This document specifies the requirements for materials, design and installation of the insulation of refrigerated liquefied gas (RLG) storage tank systems. RLG storage tank systems store liquefied gas with a low boiling point, i.e. below normal ambient temperature. The concept of storing such products in liquid form and in non-pressurized tanks therefore depends on the combination of latent heat of vaporization and thermal insulation. Consequently, thermal insulation for RLG storage tank systems is not an ancillary part of the containment system (as for most ambient atmospheric hydrocarbon tanks) but it is an essential component and the storage tank system cannot operate without a properly designed, installed and maintained insulation system. The main functions of the insulation in RLG storage tank systems are: - to maintain the boil off due to heat in-leak at or below the specified limits; - to limit the thermal loading of the outer tank components, so to prevent both their sudden damage and premature ageing (e.g. due to external condensation and ice formation); - to prevent damage by frost heave of the foundation/soil beneath the tank base slab (in combination with the slab heating system for tanks resting at grade); - to minimize condensation and icing on the outer surfaces of the tank. A wide range of insulation materials is available. However, the material properties differ greatly amongst the various generically different materials and also within the same generic group of materials. Therefore, within the scope of this document, only general guidance on selection of materials is given. NOTE For general guidance on selection of materials, see Annex A. This document deals with the design and manufacture of site built, vertical, cylindrical, flat-bottomed tank systems for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and -196 °C. refrigerated, liquefied gases with operating temperatures between 0 °C and -196 °C.

This document specifies the conditions for the determination of uniaxial tensile properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at elevated temperature in air, vacuum or inert gas atmospheres. This document is specific to the tubular geometries because fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This document provides information on the axial tensile properties and stress-strain response in temperature, such as axial tensile strength, axial tensile strain at failure and elastic constants. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components. This document addresses, but is not restricted to, various suggested test piece fabrication methods. It applies primarily to all ceramic matrix composite tubes with a continuous fibrous-reinforcement: unidirectional (1D, filament winding and tape lay-up), bidirectional (2D braid and weave) and multi-directional (xD, with x > 2), tested along the tube axis.

 

This document specifies requirements and test methods of valve-actuator assemblies in individual zone control of water-based HVAC applications. Control valves of nominal diameter larger than DN50 are currently not covered by this document. Within the scope are pressure independent and pressure dependent control valve-actuator assemblies of relevant categories: 2-port, 3-port and 6-port valves (if they incorporate a control valve function). Where a certain control loop as a combination of controller and valve-actuator assembly was assessed under EN 15500-1:2017, this European Standard allows the assessment of the performance of combinations of that controller with different valve-actuator assemblies. The tests in this document ensure that valve/actuator assemblies, as components of control loops, can be replaced with products that provide comparable or better performance. In hydronic system, valve-actuator assembly is a component of control loop that controls water flow rate according to the application control demand. The common Formula (1) describing the flow rate where whole hydronic system itself has an influence on actual flow rate as differential pressure across control valve-actuator assembly typically varies during operation.

This International Standard specifies ways in which rare earths can be traced as they move through the supply chain between the separated products to rare earth permanent magnets, or otherwise further processed. This standard complements ISO 23664. The documented traceability information will assist purchasers, suppliers, and users of rare earth permanent magnets to identify parties in the supply chain who have processed a given shipment of rare earth material, the location of that rare earth material as it passes between supply chain nodes. Supply chain actors and end users can use this information to check the validity of any claims made on the rare earth permanent magnets concerning sustainability, environmental impact, or recycled material content.

 

This document specifies methods for measuring and evaluating the performance of CO2 capture connected to a CO2 intensive plant, and which separate CO2 from the CO2 intensive plant exhaust gas in preparation for subsequent transportation and geological storage. In particular, it provides a common methodology to calculate key performance indicators for the CO2 capture plant, requiring the definition of the boundaries of a typical system and the measurements of parameters needed to determine the KPIs. This document covers the CO2 capture plant capturing CO2 from CO2 containing exhaust gas” connected to CO2 intensive plants. The connection of a CO2-capture plant to a CO2-intensive plant is anticipated to have negligible impact on the product quality or the quantities produced by the CO2-intensive plant. This is in contrast with the integration of CO2-capture plants with power plants which usually results in a reduction of the power plant output. For the CO2-intensive industry it is important that product quality remains the same after connection of the CO2-capture plant, in order for the industry to continue to meet customer requirements. The CO2 capture technologies covered by this document are able to operate without interfering with the operations of the CO2 intensive plant. Frequently used CO2 capture technologies are chemical absorption (e.g., liquid amine) and solid adsorption (e.g., Pressure Swing Adsorption (PSA), Temperature Swing Adsorption (TSA)). Other CO2 capture concepts are membranes, cryogenic and other capture technologies. The CO2 capture plant can be installed for treatment of the full volume of exhaust gas from the CO2 intensive plant or a fraction of the total (i.e. a slipstream). Captured CO2 is then conditioned, e.g. dried and compressed or liquefied, as determined by the conditions needed for transportation and storage. The transportation can be either through a pipeline or through an intermediate storage facility waiting for shipment; either by tanker car, train, or ship. The KPIs considered in this document are the following: The calculations are based on measurements at the boundary of the CO2 capture plant, particularly of energy and other utilities consumption. The system includes interfaces between the CO2 capture plant and the CO2 intensive plant. This document includes the following items: This document does not provide guidelines for benchmarking, comparing, or assessing KPIs of different technologies or different CO2 capture projects.
