Environmental legislation dictates that emissions from incinerators have to be continuously monitored, so when a problem occurred with the on-line analyser at a municipal waste incinerator, it was vitally important that a solution was found quickly so that the plant could continue to operate.
Coincidentally, staff from Cardiff and Birmingham based Environmental Compliance Limited were onsite carrying out compliance monitoring at the time and they immediately contacted Ashtead Technology to arrange an urgent next-day rental for two Horiba PG250 portable multi-gas analysers.
Rhodri Jones, Senior Team Leader at Environmental Compliance, said: “What began as a typical ‘QAL2’ compliance monitoring session quickly transformed into a potentially serious situation for our client. To enable the continuous monitoring of the incinerators we contacted Ashtead Technology, having been impressed with their service on a previous occasion. However, in this instance we obviously needed the instrumentation at extremely short notice.
“Thankfully, Ashtead was able to guarantee delivery of the Horiba PG250s to our client’s site the following day. For the next three days the monitoring was undertaken with the rented equipment from Ashtead, resulting in total cost savings of almost £½m; the estimated cost of closing down the plant for 3 days.”
The portable and MCERTS approved Horiba PG250 is capable of simultaneously measuring up to five separate gas components. It is ideal for CEMS certification testing of NOx, SO2, CO, CO2, and O2 or for use when stack gas emissions must be monitored periodically at one or multiple stacks.
Housed in a single lightweight and fully portable case, it utilises the same measurement principles as permanently installed Continuous Emissions Monitoring Systems (CEMS) - unlike other portable gas analysers that rely upon electro-chemical sensors.
Ashtead Technology's Alan Hasson, added: “CEMS instrumentation represents an important market for us and we have made considerable investment in our fleet of CEMS-related equipment over the last two years to ensure that we have the very latest technologies available.
“A major benefit of renting is that customers have access to the most up-to-date instrumentation on the market, whilst avoiding the capital cost associated with buying outright. This case is also a perfect example of the rapid turnaround time that we are able to achieve in emergency situations.”
