Air and Gas Dryers

Internally heated dryer is an adapted form of heatless drier with extremely minimal purge air loss due to regeneration by dry air at low pressure and high temperature. Heaters are used to heat the purge air to roughly 180 degrees Celsius, which improves its moisture carrying capacity. This hot purge air is pushed through the desiccant bed at low pressure to regenerate with a tiny amount of purge.

The simplest of all desiccant-based air dryers is the Heatless Air Dryer. Two desiccant towers are employed in this dryer. While one tower is drying, the second tower is undergoing regeneration. A portion of the dry air from the in-line tower is used to regenerate the second tower. A sequence controller mounted in the control panel controls tower changeover every 5 minutes.

Air-N-Gas Process Technologies has developed systems to condition anaerobic digested methane for use in microturbines or combustion engines, as well as water vapor to protect gas compressors and remove water vapor from low-BTU gas to fulfil contract standards. Our refrigerated landfill/digester gas dryer was created particularly for this use. It’s a great way to get rid of hazardous water vapor and increase the combustibility of landfill gas and biogas, especially when the incoming gas temperature is between 40 and 45 degrees Celsius. Patented dew point sensor and flood level control, stainless steel heat exchanger tubes and moisture separator, and modular design for ease of maintenance are among the product’s characteristics. Air-N-Gas Process Technologies has long been a pioneer in the fields of absorbent desiccant, gas dehydration, and filtration.

Reducing the temperature is the easiest approach to remove moisture from compressed air. Compressed air is passed through a heat interchanger in a Refrigerated Air Dryer, and cold refrigerant at roughly 3 degrees Celsius is fed through the other side of the heat interchanger. Most of the moisture condenses at this temperature, which is subsequently separated and drained off in a moisture separator. The following is a list of notable features: -Non-cyclic procedure that is simple. -Operating costs are low. -Noise Reduction -Purge Loss: 0 -It is possible to dry even lubricated air. -Any capacity is possible. -PDP of 3 degrees Celsius -Electronic Command and Control -Refrigerant that is good for the environment

Part of the wet air is pumped via a heater to increase its moisture carrying capacity, which is utilised for regeneration, reducing purge loss. The entering moist air is separated in a distributor in this sort of drier. 60-70 percent of wet air is used for drying, while 30-40 percent is circulated via a heater, which raises the temperature of the air, removing moisture from the desiccant bed, and then cooling it in an after cooler, where moisture is condensed and drained out in a moisture separator. This air is returned to the distributor and mixed with incoming air before being disseminated once more.

The regeneration air in a Blower Purge Regenerative Dryer comes from a blower that is heated in a heating chamber, enhancing its moisture carrying capacity. For regeneration, this heated air is routed through the desiccant bed. The following is a list of notable features: -For large capacities, low operating costs are important. -It is possible to reach a dew point of (-) 60 degrees Celsius. -From 1000 CFM onwards, the most cost-effective. Limitations: -For regeneration, heat energy is required. -It is cost effective for High Flow Only because of the high capital cost.
