Disastrous Dinners Survey

I presented the suggestion to members of the IChemE committee tonight and the feeling was positive. The next stage is to publicise the survey:

Disastrous Dinners: Part social event, part technical talk and part workshop. Something for everyone!

We are looking to host a series of these events next year ...

Stale Alarms

I have previously written about alarms and following on from yesterday's post I want to write about stale alarms.

These are alarms that initially come in, but for some reason the operator cannot remove them. They are usually classed as stale if they have been on the alarm page ...

What is an Alarm?

I have previously written about nuisance alarms particularly during shutdowns, but today I want to cover the fundamental questions of what an alarm is and what it is not.

The definition of an alarm is:

Alarm: An audible and/or visible means of indicating to the operator an equipment malfunction ...

Last Good Value from PI

Within our plant, we use the PI as our main plant historian. We can access process history using PI datalink to import the data into excel. There was a situation last week where I was attempting to create a dashboard view of the process.

This is assuming you have some form of local storage ...

What Does a Control Engineer Do?

Today we had a school pupil shadowing our team, trying to work out what a carrier in chemical engineering would be like. Earlier in the week she spent time with developement and optimisation engineers but today it was the turn of the automation team to explain what control engineers do ...

Typeup of Proof Testing Webinar

Yesterday I viewed a webinar on proof testing1 organised by IChemE.

The presentation was a good overview and went at a decent pace for following along but was too fast for me to take any decent notes.

Below is a quick writeup of what I took from the session ...

Vanessa Sutherland - Trevor Kletz Memorial Lecture

Vanessa Sutherland was1 the Chair of the US Chemical Safety Board (CSB) and delivered the fourth Trevor Kletz Memorial Lecture2 at the IChemE hazards conference.

I did not attend the lecture in person however the IChemE have put a video of the presentation online3.

Steam Heating on Ceres

Yesterday I watched the latest video from the Isaac Arthur Science and Futurism youtube channel on Colonizing Ceres.

I have been enjoying these videos recently which offer hard sci-fi without any (or very minimal) plot. They look at what would be possible in the future assuming known science and only ...

APC vs Toddlers

Over the last few weeks, I have been commissioning a couple of new Advance Process Control (APC) schemes within the refinery and it occurs to me that this is very similar to looking after a toddler in the house.

Watching a Toddler

When looking after the little one, you can ...
