Abstract
Provided herein are methods, apparatus, and systems for delivering carbon dioxide as a mixture of solid and gaseous carbon dioxide to a destination. In particular, provided herein are kits for retrofitting a concrete operation to supply gaseous and solid carbon dioxide to concrete in the operation, where the kit includes a conduit to connect to a source of liquid carbon dioxide and to a carbon dioxide injector, the carbon dioxide injector, a second conduit to connect with the carbon dioxide injector, a third conduit to connect with the second conduit, and an intermediate processing unit.
Claims10
A kit for retrofitting a ready-mix or precast concrete operation to supply gaseous and solid carbon dioxide to concrete in the operation, wherein the operation mixes concrete in a mixer, comprising
- (i) a first conduit configured on a proximal end for connection to a liquid portion of a liquid carbon dioxide container and on its distal end for connection to a carbon dioxide injector unit;
- (ii) the carbon dioxide injector unit, comprising
- (a) a first carbon dioxide injection orifice,
- (b) an internal liquid carbon dioxide input conduit operably connected at a distal end to the first carbon dioxide injection orifice and at its proximal end to a connector for the first conduit, wherein the internal liquid carbon dioxide input conduit comprises a valve proximal to the first carbon dioxide injection orifice, and
- (c) a connector, distal to the first carbon dioxide injection orifice, for connecting to a second conduit,
- (d) a first pressure sensor for producing a first signal to be transmitted to a first receiver, and
- (e) a first temperature sensor for producing a second signal to be transmitted to a second receiver;
- (iii) the second conduit, configured on a proximal end to connect with the connector of (ii)(c) and configured on a distal end to connect with a third conduit;
- (iv) the third conduit, configured on its proximal end to connect with the second conduit;
- and
- (v) an intermediate processing unit, comprising
- (a) the first receiver,
- (b) the second receiver,
- (c) a processing system operably connected to the first and second receivers, wherein the processing system is configured to process the first and second signals and to produce a first output signal and a second output signal, the first and second output signals based, at least in part, on said processing, wherein the intermediate processing unit is configured to transmit the first output signal to a third receiver in the carbon dioxide injector unit and to transmit the second output signal to a batch control system of the ready-mix or precast concrete operation.
