New Projects

Designed and commissioned multivariable controllers on integrated Crude, Vacuum, Coker, and Hydrocracker units to maximize profitability of middle distillate production. The customer chose Hall Controls to lead this important project at their recently completed refinery expansion based on our excellent track record of delivery results.
Designed and commissioned multivariable controllers for a refinery’s Crude, Vacuum, and FCC to maximize seasonal gasoline or diesel production. The controllers coordinate control and optimization for the Crude and FCC Units.

Revamps

Updated, revamped, and commissioned a multivariable controller to push distillate recovery, control product qualities, and optimize heat recovery for an integrated crude and vacuum unit. The multivariable controller is used in conjunction with a Real Time Optimizer (RTO).
Updated, revamped, and commissioned a multivariable controller to push feed rate and LCGO recovery for a delayed Coker unit.

Trained a refinery process control group on techniques and tactics of advanced control. The practical course gave the site engineers the knowledge and tools to improve the safety, environmental, and economic performance of the refinery. The course included PID, advanced control strategies, and multivariable control. The course culminated with the actual implementation of a multivariable controller on the reformer stabilizer column. Hall Controls believes that the most effective training must include "hands on" involvement.
Completed company-wide audit for advanced control on six (6) FCC Units. The audit benchmarked APC, audited performance, included gap analysis, and identified opportunities for the future.

Fixed a crude unit multivariable controller that had been implemented by a different control services supplier. The matrix and objective function for this controller had numerous errors and inconsistencies which prevented the application from achieving it's potential. Hall Controls reworked the controller to achieve maximum benefit.
