Hello all,
Can anybody point me to any references for design of calming/stilling baffles in two phase separators? My particular application is for a horizontal separator, to even out the flow profile in the liquid directly beneath the inlet device, before it flows into some internals.
Mainly...
Hi All,
I have an issue where I'm trying to estimate the pressure drop of a liquid through a multi-hole orifice plate. I know how to do this for a "thin" plate, i.e. thickness/hole diameter <= ~1, but am having trouble finding methods for a thick plate where the aspect ratio of the holes is...
Hi All,
Can anyone point me in the right direction for dealing with trace components in a gas mixture, and whether these need to be taken into account when determining temperature code for equipment?
E.g. I have a gas where the bulk components would warrant T2 (<300 °C). However, there's <100...
Hello Everybody,
I have a case where a valve is needed for regulating the pressure inside a process. The issue is that the pressure setpoint(and flow required to maintain this pressure) varies quite a lot. The valve(s) is installed downstream of the process, and the process itself has inlet...
I have a gas stream as follows:
CO: 22%
H2: 19%
CO2: 56%
N2: 3%
H2S: 500 ppm
The stream is water saturated, 37 C, 4 barg. Flow is approx 380 Nm3/hr.
I want to reduce the sulfur to below 10 ppm. Recovery of the sulfur is not required.
I've spoken to one vendor of iron oxide based adsorbant...
Hi Everyone,
I'm trying to estimate the flammability ranges of a number of gases, all containing various amounts of two flammable gases (CO and H2) and several inerts (H2O, N2, CO2).
From thread (http://www.eng-tips.com/viewthread.cfm?qid=33615) I have dug up the US Bureau of Mines Bulletin...
Hi All,
I'm doing preliminary design on a few pretty small packed columns (max diameter ~300 mm, min diameter ~150 mm, heights no more than 7 m).
Aside from being a bit uneasy about how the 150 mm column will work mechanically/hydraulically, I'm unsure how to account for/treat heat losses. Are...
