Keystone’s scope included engineering and design services to construct a 450 MMSCFD gas treating and compressor station near Encinal, TX. The facility receives and conditions produced gas from incoming pipelines. The facility consisted of incoming pipeline receivers, inlet slug catchers, an amine unit, glycol unity, compression, produced liquids handling system, fuel gas system, instrument air system, start air receiver, Control/MCC Building, PLC Control System, and Vent System.

Project to upgrade and increase compression at a compressor station in Cameron Parish, LA to satisfy new commercial agreements to increase natural gas delivery quantity and pressure to an existing customer. The compressor station has been bypassed since being damaged by a recent hurricane. The upgrade demolished the existing equipment and piping from the station and installed the new equipment. The upgrade is to install a Solar Titan 130 Turbine Compressor and supporting processing/measurement equipment to handle the 500 MMSCFD of pipeline quality natural gas. The project installed the Titan 130 and ancillary equipment on a reengineered and improved existing elevated deck. The Titan 130 was housed in a customized prefabricated metal building. Other facility critical equipment was installed on engineered structures above flood plain elevation. The new compressor increased pipeline flow to 500 MMSCFD for a delivery pressure of 900 PSI. The project also installed a pipeline manifold to bypass the station and reverse pipeline flow in case of customer facility shutdown.

Keystone provided project management, engineering, design, and procurement support services for the detailed engineering design of three laterals as part of the larger pipeline system connecting Orla to Mont Beliveau. The client installed approximately 132 miles of 24” ANSI 600# pipeline to transport Y-Grade or Raw NGL mix from Orla, Texas to High Plains, Texas. Additionally, a 30-mile lateral receiving Y-Grade NGL from ARM and transporting to the Shin Oak pipeline. The scope of work included a Coriolis Meter, pig traps, and multiple MLV’s.

Keystone provided project management, engineering, and design services for the expansion of a pipeline terminal, including the installation of a new 80,000 barrel tank and additional rail offload for ethanol storage, as well as a new eight inch transfer line. The existing ethanol rail offload was expanded to add spaces for another 20 cars, including the all rail infrastructure with containment, safety equipment, pump capacity upgrades and capability to provide product to an existing tank, the new 80,000 barrel tank, and provide flow to the new transfer line.

Additionally, a second facility takes deliveries from the pipeline and includes storage for all of the products (gasoline, diesel and ethanol, etc.). This facility was given the accommodations to fill transport trucks for delivery to customers using two separate additives, which provides the required lubricity additive for the ULSD and uses a VRU as the required vapor control unit for the truck loading area.

Scope of Work also included: composing performance specifications and assisting with procurement of railcar expansion, storage tank and electrical switchgear/MCC, 4-bay truck loading station, four new buildings, 6 new tanks, VRU system for the terminal/truck loading, fire and gas safety system for the terminal, ethanol blend skid, evaluating utility systems, modifying containment and drainage systems, and specifying equipment including: railcar offload pumps, transfer pumps, manifolds, and meters.

Keystone provided multi-disciplined engineering and design services to install all piping, pig traps, meters, and infield pipelines associated with a greenfield 200 MMSCFD gas plant. The project scope of work included piping, foundations, controls, and power interconnect associated with pig receivers and ultrasonic meter skids on incoming 12” and 24” gas lines. Additionally, the scope included a Coriolis meter skid on 16” export NGL line, 16” and 20” residue gas export lines, and pig receiver at remote surface interconnect site.

The pipeline scope included crossing and code calculations, material selection, hydraulics, and interface with the surveyor to develop alignment sheets associated with 12” and 24” incoming gas lines, and 16” and 20” residue gas export pipelines between the new Cryo plant and nearby surface
sites.

Keystone provided project management, engineering, and design services at a greenfield and existing site in South Carolina for the installation of additional compressors. The project goal included increasing the overall pipeline capacity.

The brownfield compressor station expansion added new compressors to increase capacity from 150 MMSCFD to 300 MMSCFD. The scope of work included the installation of new separation vessels, coolers, and fuel gas coalescers. The greenfield site included installing a Solar Saturn turbine with centrifugal compressors for 175 MMSCFD with separation vessels, compression coolers, and fuel gas coalescers. Additionally, Keystone provided procurement, bidding, and permitting support services for this project.

Keystone provided project management, engineering, and design services for the detailed engineering design of the Orla Gas Gathering System located in West Texas and New Mexico.
