A high-pressure methanol multihead metering system will prevent hydrate formation on flow lines from the Zinc field subsea template in the Gulf of Mexico to the nearby Alabaster platform. To prevent gas hydrate formation at producing temperature and pressure, Exxon specified the installation of methanol injection from the Alabaster platform to the Zinc template. The original idea employed a single-head injection system with one metering head on Alabaster and one injection point on Zinc. However, the flow range (and redundancy requirements) were too great for a single-head injection system to function properly. Therefore, Exxon and Bran + Luebbe Inc. developed a custom-designed, multiheaded metering system for high-pressure methanol injection.
