This post would like to bring to you a very special software for Chemistry Periodic Table. It has been developed by Paul Alan Freshney. Chemistry Periodic Table software has been there since 2002 and latest version is 3.7, border="0" released on AUGUST 31, 2008 (as of now).
The application contains ALL the elements of the Periodic Table along with images of the elements in their natural state, as well as lots of other information and interactive displays.
There are some very interesting features in this Chemistry Periodic Table :
- Detailed information on each element
- Details of isotopes and allotropes
- Details of important compounds
- Details of reactions with water, air, halogens and acids
- Images for each element (300+ images in total) including valence and crystal stucture diagrams
- Glossary of terms
- Graphs of important element properties and trends
- Biographies for the important scientists and element discoverers
- View the states of the elements at any temperature (from 0 - 6000k)
- XP style support
- Search through all content
- Electron shell diagrams of each element (including orbital images)
- Atomic width diagram
- Toolbox, 330 physical constants and over 6400 formulae
- Element names and the majority of the applications buttons are now available in eight different languages. Unfortunately there is just too much text for me to translate (100000+ words).
Some snapshot of this software.
You may add your own content to the software as well.

Plant debottlenecking project involve increases in capacity (Q) but keeping pressure (P) profile to maintain process performance required installation of new pump either in series or in parallel in order keep existing pressure profile. Optimization of new pump in series or parallel operation will be conducted. The optimization will involve addition of two pumps curve either in series or parallel.
The following Series / Parallel Pump Calculator (EXCEL) has been generated to allows to mix two pump curves and produce a combined performance curve of identical and similar pumps (or pumps with different performance) operate in series and parallel. It also allows you to enter system curve so that you can evaluate their performance. In this Calculator, the unit for head can be feet, meter, mmHg and flow can be gpm, m3/h, etc

One fine day, you are in the meeting and you have been asked to about the properties for steam at 10 barg & 200 degC. You can either - use the excel add-on Water97_v13 as introduced in "Conduct Steam-Water Balance MANUALLY using Water97_v13"
- use the Steam-Condensate calculator as introduced in "Useful Steam - Condensate Calculator"
- Steam table (manual calculation)
Use Excel may required to remember the function and steam-condensate may required you to login to internet. Sometime the server which steam-condensate calculator may down for some reason. Using steam table would definitely time consuming. One of way is to use the SteamTab steam-condensate software which is rather handy for you.
Similar to the excel add-on, you may obtain steam-condensate properties for subcooled, saturated and superheated condition. In additional to common properties, it also calculated other parameter such as surface tension, Gibbs energy, etc.
If you have problem in obtaining this handy tool, please drop me a note.

Recently i was supervising a young engineer in the design of Steam - Water system for an LNG plant. This kind of system can be easily simulated in any Process Simulator such as HYSYS, PRO-II, etc and generate a Heat & Material Balance (HMB). If you have several years experience, you may notice that nowadays young engineer tends to use Process simulator and ignoring the basic behind. Due to this reason, i insisted the young engineer to conduct Heat & Material Balance for Steam -water system MANUALLY using Excel spreadsheet. Without any surprise the young engineer having difficulties... In "Useful Steam - Condensate Calculator", there is an Excel Add-in (Water97_v13.xla or Alternative download) available FREE for download, is very useful for calculating thermodynamic and transport properties of water and steam using the industrial standard IAPWS-IF97. In this post, i will elaborate a little bit on the method to conduct steam-water balance manually using above add-in.
Material Balance :
For M1 :
M1 & M2 can be adjusted until the enthalpy difference between INLET section (e.g. M1 x h1,vs + M2 x h2,T ) and OUTLET section (e.g. M3 x h3,vs) equal to zero AND M1+M2 = M3. The adjust function can be easily setup using GOAL SEEK feature in EXCEL.
Details may refer to following image.
It is rather simple programming as seen from above and no simulator is required.
Problem statement :High pressure steam (HS) at 20 barg @ saturated condition mix with Boiler Feed Water (BFW) at 15 barg @ 60 degC to 1000 kg/h Low Pressure Steam (LS) at 3.5 barg @ Saturated condition. Find quantity of HS & BFW.
Material Balance :
M1 + M2 = M3Heat Balance :
M2 = M3 - M1
M1 x h1,vs + M2 x h2,T = M3 x h3,vsa) For HS Steam : Get Specific enthalpy (h1,vs) for Saturated steam at pressure 20 using enthalpySatVapPW (P)
M1 x h1,vs + (M3-M1) x h2,T = M3 x h3,vs
M1 x h1,vs + M3 x h2,T - M1 x h2,T = M3 x h3,vs
M1 x h1,vs - M1 x h2,T = M3 x h3,vs - M3 x h2,T
M1 x (h1,vs - h2,T) = M3 x (h3,vs - h2,T)
M1 = M3 x (h3,vs - h2,T) / (h1,vs - h2,T)
[e.g. enthalpySatVapPW(20+1.01325)]b) For BFW : Get Specific enthalpy (h2,T) for Subcooled liquid at 15 barg @ 60 degC using enthalpyW(T,P)
[e.g. enthalpyW(60+273.15, 15+1.01325)]c) For LS Steam : Get Specific enthalpy (h3,vs) for Saturated steam at pressure 3.5 using enthalpySatVapPW (P)
[e.g. enthalpySatVapPW(3.5+1.01325)]d) As M3 is 1000 kg/h, M1 & M2 can be obtained by modeling it in the EXCEL sheet.
For M1 :
=1000 * (enthalpySatVapPW(3.5+1.01325) - enthalpyW(60+273.15,15+1.01325))/ (enthalpySatVapPW(20+1.01325) - enthalpyW(60+273.15,15+1.01325))For M2 :
= 1000 - M1Another method is using GOAL SEEK in EXCEL sheet...
M1 & M2 can be adjusted until the enthalpy difference between INLET section (e.g. M1 x h1,vs + M2 x h2,T ) and OUTLET section (e.g. M3 x h3,vs) equal to zero AND M1+M2 = M3. The adjust function can be easily setup using GOAL SEEK feature in EXCEL.
Details may refer to following image.
It is rather simple programming as seen from above and no simulator is required.
Young engineer is always encourage to conduct above calculation as least 2-3 times so that you are sure yourself understand heat & material balance in depth. By doing this kind of calculation, you will surprise your depth understanding. Later stage, you can always simulate balance with process simulator to save time.
For those who are interested in the EXCEL spreadsheet, you may drop a note to me.

Pressure relief load determination is a common task carry out by process engineer whilst Pressure Relief Valve (PRV) sizing and selection is normally conducted by vendor with the coordination with Instrumentation Engineer (most companies). However, pre-selection and sizing of PRV may need to be carried by process engineer during conceptual and Front End Engineering Design (FEED) stage in order to provide best estimate of information for Flare system design. Thus, PRV sizing is considered one of the important task for process engineer.
There are many Pressure relief valve vendors offer free PRV sizing program. However, a few out there are really good, reliable and impressive. Farris SIZEMASTER, Dresser CONSOLIDATED SRVS and Tyco PRV2SIZE consider one of those.

Carbon Dioxide (CO2) is known as one of industrial waste gas causing global warming...there are number of measures are implemented to reduce global warming. CO2 reduction measures are CO2 capturing, reinjection into aquifer, injection into reservior for well maintenance, gas injection for enhanced oil recovery (EOR), etc.
Above efforts will reduce CO2 release into atmosphere. However, recycling CO2 will increase quantity of CO2 in oil and result serious corrosion problem. Hence it needs to be removed from the flashed gas (from unstabilised oil). CO2 removal technology using amine absorption has been used for many years. Recently i found a website (OGT) where the founders, Ralph Weiland and Jack Dingman are those experts in this technology.
Optimized Gas Treating, Inc. (OGT) was established in 1992 by Ralph Weiland and Jack Dingman for the single purpose of providing a commercial version of a Windows-based software package for simulating acid gas removal with aqueous alkanolamines that uses a fundamental mass and heat transfer rate approach to column modeling. ProTreat™ is the culmination of more than 30 years of research in gas treating supported by government and industry in both academic and commercial environments. ProTreat is our sole product. Consequently, it receives our undivided attention in maintaining and enhancing its capabilities so that it remains the premier software package for gas treating with amines. OGT’s principals are recognized world experts in most aspects of gas treating — they offer a total of nearly 60 years of relevant experience.
