    Dehydration Column with gas feed not saturated with water

    Hi I am calculating the required height of a TEG column to dry gas. The incoing gas is NOT water saturated (due to pre heating). I see some methods (including Shell DEPs) assume saturated inlet feed. I am now using the methods in the Campbells gas course books. Does anyone know if this method...

    HPU Accumulator charge time

    I know very little about hydraulic systems but am looking at one for closure of ESD valves. We have pumps (not normally running) and accumulators which will provide system volume to move valves. I'm wondering about the criticality of the charge time of these accumulators. The duty pump kicks...

    Glycol reboiler too cold

    Glycol flow is quite steady as pumped by PD pumps and is as per design. The temperature is failry steady and any small variation does not seem to align with any variation in the reboiler temperature.

    Glycol reboiler too cold

    I'm a process engineer working on a site with glycol dehydration. The reboiler in our glycol regeneration unit is supposed to operate at 193degC, but we can't seem to raise the temperature above 185 degC or so. The glycol is heated in a kettle by condensing steam within tubes. Steam supply is...

    Oil treater (electrostatic) - impact of gas

    I work on a facility where part of the separation train is a degassing separator, which physically sits above a liquid full electrostatic oil treater (separating water from the oil). The vessel (treater) obviously runs liquid full. My question is what is the impact of gas getting into the...

    Hydrocarbon and water dew Point in Hysys

    Hello I am trying to understand some Hysys results from my Hysys Gas Properties extension which calculates Hydrocarbon and water dew point. My gas is in the dense phase according to the phase envelope produced by Hysys(operating pressure greater than circondenbar) and for this I would not...

    Estimating Air Cooler Capacity

    I need some advice on estimating the capacity of air coolers (in particular, depropaniser and debutaniser condensers). It is well known that the fin fans have a higher capacity (ie maximum duty in KW) at lower ambient temperatures. I need to estimate the actual capacity of the coolers through...

    Controlling contact angle

    Nick A surfactant coating will indeed change the contact angle by making the surface more hydrophillic (or phobic). Titanium dioxide coatings are an option. I would imagine that work has been done on this in the membrane industry (prevention of fouling) and even in commercial glass production...

    Storage Tank Level control

    I'm a young process engineer - I need to specify a low pressure (<100 mbarg) fixed roof (cone) storage tank. Tank is blanketed - blanketing used for pressure control. Capacity (from low to High level) is set by a process fluid residence time. Tank likely to be mounted on concrete plinth to...
