SCA pulp and paper plant sets new standards

Sustainability and high plant availability are the main requirements of the paper and pulp industry. This goes for SCA as well, which operates its largest European integrated plant for the manufacture of tissue products in Mannheim, Germany. Among other products, some 120,000 tons of pulp are produced here annually in a continuous digester.

Challenges and solutions for molsieve dryer processes

Molecular sieves, or molsieves, are used in the refining and petrochemical process industries as adsorbents. They are mainly used in scenarios whereby very dry streams are required, helping to remove water and other oxygen sources to avoid catalyst deactivation and potential corrosion problems in the process plant. Molsieves exist in different pore sizes and their use varies between applications.

Suzano advances towards Industry 4.0

The Imperatriz Unit in Maranhão has adopted a solution that predicts faults in high criticality processes and reduces downtime for automatic on-off type valves.

Fugitive emission certified valves enhance process plants’ safety

Today’s guest blogger is discussing the growing challenges of emission control, what kind of standard compliance is required and how does a valve supplier answer to these demands.

Flow control for swing adsorption

Swing adsorption processes are used to separate or purify gases to produce industrial applicable products. Swing adsorption, whether it be pressure swing adsorption (PSA) or vacuum swing adsorption (VSA), is at the profit center for Industrial Gas manufacturers. The longer and more efficiently this process runs the more productive and profitable the plant will be. Interruptions in the supply of gases like hydrogen, nitrogen and oxygen are unacceptable to you, your customers, and to us.

Flow control for tank cars and transportation

Valmet is uniquely capable of delivering safe, reliable valves and flow control in quantities the tank car industry demands.

Flow control for energy

Facing increasing pressures to keep your power generating process up to code? Reliable valves and pumps help improve the productivity of your energy plant. We offer reliable valves, pumps and services for the energy industry.

How to choose control valves?

Control valve requirements often differ depending on the process area, application and end user specifications. Process conditions and the range of parameters also vary widely, including pressure, temperature, controllability, cavitation risk, environmental impact, noise and more. Plus, priorities may differ. An end user may want to know more about a valve’s performance, controllability and total life-cycle cost, whereas an EPC contractor may be more concerned about the CAPEX-related costs and delivery times. How do you know where to start – and where to turn for help with quality information you can rely on?

Neles Easyflow™ JT series angle stem tank bottom valves

Neles Easyflow JT series angle stem tank bottom valves provide a compact assembly with additional space for actuator clearance on insulated vessels. Large port has unobstructed flow to empty or fill the tank quickly. Quarter-turn operation and direct actuator mounting capability makes it easy to automate. Cavity fill and T-port options for the JT series ensure lowest possible dead volume and full draining of media from the valve.

Navigating high temperature challenges with Neles™ Neldisc™ butterfly valves

As process temperatures go up, the challenges for the flow control equipment increase gradually. Stepping above 250 °C requires most of the plastics and polymers to be abandoned and the selection of metallic materials instead. Furthermore, when the temperature rises above 600 °C, the challenges with the suitability of the materials require even more careful attention.
