Use this record when

The decision this case can inform

Assess capture capacity, actual utilization and energy demand as separate measures.

Evidence scope

Producer-reported evidence. This record establishes a milestone, not quantified operating savings.

Source-supported facts

What the public record actually establishes

2 sourced points
  1. F1

    Additional absorption equipment and oxygen-removal equipment were added.

  2. F2

    The operator reports capacity increasing from 900 kg/day to up to 2 t/day.

Structured interpretation

Facts and reported results are kept separate from the lesson a plant may choose to test.

01

Operating context

The operator expanded a cement-flue-gas capture pilot.

02

Intervention or finding

Additional absorption equipment and oxygen-removal equipment were added.

03

Documented result

The operator reports capacity increasing from 900 kg/day to up to 2 t/day.

04

Plant interpretation

Assess capture capacity, actual utilization and energy demand as separate measures.

05

Transfer boundary

Pilot capacity is not annual captured mass or whole-plant capture. Availability and energy demand remain necessary context.

Before applying the lesson

Questions to verify at your plant

These are decision checks, not operating instructions. Resolve them through local risk assessment, technical review, and authorization.

  1. 01

    Obtain metered captured mass, capture-stream boundary, solvent use and heat requirement.

  2. 02

    What equipment, materials and operating conditions differ at your plant?

  3. 03

    What baseline and follow-up evidence would establish whether this change works locally?
