1. Proj. Name：Southern Area Flare Stack PA-7101 Flare Tip System Procurement,

Installation and Commissioning Works

2. Client：CPC Lin-Yuan Petrochemical plant

3. Proj. Period：Apr. 2017∼Jan. 2018

4. Proj. Description：

This project is intended to solve the environmental issue during the massive flare vented to the existing No.4 N.C. elevated flare stack of Lin-Yuan Petrochemical plant CPC, as a result to revamp the old flare tip and its related piping and control system. The newly installed 72”∮ flare tip is capable to handling the max. flaring capacity up to 980,000kg/hr. In the amount of steam supply capacity reaching 63,674kg/hr@6.9 Bar(G), its smokeless operational flow rate can be raised up to the Max. flaring amount of 160,000 kg/hr, and the measuring noise value is less than 80 dBA at the specified noise measurement point Q4N1. In addition to retaining the traditional FFG ignition method, an electronic (manual / automatic) ignition system is added. During the flaring rate varied it can be synchronized to adjust the steam supply in order to saving steam consumption. To achieve automate and optimize smokeless flaring operations, the entire smokeless operation is under DCS automatic control.

5. Major construction item：

◆  Provide brand new 72” NFF-DRAC-HS flare tip (310 SS) x 1 unit

◆  Provide brand new dual ignited flare pilots x 4 sets

◆  Add auto/manual ignition control panel x 1 set

◆  Dismantle the existing 10”∮/60”∮ flare tip & mole seal (including pipeline, operating

platform and climbing ladders)

◆  Hoisting the new 72” flare tip w/pilots and install electronic ignited panel

◆  Replaced the existing 60” mole seal into the new 60”∮ riser pipe (including periphery

pipes, operating platform and renew the climbing ladders)

◆  Add and modify related steam, fuel gas, ignition and drain pipes as well as its insulation

◆  Add new DCS for smokeless steam control system and flare pilot T/T device

◆  Add and modify the material and labor work for existing E & I conduits and cables
