Job title: Engineering Manager
Moy Park is an award winning leading provider of fresh, locally farmed poultry in the UK and Ireland and is recognised as one of the largest producers of organic, free range and corn fed poultry in Europe. They supply leading retailers and foodservice providers throughout the UK, Ireland and Europe with a range of high-quality, fresh, coated and added value poultry products.
The start point was a very low flash point which was an ongoing venting problem for many years.
What Moy Park wanted to achieve
A safer system to meet ATEX legislation requirements.
The Global Heat Transfer solution
A closed flash point of 87 Centigrade was the starting point once the first unit was fitted and immediately prior to a batch vent process.
A mark 2 up graded light ends removal unit was installed at the site; this is the first installation of this design in the UK and Ireland by Global Heat Transfer. The older type units would maintain a flash point at a given level, which meant a dilution or some form of regeneration was required.
The new unit, as well as being totally automated for draining off light ends, can also be used as a batch vent (or regenerator as some people know the process). Results show that (as is it owned by the customer as a system upgrade) flash points are maintained in the periods between hiring a “remote regeneration rig”, when they will drop, increasing risk and requiring more expense for re-hire. This new system is also more effective at the batch venting (or regeneration) process.
The results were instant and obvious. Initially, one hour of batch venting was carried out in which 22 litres of light ends were removed from the 20,000 litre capacity system. Nitrogen was removed over night and it switched back to maintaining mode. A further 34 litres of light ends were taken off over 16 hours. The next day a further four hours batch venting was done, removing 22 litres an hour, with the end result being a closed flash point of 151 centigrade which could be maintained at the mode rate of around 2 litres an hour initially and falling back to be maintained at a lower level once a balance is reached. Several months on and an average of 10 – 14 litres per week are regularly removed without having to batch vent, which is maintaining flash points and auto ignition levels comfortably above any caution or action levels.
What Moy Park say
Global Heat Transfer were creative in their response to our challenges and thorough in their implementation to improve our system. I’m really pleased with the results and recommend their services and light ends removal kit to anyone.
