In Service September 2011 TOP: Cryogel Z being installed over the flexure ABOVE: Uninsulated gimbal joint FAR LEFT: Gimbal joint lifted into place LEFT: Gimbal joint welded to the liquid line To accommodate the accumulation of pipe strains at the base of each LNG storage tank, flexible gimbal joints were installed. By using flexible bellows and a U-joint mechanism, these piping elements could allow two simultaneous degrees of freedom in the liquid and vapor return lines. The challenge was to insulate them to the same level of thermal performance as the adjacent line pipe. To do this, 10 to 12 layers of Cryogel Z were used in a slip-joint configuration. Because the Cryogel Z remains flexible at cryogenic temperatures, it is able to follow the movements of the joint without cracking, sagging, or opening up any thru-joints.

This severe space constraint, combined with wind- and temperature-induced movements of the lines, created the need for a thin and mechanically durable insulation design. Seven 10 mm layers of Cryogel were applied to the risers and held in place with stainless steel bands. At the pipes closest approach to the stiffener rings, pre-fabricated stainless steel clamp bands were applied. These bands now provide mechanical protection where the pipe rubs against the guides and stiffener rings, and serves to support the jacketing above.

5 Sphere: Insulation and Passive-Fire Protection Location Rio Grande do Sul, Brazil Owner Braskem Engineer Odebrecht Contractor Isolenge In Service June 2010 Braskem required additional storage capacity at its Eteno Verde plant. The insulation system needed to provide both condensation control and 90 minute passive-fire protection while operating at -29 F (-34 C). A total aerogel insulation thickness of 60 mm replaced the originally specified 150mm of polyurethane foam. Braskem embraced the Cryogel Z system as a faster, cleaner technology that allowed for a more rapid commissioning of the project. Cryogel Z s fire performance was a key factor in Braskem s decision not to use traditional polyurethane foam systems.

Due to time constraints in the construction schedule, 20 mm of Cryogel Z was used in place of the cellular glass. The Cryogel Z / PIR composite offered equivalent protection against heat gain, moisture, and fire, and greater durability against mechanical damage. Most importantly, the Cryogel Z flexible blankets installed 80% faster than the cellular glass and eliminated expansion/contraction joints.

7 LNG Loading Arms Project Mejillones LNG Location Mejillones, Northern Chile Owner Tractebel Suez Engineer Technicas Reunidas Manufacturer FMC Techniologies Contractor Prezioso Loading arms are usually uninsulated due to the severe stresses of cycling between ambient and LNG (-160 C) temperatures. This can result in heavy ice formations during operation, and dangerous ice falls during the subsequent warm up. The Mejillones LNG loading arms were insulated with Cryogel Z because it is impervious to cryogenic cycling, light enough to not affect the structural dynamics, and thin enough to avoid interference with the swing mechanism. LNG loading arms in operation. Cryogel Z installed on an elbow at the base of a loading arm.

8 Everett, Massachusetts, USA Location Owner LNG Unloading and Vapor Return Lines Suez Energy Contractor Zampell In Service October 2007 Cryogel Z tie-in to adjacent insulation material. LNG loading/unloading lines in this facility commonly used rigid polyisocyanurate insulation or cellular glass. Since this facility does not continuously maintain the piping at cryogenic temperatures, the constant thermal cycling poses severe stresses on the insulation. To combat the wear-and-tear on the pipe insulation, a trial with Cryogel Z was performed in October In addition to the decreased thickness, the contractor found substantial improvements in application time. The system has been through more than 200 deep thermal cycles to date, with outstanding results.

Adriatic LNG is an offshore LNG receiving terminal located just south of Venice, Italy. Rigid insulation material was specified for the piping, but due to construction timing issues, Cryogel Z was used to insulate the cryogenic valves and flanges. Cryogel Z was chosen due to its extremely thin profile, ease of construction and logistics, and fast application time.

Cryogel Z (50 mm) All three designs meet the same condensation control criteria.

It is therefore much thinner compared to other cold insulation materials. In most cases, condensation control thickness is sufficient to meet the desired heat gain limitations.

12 Cryogel Z Flexible Industrial Insulation With Integral Vapor Barrier for Sub-Ambient and Cryogenic Applications Cryogel Z has the lowest k-value of any cryogenic insulation material in the world, reducing thicknesses by 50%-75%. Cryogel Z s flexible blanket form, with a factory-applied vapor barrier, is both faster to install and more durable once in service, resulting in lower-cost, higher-performing designs. Applications for Cryogel Z include sub-ambient piping and equipment, cryogenic storage and transport, industrial gases, and LNG import/export pipelines and process areas. Cryogel Z Insulation System Advantages 55 W/m 23 C NPS 12 (300 mm) at -170 C Cellular Glass (110 mm) PIR (100 mm) 67 W/m 23 C Thinness creates more space in and around pipe racks and equipment. Thinness can decrease the overall size of a production facility, resulting in major material reductions and cost savings. Thinness results in volume and freight savings, decreased accessory materials, minimal site storage, and simplified logistics. Unique flexible form and wrap application makes installation faster, easier, and less costly. Rigid insulation systems require numerous segments that must be effectively sealed. Will not break during shipment or once in service. Competitive with other insulation systems on an installed basis due to decreased material requirements, logistics improvements, reduced installation time, and shorter construction schedules. Cryogel Z (50 mm) All three designs meet the same condensation control criteria. 23 C 66 W/m Service Temperature Range -460 F (-270 C) to 195 F (90 C) Thermal Performance Cryogel Z has the lowest thermal conductivity of any material used for cryogenic service. It is therefore much thinner compared to other cold insulation materials. In most cases, condensation control thickness is sufficient to meet the desired heat gain limitations. Cryogel Z s minimal thickness results in a smaller surface area and reduced heat gain compared to other insulation materials. This heat gain safety factor maximizes system performance by improving process control, reducing boiloff and saving energy. Also, Cryogel Z does not have blowing agents that diffuse out over time, so its thermal performance remains constant. Moisture and Vapor Resistance Permeability to water and water vapor are critical to any insulation system operating at cryogenic temperatures. Cryogel Z uses a factory-applied mylar vapor barrier to achieve a zero-perm system. Structural Integrity Cryogel Z is well-suited for sub-ambient and cryogenic applications. Under these severe conditions, its structure experiences no thermal shock and remains totally flexible. This is unlike rigid, cellular insulation materials, which experience contraction, thermal shock, extreme stresses, damaged structure, freeze-thaw crack propagation, and degraded insulation performance under the same conditions. Dimensional Stability Cryogel Z insulation has a coefficient of thermal expansion similar to that of stainless steel, so there is minimal movement of the insulation system. Its low contraction rate and flexible wrap application eliminate the need for costly and labor-intensive expansion and contraction joints required by traditional rigid insulation systems.
