Public LEILAC-2 Pre-FEED Summary Report

This report initially provides a high-level overview of the pre-FEED phase results, covering the background, risks, project rationale, design basis, engineering, conclusions, and next steps.

The major conclusions is that LEILAC2 has been comprehensively reviewed, and approved by the project’s General Assembly. The project will now enter the next stage of development – Front End Engineering Design (FEED) phase. During the FEED phase, the de-risking focussed approach will continue with the aim of reducing all technical risks to ‘low’, and of further developing and optimising the engineering design, along with its integration into the HeidelbergCement cement plant at Hannover, Germany.


The site development and procurement plans will be produced, and a ±15% cost estimate generated for approval. This will underpin the Final Investment Decision regarding the build of the plant.

The LEILAC project (Low Emissions Intensity Lime And Cement) is

developing a pilot to test Calix’s Direct Separation Technology. The pilot and its equipment will be built and integrated into the HeidelbergCement cement plant at Lixhe, Belgium.

A Front End Engineering and Design (FEED) study was developed to provide a final design and cost for an optimal configuration of the pilot plant, completed to a point such that no material variations would be required. As such, this FEED report summarises the main engineering actions of this critical development phase of the project. It covers the period from October 2016 to the Final Investment Decision (FID) in June 2017.

The LEILAC project (Low Emissions Intensity Lime And Cement) will

successfully pilot a breakthrough technology that aims to replace an existing part of the cement and lime making process, and enable the capture of unavoidable process carbon dioxide (CO2) emissions without significant energy penalty (just compression) at comparable capital costs to conventional emitting equipment.

The LEILAC project is primarily based on the development and testing of a suitably sized pilot plant to validate the technology and facilitate scale up. Constructed next to the HeidelbergCement’s plant at Lixhe, Belgium, the pilot will function in a realistic operating environment. This Pre-FEED summary represents the evolution, achievements and intentions of this initial phase of the project. This report summarises the main research, development and engineering actions contributing to the first project stage-gate. It covers the period from the commencement of the project in January 2016 to the go/no go decision in October 2016.
