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…
The role of rubber process oil in the production of car tires
First lets know some information’s about RPO , one of the major factors in producing tires Rubber oil has many applications and is produced in paraffinic and aromatic types. Rubber oil is used as the main raw material in the rubber manufacturing process and has filling and modulating tensile properties of tires. Rubber : 1. Rubber and plastics industries 2. Industries producing auto rubber parts 3. Conveyor belts and sealing tapes 4. Ink production industry Printing of panorama global trade sdn bhd has the ability to distribute this oil with the following three grades. Advantages of rubber process oil : 1. High flash point and low volatility 2. High dispersion speed in mixing with other materials 3. Suitable aniline point of this set according to the production method and type of part (depending on customer needs) can be all grades of rubber oil The following is an example of an analysis…
