Gas sweetening is one of the important purification processes which is employed to remove acidic contaminants from natural gases prior to meet transport requirements and sale gas specifications. In this work, simulation and parametric studies of the natural gas processing plant of Missan Oil Company/Buzurgan Oil Field of Natural Gas Processing Plant (in Iraq) were considered. After simulation and validation of this plant, the effect of feed temperature and flow rate and solvent concentration were considered. Results show with increasing the feed temperature and flow rate, the amount of H2S and CO2 in the sweet gas stream increases. Then, in the next step, the effect of mixture solvents was studied. Sulfolane–MDEA and MDEA–MEA were selected as a physical–chemical mixture solvent and chemical mixture solvent, respectively. The simulation results show that the solvent price and reboiler duty and cooling duty can be reduced by using a mixture solvent. However, the amount of H2S and CO2 in the sweet gas can be affected by these solvents. The system by a chemical mixture solvent can better performance than other solvents.

“…When the tower's temperature decreases, the lower flow of the solvent is needed to reach the standard characteristic of refined gas. Also, Zahid et al [16] studied the simulation of this plant using Di Glycol Amine (DGA). By developing a steady-state model, they predicted the CO 2 capture mechanism from the natural gas using DGA solvent.…”

The developing issue of the present world is a worldwide temperature alteration, which is caused by ozone-harming substance impact. Carbon dioxide has the real commitment towards a worldwide temperature alteration as it is discovered copiously in climate given anthropogenic carbon dioxide outflows and advancement of vent gasses. Businesses are additionally debilitating corrosive gasses (CO2 and H2S) in the earth, which prompts the perilous conditions. To control such conditions lessening of these hurtful gasses is valuable for which ingestion of corrosive gasses is for the most part favoured. Amine gas treating is an appropriate system to complete this work as it expels CO2 and H2S at the same time from petroleum gas streams and also modern gas streams and decontaminate them for local use and solid condition individually. For this purpose, study the best solvent selection for CO2 capture in chemical absorption. In chemical absorption amines solvents are used. Amine is one of the applicant solvents which is utilized for carbon dioxide recuperation from the pipe gas by chemical absorption /desorption process. This research focus on the effect of various amine absorbents, their concentrations, the absorber and stripper section statures and the working conditions on the carbon dioxide recuperation plant for post-combustion carbon dioxide evacuation. For every amine dissolvable, the ideal stages for the absorber and stripper segments, and the ideal absorbent concentration, the ones that give the base conditions for carbon dioxide evacuation is determined by Aspen HYSYS simulation. The results obtained showed that carbon dioxide recuperation with 50 wt. % DGA requires the best ideal conditions for removal of CO2 with the following design and working conditions are 10-organize absorber column and 10-arrange stripper segment, 20.89 m 3 /hr circulation rate of solvent and 2545 kW of reboiler obligation and 100 o C as the regenerator-delta temperature and absorbed 93.6% CO2.

“…In addition, the partial pressure of CO 2 will decrease with the decrease in the absorber pressure, hence, the reaction rate will be affected and the removal efficiency of CO 2 will decrease. In addition, On the other hand, as the reaction rate decrease, the heat liberated from the reaction of CO 2 with the DGA/PZ solvent [21] will decrease causing the top temperature of the tower to decrease. This reduction in temperature is expected to compensate the effect of reducing pressure on solvent volatility.…”

The effect of adding Piperazine to di-glycol amine (DGA) to reduce the CO2 content in natural gas from 10% to 1% by mole was studied. Aspen HYSYS was used to simulate the process. Different concentrations of DGA (45, 50 and 55%) and Piperazine (3, 5, 7, 9 and 11%) were investigated. The effect of circulation rates variation from 1000 kgmol/hr. to 5000 kgmol/hr. were examined. Moreover, temperature ranges from 38 oC to 80 oC and pressure ranges from 45 kg/cm2 to 80 kg/cm2 were studied for 55% DGA without and with the addition of Piperazine. It was found that adding 9% Piperazine to 55% DGA achieved the best absorption efficiency. By using Piperazine, the circulation rate required to reach the 1% CO2 level was reduced to 3250 kgmol/hr. The amount of captured CO2 was found to increase with the decrease in the lean gas temperature and the increase in absorber pressure.
