The Solution

HPC has developed a long and successful working relationship with Halliburton over many years during which time HPC has designed and specified compressors for many specialised applications which are utilised at sites around the world.  

Halliburton were therefore confident in HPC’s ability to supply the right solution and the decision was taken to invest in a weather-proofed HPC DSD202SFC (SIGMA Frequency Control) Rotary Screw Compressor to replace the diesel compressor used for the dry compressed air injection process.

An important factor in this decision was HPC’s ability to prove and guarantee the performance data and electrical power of their compressor, underlined by HPC providing a declaration of power conformity, despite the limitations of power supply at the site. Crucially, alternative compressor manufacturers were either unwilling, or unable to provide these assurances.

The SFC (SIGMA Frequency Control) feature is another important benefit for this application, providing optimum compressor efficiency through the continuously variable (acceleration / deceleration) speed control and a soft start with no damaging current spikes. For example, the soft, smooth rise in motor starting current from zero to full load without current spikes leads to an almost unlimited motor starting frequency (the number of possible motor starts within a given time period without overheating occurring) and contributes toward significantly reduced component stress. 

The specification also included a fully weatherproofed cabinet with a supply pipe running from the compressor to a large containerised and fully protected buffer receiver and a heatless desiccant dryer ensuring -40ºC and therefore no remaining moisture in the air. The specialised outdoor cabinet features full weather proofing complete with heaters to provide full protection against the rigours of an exposed site which eliminated the need for an additional outbuilding or shielding along with the associated costs.
