A tray consists of the following components, as shown in figure below: Overflow, or outlet weir Downcomer Tray deck There are two types of tray decks: perforated trays and bubble cap trays. In […]

Oil Refinery Processes

  Process Objective: To distill and separate valuable distillates (naphtha, kerosene,diesel) and atmospheric gas oil (AGO) from the crude feedstock. Primary Process Technique: Complex distillation Process steps: –Preheat the crude oil feed utilizing recovered heat from the product streams –Desalt and dehydrate the crude using electrostatic enhanced liquid/liquid separation (Desalter) –Heat the crude to the […]
