Cook Compression

Since 2001, the Cook Compression Projects Group has helped customers define efficiencies, improve reliability, advance safety, and realize OPEX and CAPEX savings. The group’s expertise lies in long-term, multi-functional projects that require comprehensive understanding of both equipment and processes – and that significantly affect the customer’s bottom line.

From the group’s more than 420 projects to date, here is just one example:

Achieving Capacity Increases with Existing Equipment

Late in 2016 the Cook Compression Projects Group was challenged with the task of identifying practical opportunities for an end user to free up one or more compressors in its fleet of 15+ identical operating compressors located across several sites. The compressor operators had noted that the units were at their capacity and mechanical limitations. Having spare or standby equipment would provide flexibility to plan and perform compressor maintenance without halting production, significantly improving up-time and operational reliability and reducing operating expenses for the plants.

The compressor OEM offered two options: add a new complete compressor train to each site or bore the cylinders oversized to increase the flow of each compressor. A technical review by Cook Compression identified a third solution: upgrade the existing compressors’ pistons, rods, valves and wear parts. The upgrade would leave the cylinder bore size the same, preserving the cylinder’s maximum allowable working pressure (MAWP). It would also eliminate the need to remove the cylinder for boring, saving valuable runtime.

Late in 2017, Cook Mechanical Field Services applied the upgrades to the first compressor. The two-day turnaround included installation of new piston and rod assemblies, new Manley® valves with suction unloaders, and rebuilt packing and wiper cases, as well as modifications to the compressor heads.

The customer’s equipment analyst has confirmed that the predicted ~2mmscfd (10%) increase in flow has been achieved, without exceeding the mechanical limits of the driver and compressor frame rod load limits. This 10% increase in flow per unit is enough for the end user to place one compressor at each site on standby and still meet the plants’ flow requirements.

Projects Group Introduces Effective Emissions Solutions

Another recent project on the U.S. West Coast addressed emissions reductions and engaged a continuum of customer contacts from the corporate Environmental Team leaders to the field processing plant personnel.

The Projects Group handled the installation of low-leak packing, as well as the documentation of compliance with current California EPA regulations and the training of on-site personnel.
