Troubleshooting a C3 splitter tower Part 1: evaluation
Distillation trays are prone to channelling and multi-pass maldistribution in large diameter towers. Multichordal gamma scanning is key for solving such problems.

Novel Approach in Troubleshooting Mathura Refinery CDU Column
An all inclusive approach may be essential to identify the problem as in this case where theoretical is compared with actual for identification of root cause. For chimney with overflow the arrangement provided can be considered as a fool proof and cost effective design (without consideration of a Forced IR). Column Internals affect Heat availability and in turn. Preheat. All Proof Internal designs may be essential for efficient performance of the plant. Read More ›

High-purity propylene from refinery LPG
A case study and financial analysis show that investment opportunities for refiners exist with the expected future high price of propylene. In a petroleum refinery, propylene is a by-product of fluid catalytic cracking (FCC), ...

A new approach to treating shale gases
Shale gas can be challenging to treat, but mass transfer rate-based simulation and appropriate tower internals can make it no harder to treat than other natural gases.

High-performance trays alone do not guarantee performance improvements
A high-performance tray does not determine the effectiveness of the whole column. Other distillation equipment plays a vital role in a successful column revamp.

Improving hydrotreater reactor performance
Case study of a kerosene hydrotreater shows that combining new and old technologies – a unique inlet diffuser with Raschig rings – can significantly improve liquid distribution and catalyst utlisation when producing ultralow-sulphur products in a trayless reactor.
