The system was divided into 6 skids with the largest being 8m in length, 3.8m in width and 5m in height. There were four process skids, two utility skids and a distillation tower. Due to height restrictions applicable at the site in Middle East, the distillation tower had to be divided into two separate towers each of 25m height and operating in series. 9 Heat Exchangers of which 1 was a kettle reboiler and 8 were of AES type TEMA-R construction, 4 Vessels, Kerosene Filters, Hot Oil Filters, 7 Pumps and a 2.2 MW Electric Heater. The package was automated with 20 actuated valves, more than 30 transmitters, 3 control panels which was the Heater Panel for the heater, Motor Control Centre for the 7 pump motors and PLC panel for the actuated valves, transmitters in the system. Provision for manual operation at required stages was provided.
The entire package was in hazardous area: Zone2, Gas Group IIA/IIB, T3. The design temperature was 330 ˚C and pressure was 15 barg, which made it a 300# execution. Due to this high temperature, all pressure and flow transmitters were fitted with remote seals, pressure gauges were fitted with diaphragm seals and syphons. All vessels, towers and pipes were insulated as per standards applicable in petrochemical plants. To trip the entire plant in case of fire , LEL detectors had been installed in areas where there were chances of leakage. Also, all control valves had a provision of quick shutoff using solenoids.
