Introduction
Natural gas sweetening is a critical step in the production and refining of hydrocarbon gases. The objective of this process is to remove undesirable compounds such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas. These compounds diminish the quality of the gas and have negative impacts on equipment and the environment due to their corrosive and toxic nature.
Among the various sweetening methods, absorption with liquids, particularly amine solutions, has garnered significant attention. This method is favored for its high efficiency and recyclability. Methyl diethanolamine (MDEA) is an appropriate choice as a tertiary amine for this process. Due to its high capacity for CO2 and H2S absorption, MDEA exhibits unique characteristics. It also has greater thermal and chemical stability, lower operational costs, and fewer side effects

Natural Gas Sweetening
In the natural gas sweetening process, the removal of acidic impurities such as H2S and CO2 is performed using alkanolamines. These compounds are utilized due to their properties, such as low viscosity and non-absorption of hydrocarbons over a wide range of pressures. However, irreversible reactions with organic acids lead to the degradation of amines and the formation of thermally stable salts (HSS), which result in issues such as reduced absorption of acidic gases, equipment corrosion, and foaming in the absorption tower. These salts, along with the reduction of pH in the amine solution, compromise the protective layers of metals and exacerbate corrosion. Annual corrosion costs impose millions of dollars in expenses on the industry, with only a limited portion of these being manageable.
In the sweetening units of the country’s gas refineries, corrosion, particularly in the amine regeneration tower and areas with CO2-rich vapor condensation, is a significant challenge. One of the main causes of this issue is the reduction of the amine inlet temperature to the regeneration tower below safe operational temperatures. In the South Pars gas complex, corrosion is attributed to the high levels of thermally stable salts in the methyldiethanolamine (MDEA) solution and the presence of CO2. Additionally, the high flow rate of amine and elevated amounts of monoethylene glycol (MEG), which is added as a corrosion inhibitor to natural gas, contribute to increased reboiler temperatures and intensified corrosion.
The existing corrosion is attributed to the presence of acidic gases that have not been effectively separated from the amine solution. To investigate and mitigate this issue, unit simulations will be conducted using Aspen Plus software, and operational parameter adjustments will be explored with the aim of increasing amine temperature and reducing acidic compounds at the bottom of the tower.
Description of The Process
Removal of Impurities:
Raw natural gas extracted from the ground contains impurities such as sand, water, and heavy hydrocarbons. Initially, these impurities are separated from the gas. This is typically accomplished through mechanical processes utilizing gravity separators or cyclones.
Removal of Hydrogen Sulfide and Carbon Dioxide:
This stage, known as the main sweetening process, involves the removal of acidic gases such as hydrogen sulfide (H₂S) and carbon dioxide (CO₂). These gases can produce corrosive acids in the presence of water. The primary sweetening processes include the following:
Use of Amines: A common method where amine solutions, such as monoethanolamine (MEA) or diethanolamine (DEA), are employed to absorb acidic gases.
Use of Physical Solvents: Such as sulfolane, which is utilized for the absorption of acidic gases at high pressures.
Water Removal:
Residual water in natural gas must be eliminated to prevent the formation of hydrates and corrosion. This is typically achieved through the use of adsorbents such as silica gel or alumina, or through cryogenic processes.
Removal of Additional Contaminants:
In some cases, it may be necessary to remove other impurities such as mercury or heavier hydrocarbons. This is accomplished using specialized adsorbent beds or distillation units.
Stabilization and Final Preparation:
At this stage, the purified gas is conditioned to meet the desired specifications for transportation and final use. For example, adjustments may be made to pressure and temperature.
Quality Control and Safety:
Finally, the quality of the purified gas is assessed to ensure compliance with required standards. Additionally, all stages of the process must be continuously monitored for safety and efficiency.
Optimization and Simulation of the Unit Using Aspen Plus Software
Design of Column Internals:
The design and simulation of column internals in the natural gas sweetening process at the South Pars Gas Complex aim to remove undesirable compounds such as carbon dioxide and hydrogen sulfide. These columns are designed to maximize the contact area between the gas and liquid phases. By utilizing appropriate trays or packing materials, the separation process is optimized. The selection of materials, optimal design of trays, and operational conditions such as temperature and pressure significantly influence separation efficiency and the reduction of operational costs.
Simulation of the column internals can be performed using process simulation software such as Aspen Plus and HYSYS. These software tools allow engineers to modify various parameters, including temperature, pressure, and feed composition, and observe their effects on column performance. The simulation results help identify the strengths and weaknesses of the design and enable process optimization. After conducting simulations and analyzing the results, necessary modifications are implemented to enhance column performance, followed by operational testing to verify efficiency and compliance with the initial design.
Based on the simulation results, the figure below illustrates the bed temperature profile, while the table below displays the concentrations of carbon dioxide and hydrogen sulfide in the upstream and downstream flows of the regeneration column under operational conditions.
Sensitivity Analysis and Optimization of Pressure and Flow Rate in The Regeneration Column
The sensitivity analysis of pressure and flow rate in the regeneration columns at the South Pars complex is conducted to assess the impact of variations in these parameters on system performance. By developing mathematical models and performing precise simulations, critical points can be identified where small changes in pressure and flow rate can significantly affect the purity and output flow rate. This analysis not only aids in identifying key parameters but also provides insights into predicting system behavior under varying conditions.
Following the sensitivity analysis, the optimization phase for pressure and flow rate commences. In this phase, simulation techniques and optimization algorithms are employed to determine the optimal values for these parameters. This optimization can lead to reduced operational costs and increased production efficiency. The simulations conducted in this context provide a detailed representation of the system’s performance under different conditions, assisting decision-makers in formulating effective strategies to enhance the efficiency of the regeneration columns.

Calibrating simulations with operational data is one of the critical stages in validating simulation models. In this phase, the results of the main simulation are compared with actual data collected from the complex to assess the accuracy and reliability of the model. If the simulation results align with the real data, confidence in the model’s validity can be established, allowing it to be used for predicting system behavior under various conditions. This calibration process in Aspen Plus assists managers and engineers in making informed decisions regarding the optimization and management of processes.
Heat Exchanger Design (Version 12)
In simulating heat exchangers using EDR software, the HEX heat exchangers were initially substituted for the previous heat exchangers. The selected heating fluids include LP Steam for the feed stream and MP Steam for the return stream.
The mass flow rates of these fluids were calculated based on the heat transfer equation. For LP Steam, the flow rate was determined to be 4900.3 kg/hr, while for MP Steam, it was established at 4952.06 kg/hr. Following the simulation of the exchangers in Aspen Plus Version 12.1, their specifications were designed using Aspen EDR Version 14.
The design of the exchangers involves determining dimensions, heat transfer area, and tube types to achieve optimal heat transfer performance. This design is conducted based on the flow rates and inlet and outlet temperatures of the fluids to enhance the overall system efficiency.
