Abstract
A SNG plant is now successfully under operation from December 1973 at Toyosu Works in Tokyo Gas Co. Ltd., employing CRG/HYDROGASIFICATION process developed by BGC to produce methane rich gas from naphtha with a capacity of 1, 110, 000 Nm3/d and calorific value of 9, 200 kcal/Nm3, containing 95% of CH4.
This process is controlled finely and steadily by DDC system designed by Tokyo Gas and easily turned up and down from 100% to 40% load according to the demand requested.
Production of SNG is significant for Tokyo Gas, now under way for conversion of town gas to natural gas.
In this paper the process flow and performance of this plant are described generally.
