Direct steam injection heating utilizing the Hydroheater

No matter what your industry or application Hydro-Thermal’s heating solutions will assure you saving energy costs, reducing maintenance down-time, and more. 

With instantaneous heating when you need it, our products are ideal for anywhere maintaining a precise temperature is critical. Our most popular heating applications include:

LIQUEFACTION/SLURRY MASH HEATING

DEPRESSURIZATION VAPOR CONDENSER SYSTEM (DVCS)

SLURRY TANK HEATING

• Hydro-Thermal’s solution reduces viscosity that provides additional flexibility for slurry solids adjustments and a reduction in downstream equipment load demand. It has also shown an improvement in corn oil yield. Finally, it provides a more uniform heating solution that eliminates mash hot and cold spots within the slurry tank. This will eliminate the need for tank sparging and also bring additional opportunity in potentially reducing enzyme dosing rates.
• A Hydroheater is used in the recirculation line and pulls from the coldest part of the slurry tank. The liquid is then re-circulated back to the slurry tank causing instantaneous mixing and more uniform temperature throughout the tank. Hydro-Thermal provides all work and materials necessary in this application, a turnkey solution with many benefits to boast.

CORN SYRUP PRODUCTION

• Using the Industrial Hydroheater prior to centrifuge eliminates residue build-up and reduces viscosity allowing for proper separation of corn oil from corn syrup.

CELLULOSIC PROCESS TECHNOLOGY

• Hydro-Thermal understands the importance of additional profit and revenue streams. Therefore, the Hydroheater/Jetcooker can be used to produce cellulosic ethanol. A bolt on process is used while pulling a slip stream from product that is already being produced at a standard ethanol facility.
• Utilizing the Jetcooker has many benefits including precise and accurate temperature control, increasing ethanol yield and corn oil production, as well as reducing energy costs.

CELLULOSIC PRETREATMENT

• Our heaters sufficiently hydrolyzes and opens up the structure of lignin-based biomass feedstocks to allow efficient and effective enzyme hydrolysis of the hemicellulosic sugars.
• Our product's straight-through patented design is ideal for thick slurries and high fiber content common to a wide variety of biomass feedstocks. Depending on the pretreatment process, Hydro-Thermal's solution can be designed and constructed around specific process conditions, such as high temperature, low pH and high pressures.

BACK SET HEATING

• Our direct steam injection heater is used to heat back set before going into the slurry blender to ensure that the ideal 185ºF is reached. The heater is strategically located after the cook water tank and cook water exchanger, but before the slurry blender so that benefits are achieved as the back set enters the slurry blender.
• For those who haven’t considered heating their back set, there are a lot of advantages. First, you have the flexibility of raising the temperature which allows for more uniform temperature of mash throughout the slurry blender/tank. Second, there is a potential for improved energy savings throughout the cook process. Third, the higher, more uniform temperature throughout the slurry blender and tank, allows for potential energy and enzyme savings. Plus, other equipment load demand will be reduced while being able to reach precise temperature set points.

BEER MASH SLURRY/BEER MASH COLUMN

• We have recently identified a new offering within the ethanol industry for precise temperature control. This includes installing a non-shear (Solaris) after the beer well but before the beer column for the existing mash stream.
• The goal is to provide a more consistent/accurate mash temperature to the beer column (135ºF current to 170ºF). In addition, there is an anticipated reduction in the beer column base loss, reduced energy usage and more flexibility/efficiency from the beer/mash exchangers, cleaning cycles and chemical usage. Finally, there is an expected reduction in the beer bottoms base loss.

CORN OIL PRODUCTION

• Hydro-Thermal’s products heat thin stillage/syrup beyond the normally targeted temperatures and can help ethanol producers achieve their minimum feed tag specifications. The result is increasing corn oil production numbers and ultimately increasing revenue.
• These products provide accurate and consistent temperature control. The added temperature works as an emulsifier. As a result, ethanol producers may be able to reduce or eliminate their emulsion breaker chemicals while still being able to maintain or increase oil production.

REVERSE OSMOSIS (RO)

• Hydro-Thermal can heat RO inlet water or heat membrane back flush water while achieving precise temperature control and eliminating wasted energy.
• RO filters are designed for a given water temperature. As water cools, it thickens and the RO capacity decreases. For every 1ºF below design temperature, a RO can lose up to 3% of capacity. A Hydroheater can keep the inlet water temperature at ±1ºF of the set point so the RO can operate at the designed capacity without wasting energy over heating the water.
• Similar to above, if the back flush water is heated to the designed temperature, they can optimize the amount of water used and ensure that the membranes are properly cleaned.
• See the resource section of our chemical or metal microsite for a general RO document.

CLEAN IN PLACE (CIP)

• Easily heats a one to three CIP tank system on demand.
• Proper cleaning and sanitation is an important safety concern for you and your customers. Hydro-Thermal’s solution allows you to clean equipment at the optimal temperature in one pass. It also allows you the flexibility to easily switch from tempered water to hot flush temperatures due to our technology’s internal modulation.

TANK HEATING

• Easily and efficiently heats tanks on in-feed or in recirc mode, trim heat.
• We can heat the fluid going into the tank; re-circulate the tank to maintain a specific temperature, or leave the tank cold and heat the liquid exiting the tank, producing hot water on demand. Many customers see a return on investment (ROI) in less than three months.
