Processing Facilities

The processing units in our Harwich Manufacturing Centre comprise batch and continuous distillation facilities:

In Harwich, perfect conditions are available, such as considerable process efficiency thanks to optimised and modern production units and high plant availability:


Batch Distillation Plants

A 2-batch distillation units which can also be linked together to operate as a single, two column distillation plant either fully continuously or in a semi-continuous mode. Throughput varies depending on operating mode and feed composition.










Condensate Distillation Plant

A 4-column continuous distillation plant, principally designed for the fractionation of North Sea Gas Condensates (or similar streams such as Pipeline Interfaces or mixed hydrocarbon streams) into a variety of distillate fractions. Throughput up to 30mt per hour depending on feed composition. Typical processing campaigns of 1,000 to 10,000mt.











High Vacuum Distillation Plant

A 3-column continuous distillation plant designed primarily for high vacuum operation, with low internal pressure drop, to fractionate speciality Gas Oil and heavy Aromatic feedstocks at the lowest possible column base temperatures to minimise product degradation. It is, however, also possible to process North Sea Gas Condensates and Pipeline Interfaces on this plant. Throughput up to 25mt per hour depending on feed composition. Typical processing campaigns of 1,000 to 5,000mt.









High precision in-tank blending

High precision in-tank blending of multiple components to meet a bespoke customer specification. 


In addition to the above distillation facilities the site offers the Perco® sweetening process and soda lime treatment to improve product odour.

In recent years, Haltermann Carless has made important investments to enhance the sustainability and energy efficiency of our production site in Harwich. We have made significant process improvements to our production units to reduce the energy consumption of our processes, thereby reducing the CO2 footprint per tonne produced product.



Our strong efforts have been honoured with the Gold Status of Ecovadis.

Custom processing

Custom processing is gaining more and more acceptance. In addition to manufacturing our own high-quality products in Harwich, we offer custom processing for other suppliers and customers. Haltermann Carless is your partner of choice if you are looking for additional processing capacities to absorb order peaks, supplementary process technologies or want to outsource secondary processing to use your own plants with a higher added value.

Decreasing costs, shorter delivery times and quality that meets the highest industry standards are among the undisputed advantages of external production.

In Harwich, ideal conditions are available, such as considerable process efficiency thanks to optimised and modern production units, as well as high plant availability. We offer our customers a high quality assurance through modern laboratories connected to the production as well as a best location at the port with connections to all transport routes.
