TOTAL - EBO audit

Customer request

Targeted search for energy savings in petrochemical installations.

Result

CEE audited 8 process units in the EBO (Energie Beheers Overeenkomst- Energy agreement with the Flemish Government) framework. Typical savings implemented :

• Reduced energy consumption of 2 300kW H2 compressors used for hydrogenation, by adjusting compressor capacity to the feed.
• Reduced steam consumption of the H2S strippers by a modified control strategy.
• Higher heat recovery through deeper condensate cooling established by shifting the condensate level.

These interventions led to significant primary energy savings, CO2 emission and costs with a reduced number of mechanical modification of the installations.

Approach

• Indepth study of the installations and operations in collboration with the responsible Process Engineers
• Field research on the installations by means of specific measurements
• Brainstorming with the people in charge of the operations : operations, mechanical and electrical maintenance, engineering, process control and automation.
• Aspen simulation of the modifications with impact estimations
• Live testing on the installations of the modified process parameters 
• Technical and financial study of the measures
• Support in the measurements implementation.
   

These projects have helped Total Raffinaderij Antwerpen to reduce its primary energy consumption by a several % on a yearly basis, to reduce its CO2 footprint and to reduce costs. Nothing but wins !
