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
