Arca Flow Controls, the US subsidiary of German based Arca Regler GmbH Germany, has delivered five anti-surge valves to Mexico. The valves have been designed for use in several compressor lines that are scheduled to go online in winter 2017 or the beginning of 2018.
The anti-surge globe-type control valves come from the Ecotrol modular parts system, and will be installed to prevent the compressors from pumping during stressful situations in the plant. In addition, they prevent airflow disruption at the compressor blades in order to prevent damage to the compressor.
Each of the compressor lines consists of one single-screw compressor and are driven by a gas turbine. Two lines will be installed in a pipeline station in La Laguna in the state of Coahuila. The other three lines will be set aside for a pipeline compressor station in Villa de Reyes in the state of San Luis Potosi.
When operational, the pipelines will deliver natural gas to CFE (Comisión Federal de Electricidad) power stations as well as industry plants. The compressor stations output serves a pipeline of about 1,500 kilometres length that transports the natural gas from the North into the country’s inland.
The Ecotrol modular parts system undergoes continuous development, with the goal of being able to satisfy the growing demands of the compressor manufacturers market. Arca claims that high flow rate, low noise level, a fast reaction time and high control accuracy are some of the benefits offered by the modular parts system.
