The engineering challenge

## Conditions shaping the heating duty.

Gas withdrawal requires pressure reduction, which can sharply lower stream temperature and increase hydrate formation and blockage risks.

The mixed stream also presents wax-deposition concerns. High-pressure containment, hazardous-area operation, coastal corrosion and remote control must be addressed together.

Equipment configuration

## What the package includes.

Equipment capacities, interfaces and controls are matched to the project application.

Package count

2

Process medium

Natural gas, crude oil and produced water

Position in process

Upstream of wellhead choke-valve pressure reduction

Heat-transfer route

Indirect negative-pressure phase-change cycle

Power control

SCR regulation with PID temperature control

Environment

Outdoor winter service and coastal salt-spray exposure

Our approach

## Engineering the complete heating package.

### Process-stream isolation

Electric elements heat an intermediate fluid. Vapor condenses on the process coil and returns by gravity, keeping the heating elements separate from the high-pressure oil, gas and water stream.

### High-pressure mechanical design

The process stream flows through a pressure-rated helical coil. Pressure-retaining parts, flange interfaces, corrosion allowance and inspection strategy are selected around the application.

### Control and field protection

PLC control, a local HMI and SCR/PID regulation are combined with remote operation, temperature and pressure protection, no-flow shutdown and ESD. External coating addresses the coastal environment.

Project value

## Delivery and application value.

### Heating before throttling

The heating objective is to provide thermal margin before choke-valve pressure reduction, helping manage hydrate, wax and low-temperature blockage risks.

### Integrated field equipment

The vertical package combines high-pressure process design, indirect heat transfer and automation. No exact operating pressure or measured risk-reduction percentage is published in this case summary.
