Flare and Safety Pressure Relief System Services Our Services PROCESS provides a full range of services relative to the sizing, verification, and modeling of Flare Systems and Pressure Safety Relief Valves (PSVs or PSRVs, Rupture Disks, and Conservation Vents) including the following: • Generate all calculations and associated documentation for the sizing and selection of PSVs per API and/or ASME Code requirements for new or existing installations. This also includes: • Identification of and calculations for all credible scenarios, not just the controlling scenario • Physical properties generated by CHEMCAD process simulation models for each stream • Performing pressure drop calculations for both inlet and outlet piping. • Flare stack or vent stack sizing (height, diameter, tip configurations, etc.) to fall within API Code requirements. Flare manufacturers are also consulted to ensure the best available technology is included in the design. Knockout drums and blowdown systems are also designed and sized for each particular installation. • Generate all documentation needed to meet OSHA requirements and any specific company requirements • Generate required PSV specifications (spec sheets) • Construct a flare or vent header pressure drop simulation model in CHEMCAD or FlareNet, including both inlet and outlet PSV piping configurations • Perform flare or vent header pressure drop evaluations for specific PSV combinations associated with global relief scenarios. Simson s51 reparatur pdf. These global scenrios are developed by working in conjunction with the client's plant staff and PROCESS often spends additional time on-site to collect any missing information that may be needed. Our Experience PROCESS has performed relief valve sizing calculations for thousands of relief devices. These include pressure safety valves of all types, traditional spring loaded relief valves, conservation vents, and rupture disks. All of these systems are designed to protect a process by safely relieving excess pressure under abnormal operating conditions. It is critical that they be sized appropriately to protect both personnel and physical assets. Many such relief devices are simple stand alone units venting to the atmosphere, while others are highly specialized devices designed to handle two-phase flow and tie into a complex process wide vapor collection or flare header system. Typically we are asked to either provide specific relief valve sizing/evaluation or we are asked to perform an entire flare header system evaluation with many relief devices connected to it.

Our Methodology In general, PROCESS follows methodology set forth in the American Petroleum Institute (API) 520, 521, and 2000 guidelines. When performing an evaluation to determine if adequate relieving systems are in place for an existing system and if the flare header is adequately designed, the following steps are typically involved. Relief Device Evaluation: • Collect information on the existing system (PSV data, P &IDs, protected equipment information, flare header isometrics, inlet/outlet line sizes, etc.). • Work with the client's technical staff to develop the credible relief scenarios, both for individual pieces of equipment and especially for those effecting entire units or sections of the plant (blocked flow, external pool fire, loss of cooling, loss of power, etc.). • Build a simulation of the process (if needed) to ensure accurate process conditions and stream compositions are available for all relieving scenarios.
