ZAP Engineering crude oil stabilization and treating plant — Delaware Basin, Texas

Onshore Oil & Gas Midstream

Crude Oil Stabilization & Treating Plant

Multidiscipline detailed engineering for a greenfield regional oil treating facility serving Delaware Basin production.

Project Overview

ZAP was engaged by a leading midstream operator to provide multidiscipline detailed engineering for a greenfield regional oil treating facility in Texas. The facility receives high-vapor-pressure crude oil gathered from multiple upstream production batteries and stabilizes it to pipeline specification — achieving target Reid vapor pressure, basic sediment and water, and sulfur content requirements. Stabilized crude is the primary product, with recovered natural gas liquids routed to sales and produced water sent to disposal.

Modular Facility Design & Phased Capacity Growth

The plant is built around modular processing trains, each originally sized for 30,000 barrels per day, with site infrastructure designed for an ultimate four-train, 120,000 barrel-per-day buildout. ZAP subsequently executed a capacity uprate and Phase 2 addition that raised per-train and total throughput, with several systems verified to as much as 172,000 barrels per day. Key equipment includes inlet surge vessels, inlet heaters, low-fouling heat exchangers, three-phase separators, a stabilizer tower, reciprocating overhead compressors, natural gas liquids bullets and pipeline pumps, and a packaged product cooling system — all supported by full balance-of-plant utilities and a manned control room.

High-Paraffin Crude & Wax Management

The defining technical challenge was the high-paraffin crude, containing up to 10 percent wax. This drove excess thermal surface area on oil-service exchangers, regenerable and switchable cooling arrangements to melt and flush deposited paraffin, and carefully controlled minimum wall and film temperatures throughout. ZAP also engineered for a wide inlet temperature range, large slug and flare loads, and cold-weather operability.

Process Safety & Regulatory Compliance

As a process-safety-managed facility, the project required layer-of-protection analysis, safety requirement specifications, and siting review. ZAP’s integrated approach ensured all safety and regulatory requirements were addressed across every phase of the design — delivering a facility built for reliable long-term performance.
