The separation and fractionation systems downstream of the cracking furnaces are based on the progressive separation technology developed by Technip, which allows energy consumption to be minimized thereby
lowering CO2 emissions. This technology is applied in all types of separation sequences mentioned below: Front-end hydrogenation coupled with either front-end deethanizer or front-end depropanizer is available for gas or
liquid crackers. This technology has been already applied and demonstrated in both Technip and Stone & Webster projects. Having provided more front-end hydrogenation designs than any other licensor, Stone & Webster is the world leader. The cumulated capabilities further strengthen Technip’s portfolio in this area.Back-end hydrogenation coupled with front-end demethanizer is applied for either gas or liquid crackers.
This technology has already been applied and demonstrated in Technip’s projects.Technip’s partnership agreement with Wieland for the use of enhanced heat exchangers in Ethylene plants enables energy consumption and CO2 emissions to be even further reduced.The Heat Integrated Rectifier System (HRS) now offered by Technip
has been applied in multiple liquids cracker designs, resulting in the lowest energy consuming plants in the industry. This approach, coupled with Technip’s low pressure C2 Heat Pump option, provides customers the best available technology in the market place
