How important is connected pipework to PSVs?
The purpose of this article is to explain additional process considerations for pipework connected to PSVs, such as isolation valves, layout, orientation, forces and moments.
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).
Refinery/petrochemical makeup water treatment: A general guide for technical personnel—Part 1
New personnel are often confronted with challenges that require knowledgeable and quick action, which they may have difficulty providing without thorough training. A very important—and sometimes overlooked—unit operation within these facilities is makeup water treatment for steam generators and other processes. Many cases have been documented in which makeup system upsets have led to boiler tube failures that partially or completely shut down unit processes. Parts 1 and 2 (September 2024) of this article serve as a guide for those employees who may be on a steep learning curve when it comes to makeup system understanding.

Olin Corporation, a leading global manufacturer of chemical products and ammunition, announced that it has lifted its systemwide force majeure on chlor-alkali products declared on July 10, 2024.
AM Green Ammonia reaches FID on its first MMt green ammonia project in India
AM Green Ammonia B.V. has achieved final investment decision (FID) for its first million-ton (MMt) green ammonia project located in Kakinada, Andhra Pradesh, India.
Digital Feature: Truly effective reliability requires predictive maintenance
To navigate this new world, organizations must find ways to bring in new technologies to support the limited personnel they have, but without increasing the complexity of those people’s jobs or overwhelming them with raw data they are not trained to use. The solution is to implement a predictive maintenance technology plan founded on a boundless automation vision of seamlessly moving contextualized data wherever it is needed.
Honeywell expands licensing agreement to support energy transition with new flare technologies
Honeywell announced a significant expansion of its licensing agreement with AFG Combustion and its subsidiary, Greens Combustion Ltd., to include Callidus flares. This expanded agreement not only doubles the range of greenhouse gas-reducing Callidus Ultra Blue Hydrogen process burners but also enhances global customer support.
