Optimize LNG production through contaminant mitigation—Part 2

Wines, T. H., Pall Corp.; Mokhatab, S., Consultant; Trifilieff, O., Pall France

The production of liquefied natural gas (LNG) requires a number of stages to effectively purify the feed gas. These stages are essential to maintain continuous operation and to meet product specifications. Liquid and solid contamination issues are common in many feed gas purification operations and can cause severe problems with equipment fouling, leading to additional expenses in maintenance and equipment repair, reduced production capacity and even unscheduled shutdowns.

Use your data to its full potential to prevent outages

Creef, B., HIMA Americas, Inc.

In a process plant, the safety system is responsible for the protection of personnel, resources and the environment, by taking the plant to a safe state in the event of a fault. However, is the system capable of contributing more to the plant’s uptime and profitability?

Engineering Case Histories—Case 99: Pooling knowledge and experience builds personal and team success

With the help of an excellent mentor, I became adept at analyzing equipment and structures at the start of my career, using analytical techniques.

Migrating from Fortran to ISA S-88

Ford, J., Kolluri, T., Bozeman, J., MAVERICK Technologies

A major refiner operates two catalytic reforming units for gasoline octane improvement and aromatics production in Texas. In each of these units, five reactors filled with catalyst are operated continuously in series to reform paraffinic hydrocarbons in the presence of hydrogen (H2). During this process, some byproduct coke is unavoidably produced and deposits on the catalyst, which leads to gradual catalyst deactivation.
