Development of an advanced, continuous mild gasification process for the production of co-products. Quarterly report, April 1--June 30, 1993
The primary objective of this project is to develop an advanced continuous mild gasification process and product upgrading processes which will be capable of eventual commercialization. The program consists of four tasks. Task 1 is a literature survey of mild gasification processes and product upgrading methods and also a market assessment of markets for mild gasification products. Based on the literature survey, a mild gasification process and char upgrading method will be identified for further development. Task 2 is a bench-scale investigation of mild gasification to generate design data for a larger scale reactor. Task 3 is a bench-scale study of char upgrading to value added products. Task 4 is being implemented by building and operating a 1,000-pound per hour demonstration facility. Task 4 also includes a technical and economic evaluation based on the performance of the mild gasification demonstration facility. Seven briquette tests were made to show the effects of different volatile matter contents of chars on coke quality. Higher char volatiles in the range of 7.52% to 14.14% produced better quality coke. This correlation was determined for a low volatile coal, Pocahontas {number_sign}3, and a mid volatiles coal, Sewell Lady H. Fifteen CMGU test runs were made using low volatile coal, Pocahontas {number_sign}3, and a mid volatile coal, Sewell Lady H. The 1,000 pounds/hour design coal feed rate was exceeded at 1,183 pounds/hour. Improvements to the vapor handling system were made including installation of a packed column demister and a tar trap condenser. Elimination of smoke emissions from the flare is in progress.
