major types of compressors are PD and centrifugal gas compressors.

Personal lubricants are liquids or gels used during sexual intercourse and masturbation to reduce friction, enhance pleasure, or reduce pain. They are also used in cases of vaginal dryness. Lubricants can prevent dryness and chafing during penetration. Based on composition, lubricants are classified into water-based, oil-based, and silicone-based lubricants.

Coatings are products used to protect a surface and/or enhance its appearance. Architectural coatings are applied to commercial and residential buildings. They serve to protect a building from elements such as moisture, UV radiation, and microbes. Paints, primers, lacquers, varnishes, and stains are some of the major types of architectural coating products. These products are formulated using various types of resins such as acrylic, alkyds, polyester, and polyurethane. The market may be broadly classified into two major types of coating technologies: solvent-borne and water-borne coatings.

Removal fluids, a type of metal working fluids, are lubricating oils that are used to lower the temperature of metallic work pieces while they are subjected to industrial processes such as machining, grinding, milling, stamping, and forging. Removal metal working fluids are added during the abovementioned and other industrial processes for reducing the heat and friction between the cutting or machining tools and the work piece and prevent burning, smoking, and damage to the tool and the work piece. These fluids help in enhancing the overall quality of the work piece by constantly removing the metal chips from the tool used and from the work piece. Removal fluids are used in various industrial and commercial sectors for applications such as fabrication of metal products, smooth working of machinery, and manufacturing of transportation equipment.

An amine sorbent, prepared by impregnation of polyethyleneimine on silica, was tested for steam stability. The stability of the sorbent was investigated in a fixed bed reactor using multiple steam cycles of 90 vol.% H2O/He at 105 aC and the gas effluent was monitored with a mass spectrometer. CO2 uptake of sorbent was found to decrease with repeated exposure to steam. Characterization of the spent sorbent using N2 physisorption, SEM, and thermogravimetric analysis (TGA), showed that the decrease in CO2 loading can possibly be attributed to a reagglomeration of the amine in the pores of the silica. No support effect was found in this study. The commercial SiO2 used, Cariact G10, was found to be stable under the conditions used. While it was found that subjecting the sorbent to several steam cycles decreased its CO2 uptake, a continuous exposure of the sorbent to steam did not have a significant performance impact. A silanated sorbent, consisting of a mixture of PEI and aminopropyl-triethoxysilane on SiO2 support, was also investigated for steam stability. Similarly to the non-silanated sorbent, the CO2 loading.
