MEG, TEG, and Methanol Injection Pumps
Methanol and glycol injection are 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.
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.
Our Supply History
A few examples of our supply history for MEG, TEG and Methanol injection pump packages includes:
- Norsok-compliant methanol injection pump skid featuring 2 x HDP125 process pumps each capable of 2m³/hr.
- ATEX Zone 1 methanol injection pump system. The scope included a methanol storage tank, multiple discharge outlets with flow transmitters, VSD drive and full touchscreen HMI.
- uHPHT methanol skids for ATEX Zone 2 operation.
- HDP 20V variable stroke reciprocating plunger pump allowing full flow control. A compact methanol pump skid for a platform with severe space constraints.
- MEG injection pump units for a floating production, storage and offloading (FPSO) vessel. These ATEX Zone 2 units underwent a Design Approach 2 study.
- MEG package consisting of several high pressure pumps including MEG subsea injection pump, MEG jockey pump, MEG topside injection pump and MEG booster return pump for the Nova tie-back to Gjøa Project.
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.
