Considerations for revamping shell-and-tube heat exchangers
Revamp projects are complex in nature, and demand a great deal of resources for successful completion.
Revamp fired heaters with a common air-preheating system to increase capacity
In any process plant, fired heaters are generally considered to be one of the most optimally designed pieces of equipment.
Alfa Laval awarded $10.6 MM energy-efficiency order in China
LUND, Sweden — Alfa Laval—a heat transfer, centrifugal separation and fluid handling company—has won an order to supply compact heat exchangers to a refinery in China.
Modified revamp process to reduce energy use in an SDA unit
Solvent deasphalting (SDA) is emerging as a low-cost, bottom-of-the-barrel upgrading process to recover valuable oil from short residue. This oil can either be further processed to make lube-oil-based stocks or cracked in secondary processing units.
Alfa Laval to supply heat exchangers to China refinery
LUND, Sweden -- Alfa Laval has won an order to supply compact heat exchangers to a refinery in China. The order has a value of approximately SEK 210 MM. It is booked in the Welded Heat Exchangers unit of the Energy Division, with deliveries scheduled for 2018.
Improve energy efficiency with enhanced bundles in tubular heat exchangers
From 2008 to date, 45 twisted tube heat exchangers and bundles have been installed at BAYERNOIL refineries in different units and services, allowing higher heat recovery and contributing to BAYERNOIL’s energy targets.
Recommended practices for fired process heater instrumentation and control
Fired process heaters are one of the most critical pieces of equipment within many refinery and petrochemical facilities. Proper instrumentation and control of the equipment has direct bearing on the successful operation of the process, as well as on overall facility process safety.
A deeper examination of thermal expansion issues in process equipment and piping
Piping and process equipment that operate at high temperatures experience thermal expansion. If free thermal expansion is restrained, mechanical stresses are created within the component.
IR camera technology provides new perspective on furnace inspection routines
A few years ago, managers at a US-based oil refinery called in an expert to inspect their oil furnaces with an infrared (IR) camera.
Key design considerations for vacuum process condensers
The crude oil refining and petrochemical industries make extensive use of condensers that operate under vacuum (i.e., below atmospheric pressure). Distillation is the most common process using these condensers, either as a process precondenser ahead of an ejector system, or as an intercondenser within an ejector system.
