  • Maximize reliability in grassroots crude units

    Crude unit operators are far too familiar with a long list of crude unit reliability problems including fouling in heat exchangers and fired heaters, poor desalting, corrosion of piping and equipment, and coking in the vacuum column wash zone. Many millions of dollars have been spent fighting these problems, yet they continue to force unplanned shutdowns with depressing regularity. Revamps must address reliability issues, but project scope is hindered by the limitations of existing ...

  • On budget, on time, offline

    Flawless project execution will not prevent a unit shutdown due to selecting the wrong metallurgy for a challenging crude slate. No matter how well it is fabricated and installed, a shell and tube exchanger with cold, high viscosity vacuum resid on the tube side will have poor heat transfer performance. On-time shipping and installation of a too-small desalter will not prevent crude column overhead corrosion if the centerline velocity is overly optimistic for the design crude. A ...

  • Seven reasons why maintenance managers choose HVTS vs HVOF

    1. Market Recognition - 2. Porosity & Oxides Level - 3. Production Rate - 4. Variable Thickness - 5. Refurbishability - 6. On-site Safety, Quality, and Environment Protection - 7. Project Management.

  • Preparing for a petrochemical plant revamp or technology upgrade

    Petrochemical producers have recently confronted unprecedented volatility in crude oil prices and limits on advantaged feedstock, while the refining and gas sectors remain vigilant to global supply conditions. However, some industry challenges remain unchanged, such as the need to optimize plant operations and cut carbon footprint by reducing the amount of energy required to drive a plant. Equipment nearing the end of its operational life can not only put plants at risk of ...
