GSt refund

As per rule 89, Net credit means input tax credit availed on inputs and inputs services during the relevant period however does not includes ITC on capital goods therefore , ITC paid on capital goods may not be eligible for refund. It is my understanding. Please correct me if i am wrong.

QUERIST IS ASKING FOR ITC CREDIT NOT REFUND......

without asking refund from the govt. for ITC used in making zero rated supplies, what is the use of taking ITC credits ... 

YES THATS A SEPARATE ISSUE,... BUT QUERIST IS INTERESTED IN CLAIMING ITC , NOT IN REFUND (CAN SETOFF AGAINST OUTPUT TAX LIABILITIES IN FUTURE

 I think i have misunderstood subject "gst refund"
