In oil and gas industry gas sweetening process is inevitable when raw natural gas contains acid gasses like H2S and CO2 removal of these acid gases is essential since their presence poses severe corrosion problem to the downstream process lines and equipment. In our project raw natural gas first goes in separator where the water content removed further gone in absorber where amine and that gas react sweet gas goes upward and collected from the top of absorber while the rich amine further process to recover all the amine to reduce operation cost. First of all, we design process flow diagram and select suitable equipment for this process. As we need to calculate different parameter apply material and energy balance on all equipment our target is 200 MMSCFD so we need to fix our mass of feed. After that design all equipment on the basis of our material and energy requirements. In every process we need to apply control loop to run process smoothly, apply control loop on every single equipment. One most important thing is cost of the plant, what is capital cost and what is operation cost? Apply cost estimation.
