an advancement in the end flash system equipment
date of patent: 4/20/2021
the combined end flash drum and a coil wound exchanger reduces the overall footprint and eliminates the need for large diameter back-end piping. this system is more efficient because of a reduced pressure drop of the lower pressure stream. the coil wound exchanger for end flash service is proven to be very robust and able to withstand the thermal stresses associated with this type of service.

balancing power in a split mixed refrigerant (mr) liquefaction system
date of patent: 3/2/2021
the system is configured to adjust characteristics of the high-pressure compressor to require less power when less power is available and more power when more power is available compared to the system’s design point. such adjustments allow for shifting the balance of power between the propane compressor and the high-pressure mr compressor to improve lng production efficiency.

natural gas liquefaction technology using a hybrid gas expander and mixed refrigerant cycle
date of patent: 12/15/2020
the patent covers a liquefaction cycle utilizing a closed loop cycle that employs gas expander refrigeration for precooling and liquefaction. the final subcooling is provided by a boiling nitrogen-methane mixed refrigerant. this technology is particularly useful for small to mid-scale liquefaction opportunities and where the procurement or production of hydrocarbon refrigerants is difficult.
