In our latest project , we were asked to help a turbine manufacturer who were looking to test operation when fueled with methanol
Methanol – known as a future fuel can help to reduce carbon emissions by 65 % to 95 % depending on the feedstock and conversion process used . That ’ s one of the highest potential reductions of any fuel currently being developed to replace petrol , diesel , coal and methane .
It is a multi-purpose fuel that can be used on its own , blended with other fuels or for producing fuel additives which improve engine performance . It can also be used in fuel cells , which convert energy to electricity .
Supplying a methanol turbine feed pump North Ridge were contacted by a gas turbine manufacturer who was looking for a proven methanol feed pump to pump liquid methanol at range of temperatures from -20 ° C to - 40 ° C .
The flow rate would be around 30L / min at pressures of up to 3 bar and was being used to test a newly developed turbines performance . They would vary the pump flow utilising both 50hz and 60hz frequencies to increase flow but required the same consistent pressure to ensure that turbine performance was maintained .
For this particular project , we supplied our heavy duty vane pump the NRBAL2R which was longcoupled in cast iron and mounted on a baseplate connected to an ATEX 0.75Kw motor .
The NRBAL2R series of vane pumps is a high performance model commonly used in applications
Rotary vane pumps can bring significant benefits in applications where high performance and reliability are required with minimal loss of downtime .
where pumps are ran continuously such as in tank farms , refineries or oil processors pumping a variety of liquids which can be corrosive , flammable and low lubricating .
Consequently this design of pump is built with double mechanical seals to ensure almost zero chance of leakage of volatile fluids , as well as longer service life without affecting the units overall size . Safe fluid handling is also ensured through the use of the integrated relief valve mounted on the pump head preventing the pump being damaged from excess pressure . This model is also equipped with a double set of bearings ensuring rotational loads are evenly distributed . The pump was operated by a geared motor running at only 470rpm further ensuring any wear was kept to a minimum .
Rotary Vane Pump Benefits Rotary vane pumps can bring significant benefits in applications where high performance and reliability are required with minimal loss of downtime . They are easy to maintain , and provide consistent flow across varying viscosities at different pressures .
Our range of NR-BAL rotary vane pumps for instance , are positive displacement volumetric pumps with a maximum working viscosity of 10,000 cSt . This means they can easily handle the vast majority of low to medium viscosity fluids without loss of performance .
Thanks to their efficiency , reliability and heavy-duty design our rotary sliding vane pumps are perfect for volatile , flammable liquids used across industry . They are also perfect for use with alternative or future fuels as discussed .
If you ’ re looking for proven pumps for methanol transfer or any kind of alternative fuel handling in a variety of applications , speak to North Ridge Pumps to see how we can help .
