Bosai Energy was founded by professional engineers and managers who have been in the field of gas project development and power management for many years, they've successfully managed over 20 installations of LNG plants and several distributed power plants.
Bosai Energy continuously improves gas purification and liquefaction technology for LNG plant, the ability of engineering design and equipment fabrication empowers Bosai Energy to provide international clients with the best solution on LNG plant and distributed energy management. Bosai Energy is growing to develop entire value chain of LNG business and invest in renewable natural gas business.
Bosai Energy works with China Academy of Science on cooperative research of cryogenic technologies and continously improve the liquefaction efficiency for LNG plant.
The SMR process is optimized for minimizing total energy consumptions of compressors and pump, and the control variables are summarized on compressing ratio of each compressor, mixed refrigerant flowrate, composition of mixed refrigerant, and mixed refrigerant temperature.
Bosai Energy is capable of engineering design per international standards for LNG plant ranging from 12,000 GPD to 500,000 GPD and distributed power plant ranging from 500kW to 25 MW.
Our design team provides a complete solution customerized for each specific demand, which allows to deliver the reliable equipment at competitive price. The standardized design covers the LNG plants for flare gas, wellhead gas, pipeline gas, and biogas paired with power plant as needed.
The purification skid comprises of gas metering and pressure control system, filter system, and CO2 removal system. The feed gas comes from the water jacket furnace skid through the gas metering and pressure control system is sent to the filter system.
A coalescer filter is fitted with coalescing cartridges in order to remove liquid hydrocarbons from the feed gas. If the feed gas contains oil, the feed gas coalescer filter system will remove 99.97% of liquid particles above one micron. The feed gas will then be sent to the CO2 Absorber Tower.
The feed gas circulates through a coalescer filter and is contacted at high pressure with the solvent. The treated gas is then cooled and sent to the gas dehydration and demercuration skid.
The treated gas from the CO2 absorber tower will be water saturated, and the water must be removed before the gas can enter the liquefaction skid. The Sweet Gas Cooler reduces the temperature of the gas exiting the absorber to condense out some of the water. The cooled gas is then sent to the molecular sieve type Dehydration Beds.
This cooling upfront of the dehydration improves the efficiency and reduces the size of the beds.
Cooling box is a core piece of equipment in the LNG plant whose main function is to provide cooling capacity for purified natural gas and reduce its temperature until the feed gas has been liquefied.
In aaccordance with gas source condition of the project, liquefaction process of the project adopts a precooled MRC process. Purified natural gas going through pre-treatment unit enters into the liquefaction cooling box and goes through grade I, II and III heat exchangers in the cooling box and produce LNG.
Renewable Natural Gas
Bosai Energy is working with potential technology providers on producing RNG in Canada, the feedstock is gasified for biogas which will be further purified for syngas, ultimately RNG is produced in the methanation unit.
The RNG plant will greatly help reduce CO2 emission while the waste heat from methanation is recycled for local facilities.
The technology can be duplicated in different locations to help CO2 emission, and provide stable local jobs.
