    PLEM DESIGN

    Being an experience Process Engineer I have been asked to Design a PLEM. First I got lost what is PLEM then found out What is PLEM. The datasheet given to me is entirly different than a Manifold data sheet. Appreciate experts help. I have been told it is for inhouse design and not for submission...

    Pump Selection for Production Separator Liquid transfer

    I have been asked to look for a suitable pump that can pump liquid from two phase separator to another platform. The production separator will be operating at 40 PSIG whereas the pump discharge reuirement is 140 psig. The amount of liquid is around 30,000 blpd (oil+water). Neither electricity...

    Type of Suitable Compressor

    Gentlemen: As mentioned in the beginning of my thread that around 30 to 50 mmscfd gas from the separator (operating at 20-30 psig) needs to be pressurized to about 100 psig for transportaion to other platform. I need to know how Coleman equation can be used to predict the amount of carrier gas...

    Type of Suitable Compressor

    pmover: I have not explored the restaging of existing compressor but my guess is there is no room for using the existing compressor at low pressure. It is based on assumption that if there had been the production people have long ago done it to increase the production from low pressure wells...

    Type of Suitable Compressor

    Gentlemen, The gas is wet, water saturated and a heavy gas, right out from Production Separator. The Separator is to be operated at 75 psig. The produced gas is transmitted to another Gas compression Platform. The Gas Mol weight is around 20.4, amount of the gas is in between 30 and 50 mmscfd...

    Engineering Deliverable for Pre and post drill

    By default I have become a project engineer for revisit of wells. The process engineers are doing blowdown calcs along with P&ID redline to connect the platform blowdown with the rig flare in addition to preparing the Long Leed Item list. Instruments is checking the available slots in pannels...

    Control Valve versus Variable Speed Pump

    Gentlemen I have to maintain Normal level in a production separator. I am using a variable speed pump to draw the liquid and pump to a high pressure (from 30 barg to 100 barg). Normally, the liquid flow will remain constant with the exception when pigging operation is in progress. To control the...

    Minor and Major barrel length for 20" pipeline receiver

    Thanks gentlemen for the discussion and ideas. Sharing knowledge makes the life easy. Thanks once again

    Minor and Major barrel length for 20" pipeline receiver

    Gentlemen The minimum length for a 6-inch launcher barrel should be 6 feet. For each pipe size above 6-inch add 1 foot (i.e., 8-inch should be 7 feet, 20-inch should be 12 feet, etc.) I found the above statement while going through a search for a 20" Pig Launcher minor and major barrel length...

    3-phase Separator and Slug Catcher

    I am working on the P&IDs, might take some time to finish

    3-phase Separator and Slug Catcher

    SNORGY Since there is no response from experts on the forum should I consider that my proposed option has a merit other than decasto which requires a paradigm?

    3-phase Separator and Slug Catcher

    SNORGY I am going to ensure that the KOD pump is big enough to meet the requirement, Thanks, any other suggestion? dcasto Your suggestion is valid and a way can be found to implement it but I want a paradigm. I believe that due to number of risers and may be vibration it may not be a good...

    3-phase Separator and Slug Catcher

    Thanks gentlemen for your interest. SNORGY[/]The crash dump I am thinking to take it to the Flare Knock Out Drum unless there is good reason Not to use it. [b]decatocan you elaborat a little more keeping in mind that it is offshore platform, space and enornment are challenging.

    3-phase Separator and Slug Catcher

    dcasto, u r right about the emulsion formation if the valve is provided upstream. ur second suggestion has a merit provided option-1 is considered. But there is a space limitation and two piece of equipment are difficult to accommodate. I am looking for an option that kills the two birds in one...

    3-phase Separator and Slug Catcher

    Considering the limited space available on an offshore platform the task is to design a 3-phase separator that can accomodate possible slug of well fluid. Options available are: (unless someone has better idea) (i) Have a slug catcher followed by a separator, but this option requires a great...

    Simulation dummy models

    I have done simulation on Hysim in 80s and then repeated on Hysis, sometime in 90s then never touched it. Now I have some time to polish up. I am looking for a solved model (oil Refinery, LPG, etc) that I can follow and polish up my rusted skill. Assistance will be appreciated.

    Comparison

    A gas processing plant designed on international codes and standard, now it is to be changed to client Design Engineering Practices (DEPs). I would like to know what documents and drawing will require changes. I have to make a comparitive statement. Is there anyone who has such a matrix or...

    Compressor Discharge PCV

    dcasto, In the part of world that I work, there is no concept of energy saving, climate warming of marching of Greenies. To give you an example a few months ago we were flaring 70 mmscfd from one platform and I have to increase the flaring capacity to 100,000 mmscfd to increase the oil...

    Compressor Discharge PCV

    dcasto Despite of the fact that the valve in not necessarily required but operation insisted to have a back pressure PCV for steady operation of the compressor and I obliged, as a mater of fact the leasing contractor of rental compressor agreed to install.
