- Dangerous Substances And Explosive Atmospheres Regulations
- UK-based safety regulations (DSEAR) that mandate the control of fire and explosion risks from flammable substances in industrial workplaces. Adherence is vital to protect personnel and equipment by preventing the ignition of hazardous atmospheres.
- Data Acquisition Hardware
- Physical equipment that converts analog signals from industrial sensors into digital data for analysis. It serves as the backbone for monitoring industrial processes and facilitating predictive maintenance.
- Data Acquisition Parameters
- The specific set of variables, such as temperature, pressure, and flow rate, selected for monitoring and logging during a thermal process. Defining these correctly is vital for ensuring accurate performance analysis and enabling effective automated control of the system.
- Data Acquisition Unit
- An electronic device that digitizes physical signals from sensors, such as temperature and pressure probes, for analysis and logging. It is crucial for translating real-world thermal dynamics into actionable digital data for process optimization.
- Data Granularity
- The level of detail and frequency at which energy consumption data is collected. High granularity enables precise diagnostic analysis and the identification of transient operational losses that aggregate metrics might mask.
- Data Integrity Framework
- A structured set of rules and technologies that ensures all process data is complete, consistent, accurate, and secure throughout its lifecycle. In regulated thermal industries, this framework provides the historical proof required to verify that processes remained within safe parameters.
- Data Integrity Guidance
- Regulatory and technical standards ensuring that facility and environmental monitoring data remain complete, accurate, and consistent throughout their lifecycle. Adhering to this guidance is critical for regulatory audits, validation, and quality assurance.
- Data Integrity Standards
- Regulatory and operational frameworks (such as ALCOA+) that ensure process data remains accurate, complete, consistent, and secure throughout its lifecycle. Adhering to these standards is critical for validating thermal processes and passing regulatory audits.
- Data Transfer Protocol
- A standardized set of rules governing how data is formatted and transmitted between different industrial devices and software systems. It ensures seamless interoperability and reliable communication between sensors, PLCs, and centralized energy management platforms.
- Dead Leg Prevention
- The design practice of eliminating stagnant sections in piping systems where fluids can reside, preventing microbial growth that could compromise downstream product safety.

- Decarbonisation Measures
- Strategic actions taken to reduce or eliminate the carbon intensity of industrial processes, such as switching to low-carbon fuels or integrating renewable energy. These measures are critical for achieving long-term climate targets and transitioning to sustainable industrial operations.
- Decentralised Energy Production
- The generation of power or fuels close to the point of consumption, bypassing the reliance on centralized grids and long-distance fuel transport. For industrial process facilities, it improves energy security, minimizes transmission losses, and allows localized utilization of solar and thermal resources.

- Deck Ventilation Systems
- Specialized mechanical air-handling systems designed to continuously circulate air and remove hazardous gases from cargo spaces, particularly on vehicle carriers. They are essential for maintaining safe thermal boundaries, preventing toxic gas accumulation, and controlling humidity to protect sensitive cargo.
- Deep Borehole Disposal
- Deep Borehole Disposal is a high-level radioactive waste management concept that involves placing canisters inside narrow, engineered wells drilled several kilometers into stable crystalline basement rock. This method offers extreme geological isolation, safeguarding biosphere resources from potential contaminant migration.
- Deep Eutectic Solvents
- Ionic solvent mixtures formed by combining hydrogen bond acceptors and donors, resulting in a freezing point much lower than that of either individual constituent. They serve as thermally stable, non-volatile media for gas separation, capture, and electro-chemical processing.
- Demand Controlled Ventilation
- A strategy that adjusts outdoor air intake based on real-time occupancy or pollutant levels, significantly reducing energy costs without compromising air quality standards.
- Demand Response Management
- The practice of adjusting an industrial facility's electricity consumption or thermal processes in response to grid pricing signals or utility incentives. It allows plants to reduce peak energy costs and support grid stability by shifting energy-intensive processes to off-peak periods.
- Demand-Controlled Ventilation
- An HVAC control strategy that dynamically adjusts fresh air ventilation rates based on real-time occupancy indicators like CO2 levels. This approach ensures healthy indoor air quality while preventing the energy waste of over-ventilating unoccupied spaces.
- Demilitarised Zone
- A secure, isolated buffer network that acts as an intermediary interface between an untrusted external network and a highly secure internal operational technology (OT) network. It prevents direct access to critical control systems while allowing secure, authorized data transfer.
