Abstract: Aspects herein use a Digital SRM (DSRM) with a maintenance user interface. In one embodiment, the DSRM is a Knowledge Graph (KG) of nodes and edges which uses natural language processing (NLP) and image processing to retrieve relevant information derived from SRM PDF documents. In the KG, Entity descriptions contribute to one another, forming a network, where each entity represents part of the description of the entities in which each entity is related. The entities have properties describing each entity and each entity is interlinked via relationships such as allowable damage limits (ADL).

Abstract: A method for automated damage assessment includes receiving input data identifying an aircraft, a location on the aircraft, and damage information associated with the location. The method also includes automatically identifying a plurality of maintenance conditions based on the input data and a three-dimensional model of the aircraft. The three-dimensional model includes a first layer associated with a first set of structural features of a portion of the aircraft and a second layer associated with a second set of structural features of the portion of the aircraft, where the first set of structural features is distinct from the second set of structural features. The method also includes obtaining a damage limit from a digital service manual, where the damage limit is based at least on the plurality of maintenance conditions. The method also includes generating a maintenance disposition based at least on the damage limit and the input data.

Abstract: A method for reducing the level of elemental sulfur from sulfur-containing hydrocarbon streams as well as reducing the level of total sulfur in such streams. Preferred hydrocarbon streams include fuel streams such as naphtha and distillate streams that are transported through a pipeline. The sulfur-containing hydrocarbon stream is blended with an aqueous solution of water, a caustic, and at least one metal sulfide thereby resulting in an organic phase and an aqueous phase. The blended stream is then passed through a bed of solids having a suitable surface area so that a substantial amount of the sulfur moieties are removed by the aqueous phase.

Abstract: A process for reducing the level of elemental sulfur from sulfur-containing hydrocarbon streams, particularly refined fuel streams such as gasoline that is transported through a pipeline. A mercaptan compound is mixed with the stream prior to, or after, the stream is pipelined.
