We continue our 5 Questions for an Emerson Expert podcast series with Sudhir Jain. Sudhir has vast experience in consulting with oil & gas upstream, midstream and downstream producers as well as many other process industries. He shares his path to where he’s at today, a recent challenge he’s faced working with an offshore oil & gas producer, what he enjoys outside of work, and advice for new control and automation folks entering our ranks. We’ve featured Sudhir and his expertise in many posts over the years.
If there is a particular Emerson expert you’d like to hear about and a specific question you’d like me to ask them, leave a comment below… thanks!

Storage tanks play a pivotal role in the supply chain from upstream oil & gas production through downstream petrochemical-based products. Separation of water from the hydrocarbon liquids during storage create the need for operations to remove and treat this water as it builds up over time.
Emerson’s Ryo Hashimoto
shared a story of an Asian petrochemical manufacturer who had numerous naphtha and pyrolysis gasoline storage tanks. During the process of storing naphtha in the tanks, water would collect and accumulate at the bottom of the tanks due to its specific gravity. The water at the tank bottom would need to be drained over time to prevent it from flowing into the process.
The water draining process, performed on a quarterly basis, takes up to two to three hours and the operations staff must monitor for any hydrocarbon leakage to prevent oil loss, leakage of naphtha into the drain sump located at the tank area, and additional treatment work needed to remove hydrocarbons from the drained water.

Wikipedia defines cavitation as:
…the formation of vapour cavities in a liquid – i.e. small liquid-free zones (“bubbles” or “voids”) – that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave.
These shock waves can result in serious damage to control valves where these rapid changes in pressure can occur. This 5:56 YouTube video on cavitation clearly describes the phenomena, its impact on valves, and ways that it can be eliminated or significantly reduced. Continue Reading ▶
As sensors and final control elements grow ever smarter with digital diagnostics and communications paths, the need to make sense of this data to improve safety, reliability and efficiency also grows. Not only is improved analytic software required to help spot trends and abnormalities, but also experts to help provide guidance to put this information into action.
In this 5:07 video, Emerson Connected Services Valve Monitoring (Stuck Valve Scenario), Emerson Group President-Final Control, Terry Buzbee describes how suppliers such as Emerson can provide this remote expertise around technologies and applications for manufacturers and producers.

For those not in the pharmaceutical and biotech manufacturing industries, if you ever visit one of these facilities you’ll be struck by the clean, shiny stainless steel vessels and piping. Given the importance of hygiene in the production of medicines, most processes include clean-in-place (CIP) and sterilize-in-place operations (SIP). The capital costs and ongoing time requirements for this stainless-steel equipment and CIP and SIP system operations is not insignificant.
In a BioPharm International article, Automating Bioprocesses
, author J. Markarian interviews Emerson’s Michalle Adkins
and Bill Smizaski
to discuss single-use systems (SUS).
These are a trend in helping reduce capital project costs and in avoiding the ongoing time requirements of CIP and SIP operations.
When asked about the primary differences of SUS versus conventional approaches, Michalle and Bill noted that the: Continue Reading ▶
