Nitrogen generators from Parker domnick hunter improve safety and efficiency for Scottish Power

The company depends on a constant source of nitrogen on-site for a variety of applications to ensure safety and quality and have successfully operated a MAXIGAS106 generator for around 10 years in a purpose built enclosure at their site at Lindholme near Doncaster, UK. Due to continued success and growth however, Scottish Power expanded this site and their nitrogen requirements soared.

MAXIGAS generates nitrogen from compressed air and is the safe, cost effective alternative to other nitrogen gas sources due to an exceptionally low lifecycle ownership and elimination of cylinder refills and associated charges. Additionally, MAXIGAS provides exceptional nitrogen at a controlled flow, pressure and purity.

The MAXIGAS110 model was installed to complement the existing equipment and meet the increased demands. With a production rate of 34 m3/hr, purity rate of 2%, a 500 litre buffer vessel and 2,000 litre nitrogen storage vessels, the additional generator offered the perfect solution for Scottish Power.

Alan Penman, a representative from Scottish Power comments, “We have been delighted with the performance of the upgraded package since installation. It has allowed us to operate the site with total confidence in our nitrogen supply and the systems ability to meet all of the stringent demands.”

The installation has now operated successfully for over twelve months and was carried out by fully trained and experienced domnick hunter engineers. The MAXIGAS110 now operates as the lead generator and the MAXIGAS106 functions as the back-up.

Alan continues, “An additional benefit of the upgrade means that we now have extra capacity and can use the MAXIGAS generators to supply ‘purge’ gas to the sites gas pipelines and vessels when preparing to break containment e.g. when changing filters or inspecting vessels.”

Alan also adds, “Furthermore, servicing has minimal impact as we have the ability to operate one generator while the other is being serviced. This reduces our reliance on bottle supplies and also offers added safety benefits, as personnel can now work with the equipment without exposure to high pressure gas cylinders, regulators and hoses.”

Additional Parker domnick hunter products such as filters are also operational throughout Scottish Power’s Lindholme production facility.
