GE Technology Helps Refinery Cut Water Use, Emissions
Compañia Española de Petróleos (CEPSA), a Spanish petrochemical companies, has adoptedGeneral Electricgas turbinetechnologyat its Gibraltar-San Roque refinery to meet environmentalemissionsrestrictions without reducingefficiencyor increasing operational cost.
Developed by GE's Power Generation Services business, the fuel-flexible high hydrogen fuel DLN1 technology increased the gas turbine's efficiency by enabling it to use recycled refinery fuel gas (RFG) without needing additional water to generate power.
Refinery gases are used as fuel for CEPSA's internal processes with excess gas flared. GE's turbine configuration recaptures and reduces waste gas that otherwise must be flared or burned off. The gas, known as RFG, is a typical byproduct of the refining process and contains hydrogen and hydrocarbons, which contribute to greenhouse gases.
This is the first time a refinery has adopted a process that uses RFG to power turbines for generating electricity without using water and reflects the fuel flexibility of GE's 6B DLN1 heavy-duty gas turbine design that blends startup fuel (natural gas) with RFG fuel. The flexible fuel configuration caps GE's three-year research and development effort.
