オフガス回収装置。A suction drum that cools the boil-off gas from the LNG storage facility with LNG liquid, multiple compressors that compress the cooled boil-off gas, a recovery line that sends the gas discharged from the compressor to the recovery facility, and recycling to the above-mentioned suction drum. recycling line,
In a boil-off gas recovery device equipped with a temperature control device that controls the suction gas temperature of the compressor, the temperature control device includes a detector that detects the flow rate of gas recycled to the suction drum, and an output signal of the detector. A converter for conversion, a differentiator for differentiating the output signal of the converter, an upper/lower limit arithmetic unit that receives the output signal of the differentiator and performs a limit calculation, and an output signal of the upper/lower limit arithmetic unit and the above-mentioned suction The apparatus is equipped with an adder for adding a correction signal to keep the drum outlet gas temperature at a predetermined direct value, and an LNG liquid control valve that is operated by going up to the adder and changes the LNG liquid flow rate supplied to the suction drum. Characteristic boil-off gas recovery equipment.
