ENVIA Energy

First product achieved at commercial reference site.

ENVIA Energy's Oklahoma City GTL project is located adjacent to Waste Management's East Oak landfill site and will use a combination of landfill gas and natural gas as feedstock. ENVIA Energy is a joint venture that was announced in March 2014 to produce renewable fuels and chemicals from biogas and natural gas using GTL.

The plant deploys Velocys' full-scale commercial Fischer-Tropsch (FT) reactors, the manufacture of which was completed in 2015. On-site loading of Velocys' catalyst into the Fischer-Tropsch reactors was completed in the autumn of 2016 by Velocys with support from its internationally-recognised partner Mourik.

During the first half of 2016, having made additional funding provision to ENVIA, Velocys sought and gained greater operational management involvement and shareholder influence in the project.

Since that time, Velocys has been supporting the EPC contractor, Ventech, in leading the planning for and execution of the commissioning, start-up and operation of the plant. The Company has provided, under contract, an operability review, operating procedures and commissioning management.

Under a secondment agreement with ENVIA, Velocys’ team of experienced GTL operations managers, operators and engineers have been on site in Oklahoma City since their deployment began in July 2016. This Velocys operations team, which is serving under the ENVIA Plant Manager, has brought essential support to the ENVIA team through commissioning, start-up and early stage operations, and will remain on site until the permanent operations team is fully phased in over the coming months. The Velocys team brings a wealth of operational GTL plant expertise including commissioning and plant performance optimisation, drawing on experience gained at a number of large scale commercial GTL projects as well as from the Velocys pilot plant.

The team has made extensive and detailed preparations during the pre-commissioning and commissioning phases; operating manuals and procedures were completed and robust commissioning and start-up plans were set in place. In line with best practice, the commissioning plan ensures that each process system in sequence is working robustly, safely, and within specification, in order to best assure a successful, safe and uneventful plant start up.

First Fischer-Tropsch product was produced at the plant in February 2017. These products are fractionated on site to produce premium wax, diesel and naphtha. The fuels produced at the plant are expected to qualify under the Renewable Fuels Standard (RFS) and generate tradeable credits in the form of Renewable Identification Numbers (RINs).

The operations team will now focus on ramping up production to full capacity and preparing for the performance test run on the plant.

Evaluation continues, with our partners, on future ENVIA projects using learnings from the Oklahoma City project.
