Fuel Pressure Increase

[ngvfleet]

I have a Natural gas fueling system and I need to boost the pressure of the NG from 50 psi at the tank to 100 to 150 psi for delivery and consistent pressure at the engine. any suggestions?

Umm

Use a compressor.

Cool the gas a lot before you pump it.

Make sure the container will withstand the maximum pressure you will reach after a heat soak on a hot day with a very good safety factor as a rupture will be quite spectacular.

If you actually ask your question which it seems is actually

I wish to pump CNG to 150psi

Can anyone recomend a source of a pump you might get a response from someone who does instead of us both wasting the time I put into this.

I don't know a source.

Have you tried google

Maybe I was not clear. the fueling system on the vehicle is releasing the gas from the tank to the engine at 50 PSI. I need to boost the pressure on board from the tank to the engine to a max of 150 psi. I have tried google to find the type of compressor/supercharger or other type of booster. can anyone recommend either a type/supplier of compressor or gas intensifier for this particular application.

Sounds to me like you just need a 150 PSI pressure regulator. Surely your tank pressure is over 150 PSI.
