Pipelines, Fractionation and Liquefaction, Permico Midstream Partners

• Location: Louisiana, USA

• Builder: Permico Midstream partners / Technip

• Status: Restarted 2025

• Role: Interface Managame and Vendor Alignment

The Permico Midstream Partners project developed an integrated natural gas liquids (NGL) system, transporting Y-grade feedstock from West Texas to export markets via pipelines, fractionation, liquefaction, and marine offloading. The system was designed in phases to scale with demand.

Pipelines and Pump Stations

• Compañero Pipeline: 870 km (540 miles), 20-inch diameter. Transports Y-grade feedstock from West Texas to Corpus Christi fractionation plant. Includes 5 pumping/pigging stations.

• Simpático Pipeline: 600 km (373 miles), 16-inch diameter. Carries high-purity products to East Texas Gas Hub near Mont Belvieu. Includes 2 pumping/pigging stations.

• Typical Costs: $700 - 900 Million

Fractionation

The central fractionation plant in Nueces County processed Y-grade feedstock into high-purity NGL products (propane, butane, ethane, etc.). High-pressure compression was used to transfer the separated liquids to sphere storage tanks for secure, high-volume containment. Typical Costs: $550 - 750 Million

Liquefaction

A dedicated liquefaction facility converted the purity products into liquefied form using gas chillers and refrigerant compressors. The liquefied products were stored in low-pressure (LP) tanks, with boil-off gas (BOG) managed through vapor recovery and compression systems. Typical Costs: $200 - 300 Million

Offloading

An LPG loading wharf was equipped with two sets of five loading arms to transfer liquefied purity products to LNG carriers for international export. The design supported efficient loading operations, with typical vessel capacities of 125,000 barrels and provisions for temperature maintenance and vapor recovery during transfer. Typical Costs: $100 - 150 Million
