1. What is the goal of a SPF or oilfield facility? The main goal of a SPF or an oilfield facility is to separate the well stream fluids into oil, gas and water, which are single-phase components to sell them and/or further process them. 2. Is flaring and venting of produced gas largely used today? What happens with the gas that cannot be transported? Nowadays flaring and venting of produced gas is not largely used because some governments assembled some protocols not allowing companies to flare to avoid polluting the environment however it was used in the past. Nonetheless, companies now use a process of compressing the gas that cannot be transported is now used so it can be reinserted into the reservoir. 3. In which ways is an oilfield…show more content…
The main thing about the components is that a glycol gas dehydration system represents a tower that has or consists of two inlets and two outlets with a contact area in the middle of the tower. So, the glycol is injected into an inlet to absorb water and gets out as rich glycol from the outlet exiting the bottom of the tower and going to a separator to be used to remove condensate hydrocarbon. In the mean while, the inserted wet gas that had the water absorbed gets out from the other outlet as a dry gas since that the water was absorbed by the glycol and then it continues to sales. Moreover, the rich glycol goes to heating up to 390 to 400°F so the water boils off. This vapor is usually disposed or used in the separation of small hydrocarbon that is found in the vapor after its cooled and condensate. Finally, an exchanger is used to cool the hot, and lean glycol by going through it with the cool, rich glycol coming from the contact…show more content…
• Intercooling and after cooling of compressors outlet gas stream. • In a glycol contacting or injection system, the heat interchanges of lean glycol. 21. What is "LET"? Under what condition may water removal not be absolutely necessary? Under what condition may gas exhibit hydrocarbon condensation in the pipeline? If we have condensates, what three alternative procedures can be adopted? • LET is lowest expected temperature. • Water removal is not absolutely necessary if the LET higher than the hydrate point of gas. • Gas may exhibit hydrocarbon condensation in the pipeline if the cricondentherm of the gas is higher than the LET, and the pipeline pressure fall into retrograde zone. • If we have condensates, there are three options: o Two-phase pipeline flow and no condensate removal and. o Condensate removal to produce a hydrocarbon dew point less than the LET. o Dense phase transportation and not removing condensate. 22. What is a transportable gas? What is a salable gas? What three situations motivate maximization of condensate recover? • A transportable gas stream refers to the marginal processing in the field and the transportation in pipeline to a final processing
