Preheater Evaluation

Preheater Evaluation A cement plant was seeking to upgrade the size of the cyclones in their Preheater Tower which was going to modify both the framing geometry and maximum expected gravity and seismic loads on the tower.  A structural & construction evaluation was required to provide a total installed cost and schedule estimates for their […]

Tdf Electrical And Instrumentation

TDF Electrical and Instrumentation

TDF Electrical and Instrumentation A cement plant improving the efficiency of their alternate fuel sources requested that ZAP provide electrical and instrumentation design to support the integration of equipment packages into a single material handling system.  The new system would allow for the delivery of whole tires that would be shredded prior to being used […]

Power Supply Replacement

Power Supply Replacement

Power Supply Replacement ZAP replaced one of three existing power supplies serving the three glass melters. The existing 1.8MW power supply was replaced with a new 3MW variable voltage transformer and a new MV vacuum contactor and disconnect switch was installed to feed the new transformer. ZAP evaluated the existing steel structure for the installation […]

Outside Hopper Structural Support

Outside Hopper Structural Support

Outside Hopper Structural Support ZAP developed an engineered repair plan with a repair sketch for a self-supporting Lime Hopper which was struck by a moving vehicle and sustained substantial damage to a column, vertical bracing, anchor bolts, etc. ZAP completed a site visit to determine the extent of the damage and complete the repair sketch.

Monorail Update

Monorail Update

Monorail Update ZAP provided structural engineering and design to support the client in their effort to provide a turn-key solution for a monorails installed in a hazardous reagent building located on a gold concentrate facility in Colorado.  ZAP completed a site visit to visualize each of the spaces and confirm the end-user’s intent and as-built […]

Edge Trim Hopper

Edge Trim Hopper

Edge Trim Hopper ZAP completed the engineering for the replacement of the client’s edge trim re-feed hopper, blowers, and transport lines at their facility. ZAP’s design included an increase to five outputs metered using blow-through rotary valves, continuous hopper level monitoring using a laser distance sensor, five individual positive displacement blowers, the design of a […]

Relocated Silo

Relocated Silo, Foundation Design, and Permit Support

Relocated Silo, Foundation Design, and Permit Support Relocated Silo, Foundation Design, and Permit Support: ZAP performed NFPA study to determine the appropriate location of the relocated silo with respect to the deflagration vents located on it and an existing adjacent silo.  The silo is part of a sawdust collection system to expand operations of a […]

Monorail Addition

Monorail Addition at Roof

Monorail Addition at Roof A manufacturing customer wanted to add a new monorail and increase the capacity of existing monorails supported by the building roof trusses above their process equipment. ZAP provided analysis of the existing trusses, which had already been reinforced when monorails were first added.  The customer requested modifications to our design based on […]

Cyro Plant

Cryogenic Plant

ZAP was contracted by the cryogenic plant equipment packager to engineer and design the installation of a greenfield cryogenic gas plant in the Permian Basin.

Pipeline Pump Design

Pipeline Pump Design

An NGL Pipeline increased operating pressure to 1,440 psig and a client contracted ZAP to install new boost pumps to boost both Cryo plant 1 and plant 2 into the existing pipeline.

Standard Ammonia Skid Optimization

Standard Ammonia Skid Optimization

Standard Ammonia Skid Optimization ZAP assessed the hydraulic performance of the standard retail skid prototypes with the intention of determining what changes could optimize the truck loading capacity. ZAP ran simulations and aided in field testing and optimization which allowed customer to increase loading capacity to 150% of original capabilities. This increased sales revenue for […]

Soda Ash Loud Out

Soda Ash Load-Out

ZAP completed the engineering and design to modify an existing truck loadout system fed from a storage dome and from the F&I silo to meet Food Safety Modernization Act (FSMA) regulations.
