← Back to Tank Vapor Recovery System Upgrade

Overview

Cannon was selected to help increase the current capacity, safety, and reliability of the CAHN 3 tank vapor recovery (TVR) system. The existing TVR system was at risk for potential releases of hydrocarbon vapors to the atmosphere, which can trigger a Notice of Violation (NOV) from the San Joaquin Valley Air Pollution Control District (SJVAPCD) and result in hazardous working conditions for onsite personnel. There were also safety and reliability concerns with operating the existing vapor recovery units (VRU). Upgrading the TVR system required stainless steel replacement piping to the VRUs; rerouting the discharge piping from the VRUs; new VRU compressor packages; and additional instrumentation and automation to better monitor and control the TVR system. The project scope included survey/scanning of existing site conditions, piping system design, equipment foundation design, pipe support analysis and design, electrical system upgrade design, automation design, and preparation of construction drawings and documents.

The project was completed in two stages. The first stage of construction focused on removing “bottlenecks” from the existing TVR system. Existing piping from the T-106/107 Wash Tanks, the V-101 Production Inlet Separator, and the main collection header, to the skid limits (suction scrubbers) of the K-301/302 VRUs were replaced with stainless steel piping sized for current and proposed system flow rates. Tie-ins were designed for the new VRUs. The construction for the first stage occurred during a planned plant outage, so the design allowed for a quick turnaround during execution. The second stage of construction involved installation and start-up of the new compressors, including piping completion, skid foundation installation, electrical design, and automation design to incorporate the TVR system and VRU instruments into the plant PLC.
