In recent years, modular engineering and construction has been a subject of increasing interest throughout the process industry. This interest has stemmed from a growing concern over the high costs and protracted schedules encountered in new plant construction, particularly in developing areas ;vhere adverse site conditions and limited skilled labor have accentuated the problem.
AS applied to chemical and petrochemical plants, modular engineering and construction has come to mean a prefabricated and packaged plan't assembly or subassembly that is to be transported and installed at a l-emote operating site.
Most of the emphasis to date has been placed on the various aspects of pack- aging and trznsport, Very little attention has been given to improving the contents of the transport package.

The system can be applied advantageously in all situations, and yields substantial savings regardless of the type of plant, its location, or the

Most importantly, the savings are obtained without sacnifi~ing plant operability or changing the process in any way. Under MPECS, an appreciable
portion of the process plant material and labor is eliminated. Also, an !appreciabl~portion of the field work can be transferred to the controlled, high-productivity environment of fabrication shops.
