- Owner: Chevron Texaco
- Project: Petroleum Coke Handling Systems
- Location: El Segundo Refinery, El Segundo, California
- Scope: Feasibilty Study, Engineering, Procurement and Construction
Project Background
Feasibility study, engineering, procurement and construction of improvements to the coke handling system.
R&S prepared a feasibility study that included investigating the coke conveyors, the coke crushing, truck loading and washing, pumping the pit sumps, and removing the coke solids from the recycle cutting water.
At the conclusion of the study R&S was awarded the engineering, procurement and ultimately the construction.
A big concern was designing a layout that could be built during normal coker and refinery operations. R&S was able to construct 90% of the project pre turn-around as planned and completed the last 10% during the turn. Start-up was completed prior to the scheduled completion.
The major equipment and construction involved with this project included:
- Replace the 30’ long turbine sump pumps with submersible sump and modify the coke sump pits to better settle.
- Fabricate and install a second mobile crushing unit as a back-up to the existing mobile crusher.
- Upgrade the existing mobile crusher to match the safety and automation levels of the new crusher.
- Construct two new conveyors and a fully enclosed transfer station including new directionally adjustable chute work, a cyclone dust removal system, and a transfer building.
- Fabricate and install a new 500 ton capacity pant leg load-out hopper. The hopper includes two automatically actuated knife gates for loading the trucks, a 104’ long truck scale, a pulse jet bag house dust collection system, and future support and access for additional conveyors should a new storage facility be required.
- Install a new PLC system that fully automates the hopper level and truck loading and provides feedback to the coke control room and the crane operators from which they can make real time production decisions. The truck driver remains in his cab and is only required to select his final destination to activate the automated loading. The knife gate is activated in such a way as to assure loading to within 200 pounds of maximum load.
- Fabricate and install a new automated truck wash system.
