Hydrate Formation Pressure Calculator v 1.1

What Are Natural Gas Hydrates?

At sufficiently low temperature and high pressure, hydrocarbons
can become trapped in water in a solid ice-like crystal. These
crystals are called Natural Gas Hydrates. Hydrates that form in
pipelines can slow or block gas flow and the removal of these
blockages is expensive as well as time consuming.

How Can Hydrates Be Prevented?

• Use software to predict hydrate formation based on composition and
temperature in order to operate at a pressure below the formation
threshold — preventive solution and most cost effective
• Operate at a temperature above the formation threshold
• Remove water from the system
• Add inhibitors that slow hydrate formation
• Add anti-agglomerants which disperse water and prevent hydrates
from aggregating

How Can Lomic Help?

Lomic’s Hydrate Calculator is a Dynamic Link Library (DLL) which is
accessed by a Visual Basic for Applications (VBA) function through a
Microsoft Excel spreadsheet.

After providing a natural gas composition and temperature to the
spreadsheet, you will generate the pressure at which natural gas
hydrates will begin to form in your pipeline. This information is
invaluable when trying to prevent the troubles associated with hydrate
formation without paying for inhibitors and anti-agglomerants.

The calculation is performed according to GPSA standards using the
Katz K-factor method as presented in the GPSA Engineering Data
Book (1998). This method uses vapor-solid equilibrium constants
combined with mole fractions to find the pressure of gas-hydrate
equilibrium at which formation begins.
