How much is it important to have isolation valves on the main lines feeding the bridle on which level switches and LG are installed which have their own isolation valves.
Plant operation reasons out that since the liquid in the bridle remain stagnent therefore becterial growth causes corrosion...
Can someone tell me, the gas flow volume through an orifice, calculated from the common formula given by different vendors, is at upstream pressure or downstream pressure?
One of the recommendations in a safety audit suggests to identify crude oil/ condensate storage tank which are 'self blanketed'. The recommendation further explains the criterion for self-blanketing as being “a vapor evaporation rate, which is greater than 1.5 times the maximum pumping draw...
Gas blanketing is generally used in tanks to prevent ingress of Oxygen. API 2000 criterion is normally used to calculate the blanketing gas requirement for petroleum products tanks.
A term of “self blanketing” is referred that propagate that any petroleum product(s) whose evaporation rate is...
I have to develop specifications for procuring a cetrifugal compressor that should raise the Natural gas pressure from 25 psig to 400 psig.
A sample technical spec sheets would be of great help. Any other material or technical advice shall also be appreciated. The Natural Gas Sp. Gr. is 0.65
Produced natural gas at a pressure of 2000 psig needs to be injected in a gas well to maintain pressure. Two Ariel compressors are in Series to raise the produced natural gas pressure from 300 psig to 2200 psig.
Is it a normal practice to install a filter before the wing valve of the well to...
I need assitance in designing a system that should be capable of providing air to a fire Hooter. The big hooter, having a range of 6 Killometers, has been procured, it requires 9.6 cu. ft per second air at 125 psig to blow. Since, No air is available therefore, I recommended three standard...
Are you or do you know anyone using Hysys 3.1? What are the features which are different than the 2.4.1 version? Is it a full version containing ACX, STX, Amine..etc.?
From a new well the expected oil production is around 1200 BOPD and water, initially 50 BWPD and with the time increases to about 5000 BWPD. The Crude oil is paraffinic and has the following properties.
Pour point 95 oF
Well Head Temp. 95 oF
Crude API 35
Sp. Gr. 0.8
For the...
Wellhead panels operate in many cases on fuel gas. In several cases the separation of condensate or oil from the fuel gas supply has proved inadequate resulting in damaging the equipment or malfunction.
It is desired to improve the fuel gas by knocking down the heavy hydrocarbons and moisture...
Gas engine (driver to a compressor) is to be converted from high BTU gas to low BTU gas. Based on available data I have calculated the amount of gas required. Am I on right track? Appreciate your input and comments.
Available Data:
Rated bhp @ 900 rpm = 748 = 558 kWb
Gas Heat Heating...
Wellhead Control panels at wells operate in many cases on fuel/instrument gas drawn from test/production separator.
It has been observed that the fuel/instrument gas is not conditioned properly to the desired quality by simple filter separators available at remote sites. This has resulted in...
In a Oil and Gas treatment facility the tanks drains and vessels blow downs are connected to a single skimming tank. The skimming tank is open to atmosphere. A number of vessels operate at 1100 psig.
Considering the safety aspect a two (HP and an LP) header policy has been adopted. Th HP header...
