Kryolize is a software tool for sizing the minimum discharge area of a safety protection device, against overpressure. Based on international (ISO), European (EN) and American (API) standards, Kryolize allows calculation and sizing of safety valves for cryogenic systems and is a novel tool that will help engineers with a uniform approach in the sizing of safety valves for cryogenics applications.
