2020年4月1日 1.1.1. Accumulated bridge plug treatment residue in wellbore, resulting in plugging At present, most of the shale gas wells in the Sichuan–Chongqing region are stimulated by way of bridge plug + clustering perforation + staged sand fracturing.
2021年3月5日 The industrial garnet sand samples have a grain size between 120 and 300 mesh and include two recycled garnet sands, one garnet sand from India, one from South Africa and two of unknown origin
2019年12月18日 After the bulk removal in the BTF, the remaining H 2 S can be removed by adsorption to activated carbon. The technology is fully proven; active carbon is cheap and has a high capacity [36,37,38].At some biogas facilities, activated carbon may be the only removal technique installed to reduce investment cost and minimize air contamination
2016年3月24日 The advantages and disadvantage of the newly proposed procedures are outlined and reviewed. Undoubtedly, adsorptive-based methods have achieved many advances in this area. Particularly, surface imprinted polymers and metal–organic frameworks have manifested an excellent tendency to remove bulky sulfur compounds
