My trip to the ADNOC pilot plants was eventful because this was both a discovery trip but also an educational trip. For once, I had a chance to have a first-person experience of all those theories, and classroom lessons. This was an opportunity to see everything in real life. From the wellhead plant to the oil and gas plant, then the gas sweetening plant and finally the gas dehydration unit. The event was meant to introduce the students to the actual plants to see the plant in operations and learn the mechanism of the oil and gas plants.

Our first stop was at the wellhead plant where we learned that the equipment is composed of the production well, the Christmas tree, the production manifolds, the test manifold, the multiphase flow meter as well as the pig launcher. Some of their main operating parameters we were introduced to include the well fluid mixing manifold whole downstream pressures were indicated to be six barg. The flow line pressure that I came to learn is operating at a 4.5 bard and the hydraulic oil pressures whose HP was estimated at 3000 PSI. The plants capacity was also an important gauge that I had a chance to see. The oil flow was 4.0m3/hr. The water flow was 1.0m3/hr. While tree air flow was 5.0Nm3/hr. The wellhead has many parts include the tubing hand, the casing head, and the Christmas tree. During the trip, I had a chance to learn a lot of things, conversion and processes that I never knew existed. Some of the theoretical understandings were also explained to me, and I came to learn why some of the processes that were possible theoretical were not practical.

The second step was at the oil and gas plant where I learn about all the component of the oil and gas plants as well as the functions of each component. I also got a chance to see well fluid being separated into its main constituents including gas oil and water and additional contaminants which are then separated before they are further processed. I saw the separators in action and learned that there is a two-phase separator and three phases separate. The two-phase separator was mainly for the separating the liquid and gas while the three-phase separators were for separating the water, oil, and gas. Each separator had four sections including the primary separation, the secondary separation, and the mist extraction as well as the liquid accumulation section. From this trip, I learned an important lesson, the fact that gravity, fluid immiscibility, the difference in the fluid densities as well as pressures reduction and residence time were important factors that were necessary for the separators to functions properly.

After the oil and gas plant section, we visited the gas sweetening units where the amine gas is sweetened. At this pant, the hydrogen supplied (H2S), the carbon dioxide, the 14 mercaptans and the contaminants that form part of the natural gas stream. I learned that the Hydrogen Sulphide is a very toxic gas that is also corrosive to even the best carbon steel. I also learn that the carbon dioxide is also a very corrosive gas and can corrode equipment and even reduce their heating value. The main reason behind gas sweetening is to move the contaminants such as hydrogen supplied and the carbon dioxide to enable the composing transplant the gas for use. The two important processes in this step included absorption and regenerations.

Our final stop was at the gas dehydration unit (GDU) where we have a chance to see the app 4 in action. The APP4 is whet gas is dehydrated. The GDU plant training skids were the place where we saw the simulation of the glycol gas dehydration unit. This is where people are taught how tri-ethylene glycol dehydrates the wet gas and how the plant used the rich glycol for regeneration and reuse. The gas dehydration plant uses mainly the water and air. I learned that water could be used in place of glycol while air can be used to replace the wet hydrocarbon gas. I was surprised that the flow loop and the control systems were uniquely designed in such a way that the overflow and flow back are prevented. The APP4 gas dehydration plants gas section was composed of the glycol contactor inlet filters, the glycol contactor 704-C-1014 and he lean glycol/ dry gas exchanger. On the other hand, the glycol regeneration section was composed of the reflux condenser, the cold, rich glycol o exchanger, to the flash drum, the glycol charcoal filter as well as the rich glycol filter among others. I learned about many parts of the gas dehydration units as well as the function of each component in the whole unit.


The trip was the most eventful trip among the academic trips I have had. This was the first opportunity that I had a chance to learn a lot of new things, get answers to the questions I have always had and see the plants first hand. The only mistake I made is that failed to ask how to plant is preparing for future changes in technology and their view of the market outlook amidst the current calls for the regulation of carbon gas emission.
