This publication provides safety and operating guidelines to address the hazards associated with the operation of small scale hydrogen production plants and with the siting next to a liquid fuelling station. This document references other related documents and adapt the guidelines of large-scale HYCO facilities to these small scale operations.

We recognise the ambition to restrict PFAS to protect human health and the environment for future generations. In parallel, the PFAS restriction as defined today will significantly impact all aspects of gas industry. This document describes 5 main uses that will be impacted by the PFAS restriction proposal.

This publication covers cryogenic reciprocating pumps and pump installations for hydrogen and LNG service.

High Temperature Hydrogen Attack (HTHA) is a mechanism that can significantly weaken and damage a variety of steel materials that are used in the construction of hydrogen plants, including carbon steel and various low alloy steels. Recently HTHA limits have been changed. This publication provides guidance, heuristics, and some examples of methodologies for the review of existing HYCO plant assets to determine their potential for HTHA-initiated cumulative damage. It will also provide guidelines for risk categorisation, inspection strategies, and recommendations on risk mitigation.

The purpose of this publication is to provide a summary of operating risks, recommendations and guidelines for the safe design and operations of various hydrogen (H2), carbon monoxide (CO) and syngas (H2 & CO) production facilities including carbon (CO2) capture, sometimes known as HyCO plants.

This publication is intended to provide general guidelines for the purification, compression and drying of acetylene. It includes recommendations for operational and maintenance safe practices to mitigate potential acetylene decomposition and other hazards related to the purification, compression and drying of acetylene.

Companies supplying acetylene will often have more than one grade or purity of acetylene. This publication provides specification requirements for gaseous acetylene. The user of the acetylene needs to decide what grade, purity or impurities are appropriate to their need. This publication does not attempt to recommend or establish end usage designations for specific types or grades of products. It is suggested that users requiring this kind of information contact individual acetylene gas suppliers.

This publication has been developed to give guidance on mechanical integrity (MI) of acetylene generator systems. A MI programme is intended to ensure that equipment does not fail in a way that causes or enhances a catastrophic release of highly hazardous chemicals.

This publication applies to HYCO plants and provides design and safeguards requirements of utility and instrument gas systems. It identifies the potential hazards resulting from the connections between gases, instrument gases, and the process.

This publication is intended to provide general guidelines for safe operation of acetylene generator systems. It is limited to acetylene generation systems using calcium carbide added to water, known as wet generation. The scope includes the carbide supply from receipt at site to entry into the generator, the generation of acetylene to the pipe leaving the generator, the control of temperature via water supply into the generator, the control of level via the discharge of lime out of the generator and gasholders and buffers. The scope does not include water utilities, lime handling after discharge from the generator, nor response to emergency or abnormal situations.
