DCS Migration Strategies
12 November 2018

Is it time to rethink your distributed control system (DCS) expectations and capabilities? Reliable and effective control systems are critical for safe and profitable operations across process industries. Still, many industrial facilities today continue to operate using legacy control systems from the past four decades, often nearing the end of their lifecycles. Migrating to modern control systems can be a complex venture. These projects require detailed upfront planning, a methodical implementation strategy, and astute project management.

GT-UWC – How a Uniting Wall Column Maximizes LPG Recovery
8 November 2018

Find out how GTC Technology’s Uniting Wall Column provides several advantages and benefits over conventional cryogenic or non-cryogenic LPG recovery processes.  GT-UWC is a process uniting the functions of the deethanizer and depropranizer into one column to achieve higher C3+ recovery at lower operating temperatures and pressures. As a result, both capital investment and operating costs for grassroots and revamped applications are reduced.

The Low-Cost Revamp that Extended the Run Length of PTTGC's VDU
8 November 2018

When frequent fouling of the vacuum column was constraining the run length of PTT Global Chemical's (PTTGC) vacuum distillation unit (VDU) to significantly less than the downstream hydrocracker's three-year cycle, the refiner was quick to take decisive action. Discover how with a low-cost revamp of the unit to a Shell HVU using Shell's deep-flash, high-vacuum technology, the unit is now equipped to achieve run lengths in excess of three years.

Maximum Return on Investment from Catalyst Selection for a Hydroprocessing Reload
16 October 2018

Refiners continuously search for the best available options to maximize the return on investment for purchases. Since catalyst purchases are reoccurring and typically planned, these investments are critical to meeting financial targets. The optimum catalyst solution may incorporate different amounts of existing catalysts, replacement of one catalyst for another, or possibly a new, innovative catalyst approach to meeting refinery objectives. This paper examines three different refinery intentions related to catalyst selection for an upcoming hydrocracking unit reload: 1) reducing catalyst spend, 2) improving steady state operation, and 3) meeting new refinery objectives.
