A guide wire control device and methods of use are described herein. A novel method for optimizing a guide wire for a patient is described. The method includes steps of scanning a patient's anatomy and then fabricating, or selecting, a guide wire with optimal geometry for a particular patient and/or procedure. The guide wire may optionally be secured to a guide wire control device for improved control during transcatheter surgical procedures.

Patient specific guide wire method

Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.

Renewable diesel production with heat release management

Systems and methods are provided for performing hydrodeoxygenation of bio-derived feeds while maintaining the hydrodeoxygenation catalyst in a sulfided state. During hydrodeoxygenation, a hydrogen-containing stream is provided to the hydrodeoxygenation reactor as a hydrogen treat gas to provide hydrogen for the reaction. In some aspects, the hydrogen treat gas used for hydrodeoxygenation can be formed at least in part from hydrogen that has been used as a stripping gas for removing HS from a rich amine stream. In other aspects, HS can be stripped using water vapor, and a resulting overhead HS stream can be compressed prior to incorporation of the HS into a hydrogen-containing stream. The resulting hydrogen-containing stream can include sufficient HS to substantially maintain the catalyst in the hydrodeoxygenation stage in a sulfided state.

Renewable distillate production with continuous catalyst sulfidation

Disclose is an online analyzer to monitor conversion of a biofeedstock in a first hydrotreating stage to avoid catalyst poisoning in a subsequent stage. An example method of processing a biofeedstock may comprise hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock. The method may further comprise monitoring conversion of the biofeedstock in the hydrotreating with an online analyzer.
