Operating Challenge

A midstream company needed to treat tens of thousands of

barrels of sour crude oil per day at a terminal site from a range

1,500 – 9,000 ppm H2S to less than 100 ppm at a pipeline delivery

location over 40 miles away. The pump equipment for the existing

scavenger solution lacked automation or data capture, and

required manual intervention and operation by the midstream

company’s operators. The operator’s fluctuations in flowrate and

crude H2S levels resulted in under or over treatment, leading to

variations in performance and cost. During critical delivery denials,

the operator would mobilize additional personnel to travel to the

terminal to monitor and make manual adjustments.

The Solution

Apollo implemented an automated H2S Treatment Solution to inject Vap-XTM Oil Blend chemistry at an adjustable rate to

efficiently and effectively treat H2S. The Vap-XTM chemistry’s high molar ratio and patented blend enable cost-effective

treatment for high H2S concentrations, without any precipitation or impact to crude quality. The treatment system uses

real-time sensor data from upstream and downstream H2S analyzers, transfer pumps, chemical pumps, and other

sensors to adjust injection rates automatically, without manual intervention. Using a remote interface module, the

system enables remote observation, management, and logging of treatment variables – including cloud-based data

logging and reporting system for treatment analysis and diagnostics.
