SMR feed effluent hairpin exchanger: Once upon a time—An unusual thermal mix-point failure—Part 2
This article presents a review of a failure that happened in a hairpin heat exchanger type on the shell side in a H2 (H2) reformer unit.
SMR feed effluent hairpin exchanger: Once upon a time—An unusual thermal mix-point failure—Part 1
This article presents a review of a failure that happened in a hairpin heat exchanger type on the shell side in a hydrogen (H2) reformer unit. This mechanism was not identified during the design phase and led to a failure after only two years of operation. This article also reviews the situations encountered during the design stage and how they affected the material selection.
Iraq's Kerbala refinery to operate at 50% in coming days
Iraq's Kerbala refinery will operate at around 50% capacity in the coming days. The refinery will process around 60,000 bpd as four of its eight heat exchanger units will stay offline for extensive maintenance
Kurita America launches Kurita Dropwise Condensation Technology in North America
Kurita America, part of a leading global provider of industrial water treatment solutions the Kurita Group, has introduced Kurita Dropwise Condensation Technology in the North American marketplace.
Retrofitting CO2 capture in a petroleum refinery
This article examines the application of solvent absorption-based post combustion capture for refinery/site-specific factors and quantifies the impact this will have on CCS CAPEX/OPEX. This analysis helps to determine the optimum approach for any individual refinery site.
Review steam system designs to accelerate chemical industry decarbonization
Industrial steam systems range from simple systems comprising a low-pressure single steam user to a complex system with multiple pressure levels, multiple generators and multiple users integrated with an onsite cogeneration facility. This article will present the typical CO2 emissions estimates for chemical and petrochemical facilities and describe options available to reduce these emissions through additional heat integration, fuel switching, and the use of heat pumps and electric boilers.
The purification of benzoic acid using dividing wall columns
In one recent project for a customer based in Asia, the authors’ company suggested the combination of distillation and crystallization techniques to obtain high-quality purified benzoic acid. Encouraged by the successful startup of this processing train, the customer began to schedule a second project. The authors’ company was asked to optimize the purification process to improve cost and operational efficiencies. The two existing columns, which remove lights and heavies, respectively, from the crude benzoic acid feedstock were investigated to identify key opportunities. The feasibility study based on the feed composition confirmed that the existing columns could be converted into a single dividing wall column (DWC).
Digital Feature: Minimizing the cost of corrosion: Budgeting for industrial asset preservation
Advanced budgeting for corrosion protection is critical to industrial facility management. Since the urgency of the matter is often not realized until a failure or accident occurs, the article provides several tips to help maintenance, purchasing or corporate teams start budgeting for preservation before an emergency happens.
