Hydraulic Decoking Systems AutoShift™ Cutting Tool
The AutoShift combination decoking tool makes remote drum decoking feasible by removing the operator from the cutting deck. Boring and cutting mode shifting is accomplished automatically and safely within the drum by water pressurization and depressurization.
- Applications:
Petroleum Production and Refining, Decoking - Industries:
Heavy Oil and Upgrading, Delayed Coking
Features and Benefits
The AutoShift combination decoking tool provides numerous benefits to hydraulic decoking operations:
- Improved Operator Safety – Remote operation eliminates operator exposure to high-pressure water, steam eruptions, H2S vapors and mechanical hazards
- Greater System Automation – Automatic shifting coupled with computerized controls and instrumentation enables total process automation
- Reduced Cycle Times – Automatic shifting within the drum saves 30 minutes or more per cycle
- Improved Efficiency – The decoked vessel returns to service more quickly and safely
- Easier Maintenance – AutoShift features a self-cleaning design that flushes coke fines from the shifting mechanism and jet ports
- Shifting Flexibility – “Stuck” tools can be freed up quickly within the drum by automatically shifting between boring and cutting modes
- Manual Shift Feature – If necessary, AutoShift can quickly and easily shift modes as with traditional combination cutting tools
- Retrofit Cartridge Assembly – Existing Flowserve (i.e., Worthington, Pacific) and non-Flowserve hydraulic decoking systems can upgrade to AutoShift technology
