    Pressure Relief Valve For Fire Water System

    hi all, i need to perform sizing calculation of Pressure Relief Valve (PRV) for Fire Water System. According to NFPA 20, if 121% of shuttoff pressure + max static pressure exceeds the rated system components, PRV shall be installed. in my case, the pressure is above the max allowable pressure...

    Crude Oil Dehydration

    Dear all, I want to ask about crude oil dehydration processing. The wellstream which usually contains crude oil and water will be separated in Free Water Knock Out (FWKO) to separate the free water. The dehydration process is needed in order to reduce the emulsified water. As far as I know...

    compressor selection and configuration for natural gas

    hi all, i want to ask about how to choose compressor type and their configuration ( 1x100%, 2x50% or 3x30%). this is for the natural gas field development ( 96% Methane, 65 MMSCFD, specific gravity 0.57, ACFM 3025 ) at the beginning of production, in the gas processing plant, the suction...

    pressure relief system calculation

    hi all, i am new in studying pressure relief system. i have tried to read API RP 521 and GPSA section 5 "relief system". but it lacks of manual calculation example, so i have confusion to apply the equations in those codes. 1. is there any handbook which provides the example of designing...

    separator design consideration

    hi all, i need to design a two phase separator to separate natural gas 60 MMSCFD, 200 F, 400 psig from 1000 barrel water per day. i have some questions to be asked : 1. how much separator that i need to design ? i mean, do i need to design 2 units of separator (@ 30 MMSCFD) or is it enough to...

    Low temperature piping and pipeline

    hi all, i want to evaluate the capability of existing piping (ASTM A 106, Sch 40) and pipeline (API 5L X65 sch 80) is it capable to be operated in low temperature (33 F) and pressure (530 psia) ? as far as i know, low temperature will give significant effect in brittleness, but how do i...

    Gas Dehydration

    hi All, i want to know how do we define the best way to dehydrate gas from 20 lb/mmscfd to 4 lbb/mmscfd, by using Glycol Dehydration Unit or Molecular sieve ? as far as i know molecular sieve is more expensive than using glycol, but what is the limitation of using molecular sieve ? dew point or...

    Reciprocating compressor capacity

    Hi, I just graduate and I am new in a real engineering work. I dont have experience and I need your help :) we want to use existing reciprocating compressor, the calculated reciprocating compressor capacity at suction condition (55 MMscfd) is higher than the natural gas supplied to compressor...
