25362, The calculation method is based on Spirax Sarco website. http://www.spiraxsarco.com/resources/steam-engineering-tutorials/steam-engineering-principles-and-heat-transfer/superheated-steam.asp Example 2.3.5 Superheat created by a control valve. Steam property is based on ASME STEAM TABLE.

We do the hand calculation again and find the super heat is quite small, less than 4 C over the saturated temperature. This small degree of superheat can be removed readily in the first part of the heating surface. Thus, this is not an concern any more. Drexl, Still thank you a lot for the...

Deal all, one query regarding to steam desuperheater. 1. system description 3rd party High pressure steam 40 barg into Plant Battery limit, reduce the pressure to 17 barg with PSV installed downstream, then feed to one dedicate heat exchanger through another control valve which...

thank for the all valuable response! nli

When pump sizing, there could be many different type of flow meters, vortex, orifice, coriolis, magnetic etc. Question is how process system engineer estimate the flow meter reasonalbe pressure drop ? Thanks for the help in advance. nli

A air tank (vertical) located in the discharge line of the existing 2 rotary screw air compressors: (1) to remove the possible contaminant. (2) provide buffer time and smooth the compressor operation. we shall install a new compressor with same capacity as existing cmprs. Idea is try to share...

Polyroly, I assume potable water used for eye-wash and emergency shower if no other users in plant.In this case, Refer to ANSI Z358.1 which indicated the required flow rate for shower/eyewash. you may want to reasonably assume some showers/eyewash operate at a time,thus you get the flow rate...

thanks!very helpful! We pump the heavy naphtha out of plant to downstream tankage.It is motor-driven pump.Do check the pump NPSHA per naphtha stripper column Low-low level,sizing the pump suction line per rated flow. Protect pump with the minimum kick back line to the source column with FIC to...

Hello, How to sizing control valve on centrifugal pump minimum kickback line? [not using restriction orifice]. Say,Pumpflow on main discharge line (rated/normal/turndown) is 400/360/180 m3/hr, minimum stable flow is 100 m3/hr per pump vendor. What is max/normal/min flow for this kickback control...
