Adsorption of carbon dioxide in monoethanolamine solvent using surface method
Carbon dioxide gas is one of the main environmental pollutants that can cause irreparable damage by climate change; Therefore, solving this problem requires serious attention. At present, chemical adsorption of CO2 with aqueous solutions of alkanoamines is the most common commercial separation method with high efficiency in the industry. Among the various methods of removing carbon dioxide from flue gases, the monoethanolamine (MEA) aqueous solvent adsorption process has been the most important option in industrial applications in recent years. In this research, MEA solvent has been used to evaluate the amount of CO2 absorption. The experimental range of the studied components includes temperature of 20-60 degrees Celsius, pressure of 3.5-9.5 times and solvent concentration of 2.5-8.5% by weight. Loading and CO2 uptake percentages in MEA aqueous solution were obtained in the range of 0.70-2.615 and 17.81-48.65%, respectively. Analysis of the results A quadratic polynomial pattern with response level method (RSM)…
Recycled Base Oil
The definition of second oil recycling and correction has changed over the years. In the past, recycling of working oils could mean many things, in the beginning oils were used as filtration as fuel. In this way, none of the pollutants in your area are removed and it is not suitable for car use. This oil is generally used for fuel. The correction process of the second year causes all impurities, location and insolubility and return of oil as base oil to be fresh. This second refining base oil is equal to or better than some virgin base oils (produced from crude oil) and is suitable for use in cars. The second oil refining process is shorter than crude oil refining and uses less energy After draining, the oil is passed through a filter in two stages and the filtration operation is performed to separate the coarse particles and then…
Rubber process oil and environment
Rubber process oil was prepared from naphthenic base crude feed using extraction or adsorption methods to remove poly nuclear aromatic hydrocarbons (PAHs). Are there any eco-friendly tires? Yes, of course, and the advances in technology will surprise you. Many motorcycle companies have also decided to build environmentally friendly vehicles that are environmentally friendly and durable. In fact, these vehicles are so named because of their reduced carbon dioxide emissions. Replacing tires is usually a financial concern for most people. We all know that tires have a function or function that you do not seem to care about. So if you are looking for the best tires on the market, you may be thinking to yourself. Make sure that this vulnerable part of the car is not worth the high cost. Tires not only ensure a smooth and steady movement on the road surface, but also are considered as the most…
Organic chemistry and labsaco
In ancient world substances of plant or animal origin were called organic matter, but today organic matter can be synthesized through industrial and laboratory methods and with the help of minerals. In Asian cultures, the meaning of the word “organic” is related to living organs and any creature that has multiple instruments, components, or organs. meanwhile humans are constantly exploring their surroundings, it can be said that carbon is an integral part of nature, and to identify and study nature, we must first examine the most detailed element of nature, which is carbon. Organic chemistry is one of the special courses in the field of carbohydrate research. Organic Chemistry 1 is one of the special courses that first examines hydrocarbons and their related chain and ring compounds and by processing the chemical reactions of these molecules opens the way for more extensive research in the field of these valuable compounds.…
