In summary, To convert 25 MMscfd of natural gas to kg/hr at feed conditions of 6900kPa and 298K, you can calculate the standard density from the molecular weight of the natural gas and then use the standard density and the standard volumetric flow rate to directly compute the mass flow in kg/hr.

Hi everyone

i need help converting 25MMscfd of natural gas to kg/hr
i calculated the molecular weight of the natural gas to be 18.94g/mol
the feed conditions are 6900kPa and 298K

i'm pretty sure 1MMscfd = 1180m^3/hr at standard conditions, I'm not sure how to work this out for the feed conditions

You can directly compute your mass flow in kg/hr as follows:

mass flow = standard density X standard volumetric flow rate.

Your standard volumetric flow rate is given as 25 MMscfd

You can figure the standard density from your molecular weight:

standard density = [ MW (natural gas) / MW (air) ] X standard density of air.

What is MMscfd?

MMscfd stands for Million Standard Cubic Feet per Day. It is a unit of measurement used to express the volume of natural gas flowing through a pipeline or a wellhead.

What is kg/hr?

kg/hr is a unit of measurement used to express the mass flow rate of a substance, in this case, natural gas. It stands for kilograms per hour.

How do you convert MMscfd to kg/hr?

The conversion from MMscfd to kg/hr depends on several factors such as the composition of the natural gas and the temperature and pressure at which it is flowing. It is best to use a conversion calculator or consult a gas flow expert for an accurate conversion.

Why is it important to convert MMscfd to kg/hr?

Converting MMscfd to kg/hr is important for accurately measuring and monitoring the flow of natural gas in a pipeline or wellhead. It is also necessary for billing and determining the energy content of the gas.

What are some common uses of MMscfd to kg/hr conversion?

The MMscfd to kg/hr conversion is commonly used in the oil and gas industry for measuring and reporting natural gas production, as well as in the design and operation of gas processing facilities. It is also used in the calculation of emission rates and regulatory compliance.
