Supercritical CO₂ Recovery Plant

Hops Extraction

We have already started collecting CO₂ and recycling it back to the process of Hops Extraction. Hypro successfully supplied a CO₂ Recovery Plant of 700 kg/hr capacity to YCH through ICC Group, United States. The technology – conceptualization by Hypro MD Mr. Ravi Varma makes the whole CO₂ System one of a kind. Hypro Engineers indigenously worked on the design, development, and manufacturing of the plant. Installation and commissioning of this extraordinary system to Yakima Chief Hops (YCH) are carried out successfully. Hypro has developed unique technology and method of CO₂ collection and further purification for Super Critical Hops Extraction Process. The recovery process post purification is a standard system and derives from our experience in CO₂ recovery for breweries.

Product Description

This CO₂ recovery plant is based on feed from a Hops Drying unit. This is comparatively low pressure system, less than 260 psi compared to 600 to 900 psig traditional systems. System averages the peaks which results into a smaller compact system for CO₂ Collection. It operates at high CO₂ Recovery efficiency exceeding 90 to 95% of recoverable CO₂. The purification and compression equipments from the oils and hop dust, ensures longer life and continual plant operation over long time periods.

In addition, CO₂ release to atmosphere will be cut down by more than 80% with this recovery system. We can also look at cutting down the new CO₂ purchase/day or in other words increase the CO₂ recovery further with an additional system and cut down on green house gas emissions and contribute to a greener and cleaner earth.

Functionality

The CO₂ from the extractors is vented out from the hops extractors at high pressure between 700 to 900 psig based on the hops variety and extraction process parameters. This CO₂ contains hop oils, hop dust, other hydrocarbon traces, oxygen, and moisture as impurities in it. These components get into the CO₂ during the supercritical hops extraction process. The challenge for recovery is that the large quantity of CO₂ 1500 to 1700 lb per batch at high pressure is released within 20 minutes. The system first collects more than 80 to 90 % of the released CO₂ into two pressure buffer tanks operating at pressures of 150 to 350 psig for the first stage and 15 to 65 psig for the second stage. The buffer tanks then release CO₂ for purification at a controlled outflow.

The purification step involves dust separation, oils mist or liquid droplets, aerosols separation by coalescing down to less than 0.1 um. The CO₂ is then fed to adsorption towers for separation of oil in vapor form, other vapor hydrocarbons, and moisture. The CO₂ is dried to a dew point in excess of -76 Deg F and odor compounds are removed. Further, this CO₂ is then fed to CO₂ condensation equipment. The CO₂ vapors are then condensed and the liquid CO₂ so received is distilled to remove Oxygen from it in a distillation column. The pure CO₂ is then collected and pumped into the day liquid CO₂ receiver and is recycled back to the hops extraction process. The CO₂ purity achieved by the process is in excess of 99.997 % v/v.

Frequently Asked Questions.

What impurities does CO₂ carry during Super Critical Hops Extraction?

CO₂ contains hop oils, hop dust, other hydrocarbon traces, oxygen, and moisture as impurities in it.

What is purification process of this plant is different than CO₂ recovery from Breweries?

The purification step involves dust separation, oils mist or liquid droplets, aerosols separation by coalescing down to less than 0.1 um. The CO₂ is then fed to adsorption towers for separation of oil in vapor form, other vapor hydrocarbons, and moisture.

How does this plant reduce CO₂ Emissions?

If on average 20,000 lb CO₂ was released to the atmosphere per day then this system would capture and recycle more than 16,000 lb/ day which means that the CO₂ emissions to the atmosphere would be cut down to 16,000 lb/day. The purchase of fresh CO₂ will now be no more than 4,000 lb/day.

Does this Plant Kill Mold?

Super Critical CO₂ Extraction kills all microbial bacteria, mold, and insects which results in pure Hops Extract.
