EPC - Cost Advantages of Skid Mounted CA Plants

This presentation incorporates an economic evaluation of the total investment costs

of an EPC Chlor‐Alkali Project considering all necessary steps: PM, Engineering,

Procurement & Logistics, Construction, Mechanical Completion and Start‐Up under

the assessment of two project construction alternatives:

1. Conventional or Site Erected Grass Root Plant

2. Packaged or Skid Mounted Plant

EPC - Cost Advantages of Skid Mounted CA Plants

The Packaged Plant concept in the Chlor‐Alkali Industry has been highly accepted andhas been succesfully introduced by CONVE in both,

Industrialized Countries

Developing Countries

The concept of Skid Mounted Construction was first introduced in the world for a Cl2Plant by CONVE in Guayaquil, Ecuador. This chlor alkali plant, owned today by QUIMPAC,is now successfully in operation since 1996.

The investment estimate values under the following cost break down example are based onlatest projects executed by CONVE. It considers both construction alternatives, showing perresult a 10% higher investment cost for a Conventional Site Mounted Plant than for the SkidMounted alternative. The main factors which cause the higher cost are explained as follows:

THE PACKAGED PLANT ALTERNATIVE LEADS TO SIGNIFICANT COST SAVINGS DURING THE CIVIL CONSTRUCTION PHASE DUE TO FOLLOWING REASONS:

EPC - Cost Advantages of Skid Mounted CA Plants

CONCRETE PEDESTALS ARE PRE‐DESIGNED AND BUILD BEFORE THE MODULES ARE PLACED IN PLACE

DURING EQUIPMENT ERECTION ON SITE, CONCRETE FORMWORK ACTIVITIES SCHEDULE DEPENDS ON STRUCTURAL AND EQUIPMENT / PIPING INSTALLATION CONCLUSION.

THE CIVIL CONSTRUCTION SCHEDULE WILL ALWAYS DEPEND ON THE EQUIPMENT INSTALLATION ACTIVITIES, CONSECUENTLY THE CIVIL WORK ACTIVITIES WILL BE EXTENDED BY ABOUT 5 MONTHS VS. THE PACKAGED
