Methods and systems for removing drilling fluid from wet drill cuttings are described. According to some embodiments, the method comprises: at a pressure above atmospheric pressure: using an internal combustion engine, combusting an air-fuel mixture comprising air and a hydrocarbon-based fuel, thereby producing a combustion exhaust at a first temperature; providing the combustion exhaust to the wet drill cuttings to contact and directly heat the wet drill cuttings by convection so that at least some fluid is evaporated therefrom and at least some dry solid drill cuttings remain, the evaporated fluid comprising drilling fluid and water; condensing at least a portion of the evaporated fluid to produce condensed drilling fluid, water and non-condensable inert gas; and separately recovering the condensed drilling fluid, the water and the dry solid drill cuttings.

Systems and methods for removing drilling fluid from wet drill cuttings are described. According to some embodiments, the method comprises, at a pressure above atmospheric pressure: combusting a rich air-fuel mixture at a rich combustion temperature, thereby producing a generally low oxygen, inert rich exhaust; providing said rich exhaust to the wet drill cuttings to contact and directly heat the wet drill cuttings by convection so that at least a portion of the drilling fluid is evaporated therefrom and at least some dry solid drill cuttings remain; condensing at least a portion of the evaporated drilling fluid to produce condensed drilling fluid; and separately recovering the condensed drilling fluid and the dry solid drill cuttings.

An abatement system for pyrophoric chemicals where the materials are captured or controlled by a hazard volume and fed to a vaporizer in an oxygen deprived environment. Materials are heated until vaporized while mixed with nitrogen. The mixture exits the system through a reaction column. The system is monitored by oxygen sensors, smoke detectors and temperature sensors.

The present disclosure is a method of removing contaminants from a feed stream comprising said contaminants and process liquid by bringing the feed stream into contact with a heated heating fluid in or in proximity to a separation vessel thereby causing process liquid to vaporise and flow out of the separation vessel as vapour, after which it can be recovered. Embodiments of the method may include using a heavy heating fluid whose density is higher than that of the feed stream and/or vigorously agitating the pool of heating fluid in the separation vessel.

A groundwater remediation system includes a capillary media supported and positioned such that it is partially submerged into a groundwater source to be remediated. Groundwater is drawn into the submerged portion of the capillary media and further into the non-submerged portion of the capillary material via natural capillary action. As the water evaporates from the non-submerged portion of the capillary media, the dissolved solids within the water precipitate onto the media leaving the precipitated solids for reclamation or disposal and allowing the cleaned water vapor to disperse into the ambient air. In some embodiments, heat may be added to the media, water, or air to accelerate the evaporative process.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.
