  • Total Chlorine by Modified ASTM D7536 with Accu-flow

    X-ray Fluorescence (XRF) spectrometry, while widely used for total sulfur testing, has traditionally been an ineffective tool for the direct measurement of total chlorides in crude oil due to the settling effects of inorganic chloride salts during the measurement process. This settling leads to poor precision and an industry preference for other measurement or sample extraction techniques.

  • Approaches to simulating distillation and absorption

    Distillation of spirits has been practiced since the time of the ancient Greeks who ascribed sacred powers to the liquids that resulted from refining wine using stills such as the one shown in Figure 1. Dionysian cults incorporated these early spirits into religious rituals. Distillation and other phase separation processes have come a long way since then, and so have the ways they’ve been analyzed and computed. Figure 2 shows the progression of models and computational ...

  • A single integrated vacuum system

    Failure to design the vacuum unit as an integrated system will invariably result in unsatisfactory yield and poor product quality (high vanadium, nickel, microcarbon, or asphaltenes), and ultimately, an unscheduled shutdown. To avoid these revamp problems the charge pump, fired heater, transfer line, column internals and ejector system must all be evaluated and designed as a unified whole so that critical variables – heater outlet temperature, coil steam injection rate, ...

Channel baffles are a very straight-forward design modification that improve vapor/liquid contact, increasing tray efficiency in low ...

  • Important tray design features that improve column operating reliability

    How often does Maintenance personnel open a column during a shutdown and find tray panels fallen without any obvious damage? How about tray valves stuck in the bottoms pump suction? While the initial reaction may be to blame faulty installation where the hardware was not properly tightened, the answer often lies in the design of the tray. Reliable column designs need to produce on-spec products at the design capacity, while operating with energy usage at a minimum. For this to ...
