Abstract:
Gas Sweetening Unit to Sweet 200 MMSCFD of Natural Gas
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.
