Positive Crankcase Ventilation

This week I am going to share with you a recent application I did for a customer with a stationary gas compressor. Transporting natural gas through pipe lines across the nation requires substations along route to overcome pressure loss. Some of the gas is used to power up engines that turn large compressors to push the gas further down the line.

With all combustion engines some of the combustion gasses along with carbon soot gets past the piston rings and into the crankcase. Common practice is to vent this back into the intake manifold using the vacuum in the manifold to draw it in.

In this case, the customer wanted to filter the “blow by” before returning it into engine. The pressure drop across the filter impeded the flow too much to be effective.

They installed an EXAIR Line Vac  model HT6063 High Temperature line Vac to generate a vacuum to pull the gasses through the filter. Problem solved. It was a simple solution to a major problem.

Do you have an overwhelming problem? Give one of our application engineers a call and the will do their best to find you a simple solution.
