Avoid fired heater coking

For many refiners, heater coking in Crude and Vacuum Distillation Units (CDU/VDUs) is a common occurrence. Many units around the world are shut down every two years, every year, or even every six months to deal with chronic heater coking. However, with the right design features driven by a solid understanding of heater coking mechanisms, fired heater run length can be extended beyond five years, even with relatively challenging crudes. The two primary drivers of heater tube ...

Condensate is crude

Ultra-light crudes and condensates are here to stay. These streams have flooded the market in recent years, and many of them are deeply discounted against reference crudes. Refiners have been processing increasing percentages of this light material through their Crude Distillation Units (CDUs) up against unit naphtha handling limits. On the surface, processing condensate and other ultra-light crudes with high API gravity and low sulfur should be easy. In reality, many refiners ...

Designing deepcut vacuum units that really work

Every barrel of vacuum gas oil (VGO) you can save from being reduced to coke in the delayed coker unit is a barrel more that can go to the FCCU. That’s a good reason to raise HVGO cutpoint. But how to do it? Some people think the job can be done just by running computer models in the engineering office, relying on vendors and their data sheets for a clue to true equipment performance. Experience, however, shows it just ain't so. For either a grass roots project or a revamp, ...

Eliminate fouling of radiant tubes

Problem: An increase in Bridgewall temperature can be a symptom of excessive fouling of the fired heater’s radiant tubes. These tubes tend to oxidize under operating conditions. Solution: Our patented Hot Tube Descaling service removes radiant section process tube fireside soot, scale, and fouling during furnace operation.

Eliminate heat exchanger fouling with Watlow’s HELIMAX technology

Fluctuations within the heat exchanger to either the operating temperature or the mass flow rate are common causes of coking, which can lead to system failures and expensive downtime. Some heat exchanger design methods, like segmental baffles, have known dead zones where hot spots can occur, accelerating the coking process. Watlow’s HELIMAX ultra-efficient heat exchanger was designed to eliminate temperature-related failures. Leveraging our proven, patent-pending continuous ...

HYDROSAFE®, Watlow’s new indirect electric heat exchanger for dry gas seal applications, has been designed as a standardized thermal solution that minimizes custom engineering requirements because it can be adapted to a variety of conditions. The HYDROSAFE provides very flexible heating capabilities (12 to 31.2 kW) to compensate for changes in gas flow rates, or changes in gas composition, when interconnected to our purpose engineered WATCONNECT® control panel. Multiple ...

Is pinch enough?

Back in the late 1970’s and early 1980’s when fuel gas prices were high, energy utilization assumed major importance. A new method of calculating heat exchanger networks was developed. It was called Pinch Technology. Today pinch has been rediscovered by engineers who have access to fast computer simulation models. But as occurs with any older method that is rediscovered by a newer generation, enthusiasm generated by the rediscovery tends to obscure the deficiencies ...
