After 25 Years at Cowan Dynamics – Happy Retirement Frank!

After 25 years with Cowan Dynamics, Frank is moving on to his next stage in life: a well-deserved retirement. Frank has started his career with us as a CNC lathe operator and all-around great machinist. He moved into the position of programmer, where his in-depth knowledge of machining processes really came to shine.His general helpfulness and willingness to go beyond the call of duty earned him the respect of management and his coworkers alike. Frank is now working on his golf game and hopefully will be equally successful at this new endeavor. From all of us: Happy retirement and see you on the links! Your friends at Cowan Dynamics.

What is an anti-surge valve?

An anti-surge valve is specifically designed and installed to protect the compressor from reaching its surge point. The valve is in the system, in a by-pass that connects the inlet and the outlet of the compressor. In normal operation, this valve remains closed, however, if the surge is detected, it quickly opens to maintain a minimum flow and directs the backflow to the outlet of the compressor to avoid damages. The valve must be completed with controllers that use the suction and discharge pressure and temperatures to determine the flow at which the condition of surge will occur. It is crucial for such valves to be operated by actuators that can achieve extremely fast stroking times, high frequency of operation minimal dead time and minimal overshoot. What is compressor surge?  In...

📖 Delayed Coking & Delayed Coker Unit Reference Guide

Coking Refinery Types Delayed Coking Delayed Coking is a refinery unit operation that upgrades the lowest value bottoms material (vacuum resid) from the atmospheric or vacuum distillation column and cracks it to the point that all of the resid is eliminated. This process yields lighter fractions and solid carbon into higher-value products and produces petroleum coke—a coal-like material. During the cracking process, a firing heater with horizontal tubes is used to achieve temperatures ranging from 485 to 505 C (905 to 941 F). Coking in the furnace tubes is, therefore "delayed" until the feed material reaches large coking drums downstream of the heater. You can produce petroleum coke in three physical structures: shot, sponge, or needle. Simply put, a delayed coking unit (DCU) processes...

The Importance of Valve Positioners

The valve positioner is a feedback mechanism. It allows valves to be positioned precisely in accordance with the output signal of the controller, in the presence of major disturbances caused by unbalanced forces acting on the valve stem, changes in actuator temperature, etcetera. Even a relatively small actuator, that otherwise would have to be bench-set to an unacceptable degree, can be stroked precisely when a valve positioner is used to signal the valve position. Positioners are not now considered to be the universal solution to many problems. In fact, in some control circuits the effect of fitting a positioner can be detrimental. Whilst it is an advantage to use positioners in slow systems, it can be a disadvantage in the case of control loops with short reset times. A positioner...
