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.
Drive efficiency and sustainability through process optimization
Business philosophies often stress the importance of continuous improvement to gain sustainable competitive advantages.
Research and application of proprietary cold oil absorption technology in the recovery of refinery dry gases
With the increasing shortage of global energy and resources, the recovery and utilization of refinery dry gases have become important topics of concern.
Integrated column-reboiler system stress and flexibility analysis approach
In oil refineries and chemical plants, chemical reactions and separations take place in the distillation column.
Improving the sustainability of steam production
Steam distribution systems are a vital part of process manufacturing because steam is a versatile means of delivering carefully controlled heat energy, usually via a heat exchanger.
