Steam / Glycol Tracing Services

ThermaTrace has a proven record of successful completion of the design and/or construction support of steam tracing installations on several large scale projects such as Petro-Canada's SIG/SIG-MOD, EDDP, RCP, CCRL. Glycol tracing services successfully provided to Husky, MEG Energy, and Brion Energy.

ThermaTrace's objective is to provide timely and cost effective Fluid Tracing design and installation services while maintaining the world class quality as proven on the previous projects. Our goal is to become and stay a second to none Canadian company specialized in Fluid Tracing.

ThermaTrace has developed an expertise in managing and producing the following key fluid tracing design deliverables as part of the overall piping design and engineering project scope:

• Creation of Manifold Location Drawings.
• An update of P & ID's as required due to the changes on Manifold Location drawings.
• Review and cross check LDT's and P & ID's.
• Red-line and drafting ST isos for module piping.
• Red-line regular isometrics and creation of Tracing Circuit Log.
• Creation of Progress report spread-sheets.
• Drafting of Fluid Tracing Iso and Manifold Installation drawings.
• Manifold Fabrication Drawings.
• Final P&ID check and tracing design due to late field design modifications or due to the changes requested by the client.
• Equipment Steam Tracing design.
• Steam Tracing BOM.

Hot Oil Tracing Services

ThermaTrace is offering hot-oil tracing systems that transfer heat by using a series of pipes in a closed loop circulation system.

Our experienced team provides total EPC solutions hot-oil tracing systems for refineries and petrochemical industry.

Design notes for hot oil tracing:

• It's necessary to select reasonable figure for glycol tracing system for dP to estimate the flow through tubing (50 psi?). 1/2" tubing is common, 0.049" wt is a common wt. Copper tubing is often used.
• Determine how much flow is possible to get through various lengths, 100 to 200 feet is a typical maximum for inplant tracing. Using that flow, estimate the inside heat transfer coefficient through the tracer. At this point, assume negligible dT.
• Now, estimate the heat transfer from the tubing surface to the air and pipe. Assume natural convection with a heat transfer resistance from the tracer to the air and then from the air to the pipe, say in the range of 1/4 to 1/2 BTU/hrft2F.

What the purpose of the above calculations is to determine whether the heat transfer from the hot glycol to the pipe is a significant portion of the overall heat transfer coefficient or if it can be neglected . Once an overall heat transfer is known for tubing lengths, you can also see if the dT of the glycol along the length is significant and has to be taken into account. If it is, it would be a good reason to limit the tracer lengths on more critical tracing applications.
