Ankur's_Chemical_Engg_Blog > Fixed Water Spray Demand Calculations For Fire Protection Of Tanks / Vessels

Posted ankur2061 on 12 July 2012 - 02:07 AM

Of late I have developed quite a bit of interest in HSE engineering and specifically related to Loss Prevention protection and I have been going through a lot of literature related to Loss Prevention and specifically related to fire protection.

When we talk of fire protection, some of the most comprehensive guidelines and standards developed for fire...

Ankur's_Chemical_Engg_Blog > Faq On Process Design Engineering

Posted ankur2061 on 12 August 2010 - 08:53 AM

I have encountered a lot of fresh chemical engineering graduates from college who joined as "trainees" in the engineering consultancy field and inevitably they have a lot of questions on what process design engineering is all about?

Some of the frequently asked questions (FAQ's) are what are the activities that a process design engineer do,...

Ankur's_Chemical_Engg_Blog > How To Write A Plant Operating Manual

Posted ankur2061 on 13 July 2013 - 06:48 AM

Most Process Engineers, specially the senior process engineers are required to write a plant operating manual for a new greenfield project during their career. Mind you, this is quite different from updating an existing operating manual for a brownfield project where the scope of the project is modification and debottlenecking. Updation of an existing ope...

Ankur's_Chemical_Engg_Blog > Perforated Pipe Distributor Sizing Calculations

Posted ankur2061 on 16 May 2013 - 03:48 PM

Perforated Pipe Distributors have been discussed many times on “Cheresources”. How to design a perforated pipe distributor also known as a sparger has been a frequent question on the forum. Some general replies without providing in-depth methodology of sizing a distributor can be seen in the queries raised.

Perry’s Handbook (8th  Editio...

Ankur's_Chemical_Engg_Blog > Gas Boot Sizing Upstream Of Fwko Tanks

Posted ankur2061 on 28 April 2014 - 12:34 AM

Gas Boots are provided upstream of a Crude Oil Dehydration tank in order to degass the crude oil before it enters the dehydration tank. Entrained gas in crude oil disturbs the settling process in a dehydration tank and it's removal is required to ensure quick and effective settling for separating bulk water in crude oil dehydration tanks also referred com...

Ankur's_Chemical_Engg_Blog > The Flip Side Of Engineering Standards And Practices

Posted ankur2061 on 07 October 2013 - 11:40 AM

Dear All,
 
I like to keep myself abreast of the latest engineering standards and practices from international organizations (API / ISO) and from engineering / operating companies. The best thing about them is I don't have to overload my memory trying to remember established engineering and design practices which are generally well...

Ankur's_Chemical_Engg_Blog > Minimum Safe Recyle Process Flow Schemes For Centrifugal Pumps

Posted ankur2061 on 01 January 2013 - 06:46 AM

On the eve of the new year designated as 2013 as per the Gregorian calendar, I wish the members and readers of "Cheresources" a very happy and prosperous new year. Before moving on to the topic at hand, I wish to express my sincere thanks to Chris Haslego and Art Montemayor for providing this wonderful gift of "Cheresources" to the...

Ankur's_Chemical_Engg_Blog > Safety Rules To Be Followed For A Field Visit By A Process Design Engineer

Posted ankur2061 on 02 August 2012 - 03:27 AM

Most new process engineers working in design consultancy are unaware of the safety rules that need to be strictly adhered when making a field visit to a chemical process unit whether it be an upstream oil and gas processing installation, a refinery or a petrochemical plant. Today's blog entry tries to expalin some basic safety rules for a site visit. I...

Ankur's_Chemical_Engg_Blog > As-Built Piping & Instrument Diagrams

Posted ankur2061 on 06 July 2012 - 02:47 AM

Not many young entrants in process engineering would be aware of this aspect of engineering and today's blog entry tries to put in perspective what "As-Builting" is all about.

Most of you are aware that during the engineering phase an important task by the process engineer is to prepare "Piping and Instrument Diagrams", in short...

Ankur's_Chemical_Engg_Blog > Some Utility Consumption Estimates

Posted ankur2061 on 14 February 2012 - 10:33 AM

As part of preparing a process discipline manual for one of my previous organizations, one section that I had prepared was "Guidelines for Preparation of Utility Summary". This document besides containing an excel template for utility summary also had some guidelines for determining the consumption of utilities such as instrument air, cooling...

Ankur's_Chemical_Engg_Blog > Careers Options For Chemical Engineers With Special Emphasis On Females

Posted ankur2061 on 04 June 2011 - 11:28 PM

Many young lady engineers ask questions about their career options specially in the context of various options in the chemical process industry. In this blog entry I would like to take the opinion of the young ladies who are just starting their careers as chemical engineers as well as present the work conditions of the different areas where chemical...

Ankur's_Chemical_Engg_Blog > Solid-Liquid Mixing In Agitated Vessels (Just Suspended Speed)

Posted ankur2061 on 08 April 2016 - 06:29 AM

Dear All,

Solid suspension and dispersion in a liquid is an important operation carried out in mixing systems. The primary objective of solid-liquid mixing is to create and maintain a solid-liquid slurry, and to promote and enhance the rate of mass transfer between the solid and liquid phases. Such processes are typically carried out in mechanically agit...

Ankur's_Chemical_Engg_Blog > Heat Transfer In Buried Liquid Lines (Stagnant Liquid)

Posted ankur2061 on 13 February 2016 - 01:42 PM

Dear All,

My earlier blog entry on heat transfer in buried liquid pipelines related to temperature reduction of the flowing liquid at a certain distance from the pipeline inlet.

Let us think of a buried pipeline or pipeline section where the liquid flow has been stopped and the liquid is now in a stagnant condition in the pipeline or pipeline section. L...

Ankur's_Chemical_Engg_Blog > Natural Gas Pipeline Blowdown Time Calculation

Posted ankur2061 on 02 June 2013 - 07:31 PM

I have posted a lot of excel spreadsheets on the Cheresources community related to process engineering calculations. I also have posted blog entries where I have outlined the steps along with equations to build an excel spreadsheet for various calculations.
 
The idea of posting blog entries with equations and calculation steps is to encourage young...

Ankur's_Chemical_Engg_Blog > Comparing Iso13709 / Api 610 With Ansi / Asme B73.1 Centrifugal Pumps

Posted ankur2061 on 05 December 2012 - 02:50 AM

I am not a rotating machinery specialist but a process engineer. Today's blog heading probably has more relevance to a rotating machinery specialist. Nevertheless, I felt that process engineers are also entitled to know the difference between these two distinct categories of centrifugal pumps used worldwide for a majority of pumping applications...

Ankur's_Chemical_Engg_Blog > Liquid Pipeline Surge

Posted ankur2061 on 13 September 2012 - 03:08 AM

Pipeline Surge has been a hotly debated topic on "Cheresources". During one of these discussions I had said that I would try to compile a blog entry related to pipeline surge possibly with an excel workbook. Today's blog entry discusses pipeline surge sans the excel workbook. I expect the young process engineers to develop their own...

Ankur's_Chemical_Engg_Blog > Inter Discipline Check - It's Definition, Description And Importance

Posted ankur2061 on 19 July 2012 - 03:28 AM

I had been thinking of writing on the subject of "Inter Discipline Check", familiar to many experienced engineers working in the engineering design and consulting field by its acronym "IDC", for quite some time, and today seems to be quite appropriate.

Today's blog entry is specifically targeted for new chemical engineers joining...
