graphite steam jet vacuum pump
An efficient and compact graphite steam jet vacuum pump for the production of Active Pharmaceutical Ingredients.
Mersen has offered a multi-stages graphite steam jet vacuum pump with a highly optimized design to a major producer of Active Pharmaceutical Ingredients in France.
Steam jet vacuum pumps are used to remove gas molecules from a volume in order to leave behind a partial vacuum. Steam jet ejectors offer a simple, reliable, low-cost way to produce vacuum.
They are especially effective in the chemical industry where an on-site supply of the high-pressure motive gas is usually available.
Steam jet ejectors are considered a great alternative to mechanical vacuum pumps because no source of power is required other than the motive gas. They have no moving parts and are therefore reliable, easy to install, to commission, to operate, and to maintain.
Context
A major producer of Active Pharmaceutical Ingredients in France had to replace its failing 25 years old graphite steam jet vacuum pump.
Challenge
The previous steam jet vacuum pump was extremely compact. The new graphite steam jet vacuum pump has to fit in the very same footprint while in the meantime the requirements of PED 2014/68/EU lead to larger pressure vessels and equipment than before.
Solution
Mersen has offered a multistage graphite steam jet vacuum pump with a highly optimized design. Instead of having one condenser after each steam ejector, the heat transfer surface of a single larger condenser has been split into 2 totally separated condensation areas and operating at two different vacuum levels.
This design allows major space savings since it necessitates only one condenser and also less piping.
The customer received a new, extremely compact, PED compliant, graphite steam jet vacuum pump to replace its old one.
