Integrated system to produce microalgae

An integrated system for the production and harvesting of microalgae, comprising:

• a reactor having a plurality of reactor nodes and a plurality of pipe elements, the plurality of reactor nodes and the plurality of pipe elements configured to create an isolated water culture suitable for algae growth;
• each of the plurality of reactor nodes having a module assembly having electronic components, analog to digital converters and solenoid valves, the module assembly configured to receive electronic input signals from other module assemblies in other reactor nodes;
• the analog to digital converters convert pressure signals coming from a reactor node where the module assembly is installed into electronic status signals;
• a computer to process the electronic input signals and electronic status signals and generate electronic control signals to control the reactor node where the module assembly is installed and electronic output signals to be transmitted to other module assemblies in other reactor nodes;
• feed the electronic control signals into the solenoid valves and generate output pressure signals to control the reactor node;
• an algae separation unit.

A method for the production and harvesting of microalgae using an integrated system, comprising:

• connecting a plurality of reactor nodes and a plurality of pipe elements to a reactor;
• isolating within each of the plurality of reactor nodes and the plurality of pipe elements water cultures suitable for algae growth;
• pumping water to a water degasifier using a plurality of pumps;
• heating water in the water degasifier using an engine;
• recirculating water from the water degasifier to the water degasifier using a heat exchanger;
• supplying a vaporizer with exhaust gases from the engine and with boil-off gases from the water degasifier;
• sublimating solid CO2 in the vaporizer using the boil-off gases from the vaporizer;
• extracting CO2 from the pre-cooled boil-off gases coming from the vaporizer;
• precipitating solid CO2 using a CO2 separator by further cooling pre-cooled boil-off gases coming from the vaporizer;
• and
• supplying solid CO2 to the vaporizer to replenish the solid CO2 supply in the vaporizer;
• supplying the reactor with CO2;
• growing algae in the water culture within the plurality of pipe elements.
