What is StillPure?
The StillPure name denotes several styles of GLY-TECH designed vapor condensers for the capture of condensable vapors emitted from glycol reboiler still columns. The StillPure design allows for the removal of 99 percent or more of the condensable VOCs on an annualized basis.
What are VOCs and why is a condenser necessary?
VOC stands for Volatile Organic Compound. VOCs, as they apply to StillPure, are those hydrocarbon vapors emitted from a reboiler still column. They include Benzene, Ethylbenzene, Toluene, and Xylene from which the term “BETX” is derived. BETX and other VOCs are considered hazardous to health and the environment. For that reason, it is important to prevent their entering the atmosphere. Condenser alternatives include:
- Flare
- Thermal Oxidizer
- Carbon Adsorption
- Educator
What is a StillPure VOC Condenser?
A VOC condenser cools vapor from a still column and causes water and hydrocarbon liquids to fall out. When condensation is complete, the collected liquids are pumped to storage, separation, or waste. The remaining gas, or non-condensables, must be burned through a flare or thermal oxidizer, vented, or in the case of Strip Burn Technology, burned as fuel in the reboiler. A VOC condenser is not a vapor recovery unit (VRU) unless it has a means to “recover” the hydrocarbon vapor and place it into the process stream. While GLY-TECH’s G-10 series is a VOC Condenser, the G-20 and G-30 lines can be equipped to serve as VRUs, but do not come standard as one. The G-40 is the only true VRU standard to GLY-TECH’s product line.
The StillPure G-20 Series Overview
StillPure G-20 Series:
The G-20 is a single fan, forced draft condenser that uses a pneumatic pump and level control. It is an all-electric fan and coil unit only.Model G-20: How It Works:
The StillPure Model G-20 is an airflow condensing unit designed for the recovery of condensable volatile organic compounds (VOCs) from vapors emitted from a glycol reboiler still column during normal operation. The standard unit is self-contained and sits on a 42”x42” with a standard height of 10’. For some applications, a custom skid and frame can be provided to alter both the footprint and the height. As the vapor cools in the coil, it is condensed into component liquids. These liquids drain into a collection pot. A level control senses liquid accumulation and sequences a pneumatic or electric pump for liquid removal. A blow case can be utilized on some units. A slight glass is also provided to track fluid expulsion. Vapor leaving the reboiler still column is piped to the StillPure finned tube cooling coil. As the vapor passes through the coil heat it is dissipated by airflow over the inner surface. A laterally mounted thermostat controlled fan and motor provides the airflow. Each coil, fan, and motor is independently sized to the operating parameters outlined by the user. To increase and decrease the capacity of the StillPure Model G-20, it requires the re-sizing of one or more of these components. In some applications, Off Gas (non-condensable VOCs) can be piped to a flare, to a direct fired unit for combustion (using a special gas/air mixer) or to a low-pressure vapor recovery unit (VRU) to achieve 100 percent recovery. The StillPure Model G-20 is designed to remove 99 percent or more of the condensable VOCs on an annualized basis.Model G-20: Capacity:
The G-20 line offers a number of possible units based on capacity. The Armstrong fan and motor units can be sized for applications ranging from 10 MMcsf/day dehydration systems to 100 MMscf/day dehydration systems. GLY-TECH will determine the maximum vapor load to be condensed and offer the client an engineered solution to their still column vapor recovery needs.Advantages:
- Thermostat control guarantees consistent condenser performance.
- Off gas can be combusted in the fire tube or by a flare.
- Condensed hydrocarbon liquids can be collected and sold.
- Collection pot comes in code and non-code model.
- It possesses a small footprint.
The StillPure G-30 Series Overview
The StillPure Model G-30-PH:
The StillPure Model G-30-PH is a vertical air flow condensing unit designed for the recovery of condensable volatile organic compounds (VOCs) from vapors emitted from a glycol reboiler still column during normal operation. The G-30 is a dual fan, vertical forced draft condenser. The standard unit is self-contained and sits on a 12”x48” footprint with an overall height of 4’11’. For some applications, a custom skid and frame can be provided to alter both the footprint and the height. The Armstrong fan and motor units can be sized for applications ranging from 100MMscf/day dehydration systems to 500 MMscf/day dehydration systems. Even larger capacities can be handled with custom designs. GLY-TECH will determine the maximum vapor load to be condensed and offer the client an engineered solution to their still column vapor recovery needs.

Model Varieties
With the exception of the G-10-A ambient air unit, all models are thermostatically controlled. Units may be equipped with 2 or 3 phase condensed liquid collection pots. A Code stamped blow case is also available for evacuation of condensed liquids into low-pressure separation up to 150 psig. Units can be designed to handle dehydration systems with gas flow rates ranging from 10 MMscf/day to 1 BCF/day.
