Abstract

A system for heating one or more sulfur transport and storage systems including a hot oil distribution system, a first transport line fluidly connecting one or more reboilers to an inlet on a heating jacket on a sulfur transport system, a second transport line fluidly connecting an outlet of the heating jacket on the sulfur transport system to an inlet on a heating coil in a sulfur storage system, and a third transport line fluidly connecting an outlet on the heating coil in the sulfur storage system to a return header on the hot oil distribution system.

First claim

What is claimed:

1. A system for heating one or more sulfur transport and storage systems, the system comprising:
a hot oil distribution system configured for feeding a first hot oil stream to one or more reboilers;
a first transport line fluidly connecting the one or more reboilers to an inlet on a heating jacket on a first sulfur transport and storage system, the first transport line configured to transport a second hot oil stream from the one or more reboilers to the inlet on the heating jacket on the first sulfur transport and storage system;
a second transport line fluidly connecting an outlet of the heating jacket on the first sulfur transport and storage system to an inlet on a heating coil in a second sulfur transport and storage system, the second transport line configured to transport a first cooled hot oil stream from the outlet of the heating jacket on the first sulfur transport and storage system to the inlet on the heating coil in the second sulfur transport and storage system;
a third transport line fluidly connecting an outlet on the heating coil in the second sulfur transport and storage system to a return header on the hot oil distribution system, the third transport line configured to transport a second cooled hot oil stream from the outlet of the heating coil in the second sulfur transport and storage system to a return header on the hot oil distribution system, and
a fourth transport line fluidly connecting the hot oil distribution system to the first transport line at a point upstream of the inlet on the heating jacket on the first sulfur transport and storage system, the fourth transport line configured to feed a hot oil makeup stream from the hot oil distribution system to the first transport line bypassing the one or more reboilers and forming an intermediate hot oil stream.

2. The system of claim 1 , wherein the first sulfur transport and storage system is a jacketed sulfur transport line.

3. The system of claim 1 , where the second sulfur transport and storage system is a sulfur storage tank.

4. The system of claim 1 , where the second hot oil stream in the first transport line is at a temperature from 285-290° F.

5. The system of claim 1 , where the second cooled hot oil stream is lower in temperature than the first cooled hot oil stream.

6. The system of claim 1 , where the hot oil makeup stream in the fourth transport line is at a temperature from 450-480° F. and the intermediate hot oil stream is at a temperature from 290-315° F.

7. The system of claim 1 , further comprising a first bypass line fluidly connecting the first transport line upstream of the inlet on the heating jacket on the first sulfur transport and storage system to the second transport line downstream of the outlet on the heating jacket on the first sulfur transport and storage system.

8. The system of claim 1 , further comprising a second bypass line fluidly connecting the second transport line upstream of the inlet on the heating coil in the second sulfur transport and storage system to the third transport line downstream of the outlet on the heating coil in the second sulfur transport and storage system.

9. A method for heating one or more sulfur transport and storage systems, the method comprising:
feeding a first portion of a first hot oil stream from a hot oil distribution system to one or more reboilers, recovering a second hot oil stream;
feeding a first portion of the second hot oil stream at a temperature from 285-295° F. from the one or more reboilers to through a first transport line to an inlet on a heating jacket on a first sulfur transport and storage system and heating a sulfur product in the first sulfur transport and storage system;
recovering a first cooled hot oil stream from an outlet on the heating jacket on the first sulfur transport and storage system;
feeding a first portion of the first cooled hot oil stream to an inlet on a heating coil in a second sulfur transport and storage system through a second transport line and heating a sulfur product in the second sulfur transport and storage system;
recovering a second cooled hot oil stream from an outlet on the heating coil in the second sulfur transport and storage system;
feeding the second cooled hot oil stream through a third transport line to a return header on the hot oil distribution system, and
feeding a second portion of the first hot oil stream from the hot oil distribution system to the first transport line at a temperature from 450-480° F. to a point upstream of the inlet on the heating jacket on the first sulfur transport and storage system, and heating the second hot oil stream to a temperature from 290-315° F.

10. The method of claim 9 , further comprising bypassing the heating jacket on the first sulfur transport and storage system with a second portion of the second hot oil stream using a first bypass line fluidly connecting the first transport line upstream of the inlet on the heating jacket on the first sulfur transport and storage system to the second transport line downstream of the outlet on the heating jacket on the first sulfur transport and storage system.

11. The method of claim 9 , further comprising bypassing the heating coil in the second sulfur transport and storage system with a second portion of the first cooled hot oil stream using a second bypass line fluidly connecting the second transport line upstream of the inlet on the heating coil in the second sulfur transport and storage system to the third transport line downstream of the outlet on the heating coil in the second sulfur transport and storage system.
