Basic Process Control System (BPCS)

Integrity Verification Questionnaire for Basic Process Control System (BPCS)

The objective of Basic Process Control System (BPCS) is to respond to signals from the process and generate output signals which ensure that the operation continues in safe state providing continuous information of the process to the operator. This article discusses the integrity verification tasks associated with BPCS.

quantitative risk assessment

Use of Quantitative Risk Assessment in Chemical Process Industry

Chemical process facilities involve storage and processing of hazardous chemicals, that if released to atmosphere, can have adverse impact on people, assets, environment and thereby affect the reputation of a company. Quantitative Risk Assessment is a well-known technique for evaluating risks of fires, explosions and toxic exposure. this article discusses some fundamentals about QRA.

Computational Fluid Dynamics (CFD)

Success Factors for Computational Fluid Dynamics (CFD) based Fire and Explosion Studies

CFD based explosion studies have several advantages over the usual explosion screening tools that are used in QRA. The main advantage of CFD is its relative accuracy of predicting explosion overpressures in the near and far field. This helps in making more informed decisions about fire or blast protection requirements, which could otherwise lead to unjustified and unreasonable expenditures. This article discusses the benefits of CFD.

Process Containment Integrity Verification Questionnaire

Integrity Verification Questionnaire for Process Containment

The objective of a process containing equipment is to safely contain process fluids (eg. hydrocarbons or other hazardous fluids) under 'reasonably worst case' process conditions, whilst maintaining its integrity and overall risk to as low as reasonably practicable (ALARP). This article discusses questions that need to be addressed to determine the technical and operational integrity of process containment equipment.
