Base Oil SN 150
Generally, base oil is an oil that is considered as a base for lubricant and is more polar in nature than paraffin oils. As a result, it has good cooling properties and excellent properties at low temperatures. This oil also has better solubility and ability to form stable emulsions and in terms of viscosity includes different groups. One of the base oils is the application of SN150 base oil. Base oil is used for engine oils, industrial oils, lubricating greases, etc. Oil cutting resulting from the refining of crude oil resulting from the de-waxing operation. High viscosity index (VI) and low amount of sulfur and unsaturated hydrocarbons, It has made it a suitable material for the production of multi-grade oils and some industrial oils.

Formulated amines
In the formulated amines, methyl diethanolamine is added to the activator, and as a result, by strengthening this amine and maintaining its advantages, its main weakness in the low absorption of carbon dioxide is eliminated. This is done by increasing the rate of reaction of the solvent with carbon dioxide. The main reason for their widespread use in the global gas industry is the reduction in equipment size and energy savings in these processes compared to other amine processes. Other advantages of using these solvents are: reduction of corrosion and reduction of circulating solvent flow Each of the formulated amines is produced exclusively by a specific company and is under the proprietary license of that company. The following table lists the types of formulated amines and their licensed companies. Activated methyl diethanolamine One of the most well-known and widely used formulated solvents is activated methylmethanolamine (activated MDEA), licensed by BASF…
What are the other types of amine
In the following table, the first, second and third types of amines are compared in terms of commonly used concentrations and adsorption capacity of acid gases: Amine name Molecular Weight Normal concentration (weight percentage) Acid adsorption capacity (IB MOL / T) Monoethanolamine 61 15-20 2.53 Diethanolamine 105 25-35 2.52 Methyl diethanolamine 119 35-50 4.16 Also, the first and second type amines react directly and rapidly with hydrogen sulfide and carbon dioxide. The third type of amine reacts directly and rapidly with hydrogen sulfide, but reacts slowly with carbon dioxide in two steps. Therefore, by limiting the contact time of amines and acid gases, hydrogen sulfide can be selectively separated. Properties of monoethanolamine Advantages Disadvantages High reactivity Wasted up due to evaporation low price High energy required for regeneration Possibility of separation of carbonyl sulfide and carbon disulfide Impossibility of selective separation of hydrogen sulfide in the presence of carbon dioxide…
Production method of monoethanolamine
Monoethanolamine is obtained from the reaction between ammonia and ethylene oxide. This reaction produces diethanolamine and triethanolamine in addition to monoethanolamine. The production ratio of different products can be adjusted by changing the stoichiometry of the reaction. This reaction is thermal and should prevent the temperature from rising and reaching the flash point. Ethylene oxide reacts slowly with ammonia, adding water to speed up the reaction. In processes without water, a fixed bed catalytic reactor with ion exchange resins or zeolite and clay is used. The whole process takes place in the liquid phase and the pressure in the reactor is high enough to prevent ethylene oxide and ammonia from evaporating at the reaction temperature. Monoethanolamine is recommended as a substance for making alkanolamides because of its reaction with fatty acid or coconut oil. As a result of its properties, this product is used in various industrial sectors such as…
