hi 247338, I know that "Petroleum Experts" organizes some training on the subject try to take a lokk at theire site: http://www.petex.com/courses/?ssi=11 good luck! kader

Thanks dcastro for the advice! anyway the bosses chose to implemente the line looping solution

For those interested I found on the net also this: Salinity is the saltiness or dissolved salt content of a body of water. 35 g dissolved salt / kg sea water = 35 ppt = 35 o/oo = 3.5% = 35,000 ppm Salinity in Water drinking water 100 ppm restriction on drinking water 500 ppm limit drinking...

Great job! Thanks bimr

hello guys as I am not an environmental engineer but a mech one, I am preparing a small report about the use of water in the field (petroleum)as you know all the oil companies are decreasing their use of freshwater for an environmental reason,I am facing a small issue regarding when can we call...

well the low flow condition is mainly caused by the increase of the gas volume in the lines (mainly because the GOR is getting higher) this causes an increase of the pressure in the lines that acts as back pressure so the flow line starts to have higher pressure or near the well head pressure...

here bellow a small draft about the problem I am facing to clarify the issue! thanks and sorry for disturbing you guys!http://files.engineering.com/getfile.aspx?folder=583711e0-db1f-4653-b9f0-3ee8b2096a9c&file=flow_assurance_issue.doc

thanks BigInch for your reply actually the 3 lines I spoke about above are already coming from clusters so the well issue shouldn't be a problem as in each line a set of well is already producing through, for us the main issue is that the gas oil ratio of some wells starts increasing and we are...

Hi every one, I was looking for any advice that could help me sorting out a solution for a practical problem that we have in the field. The main issue is that we have 3 lines coming from different wells (oil) that are connected in a gathering line (trunk line)which constitute a bottleneck, to...

Hi prostreet, I don't think that carbon steel suffers any corrosion problem with methanol! in a previous post I've attached a file with a list of material/environment compatibilities you can take a look at it: http://www.eng-tips.com/viewthread.cfm?qid=217762 the aluminum alloys on the other...

Dave has already answered your question, I would add to your own sentence "I guess it's letting steam down.." "the right amount" I mean if you're producing superheated steam it's not to lower it down the saturation temperature! the de-super heater is mainly installed to control the...

here is a list of some materials and their resistance to different corrosive media (curtsy of engineering toolbox)I've just added some colors! :) hope it'll help kader http://files.engineering.com/getfile.aspx?folder=d203885f-aac7-43b9-9d43-5de2d4c2f5e4&file=corrosion_of_metals.docx

JSZA, The material you are speaking about X5 Cr Ni 18 10 is what is commonly known as AISI 304! it is an austenitic stainless steel and it is sensitive to corrosion by Chloride where it suffers from pitting and also what we call stress corrosion cracking (SCC) so care should be taken when...

I agree there are more then one value even the one that I gave you previously seems false! From "chemical Properties Handbook" I had 0.86 cP at 20°C I've compiled their formulations in an excel page you'll find the variation with temperature but it's for the pure HNO3 not a solution, sorry...

safetystudies, I found for nitric acid: viscosity at 68 °F (20 °C) : 2.6 cP Sg = 1.37 take a look here: http://www.gates.com/brochure.cfm?brochure=2625&location_id=3046 hope it'll help. good luck! kader

Hello ThijsM, I'm not an expert in the matter but as the process is based on combustion and as in all the petrochemical plants we carry continuous monitoring of the flare emissions, why don't you think to make a steam flow control regulated by the limit values of the combustion product (NOx and...

Hi moshe, as you are speaking about Merox, you have an H2S or sulfur issue so just "google" for "Oxygen analyser" and try to find the specs that suit your stream! as an example: http://www.landinst.com/combustion/products/combustion/oxygen_analysers/oxygen_analysers.htm it's not the only one...

Hi again guys! bsfc9 why don't you think about a much more simple solution? I mean why don't you think to throttle the discharge line by installing a valve (a pressure control valve I would say). Knowing the deltaP=10psi (which will be the pressure drop through the valve) that you are wondering...

hell bsfc9, actually I don't get the point with your post! specially for the sentence "I will be installing a spring loaded relief valve in the discharge line to regulate the pressure"!!! keep in mind that we install relief valves for emergency cases as they are called elsewhere PSV for...

Thanks Zoobie so you saved us! I told you we were in need of a "chemical" in this side
