Combination of Concentrating Candle Filters and Pressure Plate Filters for Removing Salts and Contaminants from Glycol Regeneration Units

March 2020
For the transport of Liquefied Natural Gas (LNG) in pipelines, monoethylene glycol (MEG) is added as corrosion inhibitor and to reduce the freezing point of the water in the LNG. The MEG is then reclaimed. This article discusses the use of a combination system for solid-liquid filtration as an alternative to static thickeners, centrifuges, filter presses and cartridges.

Use Bypass Dust, Reduce Energy Costs

May 2018
A new method allows the use of up to 100% alternative fuels (AFs) for clinker manufacturing and the recovery of the resulting bypass dust as a recyclable material. Indexing belt filters from BHS-Sonthofen enables the bypass dust accruing during clinker manufacturing to be completely reincorporated into the process by using up to 100% of more cost-effective AFs in cement kilns.

Glycol processing for the pipeline transport of natural gas

April 2018
New process for the efficient reclamation of glycol from natural gas | The recycling of glycol, which is added to natural gas for transport, is playing an ever-increasing role in the efficient and environmentally friendly operation of gas pipelines. BHS-Sonthofen has developed a new process that recovers significantly more glycol than conventional processes – and at a lower cost. It also features low maintenance requirements and works fully automatically. This makes the process particularly suitable for offshore operation.

Continuous Pressure And Vacuum Filtration Technologies as Alternatives to Batch Filtration Operations

September 2017
This paper discusses the selection of the filtration process systems: continuous pressure and/ vacuum filtration through a process of laboratory and pilot testing. These tests enable problem analysis, technology selection and scale up which help in optimum filter selection.

Thin-cake filtration technology to meet full containment for air-sensitive and toxic chemical and pharmaceutical production

February 2016
In many chemical and pharmaceutical processes, solid-liquid separation, cake washing and drying steps directly impact the effectiveness of the production operation. Further complicating these operations is the nature of the process and especially if the process is air-sensitive or toxic. This article discusses the choice of thin-cake (2-25 mm) pressure separation technology for full containment, no residual heel and their benefits to optimizing the effectiveness of the production process. For full containment, the paper then continues with a discussion of clean-in-place operations to meet current Good Manufacturing Practices (cGMP) guidelines including riboflavin test, validations and ANSI/ISA S88 and IEC 61512-1 batch process control systems.

Framework for Selecting Solid-Liquid Filtration Technologies for Particle Fines Removal

April 2014
In the manufacturing of chemicals, petrochemicals, pharmaceuticals, etc., after the initial mixing-reactions, there is always the necessity to remove the mother liquor from the process slurry. In some cases, the liquid is the valuable component, some cases it is the solids and in other cases it is both compounds. The nature of the requirements determines the type of equipment needed for the separation process. This paper provides an overview of separation equipment and then continues with a detailed view of technologies that can remove – recover small particle fines.
