20140617 NL GUTS Presentations Distillation - Thermal Separation

Group of Users of Technology for Separation in the Netherlands




20140617 Drystill Inc. (Can.) - Mr. Ian MacGregor – “Pass-Through Distillation, first results”

Drystill’s sister company Fielding operates the largest solvent recovery plant in Canada. Several of the technologies used there (pervaporation, Stripper Absorber Module) are owned by Drystill. This SAM is the heart of the pass-through distillation pilot unit. The principle is to place a water absorbing fluid between the evaporating phase and the condensing phase, while transported by a gas.. This enables separated process conditions in the evaporating and the condensing phase with low distillation temperatures when vacuum applied.

Fielding incorporated this principle at the permeate side of a pervaporation unit reducing deep cooling. The SAM with very short heat and mass transfer distances makes this possible. Design calculations were presented. www.fieldchem.com


20140617 Pathema BV – Mark Boeren- “Technoproject results: Energy Efficient Degassing using Vortex Technology”

The start-up company Pathema installs and markets the IVG Vortex technology. Originally used in water degassing this NL GUTS sponsored Technoproject validates the use for degassing water based process liquids of Heineken (Cooling water of evaporative condenser) and FrieslandCampina (RO permeate and dairy liquids) In dairy both high and low viscosity liquids can be degassed. IVG is faster than conventional degassing in venting tanks, but a venting tank cannot be omitted. For the evaporative condenser IVG resulted in chemicals free operation, higher concentration cycles (saves water intake), reduced biological growth, no corrosion, clean heat exchanger elements and 100% water recycle option with acceptable payback time. www.pathema.nl


20140617 ECN – Jan Aiso Lycklama – “Energy optimization in Distillation by using heat pumps”

In an ISPT project ECN, TUD and Bronswerk cooperated to explore the potential of different heat pump configurations for AkzoNobel, Lyondell-Basell,, Huntsman, DSM and Jacobs. Presented were the principles and components of Mechanical Vapor Recompression and Thermo-acoustic Heat Pumps; TAHP was discussed in more detail with the test rig and a PFD of integration in a distillation unit. Proof of Principle has been shown. Economics look good. www.ecn.nl


20140617 TU Delft – Carlos Infante Ferreira – “Heat Pumps in Bulk Separation Processes”

For the same ISPT project TUD studied the Compression Resorption Heat Pumps CRHP. Analysis of different mechanical heat pumps favored the CRHP. After 50 industrial cases considered, the performance appears case specific, requiring parameter optimization. Design and economy affect each other. >60% energy savings are possible with 3 years payback times over conventional boilers for temperature lifts up to 124K. Findings have been published in several papers. www.tud.nl


20140617 GreenTEG AG (CH)– Robin Born - “gSKIN sensors for controlling and optimizing thermal processes”

As a spin-off from the ETH Zürich (CH) greenTEG develops and manufactures heat flux sensors, very small non-invasive devices that are attached to the walls of thermal equipment, like reactors, distillation columns, heat exchangers etc. The temperature difference between wall and reference side of the greenTEG sensor generates a voltage proportional to the heat flux. As the sensor is cheap, placing a number of sensors on thermal equipment makes surface and bulk temperature profiling relatively easy and also makes possible measuring reaction energy, evaporation energy and to follow deicing. The sensor signal may serve as input for heat control. www.greenTEG.com/products/gskin-heat-flux-sensor


20140617 IP&D Experts – David Hollestelle - “Technoproject results: Functional High Quality Algae Powders”

IP&D specializes in developing and optimizing drying and powder processes and equipment and provides training. A special challenge is to dry bio-materials maintaining functionalities especially for nutri- and pharmaceuticals or cosmetics and oil with algae as a source. Together with NL GUTS members Kerry and Sensus (Cosun) the NoWiTec fluid bed drying technology of University Magdenburg was validated on different algae. This FB dryer uses natural carrier particles on which the algae paste is precipitated as a layer by layer coating. This enables fast drying at low temperatures avoiding loss of functionality and a pasteurized product at feasible cost. Market feasibility is next step. www.ipdexperts.com


20140617 EnerGQ B.V. – Ton van Ewijk – “Intelligent energy saving; Measuring gives information but measuring and analysis will give energy efficiency”

With focus on industrial energy consumption EnerGQ’s big data analysis tool and proprietary algorithm process data of multiple sensors and measuring devices of different energy carriers, electricity, steam, gas etc. of a process. These data are compared with historical data collected by the same equipment. Excessive energy uptakes are analyzed from deviations and immediately calculated to savings. The outcomes assist plant operators and management to real time correct process and operating conditions and settings. Experience shows 10-30% energy saving. It serves as investment decision support and operator training tool. www.energq.com


20140617 Dishman Netherlands B.V. – Mieke Sibeijn – “Development and design of the new production plant at Dishman Netherlands”

Dishman Netherlands produces cholesterol and lanolin alcohols from wool grease plus Vitamin D and analogs for pharma, cosmetics, food/feed and technical applications. The process consists of 1) saponification (followed by solvent extraction steps to separate lanolin alcohols from lanolin fatty acids; with solvent recovery) and 2) cholesterol purification (involving chromatography, crystallization, filtration, drying and milling) to produce lanolin alcohols and two cholesterol fractions. With external experts from the NL GUTS network improvement options from a previous scan of the process have been implemented: lay-out, acid wash, sulfate removal from aqueous waste stream, reboiler on rectifier (no live steam) resulting in lower energy consumption and improved environmental performance. www.dishman-netherlands.com
