    Do You Have a Mechanical Seal Refurbishing Shop in Your Complex?
    (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016) Sabharwal, Mohit; Kumar, Arun; Paliwal, Dilip
    Case Study 24: Author intends to convey: 1. Importance of having Mechanical Seal Refurbishment facility in a refinery complex, supported by interesting case studies on critical mechanical seal failures. Minimum set up required for In-house Mechanical Seal Refurbishment facility. 2. The success story of having a Mechanical Seal Refurbishment facility at 9MMTPA Grass Root Refinery, which proved a major factor in timely project completion and vital during the safe and successful refinery commissioning and steady state operations. 3. At what stage the Mechanical Seal Refurbishment facility should be functional in the project?

    Save Your Centrifugal Machinery During Commissioning
    (Texas A&M University. Turbomachinery Laboratories, 2014) Kumar, Arun; Sabharwal, Mohit; Turbomachinery Symposium (43rd : 2014)
    During the commissioning of centrifugal machines (Compressors, steam turbines, pumps, fans etc.), a lack of flushing, inspection and ignorance of critical areas & procedures can lead to major problems, damage, and serious safety issues. These serious issues and damages lead to a delay in startup of the refinery, resulting in large monetary loss & further delay as major spares required to carry repairs may not be available in initial stage. It is possible to prevent such damage by following the procedures and inspections which are discussed in detail in this paper. The tutorial covers the experience and learning derived by the commissioning of more than 5,000 rotating machinery equipment over the past 5 years. The Tutorial will illustrate what can go wrong with centrifugal machinery during commissioning and startup and actual case studies of damage are provided along with the corrective and preventive measures suggested for successful commissioning. A Checklist of Do’s and Don’ts to be followed before and during commissioning is also provided.
