The need to measure densities, slurries, and mass flow is extremely important to a dredge owner.  Ronan's non-contact density sensor, in conjunction with a non-contact flow meter, will provide measurements of continuous and totalized mass of solids suspended in liquids.  It can provide the density range for density-compensated mass flow measurements.

FGD SLURRY DENSITY MEASUREMENT

Posted by Ronan Engineering Company

May 14, 2015 1:50:00 PM

Application
A by-product of the burning of pulverized coal in electric power plants is sulfur dioxide (SO2) gas.  To comply with the 1990 Clean Air Act, many plants have installed wet scrubber Flue Gas Desulfurization (FGD) systems to reduce their SO2 emissions.  Due to its low-cost and availability, limestone is the most extensively used reagent.  The limestone slurry reacts with the flue gas in the absorber, removing the SO2.  The limestone in the slurry is converted into calcium sulfite, air is then introduced and oxidizes the sulfite into calcium sulfate which is then filtered and dewatered.  This waste material is then either disposed of in ponds, landfills or sold as ingredients in the manufacturing of gypsum wallboard, cement or used as a fertilizer additive.

It’s hard to believe that just ten years ago, many of us were using flip phones and even… PAGERS! 

Watching your favorite television shows required being in the family living room with a CRT TV and if you were unable to watch a show as scheduled, you had to program the VCR  (Hint for Millennials: Google “Video Cassette Recorder”) to record it.

Enter the SMART PHONE.

8 Starter Steps for Buying an Annunciator

Posted by Ronan Engineering Company

Jan 15, 2015 5:55:00 PM

Buying an alarm annunciator can be a daunting task without a roadmap. This 8-step list should give you a simple start to get your research going in the right direction. 

    1. Figure out if your alarm system is required to have its own logic or will act as a mimic display (no logic) that is driven from an external source. If you're looking for the latter, then direct your search to a "lamp box" or "LED cabinet."  If logic is required (meaning your operators response is dictated by a programmed logic sequence), read on - you're in the right place.

Secure with Scada? Part 2 - Operator Effectiveness

An effective control room should empower the operator to make smart and effective decisions based on information that is provided to them.

The plant operator should be the focal point of any control room design. They are called to make hundreds of decisions every day as problems with supply materials, equipment failures, maintenance programs and production demand high attention - they are the real experts on the daily operation of your plant. In the traditional control room, the control panel was the operator’s window to the process, through which he/she judged how the process was doing and how he/she would respond.

Secure with Scada? - Annunciators as a Reliable Solution

A bold statement recently made by Defense Secretary Leon Panetta garnered some media attention following a cyber attack on Aramco, the world’s largest oil producer.

If you have yet to see the news, click on the CBS video below:

Whether you buy in to the extremity of Panetta’s statement or not, the reality is that even the world’s largest oil producer isn’t immune to the crippling impact of a cyber attack. It reminds us that even the most advanced computer-based SCADA system, PLC or DCS in your plant today isn’t perfect.

Annunciator Backup for Your Emergency Generator

annunciator-with-animation4It’s the type of news that makes us cringe: 

Possible tampering discovered in backup generator at nuclear power plant in California (NBC News)

It was a relief to read that “there was no danger” because the reactors were in shut down mode, however, this event begs us to ask: Why take any risks?

Every step of your critical process presents its own risk for failure - even the emergency generator. An annunciator can account for abnormal conditions even within your emergency generator. A fault alarm in an emergency generator can go unnoticed if there is no proper annunciator system.
