Calculate shell-and-tube exchanger heat input for PSV fire case
According to API Recommended Practice (RP) 521, 4.4.13.1, “Fire exposure on equipment can result in overpressure due to vapor generation and/or fluid expansion.
Optimize transient plant operations with castable-free fired heater
Fired heaters are designed with castable refractory in various sections of the heater.
Innovations
Alfa Laval has introduced wide-opening design plates in its Packinox heat exchangers.
Selection of cooling water system for gas, petroleum and petrochemical plants located on coastline - Part 1
Cooling water systems play an important role in today’s industry.
Assess remaining life for heater tubes
Refineries and petrochemical plants form some of the major sections of the hydrocarbon industry and consume much of the fuel that is burned in furnaces (heaters and specialty furnaces, such as reformers and crackers) to meet process heating requirements.
Develop reactor internals for optimizing reactor design - Part 2: High-performance mixing chamber
Most hydroprocessing reactors are fixed-bed reactors comprising several catalyst beds that are divided by quench zones containing mixing chambers that introduce a vapor-quenching medium.
Welded plate heat exchangers cut refinery process costs—Part 1
Plate and frame (P&F) heat exchangers were first manufactured 100 yr ago for use in the dairy industry.
Lessons learned from a refinery revamp project
Revamp projects are inherently challenging due to the numerous constraints imposed by existing equipment design and space limitations.
Maintenance and turnaround planning critical to successful ejector vacuum system operation
Steam ejector vacuum systems are generally considered to be reliable and require little maintenance.
Process design consideration for a deep-cut vacuum distillation unit—Part 1
In the recent past, many US refineries have been reconfigured to process heavy opportunistic sour crudes.
