Case Study

Glycol Dehydration Unit (GDU) Fuel Gas Reliability Project

Glycol Dehydration Unit (GDU) Fuel Gas Reliability Project

The fuel gas system at a large refinery had experienced numerous problems with leakage and fouling with sludge. A reliability team of experts identified water as a main precursor of corrosion and sludge formation throughout the fuel gas system. It was determined that a Glycol Dehydration Unit (GDU) needed to be installed to treat the fuel gas supplied to all plant-wide users to improve the fuel gas reliability and to maintain the integrity of the existing fuel gas system.

Flare Header & Knock Out Drum Redesign

Flare Header & Knock Out Drum Redesign

A refinery-wide flare study revealed a substantial deficiency in the capacity of a knock out drum in one of our client’s units. Without sufficient capacity or retention time, there was a threat of liquids being sent to the flare tip or vapors being routed to the facility's slop line in the event of system over-pressurization. The existing knock out drum was located underground, which also reduced the ability to inspect and maintain the system. Any modification needed to be completed within an existing turnaround schedule.

New Hydrogen (H2) Unit Offsites Installation

New Hydrogen (H2) Unit Offsites Installation

A refinery owner required additional hydrogen to comply with federal specifications to process low sulfur diesel fuel. The refinery owner and a gas supplier contracted to jointly own and operate a hydrogen plant at the refinery. The hydrogen plant needed to be designed and constructed around the refinery's existing conditions to supply the additional hydrogen needed to process the diesel fuel and fulfill federal regulations.

Installation of New Sour Water Stripper (SWS) Reboiler System

Installation of New Sour Water Stripper (SWS) Reboiler System

A large refinery client was in need of a team with the capabilities to execute a fast track project to debottleneck the refinery during gasoline season without compromising safety. The project involved interconnecting piping which included heavy vacuum gas oil (HVGO) from the crude unit to the new sour water stripper (SWS) reboiler in the refinery’s sulfur recovery unit (SRU).

T-1000 Tank Farm Upgrade

T-1000 Tank Farm Upgrade

A refinery client needed to load and unload an increasing volume of high paraffin content crude oil from their terminal to meet demand for the product. This required a design to incorporate new infrastructure into their existing rail system, tank farm and dock infrastructure to enable the efficient loading and unloading of this crude oil between transportation and storage.

Isomerization Unit Upgrade

Isomerization Unit Upgrade

A natural gas liquids (NGL) client needed to upgrade their existing isomerization unit and increase its capacity from 6,000 to 9,000 bpd. This project needed to be divided into two phases and fast tracked to accommodate an upcoming turnaround and a time sensitive completion incentive. This project consisted of an upgrade to the Butamer feed pumps, Hydrogen Cleanup and Recycle, and iC4 Recovery.

Pipe Bridge Project

Pipe Bridge Project

A refinery client needed design support to reroute eighteen (18) pipe runs that were laid underneath 127th Street. They needed to find a solution that would permit them to maintain and inspect the piping in accordance with API 570.

Natural Gas Storage Facility Sulfur Removal System

Natural Gas Storage Facility Sulfur Removal System

A natural gas storage facility client had an existing Stretford Processing System for sulfur recovery at its storage facility that was aging and requiring extensive repairs and maintenance in ever more regular intervals. The client was looking to replace this system with one that would still remove the hydrogen sulfide from the natural gas before entering the pipeline while improving reliability and decreasing operational complexity.

Natural Gas Storage Facility Compressor Replacement

Natural Gas Storage Facility Compressor Replacement

A major supplier of natural gas needed to install a 5,000HP natural gas compressor and required assistance in the design, layout and implementation of the project. To our client, it was very important that they were closely consulted with and that they worked alongside our design team in the development of design and bid packages.

Cooling Tower Replacement

Cooling Tower Replacement

A large refinery client had a Cooling Water Tower (CWT) that was at end of life. The CWT needed to be rebuilt to maintain its original performance and ensure long-term reliability. Valdes guided the client in exploring their options, including the rental of a temporary tower or running with existing towers in operation with strategically-placed piping. The second option was ultimately selected.

Reformer Unit Turnaround Equipment Replacement

Reformer Unit Turnaround Equipment Replacement

A large refinery client needed various equipment replaced sooner than expected due to corrosion. For each of the replacement projects, there was an increasing risk of reaching end of asset life-cycle prior to the planned replacement scheduled. The replacements were originally contemplated for a future turnaround, however, it was apparent that the work needed to execute the replacements would need to be ready for an upcoming turnaround schedule.
