MEG, TEG, and Methanol Injection Pumps
Methanol and glycol injection is used in process lines where there is a risk of hydrate formation at low temperatures. We have significant experience in the design and manufacture of methanol and glycol pump skids. Many of our projects are for hazardous area operation and our pump packages comply with very stringent customer specifications.
Ultra High Pressure High Temperature (uHPHT) is relatively new in the offshore industry. Standard operating conditions are up to 690 bar (10,000 PSI) and 300 °C but in uHPHT developments the limits are now being pushed to 1,034 bar (15,000 PSI) and 360 °C as the increased pressure is needed when working at much greater water depths. Significantly, we have recently supplied pump units specifically for use in uHPHT applications. Check out this uHPHT methanol injection pumps case study.
The Methanol Injection Pump
The unique Hammelmann positive displacement process pumps deliver fixed or variable flows depending on the selected drive and control system. These versatile and compact pump packages feature small footprints due to their vertical plunger configuration. They cover a flow range from zero to 100% at flow rates from 0.1 m³/hr up to 179 m³/hr achieving efficiencies of 95% mechanical and 95% volumetric. Volumetric efficiency may vary depending on fluid compressibility.
