Gas Gathering and CO2 Reinjection Compressor - Thermodynamic Merging of Streams with Different Temperatures and Pressures

[wennanlong]

Description:

I've encountered an issue in the current implementation of the gas gathering and CO2 reinjection compressor processes. Both processes involve combining multiple incoming streams with different temperatures and pressures. The existing method does not handle the merging of these streams in a thermodynamically consistent manner, leading to potential inaccuracies in the process simulation.

Affected Processes:

1. Gas Gathering
2. CO2 Reinjection Compressor

Expected Behavior:

When combining incoming streams with different temperatures and pressures in the gas gathering and CO2 reinjection compressor processes, the system should:

1. Account for the mass and energy balance between the streams.
2. Merge the streams in a thermodynamically consistent manner, which considers the physical properties (such as temperature, pressure, enthalpy, etc.) of the individual streams.
3. Provide accurate and reliable results in the simulation output for further analysis.

Current Behavior:

The current implementation does not properly account for the differences in temperature and pressure between the incoming streams, causing inconsistent and potentially inaccurate results in the gas gathering and CO2 reinjection compressor process simulations.

Solution:

This issue has been solved in the OPGEE v4
