In sulphur handling facilities, deviations in product consistency are often an indication of issues impacting not only the quality of end product, but also the production process itself. In this article, IPCO explains why shape and quality really do matter.
Diaphragm seals are applied when pressure or level transmitters need to be protected against harsh conditions like the corrosive ammonium carbamate in urea plants. The process pressure is transmitted via the flexible diaphragm and transmission fluid to the measuring instrument as shown in Fig. 1 below.
Begg Cousland Envirotec reviews different mist eliminator types and some of the operational problems encountered which can be managed by correct installation, targeted cleaning or replacement, and selecting appropriate corrosion-resistant materials.
The convection section of a syngas reformer is vulnerable to creep, corrosion, erosion, fretting and fouling which can cause deformation, local metal loss and failures that risk plant shutdown. Inspection access is limited, but solutions are available. Quest Integrity discusses life management of the reformer convection section to reduce unplanned outages.
This article describes an unusual tube failure incident which resulted in fire escaping the furnace box during normal operation of a hydrogen plant. Ken Wohlgeschaffen of Chevron Products Company shares the sequence of events leading up to the incident, the extent of damage caused by the incident, and most importantly the causes and lessons learned from this incident to prevent recurrence.
NextChem (Maire) is awarded a three-year engineering and technology services contract by Satorp in Saudi Arabia to improve energy efficiency and carbon footprint
