US Patent:

43542425, Oct 12, 1982

Filed:

Dec 15, 1980

Appl. No.:

6/216725

Inventors:

Charles A. Ganster - Houston TX
Gerald V. Nelson - Nederland TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C10G 2100
G06F 1546

US Classification:

364501

Abstract:

A control system controls the temperature of gas oil being charged to a reactor in a hydrotreating unit. The control system includes a heater which heats the gas oil in accordance with a control signal corresponding to a desired temperature. A gravity analyzer senses the API gravity of the gas oil and provides a corresponding signal. A sulfur analyzer senses the sulfur content of the gas oil and provides a representative signal. A boiling point analyzer senses the 50% boiling point temperature, the initial boiling point temperature and the end point temperature of the gas oil and provides corresponding signals. A flow rate sensor provides a signal corresponding to the flow rate of the gas oil entering the heater. A control signal circuit provides the control signal to the heater in accordance with the signals from the gravity analyzer, the sulfur analyzer, the boiling point analyzer and the flow rate sensor.

Filed:

Jan 24, 1997

Appl. No.:

8/786981

Inventors:

Kenneth Roy Comey - Bellaire TX
Gerald Verdell Nelson - Nederland TX

Assignee:

Texaco Inc - White Plains NY

International Classification:

C07C 268
C07C 270

US Classification:

585725

Abstract:

A method of regulating the concentration of onium in a liquid onium poly(hydrogen fluoride) composition utilized in a hydrogen fluoride catalyzed alkylation reaction for a given level of total airborne hydrogen fluoride is disclosed. Also disclosed is a method of regulating the concentration of onium in the liquid onium poly(hydrogen fluoride) composition for a given level of RON. In one embodiment, the liquid onium poly(hydrogen fluoride composition is a mixture including pyridine and anhydrous hydrogen fluoride so as to give a pyridine poly(hydrogen fluoride) composition that is useful as a catalyst in the hydrogen fluoride catalyzed alkylation reaction.

US Classification:

364501

Abstract:

A control system controls the temperature of kerosine/diesel fuel being charged to a reactor in a hydro-treating unit. The control system includes a heater which heats the kerosine/diesel fuel in accordance with a control signal corresponding to a desired temperature. A gravity analyzer senses the API gravity of the kerosine/diesel fuel and provides a corresponding signal. A sulfur analyzer senses the sulfur content of the kerosine/diesel and provides a representative signal. A boiling point analyzer senses the 50% boiling point temperature, the initial boiling point temperature and the end point temperature of the kerosine/diesel fuel and provides corresponding signals. A flow rate sensor provides a signal corresponding to the flow rate of the kerosine/diesel fuel entering the heater. A control signal circuit provides the control signal to the heater in accordance with the signals from the gravity analyzer, the sulfur analyzer, the boiling point analyzer and the flow rate sensor.
