Overview of Air Cooled Heat Exchangers What Is Piping Air Cooled Heat Exchanger -Fan Speed Control - Chemical Oct 30, 2008 · Air Cooled Heat Exchanger -Fan Speed Control npf (Chemical) (OP) 19 Sep 08 20:05. All: Limitedone (Petroleum) If this is total condensation service, what you can do is to modify this scheme with hot vapor bypass or to try how ACHE will work as flooded condenser. Hot vapor bypass is simple and straightforward, and it works in 100% of cases.
AirBTU provides ASME Air cooled heat exchangers for pipeline gas coolers and pipeline oil coolers. Air Coolers for cooling hot oil, gas and produced water in well-head and pipeline applications. Thermofin Air Coolers Unique extruded fin heat transfer surface is the industry standard in efficiency and performance.since condensation will create vacuum, pressure will significantly drop. if the pressure dicreases too much, this means you condensate too much, th11. Confirm whether there are any louvers on the top. 2. Refer yourself to API 661 C.3.1 Airflow and air temperature control systems, and Figure C.I guess the pressure control is cascade with level controller of the dowstream receiver. Frankly speaking I do not know the reason, but I think witthere is absolutely no reason to have speed control on a propane condensor, UNLESS its a reflux condensor.This is a poor control scheme - controlling the tower (overhead) pressure by manipulating fan speed. It is proven to be very inefficient, mostly beI've only speed controlled a propane condenser to reduce nighttime fan tip noise. I set the pressure at 1200 kPa and let the speed vary to try andA couple of questions Is it normal and customary to use a finned-tube air cooler in condensing service ??? Or is this a case where equipment waWe ALWAYS use finned tube condensers in air cooled propane condensing service. Vacuum is not necessary - it's impossible to get a vacuum in propanIt is not clear why speed control of the air cooler fans is required in this service. Once money is invested in the air cooler surface area, does i
