Hi all!
This is a simple question:
A flush type cleanout connection with the next dimensions:
Width: 24"
Height: 36"
can be allowed by API 650? That set of dimensions are not in the tables of the standard.
However, standard 650 in paragraph 3.7.7.1 states that:
'....When a size...
HI ALL!
We are about to design a flaring gas recycling system for a LPG plant. It will include a low suction pressure compressor attached to the flare header downstream KOD and upstream the flare. Also, a water seal liquid is going to be installed before flare in order to avoid backflow at very...
Hi all!
I'm in a big hurry trying to verify if a vessel could be adequated for a new service. The problem is as follows:
1.- The vessel is 36 in OD 10 feet high, pipe A-106 Gr. B.
2.-Bottom ellipsoidal 2:1 cap A-516 Gr. 70.
3.- Top Flange B.16 600#.
and should be used in the following...
Hi All!
I have designed a system for deareating 170 m3/h of river water from 13 to 0.7 ppm of oxygen. This system consists of a deoxygenation tower (Operating pressure 70 mbara) and a liquid ring pump. I've found that it is necessary to extract abt 6 Kg/h of gas/vapor from the water stream to...
Hi all!
I'm trying to dimension a vacuum deoxygen column to pretreat 170 m3/h of river water to be injected in an oilfield. The oxygen and other dissolved gases are removed from water by means of vacuum generated with a liquid ring pump. The process is carried out at 25ºC and 35 mmHg (abs)...
Hi All!
Recently I found a conceptual description of a Wastewater treatment plant where "Overlap Backup Design" is mentioned as a philosophy of design. From that philosophy it is proposed to install two parallel separation trains wich includes: coalescer, flotation unit and filter. Each train...
Hi All!
We have a gas with the next approximate mole composition:
CO2 90.0%
C1 9.0%
CN 0.9%
H2S 0.1%
Pressure 80 Kg/cm2g
Temperature at gas pipeline inlet 50 ºC.
It is desired to inject this gas in an oilfield. Do you have any idea if a moisture content of 9 lb/MMscfm is convenient...
Hi All!
Any one know what is a typical flowrate for start-up air in a reciprocant compressor for natural gas?
and what this air is used for?
Thanks in advance.

Hi All!
I'm just trying to verify the actual capacity of a indirect fired heater API 12K type. API 12K only gives a general guidance based on "standard capacities" from 100M to 1.5 MM btu/h
After following a laboriuos method to find heat transfer coefficients at the fire tube side, and...
