Methanol and Glycol Injection Pumps

Methanol and glycol injection is used in process lines where there is a risk of hydrate formation at low temperatures. High pressures are required to overcome friction losses in subsea pipelines where the well head can be up to 100 kms from the platform.

We have significant experience in the design and manufacture of methanol and glycol pump skids and have developed many pump skid packages to comply with hazardous area regulations and some very stringent customer specifications.

High Pressure High Temperature (HPHT) is relatively new in the offshore industry. Standard operating conditions are up to 690 bar (10,000 PSI) and 300 °C, but in HPHT 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 greater water depths. We have recently supplied pump units specifically for use in HPHT applications.

The High Pressure Pump

The unique Hammelmann ‘Zero Leak’ positive displacement process pump delivers fixed or variable flow dependent on the selected drive and control system. These versatile and compact pump packages with small footprints cover a flow range from zero to 100% at flow rates from 100 lph up to 160 m³/hr achieving efficiencies of 95% ME and 95% VE (VE may vary depending on fluid compressibility).
