Heat Transfer
Optimal gas analysis decisions improve ethylene plant operation
One of the most common and important building blocks in the petrochemical industry is ethylene, constituting a huge and fast-growing worldwide industry. Ethylene is an intermediate chemical used to manufacture many commercial products—approximately 200 MMt will be produced in 2020.
Case study: Heat exchanger tube rupture and its impact on metal embrittlement
Process engineers strive to recover as much energy as is practically possible from the available process and utility streams within the constraint of the plant. To achieve this goal, traditional—and sometimes non-traditional—methods are utilized. In a steam cracker, light olefins are considered the highest-value products, and utilizing “cold energy,”
Heat Transfer: Designing electric process heater systems for catalytic regeneration
Achieving effective catalyst regeneration requires a process that produces a very high level of heat in a very efficient manner. Over the years, several different approaches have been taken to create this required heat. Traditional steam has been a popular choice, as has heated transfer media. However, these methods have limitations.
Rethink fired heater design for emissions
As environmental regulations are becoming more stringent on reduced nitrogen oxide and carbon monoxide emissions, burner designs are changing to meet revised regulations. The heater design must complement the chosen burner for optimal performance. Although design duty is considered to be the main focus of the heater design, the range of heater operation and its impact on heater safety and emissions needs are often neglected.
