Metering pumps for gas extraction

Product catalog summary

Introduction
Petrobel, operating the Baltim South West 2X gas well off the Egyptian coast, faced challenges in maintaining efficient gas flow due to hydrate formation in pipelines. Hydrates, ice-like solids formed from water and gas, can block pipelines, leading to reduced capacity and potential ruptures.

Hydrate Prevention Strategy
To prevent hydrate formation, Petrobel opted for glycol injection to alter thermodynamic conditions. They collaborated with Exakta to implement a glycol injection solution using Nexa Series pumps.

Solution Implementation
Exakta provided 12 Nexa Series packed plunger dosing pumps with a multi-head setup for glycol dosing. These pumps were mounted on a rig for easy transport and installation on an offshore platform. The Nexa Series was chosen for its flexible configuration, dosing accuracy, and reliability, suitable for harsh environmental conditions.

Benefits
The installation allows Petrobel to operate without concerns over hydrate formation, reducing maintenance costs and increasing profitability.

Nexa Series Features

PVDF diaphragm for chemical compatibility
ATEX approved for explosive atmospheres
Multiple head execution with various mechanism sizes and gear ratios
Compliance with API 675 standards
Flow rate up to 7,500 l/h and pressure up to 660 bar
Fluid temperature range from -10°C to 90°C (extendable to -40°C to 150°C)
Manual and automatic flow-rate adjustment
Zero-leakage profile
Multiple mounting options

Conclusion
This case study highlights Exakta's role in providing long-term, cost-effective solutions for the oil and gas industry, enhancing operational efficiency and reducing costs.

Offshore gas field prevents pipeline blockages with Exakta chemical injection solution When Petrobel, the operator of the Baltim South West 2X gas well off the Egyptian coast, struck a 102-metre gas column, one of its priorities was to ensure efficient and continued flow within pipelines during extraction. A major obstacle Petrobel faced was the common problem of hydrates, which are ice-like solids that form when water and gas combine and crystallize in a high-temperature, low-pressure environment. The formation of hydrates in oil and gas pipelines causes reduced capacity and eventually a complete...

Following a comprehensive assessment of the process between Exakta and Petrobel, it was decided to use 12 Nexa Series packed plunger dosing pumps with multi-head setup for glycol dosing. These were mounted on a large rig that could be transported as a complete unit to a fixed offshore platform ready for installation. Nexa Series pumps were selected for their flexible configuration, superior dosing accuracy and excellent reliability, representing the best solution to cope with the harsh environmental conditions and fluctuating temperatures encountered in oil and gas applications. This installation...
